+
+This contains .gn files, scripts, and other artifacts like vdpau-va-driver and flash player and the BUILDER file which contains notes (generally only usable by me, but feel free to ask what the info inside is for).
+
+The args.list file shows all possible build arguments, and the gn_args.list shows all possible build args after the Thorium args have been added, and the win_args.list shows all possible build arguments for Windows builds.
+
+The *.gn files contain what you should use in the args.gn for platforms other than the normal Linux release (which is in the root of this repo.)
+ - 69_release_args.gn is for Chromium 60-70 versions.
+ - android_args.gn is for Android ARM64. > https://chromium.googlesource.com/chromium/src/+/main/docs/android_build_instructions.md
+ - cros_args.gn is for ChromiumOS on Linux. > https://chromium.googlesource.com/chromium/src/+/main/docs/chromeos_build_instructions.md#Chromium-OS-on-Linux-linux_chromeos
+ - mac_args.gn is for x64 macs.
+ - windows_args.gn is for Windows x64
+
+ – The WIN_INSTRUCTIONS.txt and WIN_CROSS_BUILD_INSTRUCTIONS.txt are for how to build Thorium for Windows natively and on Linux, respectively.
+
+ – The thorium_devel_bookmarks.html file contain the bookmarks I use for Thorium development and rebasing the files it uses.

+## These are instruction for cross building Thorium for Windows, on Linux. Preliminary file for @gz83, to be eventually migrated to a Wiki with building instructions for all paltforms.
+## Copyright (c) 2022 Alex313031
+
+## In general, this document follows information from > https://chromium.googlesource.com/chromium/src.git/+/HEAD/docs/win_cross.md and https://chromium.googlesource.com/chromium/src/+/main/docs/linux/build_instructions.md
+
+## Preparatory setup
+First, make sure you are running Ubuntu 18.04/20.04, or Debian 10/11, or Arch, and have nano and unrar installed.
+
+First, we need to install depot_tools. depot_tools is a .zip that contains tools for all Google projects like Chromium, ChromiumOS, NaCl, V8, Infra, Android, Google Cloud, and Fuschia.
+
+We are assuming that depot_tools, chromium, and thorium will all be in $HOME.
+
+First, (in $HOME), download depot_tools.
+
+git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git
+
+Then, open your .bashrc and add these to the end. (SUBSTITUTING FOR THE ACTUAL PATH, I.E. mine says alex because my name is Alex lol.)
+
+umask 022
+export EDITOR=nano
+export VISUAL=nano
+export NINJA_SUMMARIZE_BUILD=1
+export PATH=/home/alex/depot_tools:$PATH
+export DEPOT_TOOLS_WIN_TOOLCHAIN_BASE_URL=/home/alex/chromium/win/
+export GYP_MSVS_HASH_1023ce2e82=b86447e8fb
+
+Then make these dirs
+
+mkdir ~/chromium
+mkdir ~/chromium/win
+
+Then cd ~/chromium, and run
+
+fetch --nohooks chromium
+
+Let it download, it is large.
+Then cd ~/chromium/src, and run
+
+./build/install-build-deps.sh --no-arm --lib32
+
+Then run
+
+gclient runhooks
+
+We now have a Chromium checkout, however we need to modify the .gclient file to download Windows dependencies.
+
+Edit the .gclient file in chromium (not chromium/src)
+
+And append to the bottom this line:
+
+target_os = [ 'linux', 'win' ]
+
+Lastly, cross building requires artifacts from Visual Studio as per > https://chromium.googlesource.com/chromium/src.git/+/HEAD/docs/win_cross.md
+
+Download a .zip I already made from here > https://github.com/Alex313031/Snippets/releases/tag/10.1.20348.1
+
+And place it in ~/chromium/win
+
+## Setting up Thorium
+
+Now, lets download the Thorium tree, so run (in $HOME)
+
+git clone https://github.com/Alex313031/Thorium.git OR
+
+Download the latest .zip > https://github.com/Alex313031/Thorium/archive/refs/heads/main.zip
+
+Then cd ~/Thorium, and we need to make some files executable. So run
+
+sudo chmod +x build.sh
+sudo chmod +x build_win.sh
+sudo chmod +x setup.sh
+sudo chmod +x trunk.sh
+sudo chmod +x clean.sh
+sudo chmod +x misc/autoninja
+
+## Setting up the build
+Then, run (in order)
+
+./trunk.sh // Pay attention to the PGO profile that is downloaded, the script downloads the PGO profile *.profdata files for Linux, Windows, and MacOS.
+./setup.sh
+
+Now we need to set up the PGO profile and set the args.gn
+
+Open ~/Thorium/misc/windows_arg.gn and edit the last line that looks like
+
+/home/alex/chromium/src/chrome/build/pgo_profiles/chrome-win64-main-1649213807-91f73deff0cf33b43bdbec74d7cefebdfe29830a.profdata
+
+And edit it to point to the actual location of that PGO file from above.
+You can also add API Keys to the top three lines of this file to enable Google Sync, Translate, etc. (Out of the scope of this article, for help, contact me.)
+
+Now, go to ~/chromium/src, and run
+
+gn args out/thorium
+
+A nano editor will come up, and you will copy/paste the contents of the windows_args.gn file into this.
+Save and exit and the terminal will show "Generating files..." Wait for it to complete, and then to actually build it:
+
+Go back to ~/Thorium, and run ./build_win.sh
+
+NOTE: Run ./build_win.sh --help to see the (only) option, which is the number of jobs. The command it ultimately runs is:
+./misc/autoninja -C ~/chromium/src/out/thorium chrome chromedriver content_shell setup mini_installer -j
+
+You can substitute the -j# for the number of jobs. I use 8 because I have an 8 core cpu. Do not use a number more than the number of threads your CPU has.
+
+So for example, I run ./build_win.sh 8
+
+In the end, you will have a nice installer called mini_installer.exe in ~/chromium/src/out/thorium/
+
+I rename it to thorium_mini_installer.exe or thorium_avx2_mini_installer.exe for releases. Just double click to install Thorium to C:\Users\$USERNAME\AppData\Local\Thorium
+
+## AVX2 Release
+
+Speaking of which! Thorium by default compiles with AVX and AES. To make the AVX2 version of it, you will follow all the steps above, except before running gn args out\thorium,
+we need to download the avx2 sources.
+
+git clone https://github.com/Alex313031/Thorium-AVX2.git or https://github.com/Alex313031/Thorium-AVX2/archive/refs/heads/main.zip
+
+And simply copy the build directory over ~/chromium/src/build
+
+## Make a portable release.
+To make a portable release, it is easiest to copy an already made portable release from GitHub, extract it, and then:
+
+1. Delete the contents of the BIN folder.
+
+2. Use 7-Zip to extract the contents of the new mini_installer you just made, and then extract the chrome.7z that was inside it.
+
+3. Copy the contents of Chrome-bin into the BIN folder in the portable folder.
+
+4. Edit CONTENT_SHELL.bat to point to the actual location as the version number will have changed.
+
+5. Likewise, edit the version number in the name of the whole portable folder to reflect the new Thorium.
+
+6. Finally, rezip it up with 7-Zip. To use it, read the README.txt inside.
+
+## Updating your checkout
+
+To update the Chromium checkout, just run (from ~/Thorium)
+
+./trunk
+
+To update Thorium, do a git pull main or redownload the latest .zip
+
+Enjoy!

+## These are instruction for building Thorium for Windows, natively on Windows. Preliminary file for @gz83, to be eventually migrated to a Wiki with building instructions for all paltforms.
+## Copyright (c) 2022 Alex313031
+
+## Preparatory setup
+First, we need to install depot_tools and Visual Studio. depot_tools is a .zip that contains tools for all Google projects like Chromium, ChromiumOS, NaCl, V8, Infra, Android, Google Cloud, and Fuschia.
+
+We will be in general following instructions from > https://chromium.googlesource.com/chromium/src/+/main/docs/windows_build_instructions.md
+
+Visual Studio 2019 or 2022 is needed, and the Windows SDK version 10.0.20348.0 is needed along with its Debugging Tools.
+
+EVERYTHING in this document is to be done in command prompt. No powershell, no windows terminal (Win 11).
+
+The easiest way to do this is (and even if you already have Visual Studio installed, go ahead and redownload the latest installer to do this)
+(VISUAL_STUDIO_INSTALLER is the actual path/name of the installer .exe)
+$VISUAL_STUDIO_INSTALLER --add Microsoft.VisualStudio.Workload.NativeDesktop --add Microsoft.VisualStudio.Component.VC.ATLMFC --includeRecommended
+
+As noted above The SDK Debugging Tools must also be installed. If the Windows 10 SDK was installed via the Visual Studio installer, then they can be installed by going to:
+Control Panel → Programs → Programs and Features → Select the “Windows Software Development Kit” → Change → Change → Check “Debugging Tools For Windows” → Change.
+
+Then download depot_tools. We are assuming that depot_tools, chromium, and thorium will all be in C:\src\.
+
+https://storage.googleapis.com/chrome-infra/depot_tools.zip
+
+Then, If you have Administrator access, Modify the PATH system variable and put C:\src\depot_tools at the front (or at least in front of any directory that might already have a copy of Python or Git).
+Also, add a DEPOT_TOOLS_WIN_TOOLCHAIN environment variable in the same way, and set it to 0. This tells depot_tools to use your locally installed version of Visual Studio
+(by default, depot_tools will try to use a google-internal version).
+Also, add a NINJA_SUMMARIZE_BUILD environment variable the same way, and set it to 1.
+
+Then, go to C:\src in cmd, and run
+
+gclient
+
+Now, lets configure git (you can skip the user.name and user.email if it is already configured)
+
+git config --global user.name "My Name"
+git config --global user.email "my-name@chromium.org"
+git config --global core.autocrlf false
+git config --global core.filemode false
+git config --global branch.autosetuprebase always
+
+Now let's make the chromium dir.
+
+mkdir chromium && cd chromium
+
+So you should be in C:\src\chromium
+
+Now run
+
+fetch chromium
+
+Let it download, it is large.
+
+Then cd src\v8, so that we are in C:\src\chromium\src\v8, and run (one after another)
+
+git checkout -f origin/main
+
+cd ..
+
+git checkout -f origin/main
+
+git rebase-update
+
+git fetch --tags
+
+gclient sync --with_branch_heads --with_tags -f -R -D
+
+gclient runhooks
+
+Good, now we have a full Chromium checkout ready to be built, but to turn it into Thorium, we must copy the Thorium sources over the Chromium tree.
+
+## Thorium Setup
+So, lets download Thorium in C:\src
+
+git clone https://github.com/Alex313031/Thorium.git or download the .zip and unpack it there > https://github.com/Alex313031/Thorium/archive/refs/heads/main.zip
+
+Now, go back to C:\chromium\src
+
+We are going to download the PGO profile (which changes with every release) so that we can set it in our args.gn file, which ninja (the build system) parses before compiling. So run
+
+python3 tools/update_pgo_profiles.py --target=win64 update --gs-url-base=chromium-optimization-profiles/pgo_profiles
+
+Now pay attention to the the file that is downloaded.
+
+In C:\src\Thorium\misc, there is a file called windows_args.gn. In that file toward the bottom there will be a line that says
+pgo_data_path = "/home/alex/chromium/src/chrome/build/pgo_profiles/chrome-win64-main-1649213807-91f73deff0cf33b43bdbec74d7cefebdfe29830a.profdata"
+
+We are going to change that to the actual location and name of the PGO profile data file we just downloaded i.e. it should look similar to this:
+
+C:\src\chromium\src\chrome\build\pgo_profiles\chrome-win64-main-1649213807-91f73deff0cf33b43bdbec74d7cefebdfe29830a.profdata
+
+You can also add API Keys to the top three lines of this file to enable Google Sync, Translate, etc. (Out of the scope of this article, for help, contact me.)
+
+Now, we are going to copy the Thorium sources. Select (via Ctrl + Left Mouse button) these folders in C:\src\Thorium:
+
+build, chrome, components, content, media, net, sandbox, third_party, tools, ui, v8
+
+Then paste these in C:\chromium\src (overwriting everything)
+
+Now, we are going to set up the build.
+
+Go to C:\src\chromium\src and run
+
+gn args out\thorium
+
+It will pull up notepad. Copy and paste the contents of the windows_args.gn we just edited into notepad, save it, and then exit notepad. Cmd will show "generating files..."
+
+But wait, we also need to cherry pick some files from Thorium and copy them into C:\src\chromium\src\out\thorium (These are things like logos, the pak binaries, etc. that are thorium specific)
+
+content_shell\thorium-devtools.ico and content_shell\thorium-devtools.png AND
+
+All the files in pak_src\bin\pak-win
+
+## Compilation
+Finally, we are ready to compile Thorium!
+
+Make sure you are in C:\src\chromium\src
+
+And run:
+
+autoninja -C out\thorium chrome chromedriver content_shell setup mini_installer -j8
+
+You can substitute the -j# for the number of jobs. I use 8 because I have an 8 core cpu. Do not use a number more than the number of threads your CPU has.
+
+In the end, you will have a nice installer:
+
+C:\src\chromium\src\out\thorium\mini_installer.exe
+
+I rename it to thorium_mini_installer.exe or thorium_avx2_mini_installer.exe for releases. Just double click to install Thorium to C:\Users\$USERNAME\AppData\Local\Thorium
+
+## AVX2 Release
+
+Speaking of which! Thorium by default compiles with AVX and AES. To make the AVX2 version of it, you will follow all the steps above, except before running gn args out\thorium,
+we need to download the avx2 sources.
+
+git clone https://github.com/Alex313031/Thorium-AVX2.git or https://github.com/Alex313031/Thorium-AVX2/archive/refs/heads/main.zip
+
+And simply copy the build directory over C:\src\chromium\src\build
+
+## Portable release
+To make a portable release, it is easiest to copy an already made portable release from GitHub, extract it, and then:
+
+1. Delete the contents of the BIN folder.
+
+2. Use 7-Zip to extract the contents of the new mini_installer you just made, and then extract the chrome.7z that was inside it.
+
+3. Copy the contents of Chrome-bin into the BIN folder in the portable folder.
+
+4. Edit CONTENT_SHELL.bat to point to the actual location as the version number will have changed.
+
+5. Likewise, edit the version number in the name of the whole portable folder to reflect the new Thorium.
+
+6. Finally, rezip it up with 7-Zip. To use it, read the README.txt inside.
+
+## Updating your checkout
+
+To update the Chromium checkout, just run the same commands from above (in C:\src\chromium\src\v8\)
+
+git checkout -f origin/main
+
+cd ..
+
+git checkout -f origin/main
+
+git rebase-update
+
+git fetch --tags
+
+gclient sync --with_branch_heads --with_tags -f -R -D
+
+gclient runhooks
+
+To update Thorium, do a git pull main or redownload the latest .zip
+
+Enjoy!

+ Current value (from the default) = true
+ From //media/media_options.gni:155
+
+ On Android, FFMpeg is built without video decoders by default.

+ Current value (from the default) = false
+ From //build/config/compiler/BUILD.gn:70
+
+ Compile in such a way as to make it possible for the profiler to unwind full

+
+enable_iterator_debugging
+ Current value (from the default) = false
+ From //build/config/c++/c++.gni:41
+
+ When set, enables libc++ debug mode with iterator debugging.
+
+ Iterator debugging is generally useful for catching bugs. But it can
+ introduce extra locking to check the state of an iterator against the state
+ of the current object. For iterator- and thread-heavy code, this can
+ significantly slow execution - two orders of magnitude slowdown has been
+ seen (crbug.com/903553) and iterator debugging also slows builds by making
+ generation of snapshot_blob.bin take ~40-60 s longer. Therefore this
+ defaults to off.

+ From //build/config/logging.gni:11
+
+enable_logging_override
+ Current value (from the default) = false
+ From //media/media_options.gni:75
+
+ Enable logging override, e.g. enable DVLOGs through level 2 at build time.
+ On Chromecast, these are logged as INFO.
+ On Fuchsia, these are logged as VLOGs.
+
+enable_maldoca

+
+enable_media_remoting_rpc
+ Current value (from the default) = true
+ From //media/media_options.gni:268
+
+ Media Remoting RPC is disabled on Android since it's unused but increases
+ the native binary size by ~70Kb.
+
+enable_message_center

+
+enable_mojom_typemapping
+ Current value (from the default) = true
+ From //mojo/public/tools/bindings/mojom.gni:33
+
+ Indicates whether typemapping should be supported in this build
+ configuration. This may be disabled when building external projects which
+ depend on //mojo but which do not need/want all of the Chromium tree
+ dependencies that come with typemapping.
+
+ Note that (perhaps obviously) a huge amount of Chromium code will not build
+ with typemapping disabled, so it is never valid to set this to |false| in
+ any Chromium build configuration.
+
+enable_mse_mpeg2ts_stream_parser
