Building Chromium for Windows x_86

[ArtinKennedy]

I want to build chromium for window x_86. For this, I build liboqs using this command:
cmake .. -DCMAKE_INSTALL_PREFIX=%CHROMIUM_ROOT%/third_party/boringssl/src/oqs -DOQS_USE_OPENSSL=OFF -DCMAKE_BUILD_TYPE=Release -DOQS_DIST_BUILD=OFF -DOQS_OPT_TARGET=generic

and set target_cpu = "x86" in args.gn config file. when start building of chromium, after some minutes this error occured:

[878/30595] LINK chrome_proxy.exe chrome_proxy.exe.pdb

How can I resolve this error?

Could you share all the commands you used for the build?

The linker didn't link oqs.lib. Did you apply the Windows patch?

[pi-314159]

There's an issue with the instructions.

In step 3, you have to run cd liboqs before git checkout 9aa2e1481cd0c242658ec8e92776741feabec163

Yes. I apply Windows patch. all the commands I'm using for the build are these:

cd %CHROMIUM_ROOT%
git checkout tags/124.0.6339.0
gclient sync
cd %CHROMIUM_ROOT%/third_party/boringssl/src
git remote add oqs-bssl https://github.com/open-quantum-safe/boringssl
git fetch oqs-bssl
git checkout -b oqs-bssl-master 0599bb559d3be76a98f0940d494411b6a8e0b18e
git clone https://github.com/open-quantum-safe/liboqs.git && cd liboqs && git checkout 9aa2e1481cd0c242658ec8e92776741feabec163
mkdir build && cd build
cmake .. -DCMAKE_INSTALL_PREFIX=%CHROMIUM_ROOT%/third_party/boringssl/src/oqs -DOQS_USE_OPENSSL=OFF -DCMAKE_BUILD_TYPE=Release
msbuild ALL_BUILD.vcxproj
msbuild INSTALL.vcxproj

cd %CHROMIUM_ROOT%
gn args out/Default
autoninja -C out/Default chrome

[pi-314159]

I didn’t see where you applied the patch from the commands you shared.
If you have applied the patch, you shall see libs = [ "//third_party/boringssl/src/oqs/lib/oqs.lib" ] in the file third_party/boringssl/BUILD.gn

[ArtinKennedy]

@pi-314159, because by applying patch file error occured, I apply that manually! and now libs = ["//third_party/boringssl/src/oqs/lib/oqs.lib" ] is in the file third_party/boringssl/BUILD.gn.

[pi-314159]

@ArtinKennedy Great! Sometimes whitespace etc can cause the patch to fail. I hope you can build it successfully.

If everything works out, please remember to close this issue!

[ArtinKennedy]

@pi-314159 I apply patch file. All the commands I used for the build are:

cd %CHROMIUM_ROOT%
git checkout tags/131.0.6769.0
gclient sync
cd %CHROMIUM_ROOT%/third_party/boringssl/src
git remote add oqs-bssl https://github.com/open-quantum-safe/boringssl
git fetch oqs-bssl
git checkout -b oqs-bssl-master 0599bb559d3be76a98f0940d494411b6a8e0b18e
git clone https://github.com/open-quantum-safe/liboqs.git && cd liboqs && git checkout 9aa2e1481cd0c242658ec8e92776741feabec163
mkdir build && cd build
cmake .. -DCMAKE_INSTALL_PREFIX="E:%CHROMIUM_ROOT%\third_party\boringssl\src\oqs" -DOQS_USE_OPENSSL=OFF -DCMAKE_BUILD_TYPE=Release -DOQS_DIST_BUILD=OFF -DOQS_OPT_TARGET=generic
msbuild ALL_BUILD.vcxproj
msbuild INSTALL.vcxproj
git apply oqs-Windows.patch
cd %CHROMIUM_ROOT%
gn args out/Default
append following lines to the configuration file opened in editor:

is_debug = false
symbol_level = 0
enable_nacl = false
blink_symbol_level = 0
target_cpu = "x86"
target_os = "win"

autoninja -C out/Default chrome
but errors remain:((
the command used to build liboqs for x86 is true?

[pi-314159]

Are there any files in %CHROMIUM_ROOT%\third_party\boringssl\src\oqs? Have you applied all the modifications in the patch file?
If both answers are yes, you may want to start over and re-do the entire build process.
