Unable to build CEF master

[danielcigloo]

Hi

I had to rebuild cef from scratch, after formatting my pc.

Of course, building CEF from latest master branch (commit #f96cd1d), as instructed in MasterBuildQuickStart - it seems like some files are missing in chromium source (i guess they were removed in recent updates)

Specifically 'chromium_git/chromium/src/build/split_static_library.gni' (there may be more files missing, its the first error i encountered)

I have searched for 'split_static_library.gni' file in latest chromium source and couldnt find it.

Here is the full error information:

Code: Select all

....

Generating CEF project files...

I guess master branch should be modified to support recent chromium changes

You need to specify the cef target.

Code: Select all

ninja -C out\Debug_GN_x86 cef

[danielcigloo]

I have not seen that error. What GN_DEFINES are you using? Do you have multiple python versions in your PATH?

[danielcigloo]

Do you have multiple python versions in your PATH?

I had, but i have removed all installations of Python (add/remove center) and issue is the same
Its most probably something that have changed on my machine, because in the recent past i have successfully built from source. (master branch, 1 month ago)
i might try setup clean VM and redo everything.

I have not seen that error. What GN_DEFINES are you using?

update.bat:

Code: Select all

set CEF_USE_GN=1
set GN_DEFINES=use_jumbo_build=true enable_precompiled_headers=false is_official_build=true proprietary_codecs=true ffmpeg_branding=Chrome
set GYP_MSVS_VERSION=2019
set GN_ARGUMENTS=--ide=vs2019 --sln=cef --filters=//cef/*
python ..\automate\automate-git.py --download-dir=c:\code\chromium_git --depot-tools-dir=c:\code\depot_tools --no-build --no-distrib


create.bat:

Code: Select all

set GN_DEFINES=use_jumbo_build=true enable_precompiled_headers=false is_official_build=true proprietary_codecs=true ffmpeg_branding=Chrome
set GN_ARGUMENTS=--ide=vs2019 --sln=cef --filters=//cef/*
call cef_create_projects.bat


[magreenblatt]

I don’t think it’s related, but you shouldn’t use enable_precompiled_headers=false with recent branches.
