Unable to debug Cef 6261 build under Windows 11 Pro 23H2

[rjxray]

Starting from a D:\cef\cefbuild6261 folder which is empty except for a copy of https://bitbucket.org/chromiumembedded/ ... ate-git.py
I can successfully build the 6261 branch with the command
python3 automate-git.py --download-dir=. --branch=6261 --x64-build --with-pgo-profiles

I can run cefclient.exe with no problems from the command line in out\Debug_GN_x64

I can load cef.sln into Visual Studio 2022 but when I try to run it with the debugger I get

Code: Select all

Build started...
1>------ Build started: Project: apps, Configuration: GN x64 ------
1>'ninja.exe' is not recognized as an internal or external command,
1>operable program or batch file.

1>Done building project "apps.vcxproj" -- FAILED.


When I check PATH in a command window I see

Code: Select all

D:\cef\cefbuild6261>path
PATH=D:\cef\cefbuild6261\depot_tools;C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\WINDOWS\System32\WindowsPowerShell\v1.0\;C:\WINDOWS\System32\OpenSSH\;C:\Program Files (x86)\Windows Kits\10\Windows Performance Toolkit\;C:\Program Files\CMake\bin;C:\Program Files\dotnet\;C:\Program Files\Git\cmd;C;C:\Users\Richard\AppData\Local\Microsoft\WindowsApps;C:\Users\Richard\.dotnet\tools;c:\Utils;


ninja.exe does not exist in D:\cef\cefbuild6261\depot_tools, only ninja, ninja.bat and ninja.py. autoninja.exe does exist.

I can't find any way of making Visual Studio use autoninja.exe instead of ninja.exe

In my environment variables I have
GN_DEFINES=is_official_build=true proprietary_codecs=true ffmpeg_branding=Chrome
GN_ARGUMENTS=--ide=vs2022 --sln=cef --filters=//cef/*
I have Win 10.0.22621.1778 SDK installed

Am I doing something wrong or is there an issue here?

Maybe you need to install ninja.exe (it's just a small file), https://github.com/ninja-build/ninja/releases, and put it on the PATH, drop it in to the depot_tools folder or wherever

Thanks, that has me up and running now.

I wonder what the difference is between autoninja.exe and ninja.exe
autoninja.exe is recommended for manual building in https://bitbucket.org/chromiumembedded/ ... QuickStart

I believe autoninja.bat(?) is just a batch file that after a convoluted number of steps hands the actual work off to ninja.exe
