building with libstdc++

[Charles M]

ie

• use_custom_libcxx = false
• use_sysroot = false

and still get ...

  ../../third_party/libc++/src/src/condition_variable_destructor.cpp:14:10: fatal error: '__config' file not found  

any help would be greatly appreciated

You could try and run the gclient sync to fetch any missing modules, you need to run this command after you had called fetch v8 

so the order would be 

1) fetch v8 

2) git checkout <branch>

3) gclient sync 

then run the command   gn gen  out/release  --args-file=args.gn
