Webrtc build error "third_party/llvm-build/Release+Asserts/bin/clang++: No such file or directory"

[Tom Liu]

Hi All

I am getting errors of the following type while attempting to compile webrtc_x64 on an Ubuntu 14 system (VirtualBox). 

All gclient sync and other steps have been done as described athttp://www.webrtc.org/native-code/android. 

When I type "ninja -C out/Debug", it builds for a bit, and then I get an error like this:

[6/3105] CXX obj/webrtc/tools/agc/agc_test_utils.test_utils.o

ninja: build stopped: subcommand failed.

Is there anyone meet this issue?

Im also getting same error for mac os 10.14.4 xcode 10.1

[Alexandre GOUAILLARD]

something likely failed when you ran the "gclient sync".

this file is supposed to be compiled from automatically downloaded and patched source files for you through an "hook" in the DEPS file.

you can try to run: tools/clang/scripts/update.py

manually yourself, but usually it s just better to erase your folder, and do a full fetch => gclient sync run again.
