Hi all,
I am a newbie trying to build mozilla-central on debian/Buster but I am
running into a compiler error. I have run bootstrap.py and have the
pulled and updated as of this email. I am running "./mach -v -log
buildlog build" and I am getting the following

I assume you mean "-l" or "--log-file" rather than "-log"

Is that the only error in the build output? It might be helpful to
attach the complete build output (preferably, directly from
stdout/stderr rather than the log file, so it's easier to read).

Also, are you specifying any non-default configuration in a .mozconfig
file or elsewhere? The file containing this error (SandboxTest.cpp)
should only be built during a debug build, so are you specifying a
debug build somewhere?

Cheers,
Botond

Could you post the generated header file
mozilla-central/obj-x86_64-pc-linux-gnu/ipc/ipdl/_ipdlheaders/mozilla/gfx/PGPUChild.h
?

Thanks,

The file is attached.

PGPUChild.h

Thanks. So, the header file is indeed missing the declaration of the
method InitSandboxTesting(). That suggests that, at the time it was
generated, this condition [1] was false.

Is it possible that you added "--enable-debug" after the build was
first started, such that the header file was generated in release mode
(making the condition false), while later parts of the build are using
debug mode, causing this mismatch?

Cheers,
Botond

Yes, that is probable. I will try clobber and rebuild...
Thanks for your help!
