compiler cannot create executables?

I built firefox 3.0b on win32 but it does not crash, I think because it
writes too much output. So I want to rebuild with --disable-debug. I
changed my .mozconfig and ran
make -f client.mk build
The output shows that my new .mozconfig values are used, but then the
build dies on
configure: error...C compiler cannot create executables.

How can I get it back to building again?
Thanks,
John.

If you didn't use OBJDIR, try:
$ make distclean
$ make -f client.mk build

Otherwise, just delete $OBJDIR and restart.

Thanks. I deleted obj-i686-pc-mingw32 and then tried the make cmd again.
Same error. Another idea?

What does gcc say? And have a look into config.log, that contains the
command it tried to ran and the error output it gave.

I didn't think I was using gcc on win32. I thought I was using MS
visual studio. It worked once...

Oops, yes, I missed the "win32". In any case, config.log should tell you
the command and then you can try that in the shell.

You have to make sure that your .mozconfig has unix line endings. Run,
if you have dos2unix or open it in Visual Studio and save it as unix.

Thanks, I already hit that one earlier and fixed it. That allowed me to
build the first time. Now I am struggling with the second time.

Thanks Stefan! I ignored the FAQ section because it marked as obsolete.
And the other instructions referenced use mingw32 shell: how can I use
vcvars32.bat?

The answer is: I should have run mozilla-build/start-mscv8.bat to get
mingw32 shell. It calls vcvars32.bat then puts up a shell. It even
nicely puts the title bar that would help me remember to do this next
time. But then it immediately erases the helpful bit. So I only saw
MINGW32. I fixed the FAQ page
