[Qemu-devel] Build fails on OS X Lion

Hi qemu-devel,  

I tried to build the 1.1.0-rc3 on Mac OS X Lion, and I get this compile error:

qga/commands-posix.c: In function ‘qmp_guest_shutdown’:
qga/commands-posix.c:65: error: ‘environ’ undeclared (first use in this function)
qga/commands-posix.c:65: error: (Each undeclared identifier is reported only once
qga/commands-posix.c:65: error: for each function it appears in.)


If I hack in an 'extern char** environ;' to the top of that file, the build proceeds without error.

Luiz Capitulino has fixed this bug, but it haven't be merged into master branch.

Hm, I'm less certain that fix is going to work for Darwin...

I remember using a code snippet #define environ *_NSGetEnviron() or so
on Darwin.

Will check.
