Hi, I'm running on the same problem today.

I think it's a problem with glib atomic operations and mingw, because __sync_fetch_and_sub_4 is used in g_atomic_int_dec_and_test I suppose. But I'm stuck on that.

I'm using the glib 2.30.2 build from OpenSUSE, so maybe the problem is there.

Hi All,

Updated glib to 2.30.2 and gtk+-2.0 to 2.24.8. Using gcc 4.6.1.

The latest geg download from ftp://gimptest.flamingtext.com/pub/nightly-tarballs/ is giving me the following error when building for win32 on Windows 7:

Any suggestions welcome.

Thanks, Partha

I solved this by adding the gcc options -march=pentium -mtune=pentium. See if that works for you.
