[Mesa-dev] Woes of --enable-32-bit on x86-64 Fedora 15

[Ian Romanick]

Building the i965 driver with --enable-32-bit is just broken on Fedora 
15.  It seems to work for folks on other distros, but I get a lot of 
failure during linking i965_dri.so.  Linking i915_dri.so works, and the 
difference seems to be the presence of C++ files in i965.

The generated libtool script has *tons* of references to lib64 and 
/usr/lib/gcc/x86_64-redhat-linux/4.6.3/**.

I have tried adding --host=i686-redhat-linux to the configure line, but 
that had no affect.

Setting LDFLAGS with a bunch of -L options for 32-bit library paths 
fixes all of the 'skipping incompatible lib' messages, but the hardcoded 
references to crt*.o still fail.

The errors I get are
