I'm on Debian Sid and I can't manage to compile mesa with the --enable-32-bit option whereas it works without this option. I typed this command in my shell : ./autogen.sh --with-gallium-drivers=r600 --with-dri-drivers= --enable-32-bit and the output was : [...] checking expat.h usability... no checking expat.h presence... yes configure: WARNING: expat.h: present but cannot be compiled configure: WARNING: expat.h: check for missing prerequisite headers? configure: WARNING: expat.h: see the Autoconf documentation configure: WARNING: expat.h: section "Present But Cannot Be Compiled" configure: WARNING: expat.h: proceeding with the compiler's result configure: WARNING: ## ---------------------------------------------------------------------- ## configure: WARNING: ## Report this to https://bugs.freedesktop.org/enter_bug.cgi?product=Mesa ## configure: WARNING: ## ---------------------------------------------------------------------- ## checking for expat.h... no configure: error: Expat required for DRI. I don't know if it's a mesa bug or an Autoconf bug... Thanks V.B.
I can't reproduce this. Please attach the resulting config.log, or at least the parts pertaining to expat.h.

(In reply to comment #5) > checking for XML_ParserCreate in -lexpat... no > configure: error: Expat required for DRI. That would be the libexpat1-dev:i386 package.
Looks like missing 32-bit dependent libraries. Reopen if this is actually a bug.
