             Bug #: 51972
           Summary: Compilation error on x86-64 with --enable-32-bit
                    option
    Classification: Unclassified
           Product: Mesa
           Version: git
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Mesa core
        AssignedTo: mesa-dev at lists.freedesktop.org
        ReportedBy: virgile.besson at free.fr


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.
