             Bug #: 54626
           Summary: llvmpipe's Makefile doesn't take care of CXXFLAGS or
                    CPPFLAGS
    Classification: Unclassified
           Product: Mesa
           Version: git
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Mesa core
        AssignedTo: mesa-dev at lists.freedesktop.org
        ReportedBy: alexandre.f.demers at gmail.com


When building with --enable-32-bit, I end up with:

make[4]: Entering directory
`/home/dema1701/projects/display/mesa/src/gallium/drivers/llvmpipe'
g++  -L/usr/lib32/llvm  -lpthread -lffi -ldl -lm  lp_test_format.o
lp_test_main.o -o lp_test_format -Wl,--start-group  -L../../auxiliary/

-lXxf86vm   -L/usr/lib/i386-linux-gnu/ -ldrm -lm -lpthread -ldl -Wl,--end-group

Obviously, I encounter:
collect2: error: ld returned 1 exit status
make[4]: *** [lp_test_format] Error 1

This can easily be fixed by adding "-m32" to g++. Looking through the Makefile
lets me think the flag is not properly propagated. Adding "-m32" at the end of
LDFLAGS += $(LLVM_LDFLAGS) makes sense.    LLVM_LDFLAGS is defined as    
LLVM_LDFLAGS=`$LLVM_CONFIG --ldflags` in configure.ac.

I don't know about --ldflags, but I'm sure there should be a $CFLASGS or
$CCASFLAGS there.
