[LLVMdev] LLVM-gcc for Ada

[Eric Smith]

I'm having problems building llvm-gcc for Ada, which may or may not be 
similar to the trouble Andre was having recently.  I'm trying to build 
it on Fedora 10 (32-bit), using the instructions on the web site.  The 
make terminates with a gnatbind error:

gcc -c -g -O2      -gnatpg -gnata -I- -I. -Iada 
-I../../llvm-gcc-4.2/gcc/ada ../../llvm-gcc-4.2/gcc/ada/gnat1drv.adb -o 
ada/gnat1drv.o
gnatbind -C -I- -I. -Iada -I../../llvm-gcc-4.2/gcc/ada -o ada/b_gnat1.c 
-n ada/gnat1drv.ali
error: "s-imenne.adb" must be compiled
error: ("/usr/lib/gcc/i386-redhat-linux/4.3.2/adalib/s-imenne.ali" is 
obsolete and read-only)
error: "s-imenne.adb" and "gnat1drv.adb" compiled with different 
exception handling mechanisms
make[2]: *** [ada/b_gnat1.c] Error 5
make[2]: Leaving directory `/home/eric/llvm/llvm-gcc-4.2-objects/gcc'
make[1]: *** [all-gcc] Error 2
make[1]: Leaving directory `/home/eric/llvm/llvm-gcc-4.2-objects'
make: *** [all] Error 2

Any ideas how I can fix that?  Is this happening due to using the GCC 
and Gnat 4.3 to build it?  I thought I could try installing an earlier 
version of Fedora that has GCC 4.2, but it looks like they jumped from 
4.1 to 4.3.

If there's not a simple fix, is there a Linux distro on which llvm-gcc 
with Ada is known to build "out of the box"?

Thanks!
