[Llvm-bgq-discuss] Errors when compiling LLVM with Clang for BG/P

Thu Mar 14 15:08:59 CDT 2013

dear LLVM_BGQ list,

I'm trying to build LLVM with Clang for BG/P. I downloaded the patches 
for the r157929-20120603 revision from 
http://trac.alcf.anl.gov/projects/llvm-bgq, downloaded the corresponding 
revisions of LLVM and Clang and applied the patches. I downloaded the 
latest version of compiler-rt, since non of the patches modified 
compiler-rt, I figured that I could use the latest version. I recognize 
this may be a wrong assumption. My make eventually fails. Can someone 
offer any assistance? My download/patch/make steps are shown below, 
along with the warning/errors I get during the build.

Questions/comments:

1. Do I need to download a specific version of compiler-rt to match the 
versions of LLVM and Clang?

2. Are there any flags I should set in my environment, or as part of the 
configure command? I've seen a couple web pages that say to set 
CXXFLAGS=-UPPC or CPPFLAGS=-UPPC. Since one page said CPPFLAGS, and the 
other said CXXFLAGS, I'm dubious.

3. I know Hal Finkel provided new patches on the mailing list on 
December 13th 
http://lists.alcf.anl.gov/pipermail/llvm-bgq-discuss/2012-December/000010.html) 
(but I can't get these patches to work. One of the patche files ends 
prematurely, so the patch process fails.

4 Since I'm compiling for a BG/P and the development is focused on the 
BG/Q, I figure these newer patches in (3) probably don't really affect 
me. Right or wrong?

Thanks for your help. Build process/make errors below.
