[LLVMdev] bugpoint (and possibly others) need to be compiled with -rdynamic
While running the llvm tests, I get several error messages like these: [1/1] Running the LLVM regression tests FAILED: cd /home/steve/llvm-build/test && /usr/local/bin/python /home/steve/llvm/utils/lit/lit.py --param build_config=. --param build_mode=Release -sv --param llvm_site_config=/home/steve/llvm-build/test/lit.site.cfg --param llvm_unit_site_config=/home/steve/llvm-build/test/Unit/lit.site.cfg /home/steve/llvm-build/tes t -- Testing: 6378 tests, 4 threads -- Testing: 0 FAIL: LLVM :: BugPoint/metadata.ll (351 of 6378) ******************** TEST 'LLVM :: BugPoint/metadata.ll' FAILED ******************** Script: -- /home/steve/llvm-build/bin/./bugpoint -load /home/steve/llvm-build/lib/./BugpointPasses.so /usr/home/steve/llvm/test/BugPoint/metadata.ll -output-prefix /usr/ho me/steve/llvm-build/test/BugPoint/Output/metadata.ll.tmp -bugpoint-crashcalls -silence-passes > /dev/null /home/steve/llvm-build/bin/./llvm-dis /usr/home/steve/llvm-build/test/BugPoint/Output/metadata.ll.tmp-reduced-simplified.bc -o - | /home/steve/llvm-build/bin/./ FileCheck /usr/home/steve/llvm/test/BugPoint/metadata.ll -- Exit Code: 1 Command Output (stderr): -- Error opening '/home/steve/llvm-build/lib/./BugpointPasses.so': /home/steve/llvm-build/lib/./BugpointPasses.so: Undefined symbol "_ZNK4llvm4Pass11getPassNameEv" -load request ignored. bugpoint: Unknown command line argument '-bugpoint-crashcalls'.

[LLVMdev] bugpoint (and possibly others) need to be compiled with -rdynamic
Attached is a patch that fixes it for the cmake build. I'm not positive this is the right place to put it and I really have no idea where the check should go when using the autotools. -------------- next part -------------- A non-text attachment was scrubbed...

I am getting the opposite behavior: every binary is linked using -rdynamic :-( Cheers, Rafael
