Hi I am getting the following error when building hwloc on 32bit ubuntu 14.10 (utopic) with optimizations (CFLAGS='-O3'):
... snip ... CC topology-x86.lo /home/vagrant/src/hwloc/include/private/cpuid-x86.h: Assembler messages: /home/vagrant/src/hwloc/include/private/cpuid-x86.h:40: Error: symbol `Lhwloc1' is already defined Makefile:878: recipe for target 'topology-x86.lo' failed make[1]: *** [topology-x86.lo] Error 1 make[1]: Leaving directory '/home/vagrant/src/hwloc/hwloc' Makefile:615: recipe for target 'all-recursive' failed make: *** [all-recursive] Error 1 I used these steps to verify that the build works without optimizations and reproduce the error above with optimizations: git clone https://github.com/open-mpi/hwloc cd hwloc/ ./autogen.sh ./configure make # This works, but no optimizations. # This fails with the error above... git clean -dxf ./autogen.sh ./configure CFLAGS='-O3' CXXFLAGS='-O3' make Is this expected to work? Do you have recommendations for fixing? I first saw this on hwloc 1.9.1 and verified it also happens on 1.10.0. I attached the configure and make V=1 output, as well as the config.log for the build against master (sha: 77fbe8f) that fails. I am using the utopic32 vagrant box from Ubuntu: http://cloud-images.ubuntu.com/vagrant/utopic/current/ Please let me know if you need any other information. Thanks!
