Applies to at least 2.1.0 as well libprotobuf.lafor 2.3.0 (just committed) contains -lpthread. Is this version stable too, or are we supposed to just tolerate the older versions being broken until it is? (the two protobuf-dependent things I have tried to build fail because of this) All versions of protobuf are marked as ~arch, so yes, you need to use 2.3.0. Also you can add -lpthread on your own to link line, like: g++ -g -O2 -L/usr/lib -o protoxs perlxs_generator.o perlxs_helpers.o main.o -lprotoc -lprotobuf -lpthread 2.1.0 really should be fixed or removed... Furthermore, even 2.3.0 is still broken. Please define "broken" - you get errors while trying to merge something, compile on your own? I define "broken" as not complying with the relevant specifications, in this case the ELF format. A symptom of this brokenness is that non-threaded applications using libprotobuf will fail to link, including autoconf tests. To test: ldd /usr/lib/libprotobuf.so | grep pthread || echo BROKEN ELF file format has exactly nothing to do with what you're suggesting here. Your problem seems to be coming from misunderstanding how programs/libraries depend on each other. There are some possibilities: * use pkg-config to find paths and libraries (and in fact this is the thing that you should do for any package/library that installs pkg-config file) * use -lpthread on your command line If you still feel that there's a problem with protobuf's Makefile (linking actually) please report this upstream. Please review section 5-19 of the ELF specification: http://www.sco.com/developers/devspecs/gabi41.pdf For reference, the upstream bug is http://code.google.com/p/protobuf/issues/detail?id=103 Luke: please don't reopen this bug.
