Hi! I'm working on a build issue on Solaris with Sun Studio. In short, I've baked it down to this:
lib_LTLIBRARIES = libprotobuf.la libprotoc.la libprotobuf_la_LIBADD = $(PTHREAD_LIBS) libprotobuf_la_LDFLAGS = -version-info 6:0:0 -export-dynamic -no-undefined libprotoc_la_LIBADD = $(PTHREAD_LIBS) libprotobuf.la libprotoc_la_LDFLAGS = -version-info 6:0:0 -export-dynamic -no-undefined make works correctly. make install produces this during the relink: CC -G -zdefs -hlibprotoc.so.6 -o .libs/libprotoc.so.6.0.0 <various .o files snipped> -R/usr/local/lib/amd64 -L/usr/local/lib/amd64 -lprotobuf -library=stlport4 -library=Crun -lpthread -lz -lc -template=no%extdef -mt -m64 -mt Undefined first referenced symbol in file void google::protobuf::internal::RepeatedPtrFieldBase::Reserve(int) .libs/command_line_interface.o void google::protobuf::internal::WireFormatLite::WriteMessageMaybeToArray(int,const google::protobuf::MessageLite&,google::protobuf::io::CodedOutputStream*) .libs/plugin.pb.o void google::protobuf::UnknownFieldSet::ClearFallback() .libs/plugin.pb.o unsigned google::protobuf::io::CodedInputStream::ReadTagFallback() .libs/plugin.pb.o void google::protobuf::internal::WireFormatLite::WriteString(int,const std::string &,google::protobuf::io::CodedOutputStream*) .libs/plugin.pb.o std::string google::protobuf::strings::CHexEscape(const std::string &) .libs/python_generator.o bool google::protobuf::internal::WireFormatLite::ReadString(google::protobuf::io::CodedInputStream*,std::string *) .libs/plugin.pb.o ld: fatal: symbol referencing errors. No output written to .libs/libprotoc.so.6.0.0 Thing is - libprotobuf.so hasn't been installed in /usr/local/lib/amd64 yet, so the -lprotobuf seems to trigger the unknown symbols above. If I remove -no-undefined from the LDFLAGS or I manually edit the above line to do: CC -G -zdefs -hlibprotoc.so.6 -o .libs/libprotoc.so.6.0.0 <various .o files snipped> -R/usr/local/lib/amd64 -L/usr/local/lib/amd64 .libs/libprotobuf.so -library=stlport4 -library=Crun -lpthread -lz -lc -template=no%extdef -mt -m64 -mt It works. Of course, I know the above editing is wrong, because it really wants to be linked with -lprotobuf. Am I just SOL in terms of being able to use -no-undefined in this case? It would be nice to get that error on the compile-for-tree stage but not have it apply to the relink for install phase. Thanks!
