[protobuf] compilation error for "undefined reference to `google::protobuf::internal::AtomicOps_Internalx86CPUFeatures'"
I have been using Ubuntu 14.04 Lts. 64Bit in Virual Machine on windows. I have some of proto files created for my project, I have been compiling complete c++ project using g++ compiler along with proto files but I am facing a compilation error below. /home/auto/Desktop/perforce/depot/project/Research/box/build64/Debug/lib/libprotobuf.a(once.o): In function `google::protobuf::internal::Acquire_CompareAndSwap(long volatile*, long, long)': /home/auto/Desktop/perforce/depot/project/Research/box/src/Components/ExternalLibraries/protobuf/2.6.0/stubs/atomicops_internals_x86_gcc.h:273: undefined reference to `google::protobuf::internal::AtomicOps_Internalx86CPUFeatures' collect2: error: ld returned 1 exit status ...failed _AWAppBuild /home/auto/Desktop/perforce/depot/project/Research/box/build64/Debug/runTime/bin/tconduit ... ...failed updating 1 target(s)... May I know what is wrong happening in compilation. However I tried adding -DGOOGLE_PROTOBUF_ARCH_X64 -DHAVE_THREAD compiler flags as well but no change.

[protobuf] Json support in protobuf 3.0.0-beta-1
Was this added ? I cant find the JsonFormat class in the api referenc The JsonFormat class was mentioned in the thread "Will protobuf support JSON?" The api is here : https://developers.google.com/protocol-buffers/docs/reference/java/index We are thinking of upgrading to protobuf 3 and want to make sure json support is there since otherwise we dont have a need to upgrade.

It seems you missed atomicops_internals_x86_gcc.cc in your build. Judging from the file path of your build, it doesn't seem like using our provided build files. > > Thanks for help in advance. > > -- > You received this message because you are subscribed to the Google Groups > "Protocol Buffers" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to protobuf+unsubscr...@googlegroups.com. > To post to this group, send email to protobuf@googlegroups.com. > Visit this group at http://groups.google.com/group/protobuf. > For more options, visit https://groups.google.com/d/optout. > -- You received this message because you are subscribed to the Google Groups "Protocol Buffers" group.
