Hi people,
I'm trying to run mosh on centos 6 machines. And to a large extent, I have succeeded to do that in the "normal" way. ie: compile stuff on the machines I will use, and modify LD_LIBRARY_PATH adequately. What I'm trying to do now is avoid having to modify the LD_LIBRARY_PATH env on all machines, avoid having to compile protobuf on all machines. Since I need to do that because of protobufs, I'm looking for a way to statically link protobuf into the binary then distributed that. I have so far failed. When I statically compile the whole binary, I run into problems with glibc (because of nss mostly, and missing dlopen, dl* symbols), and when I try to statically link only /usr/local/lib/libprotobuf.a, I run into trouble at link time for this library. I compile protobufs like this: ./configure (tried --disable-shared and --static and both without success, the error is always the same when compiling mosh) make make install (goes to /usr/local/lib/protobufs....) Then I compile mosh like so: ./configure protobuf_LIBS="/usr/local/lib/libprotobuf.a" PKG_CONFIG_PATH="/usr/local/lib/pkgconfig/" make And after a little while I get this : CXXLD mosh-client /usr/bin/ld: /usr/local/lib/libprotobuf.a(common.o): relocation R_X86_64_32S against `std::basic_string<char, std::char_traits<char>, std::allocator<char> >::_Rep::_S_empty_rep_storage' can not be used when making a shared object; recompile with -fPIC /usr/local/lib/libprotobuf.a: could not read symbols: Bad value collect2: ld returned 1 exit status make[3]: *** [mosh-client] Error 1 make[3]: Leaving directory `/root/Downloads/mosh-1.2.5/src/frontend' make[2]: *** [all-recursive] Error 1 make[2]: Leaving directory `/root/Downloads/mosh-1.2.5/src' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/root/Downloads/mosh-1.2.5' make: *** [all] Error 2 Don't know how to make this work... If I replace libprotobuf.a by libprotobuf.so, it compiles ok, but checking with ldd, the binaries produced do dynamic linking against libprotobuf.so, which is what I'm trying to avoid. I can't wrap my head around what exactly does protobuf_LIBS and the interaction with PKG_CONFIG_PATH, so perhaps there is something there... Thanks for any help !
