troubleshooting

I was getting this error:

/usr/bin/ld: /home/me/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

I ended up solving it with:

# before compiling protobuf. 
export CXXFLAGS="$CXXFLAGS -fPIC"

# And then I adjusted line 43 to link the `.so` instead of the `.a`:
export protobuf_LIBS=$HOME/local/lib/libprotobuf.so

later, turns out my binaries (mosh, mosh-client, mosh-server, protoc) were installed into $HOME/local/bin/

and I had to both add that to the PATH, and manually tell my client where to find the server binaries it with the --server option

@paulirish I was getting the same error. And I installed it by following your suggestion. However, when I run 'mosh', I had another error, 'Bareword "AI_NUMERICHOST" not allowed while "strict subs" in use at ~/mosh/bin/mosh line 489'. Any idea how to solve this problem?

This following code worked for me. I applied the export CXXFLAGS="$CXXFLAGS -fPIC" as paulirish mentioned. However, I used libprotobuf.a instead of libprotobuf.so because I got weird errors whenever I tried to use libprotobuf.so. If you still can't use mosh after running the following code, try using the --server option in mosh.

mkdir mosh
cd mosh

ROOT=`pwd`

echo "about to set up everything in $ROOT"

mkdir build
mkdir install

cd build
curl -O https://codeload.github.com/google/protobuf/tar.gz/v3.4.0
curl -O https://mosh.org/mosh-1.3.2.tar.gz
tar zxvf v3.4.0
tar zxvf mosh-1.3.2.tar.gz

@jzhan039 I'm having the same issue. Did you ever solve it?
