Subject RE: Problems on mac

Hi 

I first removed protobuf from brew (no install). then: 

CPATH=/usr/local/include 

DYLD_LIBRARY_PATH=/usr/local/lib 

LD_LIBRARY_PATH=/usr/local/lib 

LIBRARY_PATH=/usr/local/lib 

PATH=/usr/local/lib:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Library/TeX/texbin:/Users/Erhard/Library/Developer/android-ndk-r10e


I removed the build 

created it with: 

$ cmake .. 

$ make 

again: 

Undefined symbols for architecture x86_64:
  "google::protobuf::Message::DebugString() const", referenced from:
      singa::Channel::Send(google::protobuf::Message const&) in
channel.cc.o
 
"google::protobuf::Message::SerializeToOstream(std::__1::basic_ostream<char,
std::__1::char_traits<char> >*) const", referenced from:
      singa::Channel::Send(google::protobuf::Message const&) in
channel.cc.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see
invocation)
make[2]: *** [lib/libsinga_utils.dylib] Error 1
make[1]: *** [src/CMakeFiles/singa_utils.dir/all] Error 2 

I checked every file. in the dylib files, there are evidences, that
those two methods are in. 

Anyone other a suggestion?
