runtime symbol lookup error: undefined symbol, _ZN6google10LogMessage6streamEv

[Jeff chen]

I try to use google-glog 0.3.3 in Linux Mint 17.1 as simple as follows,

#include <glog/logging.h>

int main(int argc, char* argv[]) {
     google::InitGoogleLogging("TEST");

     LOG(INFO) << "test";
}

Then compile and run it: g++ test.cpp -o test -lglog; ./test

which gives runtime error: ./test: symbol lookup error: ./test: undefined symbol: _ZN6google10LogMessage6streamEv

I initially installed glog using mint's synaptic package manager. Later I also tried to build glog from source code, and run (after removing the glog package in system): g++ test.cpp -o test -L/path/to/build/glog-lib -lglog; ./test

which still gives the same runtime error.

Would please help me to fix it? It might also be related to the gflags library, since glog depends on gflags.

Maybe you forgot to set the dependencies in your CMAKE file:

set(CPACK_DEBIAN_PACKAGE_DEPENDS  "libgoogle-glog-dev)
