I've been trying to make a static library out of this: https://github.com/onlinecity/cpp-smpp , as I'd like to make a single file executable that uses it.
So far I have gone into src/smpp/ and created the .o files with:
g++-5 -c *.cpp -std=c++11 -I.
Then made them into an .a file with:
ar rvs libsmpp.a *.o
Then I'm trying to compile a small main.cpp file that uses the library with this:
g++-5 main.cpp -I/usr/local/include -static libsmpp.a -lboost_system -lboost_regex -lboost_date_time -lpthread -lm -lglog -lgflags -std=c++11
And I get some undefined reference errors:

It compiles fine when I link to a dynamic version of the smpp library, although that's made using the cmake files included with the smpp lib. I didn't know how to modify them to output a static library, so I just used the g++ command at the top, and added the libraries listed in them (like glog) in the main.cpp compile command.
The "undefined reference to google::logMessage" seems especially strange, as I'm pretty sure thats part of glog, which is definitely loaded and included in the smppclient.cpp file itself.
Any ideas? Thanks.
