Re: [gpsd-users] test_libgpsmm.cpp

Yo Gary and thanks for responding. Ok on test_gpsmm.cpp.

I then started to add some GPSD code to my Qt C++ project, but ran into 
undefined reference problems with the first line i.e. gpsmm 
gps_rec("localhost","2947");
so I decided to start adding the source code from gpsd-3.16.tar.gz into 
my Qt project and build and link my own binaries.

> From gpsd-3.16.tar.gz I added

gps.h
gpsd_config.h
libgpsmm.h
libgpsmm.cpp

to my Qt C++ project.

Now I get an undefined reference to gps_open in libgpsmm.cpp, which 
includes libgpsmm.h and gpsd_config.h, which I have, however I am 
thinking that the implementation for gps_open would be in gps.c, but 
that is not in the package and therefore I cant put it inot my Qt 
project.

Many thanks in advance for your help.
