[gpsd-users] help with test_gpsmm.cpp

Hello

Has anyone tried to compile the test_gpsmm.cpp script that is included in the package (gpsd-3.9)?

I tried it and ran into problems. This is the command I used
g++ test_gpsmm.cpp libgpsmm.cpp

It didn't compile and I got the following errors

/tmp/ccJXzj5b.o: In function `libgps_dump_state(gps_data_t*)':
test_gpsmm.cpp:(.text+0x1c): undefined reference to `gps_maskdump'
/tmp/ccM4smxK.o: In function `gpsmm::gps_inner_open(char const*, char const*)':

libgpsmm.cpp:(.text+0x1d6): undefined reference to `gps_close'
collect2: error: ld returned 1 exit status

gps_open, gps_stream etc are all functions in gps.h which is mentioned in libgpsmm.h

I figured if I didn't have gpsd running and if the program compiled, I should get an error message saying "No gpsd running". I can't seem to get that because it didn't compile.

Any thoughts?

Thanks
