fail catkin_make compilation

[rafa-chao]

Hi, I am using: ubuntu 18.04 ros melodic 1.14.10

I download to my catkin_ws folder your github, i catkin_make, but compilation doesnt work. It fails when looking for gps_common/GPSFix.h. I attach the fail:

catkin_ws/src/gps_umd/gpsd_client/src/client.cpp:2:10: fatal error: gps_common/GPSFix.h: No such file or directory

include <gps_common/GPSFix.h>

      ^~~~~~~~~~~~~~~~~~~~~

compilation terminated. gps_umd/gpsd_client/CMakeFiles/gpsd_client.dir/build.make:62: recipe for target 'gps_umd/gpsd_client/CMakeFiles/gpsd_client.dir/src/client.cpp.o' failed make[2]: [gps_umd/gpsd_client/CMakeFiles/gpsd_client.dir/src/client.cpp.o] Error 1 CMakeFiles/Makefile2:2783: recipe for target 'gps_umd/gpsd_client/CMakeFiles/gpsd_client.dir/all' failed make[1]: [gps_umd/gpsd_client/CMakeFiles/gpsd_client.dir/all] Error 2 make[1]: Waiting for unfinished jobs....

Any body knows where the problem is?

Thanks !!!!

The GPSFix.h header is generated from the GPSFix message, defined in the gps_common package. Do you also have that in your workspace? Does it try to build that before gps_umd? Could you post your entire build log?

By the way, is there a reason you need to build it from source? If you're using Ubuntu 18.04, you should be able to install pre-built binary packages instead with sudo apt-get install ros-melodic-gps*.

Hi pjreed, Yo are right, it was my fault. I clean catkin_ws, then I delete rubbish from build folder. Then I download a fresh git clone. Then I catkin_make, and finally run "rosrun gpsd_client gpsd_client" and it works.... It was my fault.

I left the software working during the night, and everything goes perfect. I just have a doubt, "status=0" doesn't change. My gps is connected to a ntrip caster service, and status should be 2. Status is working?

Thanks for your time,

Well, I used the repository source in a fresh Kinetic workspace. My gpsd is compiled via source (3.22.1~dev). Since I dislike to take care of compile sequence manually I just tried catkin_make and run into the same problem...

The following patch makes the build more robust for me.

P.S.: The GPSD_API_MAJOR_VERSION version was changed to 11 with my used gpsd version and is incompatible to the gps_umd due to changes of gps status in gps.h - but that is another story...

the same happens here. a raspberry pi 3+ buster distribution with ros noetic desktop compiled from source. you have to delete build and devel otherwise it won't generate the GPSFix.h

I think I found the issue. There was a missing dependency on catkin_EXPORT_TARGETS that could cause that node to build before the messages were built. I have cleaned up the CMakeLists.txt and package.xml files in the repo, and have issued a PR here: https://github.com/swri-robotics/gps_umd/pull/38.
