Bug 360001 – kde-base/marble-4.6.1 automagically detects gpsd, ignoring the "gps" use flag.

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Kevin McCarthy (RETIRED) 2011-03-22 21:11:10 UTC]

I had sci-geosciences/gpsd installed without the "qt4" use flag set and decided to emerge kde-meta. I was only using gpsd for testing another package, so I do not have the "gps" use flag set. When it got to kde-base/marble it failed to compile:

[ 95%] Building CXX object marble/src/plugins/positionprovider/gpsd/CMakeFiles/GpsdPositionProviderPlugin.dir/GpsdConnection.o

compilation terminated.

If I rebuild gpsd with the "qt4" USE flag, marble compiles cleanly, but still builds the GpsdPositionProviderPlugin, even with USE="-gps". If I remove gpsd from my system marble builds without the GpsdPositionProvider.

It would appear that marble's build system is detecting the presence of gpsd on my system and enabling support if it finds it, even if I have the gps use flag unset:

% emerge -pv marble

These are the packages that would be merged, in order:

% qlist marble | grep Gpsd
/usr/lib64/kde4/plugins/marble/GpsdPositionProviderPlugin.so

Reproducible: Always

Steps to Reproduce:
1. Install sci-geosciences/gpsd
2. emerge kde-base/marble with USE="-gps"
3.
Actual Results:  
/usr/lib64/kde4/plugins/marble/GpsdPositionProviderPlugin.so is built and installed.

Expected Results:  
GpsdPositionProviderPlugin.so should not be built.

Yep it is automagic.
