Hi, I get an error when compiling (full log attached):

[ 56%] Building CXX object CMakeFiles/speedcrunch.dir/qrc_speedcrunch.o           

Linking CXX executable speedcrunch
/usr/bin/ld: CMakeFiles/speedcrunch.dir/gui/mainwindow.o: undefined reference to symbol
'XInternAtom'
/usr/bin/ld: note: 'XInternAtom' is defined in DSO /usr/lib/libX11.so.6 so try adding
it to the linker command line
/usr/lib/libX11.so.6: could not read symbols: Invalid operation
collect2: error: ld returned 1 exit status
make[2]: *** [speedcrunch] Error 1
make[1]: *** [CMakeFiles/speedcrunch.dir/all] Error 2

It builds fine with:
sed -e 's|(${PROGNAME} ${QT_LIBRARIES})|(${PROGNAME} ${QT_LIBRARIES} X11)|' -i CMakeLists.txt

Product version:
master branch

That's strange. By linking with QtGui, libX11 should be available. Can you please try
applying this patch from GitHub branch "x11" and tell me whether it works for you?

With the patch applied it complies without errors :)

Nice. Could you please check if you can build fine using QMake instead of CMake to see
if I need to patch it too?

With qmake I get the same linking error.
