[PD] help compiling recent GEM

[mick mengucci]

Hi Johannes,

I get the bug of the inverted colors in version of Gem
ver: 0.93.git 8032816

today I tried to compile the version taken from
https://github.com/umlaeute/Gem

but I get this error:

...
gemglxwindow.cpp:670:4: warning: #warning context-sharing disabled [-Wcpp]
gemglxwindow.cpp: In member function 'virtual bool gemglxwindow::create()':
gemglxwindow.cpp:707:35: error: 'snprintf' was not declared in this scope
make[1]: *** [gemglxwindow_la-gemglxwindow.lo] Error 1
make[1]: Leaving directory
`/home/mick/Documents/LabIO/gits/SonarX/Gem/src/Output'
make: *** [all-recursive] Error 1

Thank you,
Mick
