[QGIS-Developer] Trouble compiling QGIS

[Andreas Neumann]

Hi,

I have troubles compiling QGIS on my Linux Ubuntu 20.04 machine.

I use a self-compiled GEOS and GDAL.

The build always hangs at "crssync" - here is the ninja build output I 
get. Do you have any idea what might be wrong or what I could do in 
order to fix this problem?

Thank you for your hints,

Andreas
