[QGIS-Developer] Trouble compiling QGIS

Fri Sep 3 07:49:48 PDT 2021

Hi Even,

With "valgrind output/bin/crssync" I can see that two different 
"libproj"-versions are involved with crssync:

/usr/lib/x86_64-linux-gnu/libproj.so.15.3.1

and

/usr/local/lib/libproj.so.22.1.0

I guess I will have to find out which library is still referencing the 
old libproj version - perhaps that libspatialite culprit again ...

Thanks for your hints,

Andreas
