[QGIS-Developer] Trouble compiling QGIS

[Even Rouault]

Andreas

Several things to check:

- Is your GDAL build a clean one ? That is is it from a fresh build 
directory, or are you rebuilding in a directory where a previous build 
was done. If the later, make sure to "make clean" before rebuilding

- Is your GDAL build using your custom GEOS one ? Otherwise QGIS might 
link directly to the custom one and indirectly to the system one through 
GDAL. Check the output of "ldd output/bin/qgis | grep geos"

- try "valgrind output/bin/crssync". Emitted stack traces can give 
interesting hints
