[geos-devel] Fedora 38 GCC 13 3.11.2 build failure

[Roger Bivand]

Having just  upgraded to F38, which comes with GCC 13, I deleted my unpacked tarball, uncompressed 3.11.2, and tried to build. It stopped at 
[ 51%] Building CXX object CMakeFiles/geos.dir/src/shape/fractal/HilbertEncoder.cpp.o
In file included from /home/rsb/topics/geos/geos-3.11.2/src/shape/fractal/HilbertEncoder.cpp:15:

The HEAD on github builds OK, and ctest runs cleanly; it has the #include <cstdint> declaration. Would this indicate that Fedora 38 users should build from github rather than 3.11.2, since I doubt that GCC 13 fixes are a general requirement?

Sorry for the distraction,

Roger
