#include <cstdint> issue

[HuidaeCho]

I had to #include <cstdint> in some C++ files for geos, synergy, and xournalpp. Is it an issue in my Slackware-CURRENT install?

Found this post, but no idea how to update to the "source tree"

this is a pretty common issue when trying to build many upstream projects with gcc >= 13.x (shipped in current since a few weeks), it's explained also on the gcc site itself

https://gcc.gnu.org/gcc-13/porting_to.html

either you wait for new versions of the upstream software (verifying that are compatible with the rest of our scripts, dependencies or dependees) or you, like you seem to have already done, patch the headers shipped with the sources including cstdint, like most of the times gcc 13.x already suggests you.
if you have already assembled patches that can be used while running the interested SlackBuild they are welcome!
