Error compiling ogre-next-deps using GCC 13

Post by Nucleartree »

Hi everyone. I recently tried to build ogre-next-deps on my arch linux setup. Arch being rolling release and therefore having a newer version of GCC I noticed a compiler error when building free image.

Code: Select all

In file included from /home/edward/build/ogre-next-deps/src/FreeImage/Source/OpenEXR/OpenEXR/ImfDeepTiledInputFile.cpp:12:
/home/edward/build/ogre-next-deps/src/FreeImage/Source/OpenEXR/OpenEXR/ImfDeepTiledInputFile.h:358:38: error: uint64_t has not been declared
  358 |                                      uint64_t &dataSize) const;

From doing some digging this seems to be related to a change in GCC, where you now have to explicitly define #include <cstdint>, as per this PR to OpenEXR, which is used by free image https://github.com/AcademySoftwareFound ... 1264/files However for some reason our copy/paste of this into ogre-next-deps doesn’t include this change, even though it was only updated by DarkSylinc a few months ago:

Ours: https://github.com/OGRECave/ogre-next-d ... nputFile.h
Theirs: https://github.com/AcademySoftwareFound ... nputFile.h

I was able to fix this with this change:

Code: Select all

I have tested this using a series of Docker containers as well. Ubuntu 20.04 can build the dependencies without issues, however Ubuntu latest, which is 24.04 cannot. I believe this is due to the include requirement.

Thanks!

It's always OpenEXR the one causing trouble!
Pushed your patch.
