I resync with povray/master branch to compile on upgraded ubuntu 24.04,
since previous build is now complaining
povray: error while loading shared libraries: libIlmImf-2_5.so.25:
cannot open shared object file: No such file or directory
on config output there is:
checking for pkg-config... pkg-config
checking for OpenEXR's pkg-config... yes
checking for OpenEXR version >= 1.2... 3.1.5, ok
checking for OpenEXR/ImfCRgbaFile.h... yes
checking for ImfInputReadPixels in -lIlmImf... no
configure: WARNING: all program features using the OpenEXR library are
disabled
Is anyone already working on that ?

Mostly Ton's work from several years ago, with some help from clipka.
There was a second pull req, IIRC, for v3.7 stable (42?).

Could you try the commands
pkg-config --print-provides OpenEXR
pkg-config --libs OpenEXR
and give the results here?
Cheers
Ton.

~$ pkg-config --print-provides OpenEXR
OpenEXR = 3.1.5
~$ pkg-config --libs OpenEXR
-lOpenEXR-3_1 -lOpenEXRUtil-3_1 -lOpenEXRCore-3_1 -lIex-3_1
-lIlmThread-3_1 -lImath-3_1

These are the needed libraries. Your libIlmImf-2_5.so.25 is from the previous
EXR version, and shouldn't be tested for.
When I run configure I get
checking whether to use the OpenEXR library... yes
checking for pkg-config... pkg-config
checking for OpenEXR's pkg-config... yes
checking for OpenEXR version >= 1.2... 3.1.5, ok
checking OpenEXR/ImfCRgbaFile.h usability... yes
checking OpenEXR/ImfCRgbaFile.h presence... yes
checking for OpenEXR/ImfCRgbaFile.h... yes
My linux is
Ubuntu 24.04.1 LTS (GNU/Linux 6.8.0-48-generic x86_64)
So what I suggest is to do a "make distclean".
That removes everything, all the old configuration stuff, all object files,
makefiles.
Then configure "should" work.
Cheers
Ton
