I am almost sure the source of the openexr problem in cin must be an
incompatibility between the openexr versions from thirdparty and that
installed in the system: these two may be different, and while compiling
cinelerra takes headers from /usr/include/OpenEXR, but then links with the
library from thirdparty.

Here I have found my personal memo of how to compile cinelerra-4.5 (HV
version):

./configure

inspect FLAGS in *_config, *akefile on -I/usr/include/OpenEXR
change -I/usr/include/OpenEXR to -I$(includedir)/OpenEXR

make |& tee log

This means, after configure but before make I had to manually grep the whole
Cinelerra tree like this

fgrep -l I/usr/include/OpenEXR `find . -name '*akefile' -print`

Then edit in all that autogenerated makefiles all the references to
/usr/include/OpenEXR to point to the thirdparty's location, everything
manually, and only then execute make.

In my opinion, even the recent Cinelerra-HV still requires such manual
editing. But how in looks in Cin-GG, I did never inspect.

Of course, compilation of Cinelerra with openexr will succeed if by chance
the version of openexr in the system is accidentally the same as that in
thirdparty.

I am sorry, I have no time just now. Could somebody try to grep Cin-GG tree
after configure, are there some refs to headers from /usr/include which
could be conflicting with thirdparty or not?
