Please include OpenEXR headers

[stefank]

The Haiku source code already builds the OpenEXR libraries and includes the resulting .so libraries in the distribution. It would be useful if the matching header files would also be included in the Haiku distribution so that applications can use OpenEXR.

OpenEXR should anyway be outsourced to HaikuPorts and used by the EXRTranslator through an optional package.

There should then be a dev package containing the headers. I think this already works this way for ICU. An alternative to adding the library to the system would be to statically link it within the translator.

One thing I've always hated about Debian-based Linux systems is the separation of libraries and their headers into separate packages. It sounds good in theory but in practice is annoying on Linux where almost every user is compiling something at some point.

Of course Haiku is different and should mostly have binary packages, so maybe this is OK for Haiku ;)

Though I'm generally one to dislike this sort of code duplication, I think it makes sense given how much open source libraries love to break their APIs between releases. All we need is the EXR translator (or any of them) broken because someone updated the OpenEXR library, or installed a newer one in their home directory, which our runtime_loader would load instead of the system one.

In fact we might want to do this with all our translators.

Actually I have a question for stefank:

What application is using OpenEXR? Could it be changed to use the Translation Kit on Haiku? Or does it use something special in OpenEXR?

I dunno how a dev package is supposed to be built. With a bep file?

There's a partially working .bep attached to this ticket: ​http://ports.haiku-files.org/ticket/144 But I see that the current version of openEXR is now at 1.7.1, so might update it in the process. I won't have time to do this for r1alpha4, but if someone else wants to try to get it working in time that's ok with me.

Probably should be merged in #10267.

There is already an openexr package including development files.
