Is this project dead? openexr_ctl will not build with ctl and ignores --disable-ctltest

Not dead at all. We use CTL as the reference implementation language for ACES (The Academy Color Encoding System). Openexr_ctl however is a historical package. Use ctlrender for processing openexr images with one or more ctl modules.

I remember looking into the openexr viewer stuff not terribly long ago... it seems like the codebase diverged at some point, and whatever CTL module the test is looking for has long since been moved. I think I even tracked it down at some point, but in the end, it didn't help with building the openexr viewer utility. I didn't really pursue the problem much further... I think the openexr viewer stuff was built in 2004 (? could be totally wrong), and CTL development seemed to wane... Over the past four or five years, though, AMPAS and friends' contributions and restructuring (and ultimate forking off from OpenEXR itself, if I'm not mistaken) has left the original openexr viewer stuff in the dust.

If you're aiming to leverage CTL as part of a viewer buffer process, you might be happier trying the Tuttle / Natron OpenFX CTL node (can't remember what the status of that is), or having a look at @JGoldstone's nukeNode branch of his CTL fork -- the functionality is limited (for now, only the main function, if present, is evaluated, per specified NukeCtl node), but it provides a fairly direct and stable means to work / batch process with CTL...

[aforsythe]

You could always just grab the code at the tag openexr_ctl-1.0.1 https://github.com/ampas/CTL/releases/tag/openexr_ctl-1.0.1 This is where the code was when we moved it over from ILM [Δ]<http://www.oscars.org> Alex Forsythe Image Engineering Manager Academy of Motion Picture Arts and Sciences Science & Technology Council 1313 Vine Street • Hollywood, CA 90028 323.817.4170 • aforsythe@oscars.org<mailto:aforsythe@oscars.org>

Ah, thaaaat's right... good call, Alex. I think that's exactly where the "missing" CTL modules live... .../CTL/OpenEXR_CTL/CtlModules. I'm talking with our pipeline superstar right now who's been doing a lot of cross-platform builds of... everything... recently, to see if we can remember why we gave up on openexr_viewers itself.

Apparently, we were able to build, but not able to execute; and this may be a function of trying to append additional paths the $CTL_MODULE_PATH (which I think is verboten), this could very well just be a matter of keeping the missing CTLs within the singular module path... but I vaguely recall a naming conflict with the "utilities.ctl" somewhere along the line.

(In any case, I trust that openexr_viewers really should be built against openexr_ctl-1.0.1, presumably when the CTL codebase split from OpenEXR). If I have time this week, I'll see if I can further investigate / verify.

(This issue seems to duplicate issue #37 )

[themaddoctor]

That's the openexr_ctl that I tried

CTL v1.5.2 builds openexr_ctl, so you don't need the external package. Just make sure it's enabled at configure time. I had to patch both OpenEXR and CTL to get it to build right. The CMake version of OpenEXR does not install the needed Pkg-Config files, but there is a Pull Request for that.

The patches that are being used by Gentoo Linux are suitable for all distros and OSes (and submitted in PRs). You can find how we build and patch CTL here by reading the 1.5.2 ebuild file:
https://github.com/dracwyrm/gentoo-ebuilds/tree/master/media-libs/ctl

And OpenEXR viewers here by reading the 2.2.0-r1 ebuild:
https://github.com/dracwyrm/gentoo-ebuilds/tree/master/media-gfx/openexr_viewers

The IlmBase and OpenEXR are here:
https://github.com/dracwyrm/gentoo-ebuilds/tree/master/media-libs/ilmbase
https://github.com/dracwyrm/gentoo-ebuilds/tree/master/media-libs/openexr
In case you want those patches.

We are using Autotools for the OpenEXR family because that's how the ebuilds were originally done. We will switch to CMake when the mass amount of CMake issues have been fixed as our patchset would be huge to fix them all.

However, CTL and OpenEXR_Viewers fully compile and install, but you do need the .pc files installed to use Pkg-Config -- it's the best way to find all versions of OpenEXR.

The .pc files for CTL are seriously broken, so they are fixed by the patch as well.

Hope this helps.

[themaddoctor]

Thanks, Jonathan. Will try this weekend.

@themaddoctor I managed to fix the issue. You need to recompile CTL with the latest update of the patch from this PR: #67
Then compile OpenEXR_Viewers against it. :)

checking for OpenEXR... yes
Compiled and ran OpenEXR test program.
checking for OpenEXR_CTL... yes
Compiled and ran OpenEXR_CTL test program.
