Error compiling "Kimageformats" with "OpenEXR" library for qt

Nathan Miguel

Basically I'm having a problem with "moc_predefs.h" to generate kimg_exr.dll, just like it has in krita, and my openexr libraries are complete, I do not know why the imcompatibility, I already tested in the VS and MinGW compiler, and it seems that the mingw is the only one that works but that mistake is tormenting me.

PS: I'm using windows 10

PS C:\Git\kimageformats\build> cmake --build .
[ 1%] Automatic MOC for target kimg_exr

AutoMoc subprocess error

The content generation command for "moc_predefs.h" failed.

jsulm

@Nathan-Miguel Did you try to ask KImageFormat project? It is not part of Qt, so not sure anybody will be able to help you.
Also, there should be something before this line

The content generation command for "moc_predefs.h" failed.

telling what exactly failed.
