How can I open openexr image on qt widget

SGaist

Did you get OpenEXR first ?

VRonin

It worked out right here but now I'm with error in the qt files
No qmake Qt5 binary found. Can't check QT_INSTALL_PREFIX

You need to run qtenv2.bat as explained in the link I posted

but has some way to do this "make" on windows

Once you selected the right generator just call cmake --build . (don't forget the dot at the end) and CMake will automatically call the correct build tool

Could not find a package configuration file provided by "KF5Archive" with

weird, KArchive is not listed as a dependency for KImageFormats. In any case it's a Tier1 Module of KDE

The following OPTIONAL packages have not been found:

KF5Archive

so it's just optional, cool.

P.S.
In my experience CMake GUI messed up my config more than it helped me build projects, I find it easier just doing it via the terminal

@SGaist Well I'm finishing compiling the remaining dependencies, but the only thing that gave me error was to install the fade pro python library "https://stefanseefeld.github.io/faber" I performed all the right steps but the system can not find directory or error on line 139

SGaist

Can you give more details about what you did and what failed ?

@SGaist I also try to compile without selecting these options python lib and openexr viewer as well as in the image. python was because I could not install the "Faber" and the viewer was because I could not install the fltk tbm

@SGaist If you have a problem with linux on linux, I would like to install linux on linux, because it is horrible to program on windows in C ++ on my opinion

Install Linux on Linux ? What do you mean by that ?

In any case, you don't really need the viewer since you want to use Qt to show the images.

Nathan Miguel

@SGaist sorry for my keyboard and brazil, sometimes it fixes the errors alone, but what I wanted to say and if it would be easier to program this in linux and if you have how to compile windows files direct in linux. But continuing, where I can find this "FLTK_GL_LIBRARY", and about python it seems that cmake is using 2.7 and not the 3.7 to install the python boost.

You don't have to link against them. They are plugins that will be loaded at run time.

You may have to add a call to QCoreApplication::addLibraryPath for your application to find them.

Nathan Miguel

@SGaist there is a problem so, cmake is not wanting to include the openexr library in kimageformat, and this makes my program compatible with psd, krikta and others except openexr

SGaist

Can you check in which OpenEXR library you have these symbols ? It's likely the llmlmf library but better double check.

Nathan Miguel

@SGaist strange, because all the libs here are good, until the includes are complete

0_1544875563064_887a0e51-2f6d-478f-a2f8-f155effb02bf-image.png

SGaist

I didn't meant you are missing a library, just wondering which one contains the missing symbols and thus if you are linking against it.

Nathan Miguel

@SGaist The log says that "moc_predefs.h" is giving the library error to generate kimg_exr.dll, more briefly, but what can I do to correct it, I tried to switch between VS and mingw

[ 1%] Automatic MOC for target kimg_exr
