How can I open openexr image on qt widget

[Nathan Miguel]

@VRonin @mrjj It worked out right here but now I'm with error in the qt files

@Nathan-Miguel I guess you need to use MinGW

[Nathan Miguel]

@jsulm I used mingw but it gave an eros too.

CMake Error at CMakeLists.txt:3 (project):
The CMAKE_C_COMPILER:

cl

is not a full path and was not found in the PATH.

To use the NMake generator with Visual C++, cmake must be run from a shell
that can use the compiler cl from the command line. This environment is
unable to invoke the cl compiler. To fix this problem, run cmake from the
Visual Studio Command Prompt (vcvarsall.bat).

Tell CMake where to find the compiler by setting either the environment
variable "CC" or the CMake cache entry CMAKE_C_COMPILER to the full path to
the compiler, or to the compiler name if it is in the PATH.

@jsulm @mrjj @VRonin is almost, I just need to find this folder that is highlighted and know how to include openexr libraries

Did you get OpenEXR first ?

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

[Nathan Miguel]

@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

[Nathan Miguel]

@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

[SGaist]

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.

@SGaist Sorry bother, but now I've been able to install everything, thanks to everyone, but how can I include this in my project

[VRonin]

@Nathan-Miguel said in How can I open openexr image on qt widget:

but how can I include this in my project

http://doc.qt.io/qt-5/third-party-libraries.html
http://doc.qt.io/qtcreator/creator-project-qmake-libraries.html

[Nathan Miguel]

@VRonin only have a problem, I just see these files for me and what does not accept other formats of includes other than .h, .lib, .a

[SGaist]

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

[Nathan Miguel]

@SGaist I was able to make cmake find them but I still have an error compiling openexr's ".lib"
