Problem met when compiling in WSL2

[ttzytt]

I was trying to compile the project in WSL2 (ubuntu) following the documentation. When running the last step, some errors were generated:

It seems that the line moc: /mnt/e/prog/pris_research/openMVG/src/openMVG_Samples/describe_and_match_GUI/MainWindow.hpp: No such file is complaining some files cannot be found. However, after inspecting the directory, I found that this file actually exists.

Any idea of what's happening? Thanks!

Maybe an issue with the version of QT. Can you try build without the QT samples?

[ttzytt]

Thank you for your quick response.

I'm not sure how exactly I should disable QT. I took a look at the cmake files and did this; not sure if it is right, though:

After this, I run the following two commands:

cmake -DCMAKE_BUILD_TYPE=RELEASE ../openMVG/src/
cmake --build . --target install

And got pretty much the same result:

Output
------
moc: /mnt/e/prog/pris_research/openMVG/src/software/VO/AlternativeVO/MainWindow.hpp: No such file

[pmoulon]

Can you add -DOpenMVG_BUILD_GUI_SOFTWARES=OFF to the cmake command line (with emptying your cmake cache

[ttzytt]

Wow! It worked. Thanks a lot!

Then, what should I do for the next step to enable the GUI functionalities? I have already installed QT5 in my environment.

@rperrot any idea what could be wrong with the sample. I'm not sure how behave Qt with WSL...
