Error when building RC Object (Application Icon)

[Aadnesid]

Hi, I am currently trying to get an application icon working for my test program. I am using cmake for this.

I've made a .rc file and tried to follow the steps the guide was telling me to do. Currently I am stuck when building the cmake file which gives me the build error:

"[2/13 0.5/sec] Building RC object CMakeFiles/Project-2022v.dir/icons.rc.obj
FAILED: CMakeFiles/Project-2022v.dir/icons.rc.obj

I've double checked that the icons are relative to the rc file and that the file is reachable. But I am pretty confused as to why the error names the .rc file extension plus a .obj. If that's the cause, how do I fix this?

Cheers,
Aadne.

Can you share your CMakeLists file and the compiler output?

[VRonin]

There is nothing special to do, you just need to add the .rc file as you would a .cpp file.
What is the content of the .rc file?

[Aadnesid]

That's what I figured.
Here is the contents of the .rc file aswell as my directory

Here is my cmake file, incase you spot any dumb errors on my part.
Icons.rc is set under "Project Sources" at the bottom.

cc1.exe: fatal error: 2022/Program/build-Project-2022v-Desktop_Qt_6_2_4_MinGW_64_bit-Debug: No such file or directory

Even though I think it shows quoted ("...") correctly, the error message shows that somewhere it is treating your

"C:/Users/aadne/ikt103g22v/assignments/solutions/Prosjektoppgave 2022/Program/..." 

path as two separate elements, broken at the space inside Prosjektoppgave 2022, hence the 2022/Program/... of the error message.

Simplest would be not to use a path with a space in it? I think there have been other occasions where Qt builds have problems with path names with spaces like this....

[Aadnesid]

@JonB You are totally right in that regard, after replacing that space with a simple "_" (and all the other stuff regarding fixing paths in cmake etc.) it finally works.

So lesson learned, avoid using spaces and such in file directories.
Thanks a ton!

Cheers,
Aadne.
