CMake Compilers Set Incorrectly And Not Sure How to Fix It

Hi, I’m trying to compile a program to convert CK3 save files to EU4 save files. But I’m getting an error, because it looks like CMake is looking for packages called “gcc-11” and “g+±11”.
Now, I have gcc and g++ installed. I even double checked manually in my /usr/bin folder to make sure they were there in case something weird had happened. The issue seems to be that the packages I have installed are called “gcc” and “g++”, not “gcc-11” or “g+±11”.
Part of this was specified directly in one of the build scripts, so I edited it to fix that, but CMake itself still seems to be looking for gcc-11 and g+±11 after the initial point of looking at the compiler. I’m not even sure what could be causing this directly and I can’t seem to find any leads online (every similar error seems to just be people completely not having gcc or g++ installed), the errors are pretty arcane to me. Hopefully y’all can decipher them and help me figure out what the problem is. Thanks for y’all’s help!

Are you sure? :wink:

I’ve edited the only offending build script I can find.
Here’s the original:

#!/bin/bash
cd Fronter &&
rm -rf build &&
rm -rf ../Release &&
cmake -H. -Bbuild -DCMAKE_C_COMPILER=/usr/bin/gcc-11 -DCMAKE_CXX_COMPILER=/usr/bin/g++-11 &&
cmake --build build -- -j40 &&
cd ..

Here’s the fixed version:

#!/bin/bash
cd Fronter &&
rm -rf build &&
rm -rf ../Release &&
cmake -H. -Bbuild -DCMAKE_C_COMPILER=/usr/bin/gcc -DCMAKE_CXX_COMPILER=/usr/bin/g++ &&
cmake --build build -- -j40 &&
cd ..

This is the build script it’s hanging on and I did indeed edit it.

Oh, I see. It’s referencing something in the build folder. Check the scripts there.

Where is the source repo? I’d like to see the files.

5

I’ll continue to fish around in the folders to see if I can find the offending script.

It’s here:

7

Found another offending script (the main build script, in fact, I was just uh blind lol), but it’s still giving the same error, every time.

8

Search the files for the reference:

grep -iRl "g++-11" ./

I found an easy solution is just to link g++ to g+±11
ln /bin/g++ /bin/g++-11
