#### Using GCC
While we use and test Cemu using clang, using GCC might work better with your distro (they should be fairly similar performance/issues wise and should only be considered if compilation is the issue).
You can use it by replacing the step 3 with the following:
`cmake -S . -B build -DCMAKE_BUILD_TYPE=release -DCMAKE_C_COMPILER=/usr/bin/gcc -DCMAKE_CXX_COMPILER=/usr/bin/g++ -G Ninja`
#### Troubleshooting steps #### Troubleshooting steps
- If step 3 gives you an error about not being able to find ninja, try appending `-DCMAKE_MAKE_PROGRAM=/usr/bin/ninja` to the command and running it again. - If step 3 gives you an error about not being able to find ninja, try appending `-DCMAKE_MAKE_PROGRAM=/usr/bin/ninja` to the command and running it again.
