+#### GCC Errors (Pop!_OS 22.04)
 
-```bash
-make CUDAPATH=/usr/lib/cuda
+On some versions of Pop!_OS and Ubuntu (including 22.04), the default version of GCC may fail to compile gpu-burn. Install a compatible version with this command:
+
+```
+sudo apt install g++-10
+```
+
+Then, run `make` again, specifying which version of GCC to use:
+
+```
+make NVCCFLAGS='-ccbin /usr/bin/g++-10'
 ```
 
-(If you receive an error about your version of GCC being too new, consider installing the appropriate version with e.g. `sudo apt install g++-10` and then passing `NVCCFLAGS='-ccbin /usr/bin/g++-10'` or equivalent as a Make argument.)
