Hi there.  
I was compiling MySQL server sources on OpenSUSE Leap 15.6. I was specifying compilers like this:

> cmake -DCMAKE\_CXX\_COMPILER=g+±16 \_DCMAKE\_C\_COMPILER=gcc-16 -DWITH\_SYSTEM\_LIBS=TRUE ..

Here is what I get:

> – Running cmake version 3.28.3  
> – Found Git: /usr/bin/git (found version “2.43.0”)  
> – CMAKE\_MODULE\_PATH is /home/yantitarenko5/mysql-server/cmake  
> – MySQL 9.3.0  
> – The C compiler identification is GNU 7.5.0  
> – The CXX compiler identification is GNU 16.0.0  
> – Detecting C compiler ABI info  
> – Detecting C compiler ABI info - done  
> – Check for working C compiler: /usr/bin/cc - skipped  
> – Detecting C compile features  
> – Detecting C compile features - done  
> – Detecting CXX compiler ABI info  
> – Detecting CXX compiler ABI info - done  
> – Check for working CXX compiler: /usr/bin/g+±16 - skipped  
> – Detecting CXX compile features  
> – Detecting CXX compile features - done

Please help

There’s a typo in your command line. You have an underscore in `_DCMAKE_C_COMPILER` instead of the expected dash `-DCMAKE_C_COMPILER`
