Indeed this is the error message:

     /usr/lib/gcc/x86_64-linux-gnu/15/include/omp.h:568:1: error: template with C linkage
       568 | template<typename __T>
           | ^~~~~~~~
     rsb_common.h:32:1: note: ‘extern "C"’ linkage started here
        32 | extern "C" {

The omp.h file includes C++ statements (template definitions) but it 
is included inside an 'extern "C" {}' block.

I am sorry I do not know how to fix this.

@Michele: if you can find a way to fix this, I can try it on my forky 
chroot.

Best,
