Typical Error 2 is thrown, if your linker is running out of memory. For building a debug build with 24 threads you need in peak 70GB RAM. I suggest to set manually the number of cores via the argument --number-of-cores.

8GB RAM per thread is safe. 4GB per thread my also work.

my memory is enough, this is the error
