Linux version 5.14.12-aragorn-lxtec-ppc (riesebie@aragorn) (Debian clang version 13.0.0-5, GNU ld (GNU Binutils for Debian) 2.37) #1lxtecppc1 Sat Oct 16 20:13:36 CEST 2021
Well, linking witch the GNU linker works. Compiletime 4.5 h.
Compiling completely with gcc the same config needs only 2 h.
Will investigate further when ldd is available.
Thanks in advance
