A new C library needs a > new compiler as well. > > So build GCC (see https://gcc.gnu.org/wiki/InstallingGCC for a starting > point) and add --with-native-system-header-dir=/FaF/glibc/include/ to the > configure options. The option --with-native-system-header-dir=/FaF/glibc/include/ didn't work. Now, the include errors appear while compiling gcc. Below some extract. I am working on SLES 12 SP3 - the system glibc version is 2.22. OK it is 3 years old. I am using the newest glibc version 2.27 only for my project. The question is if I really need the newest version. It makes the whole process only too complicated. -------------------------------------------------------------------------------- In file included from /FaF/glibc/include/errno.h:28:0, from ../../../gcc-7.3.0/libgcc/../gcc/tsystem.h:93, from ../../../gcc-7.3.0/libgcc/libgcc2.c:27: /FaF/glibc/include/bits/errno.h:26:11: fatal error: linux/errno.h: No such file or directory # include <linux/errno.h> ^~~~~~~~~~~~~~~ In file included from /FaF/glibc/include/errno.h:28:0, from ../../../gcc-7.3.0/libgcc/../gcc/tsystem.h:93, from ../../../gcc-7.3.0/libgcc/libgcov.h:42, from ../../../gcc-7.3.0/libgcc/libgcov-interface.c:26: /FaF/glibc/include/bits/errno.h:26:11: fatal error: linux/errno.h: No such file or directory # include <linux/errno.h> ^~~~~~~~~~~~~~~ In file included from /FaF/glibc/include/errno.h:28:0, from ../../../gcc-7.3.0/libgcc/../gcc/tsystem.h:93, from ../../../gcc-7.3.0/libgcc/libgcov.h:42, from ../../../gcc-7.3.0/libgcc/libgcov-merge.c:26:
