Unfortunately this doesn't seem to work. ld bails out when linking elf/sln. It can't seem to resolve the _DYNAMIC@pcl in elf_machine_load_address(). We can look into this but presume it is not a deal breaker. ~/BR/host/bin/arc-buildroot-linux-gnu-gcc -nostdlib -nostartfiles *-static* -o ~/BR/build/glibc-2f9a78f208a7/build/elf/sln *-static-pie* ~/BR/build/glibc-2f9a78f208a7/build/csu/rcrt1.o ~/BR/build/glibc-2f9a78f208a7/build/csu/crti.o `~/BR/host/bin/arc-buildroot-linux-gnu-gcc --print-file-name=crtbeginS.o` ~/BR/build/glibc-2f9a78f208a7/build/elf/sln.o ~/BR/build/glibc-2f9a78f208a7/build/elf/static-stubs.o -Wl,--start-group ~/BR/build/glibc-2f9a78f208a7/build/libc.a -lgcc -Wl,--end-group `~/BR/host/bin/arc-buildroot-linux-gnu-gcc --print-file-name=crtendS.o` ~/BR/build/glibc-2f9a78f208a7/build/csu/crtn.o ~/BR/host/lib/gcc/arc-buildroot-linux-gnu/8.2.1/../../../../arc-buildroot-linux-gnu/bin/ld: ~/BR/build/glibc-2f9a78f208a7/build/libc.a(dl-reloc-static-pie.o): in function `elf_machine_load_address': ~/BR/build:/glibc-2f9a78f208a7/elf/../sysdeps/arc/dl-machine.h:115: undefined reference to `_DYNAMIC' ~/BR/host/lib/gcc/arc-buildroot-linux-gnu/8.2.1/../../../../arc-buildroot-linux-gnu/bin/ld: ~/BR/build/glibc-2f9a78f208a7/elf/../sysdeps/arc/dl-machine.h:115: undefined reference to `_DYNAMIC' collect2: error: ld returned 1 exit status _______________________________________________ linux-snps-arc mailing list linux-snps-arc@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-snps-arc
