search for: nostdlib

16396:055d98aa2dd0 almost works but not quite. LDFLAGS_DIRECT means we end up with: gld -melf_i386 -nostdlib -N -Ttext 0x100000 -o hvmloader.tmp hvmloader.o mp_tables.o util.o smbios.o 32bitbios_support.o acpi/acpi.a Specifying a linker script and asking for -nostdlib is obviously contradictory. Removing $(LDFLAGS_DIRECT) fixes the problem. regards john _______________________________________________ X...
