Follow-up Comment #2, bug #34539 (project grub): i think the latest comment contains typos. gold will use the wrong address if you specify "-Wl,-Ttext,8200" (namely, it'll use 0x2008 and not 0x8200). it will work fine if you prefix the address with a hex value like "-Wl,-Ttext,0x8200".
$ gcc -o 1.img -ffreestanding -Wl,-Ttext,8200 1.S -nostdlib -m32 $ readelf -S 1.img | grep text [ 1] .text PROGBITS 00002008 001008 000000 00 AX 0 0 4 $ gcc -o 1.img -ffreestanding -Wl,-Ttext,0x8200 1.S -nostdlib -m32 $ readelf -S 1.img | grep text [ 1] .text PROGBITS 00008200 000200 000000 00 AX 0 0 4 upstream bug: http://sourceware.org/bugzilla/show_bug.cgi?id=14187 it's trivial to workaround in grub2: add a 0x prefix to addresses with the -Ttext flag. a quick grep shows at least: configure.ac: CFLAGS="$TARGET_CFLAGS -nostdlib ${TARGET_IMG_LDFLAGS_AC} ${TARGET_IMG_BASE_LDOPT},8000 -Wl,--defsym,___main=0x8100" _______________________________________________________ Reply to this item at: <http://savannah.gnu.org/bugs/?34539> _______________________________________________ Message sent via/by Savannah http://savannah.gnu.org/ _______________________________________________ Bug-grub mailing list Bug-grub@gnu.org https://lists.gnu.org/mailman/listinfo/bug-grub
