Hi,
When NLS is disabled or not supported, the macro ENABLE_NLS is not
defined, and this breaks compilation of GRUB modules as they are
compiled with -Werror -Wundef by default. This is with bazaar trunk.
$ ./autogen.sh && ./configure && gmake
[...]
gcc -Ikern -I./kern -nostdinc -isystem /usr/include -I./include -I.
-I./include -Wall -W -Os -DGRUB_MACHINE_PCBIOS=1 -Wall -W -Wshadow
-Wpointer-arith -Wmissing-prototypes -Wundef
-Wstrict-prototypes -g -falign-jumps=1 -falign-loops=1
-falign-functions=1 -mno-mmx -mno-sse -mno-sse2 -mno-3dnow -m32
-fno-stack-protector -mno-stack-arg-probe -Werror -fno-builtin -mrtd
-mregparm=3 -m32 -MD -c -o kernel_img-kern_err.o kern/err.c
In file included from kern/err.c:23:
./include/grub/i18n.h:29:5: error: "ENABLE_NLS" is not defined
gmake: *** [kernel_img-kern_err.o] Error 1
A possible fix consists in replacing the #if ENABLE_NLS by #if
defined(ENABLE_NLS). There are not many instances, so they can be
changed manually, but the following command did the trick for me
(assuming sed is GNU sed):
find . -name '*.[ch]' -exec sed -i -e 's, ENABLE_NLS,
defined(ENABLE_NLS),g' '{}' ';'
Best,
Grégoire
