Those patches are necessary. Otherwise it will fail at many points.

Also, that's an external toolchain and I don't have much information about it :S >> The full build log is here: >> >> http://autobuild.buildroot.net/results/16f/16f6956d5a215fe678a45cc4b24ba= 196309ee05c/build-end.log > = > It looks like that is a fairly old 0.155 build with several patches > applied. Have you tried latest elfutils 0.160 or current git? I have tried elfutils-0.160, but I'm having this error: /br/output/host/usr/bin/mipsel-linux-gcc -D_GNU_SOURCE -DHAVE_CONFIG_H -DLOCALEDIR=3D'"/usr/share/locale"' -I. -I.. -I. -I. -I../lib -I.. -I./../libelf -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -std=3Dgnu99 -Wall -Wshadow -Werror -Wunused -Wextra -fgnu89-inline -Wformat=3D2 -fpic -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -pipe -Os -g2 -static -c -o color.o color.c color.c: In function =E2=80=98parse_opt=E2=80=99: color.c:135:5: error: passing argument 4 of =E2=80=98argp_help=E2=80=99 dis= cards =E2=80=98const=E2=80=99 qualifier from pointer target type [-Werror] program_invocation_short_name); ^ In file included from color.c:34:0: /home/ldap/vriera/work/mips-buildroots/mips32/output/host/usr/mipsel-buildr= oot-linux-uclibc/sysroot/usr/include/argp.h:469:13: note: expected =E2=80=98char *=E2=80=99 but argument is of type =E2=80=98co= nst char *=E2=80=99 extern void argp_help (__const struct argp *__restrict __argp, ^ cc1: all warnings being treated as errors make[3]: *** [color.o] Error 1 > If you think any of those patches are useful could you submit them so we > can review them for inclusion upstream? Please have a look to those patches here.
