Re: [Ltib] LTIB Shell mode and GStreamer application compile.

[Stuart Hughes]

Hi Giorgio,

Check inside the ltib shell:

LTIB> which gcc
/opt/ltib/usr/spoof/gcc
LTIB> which ld
/opt/ltib/usr/spoof/ld
LTIB> which pkg-config
/opt/ltib/usr/bin/pkg-config

Check that pkg-config gives sensible output (you'll need to adjust
paths, but mine shows:)


LTIB> pkg-config --cflags --libs gstreamer-0.10
-pthread
-I/data/seh/Src/ltib_bsps/sv_test/rootfs/usr/include/gstreamer-0.10
-I/data/seh/Src/ltib_bsps/sv_test/rootfs/usr/include/glib-2.0
-I/data/seh/Src/ltib_bsps/sv_test/rootfs/usr/lib/glib-2.0/include
-I/data/seh/Src/ltib_bsps/sv_test/rootfs/usr/include/libxml2  -pthread
-L/data/seh/Src/ltib_bsps/sv_test/rootfs/usr/lib -lgstreamer-0.10
-lgobject-2.0 -lgmodule-2.0 -ldl -lgthread-2.0 -lrt -lxml2 -lglib-2.0

If all that looks okay, make sure you have no .la files in your rootfs
area, these will break cross compiles.  To do this run a checked:

LTIB> find rootfs -name \*.la

If you still get no clue, then post the actually gcc command line you
get (you've cut that out).

Regards, Stuart
