[GRASS5] Script to build babyGRASS for handhelds

[Markus Neteler]

So,

meanwhile the precompiled iPAQ binaries are installed.
Unfortunately we face a segmentation fault everywhere.
E.g. the Init.sh calls $ETC/set_data:

strace /tmp/dist.armv4l-unknown-linux-gnu/etc/set_data
[...]
open("/tmp/dist.armv4l-unknown-linux-gnu/lib/libgrass_datetime.so",

Looking at the dependencies:
ldd /tmp/dist.armv4l-unknown-linux-gnu/etc/set_data

 /tmp/dist.armv4l-unknown-linux-gnu/etc/set_data:
libgrass_edit.so =>
 /tmp/dist.armv4l-unknown-linux-gnu/lib/libgrass_edit.so (0x4001f000)

libncurses.so.5 => /lib/libncurses.so.5 (0x400c3000)

/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)

... all libs found.

The same with modules:

strace /tmp/dist.armv4l-unknown-linux-gnu/etc/bin/cmd/g.gisenv 
[...]
open("/tmp/dist.armv4l-unknown-linux-gnu/lib/libgrass_datetime.so",

mprotect(0x4001f000, 286720, PROT_READ|PROT_EXEC) = 0
Segmentation fault

I am a bit in the dark here - do we have to install 'gdb' on iPAQ?
The system is:
uname -a
Linux familiar 2.4.16-rmk1 #5 Thu Jan 31 12:06:57 EST 2002 armv4l unknown

Carl, any ideas?

Thanks!

 Markus
