OK, here is more information. I thought it was maybe a common problem, but it seems not
- Copied the file on my SD card and did ./image_setup dev_img-1.5 /mnt/dev
- relogged as zarus
- changed the PATH to make it correct (the install script added something like /home/zaurus/dev/-, but everything was installed in /home/zaurus/develop/-) : export PATH=/usr/bin:/bin:/usr/sbin:/sbin:/home/zaurus/develop/bin:/home/zaurus/develop/usr/local/bin.
I tried to compile libSDL from zports (1.2.6-5). I know I could just copy by hand the headers and the objects I have cross-compiled, but that is not the point here.
$ ./configure
checking build system type... armv5tel-unknown-linux-gnu
checking host system type... armv5tel-unknown-linux-gnu
checking target system type... armv5tel-unknown-linux-gnu
./configure: line 1516: syntax error near unexpected token `AM_INIT_AUTOMAKE(SDL,'
./configure: line 1516: `AM_INIT_AUTOMAKE(SDL, $SDL_VERSION)'
I told myself : just need to rerun autogen.sh for the build informations to adapt to this compiling environment, and I had the problem explained above...
