Can you do a manual make for the tool and header?
I get in that case a:

[agerrits at pc67148960 MPlayer-20030616]$ make codec-cfg
gcc -O4   -pipe -ffast-math -fomit-frame-pointer -Ilibmpdemux -Iloader -Ilib
vo        -g codec-cfg.c mp_msg.c -o codec-cfg -DCODECS2HTML
[agerrits at pc67148960 MPlayer-20030616]$ make codecs.conf.h
./codec-cfg ./etc/codecs.conf > codecs.conf.h

If that succedes it is just that for some reason the main makefile fauls up.
See also the next comment.

By doing a "make codecs.conf.h" you can manually generate this required
I know, this is just a workaround, but it may help you get further.

The files look fine at first sight.

However it still is strange since in my case the 'make' starts with:

[agerrits at pc67148960 MPlayer-20030616]$ make
arm-linux-gcc -c -O4   -pipe -ffast-math -fomit-frame-pointer -Ilibmpdemux -
Iloader -Ilibvo        -o mplayer.o mplayer.c
mplayer.c: In function `main':
mplayer.c:805: warning: passing arg 2 of `m_config_register_options' from
incompatible pointer type
arm-linux-gcc -c -O4   -pipe -ffast-math -fomit-frame-pointer -Ilibmpdemux -
Iloader -Ilibvo        -o mp_msg.o mp_msg.c
arm-linux-gcc -c -O4   -pipe -ffast-math -fomit-frame-pointer -Ilibmpdemux -
Iloader -Ilibvo        -o cpudetect.o cpudetect.c
gcc -O4   -pipe -ffast-math -fomit-frame-pointer -Ilibmpdemux -Iloader -Ilib
vo        -g codec-cfg.c mp_msg.c -o codec-cfg -DCODECS2HTML
./codec-cfg ./etc/codecs.conf > codecs.conf.h
arm-linux-gcc -c -O4   -pipe -ffast-math -fomit-frame-pointer -Ilibmpdemux -
Iloader -Ilibvo        -o codec-cfg.o codec-cfg.c

... and then it continues.

The file looks fine, but there is of course not much you can faul up there.
And it compiles ...
Maybe a stupid question, but other programs created with this compiler work
on iPaq?
Note also that I didn't really like the testtools. I played only a bit with
them. (They didn't crash however on our ARM 920T.)

My info:

arm-linux-gcc --version = 2.95.3

And I used:


Hope this helps a bit.
