Ok ... I'm learning :o) (i think)

On my n810 that gives me this:
[user at nokia ~/src/dsp-alsa/trunk/alsa-lib/test]$ make pcm
cc     pcm.c   -o pcm
pcm.c: In function `help':
pcm.c:719: warning: use of cast expressions as lvalues is deprecated
/var/tmp/ccQOAYhr.o: In function `generate_sine':pcm.c:(.text+0x140):
undefined reference to `snd_pcm_format_width'
:pcm.c:(.text+0x160): undefined reference to `snd_pcm_format_width'
:pcm.c:(.text+0x378): undefined reference to `sin'
/var/tmp/ccQOAYhr.o: In function `set_hwparams':pcm.c:(.text+0x5ac):
undefined reference to `snd_pcm_hw_params_any'
:pcm.c:(.text+0x5c4): undefined reference to `snd_strerror'

On my ubuntu system:
john at system76-pc:~/alsa-lib-1.0.23/test$ make pcm
if gcc -DHAVE_CONFIG_H -I. -I. -I../include -I../include   -Wall -pipe
-g -D_GNU_SOURCE -MT pcm.o -MD -MP -MF ".deps/pcm.Tpo" -c -o pcm.o
pcm.c; \
	then mv -f ".deps/pcm.Tpo" ".deps/pcm.Po"; else rm -f
".deps/pcm.Tpo"; exit 1; fi
make: *** No rule to make target `../src/libasound.la', needed by `pcm'.  Stop.

It works on the ubuntu system only if I run 'make check' first, as
mentioned by Clemens Ladisch in another post.

I copied the file .deps/pcm.Tpo from the ubunutu system to the n810,
and pasted the output from the ubuntu command "make pcm" in directly:
[user at nokia ~/src/dsp-alsa/trunk/alsa-lib/test]$ if gcc
-DHAVE_CONFIG_H -I. -I. -I../include -I../include   -Wall -pipe -g
-D_GNU_SOURCE -MT pcm.o -MD -MP -MF ".deps/pcm.Tpo" -c -o pcm.o pcm.c;
then mv -f ".deps/pcm.Tpo" ".deps/pcm.Po"; else rm -f ".deps/pcm.Tpo";
exit 1; fi
pcm.c: In function `help':
pcm.c:719: warning: use of cast expressions as lvalues is deprecated

Now it looks to me like that generated pcm.o on both machines.  What
do I do with pcm.o now?
