You must force compilation in test directory, for example:
cd alsa-lib/test make pcm
JaroslavOk ... I'm learning :o) (i think)
On my n810 that gives me this: [user@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@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@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?
Trying again ... This time, checking out https://vcs.maemo.org/svn/dsp-alsa and trying to compile pcm.c without 'building' first:
