Notice that I relinked pcm dynamically to make it run.
However:
tba:/usr/local/src/alsa-lib-0.9.8/test/ $ make pcm
source='pcm.c' object='pcm.o' libtool=no \
depfile='.deps/pcm.Po' tmpdepfile='.deps/pcm.TPo' \
depmode=gcc /bin/sh ../depcomp \
gcc -DHAVE_CONFIG_H -I. -I. -I../include -I../include -static -Wall -pipe -g -c
`test -f pcm.c || echo './'`pcm.c
/bin/sh ../libtool --mode=link gcc -static -Wall -pipe -g -o pcm pcm.o
../src/libasound.la
mkdir .libs
gcc -Wall -pipe -g -o pcm pcm.o ../src/.libs/libasound.a -lm -ldl -lpthread
tba:/usr/local/src/alsa-lib-0.9.8/test/ $ ./pcm
Playback device is plughw:0,0
Stream parameters are 44100Hz, S16_LE, 1 channels
Sine wave rate is 440.0000Hz
Using transfer method: write
device='plughw:0,0', stream=0, open_mode=0
ALSA lib pcm.c:1876:(snd_pcm_open_conf) symbol _snd_pcm_plug_open is not defined
inside (null)
Playback open error: No such device or address
I added the fprintf("device=...") to the code.
$ libtool --version
ltmain.sh (GNU libtool) 1.5.0a (1.1220.2.35 2003/11/12 18:51:58) Debian: 179 $
Notice that I'm compiling Debian Sid sources, don't run
these myself:
Makefile.in # Makefile.in generated automatically by automake 1.5 from Makefile.am.
$ automake --version
automake (GNU automake) 1.6.3
configure: # Generated by Autoconf 2.52.
$ autoconf --version
autoconf (GNU Autoconf) 2.59
As a side question, should these "ALSA lib..." error
messages be reported from every application which links to
Alsa? Or must they be enabled or similar? I'm struggling
with Glame, in which snd_pcm_open returns Illegal arguments
in a similary trivial call, but I can't see ALSA lib
messages in the output.
