Re: [alsa-devel] How to cross compile the alsa ?
Yeah, I configure with --enable-static=yes and another parameter :
#CC=arm-gp2x-linux ./configure –host=i686.linux –target=arm-gp2x-linux –enable-store=no –enable-static=yes
And same make and make install... But when I copy all files in corresponding directory on /usr/arm-gp2x-linux/usr/* after then I compile.
But I look errors that not defined reference, I don't undertand, What I do bad?

You look this file jpeg that I send us
You forgot the wooden table: http://thedailywtf.com/Articles/Web_0_0x2e_1.aspx
#arm-gp2x-linux -static -lasound -o micro micro.c
You have to add all the other libraries that libasound depends on, such as libdl and libpthread.

Ok, I've all files, but to be continued fail and I don't know why can't send new posts in forum alsa-devel

Hi again,
Another question, how I can get the volume of the microphone real= dynamic? I like getting volume of the micro, to change volume of speakers.
I don't know if I will explain .

Hi Clemens and friends,
I've some problem referents with alsa and get volume from mircophone:
1.- When to compile the file ,returned these lines.Could be problem to keep?

2.- The previous to say, despite being a warning can create executable file. But when return:

I'm sorpress because not exist this file, but the route /usr/share/ has others folders differents of alsa, Does it change the route?

warning: Using 'dlopen' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking
This message means exactly what it says.

So you didn't copy this directory to the target system? (With the earlier install command, it would be at /tmp/blah/usr/share/alsa.)
Please note that _all_ files installed by 'make install' are needed for either compiling/linking or at runtime.
Regards, Clemens
Thanks Clemens, no problem .
But not affect this warning? It can affect how can to fix it? And you know how I can get the volume that enters the microphone at the time?

Unless you're trying to use a plugin not in alsa-lib.

Don't compile statically.
And you know how I can get the volume that enters the microphone at the time?
The volume of the mixer control or the volume of the audio signal?
Regards, Clemens
Ok!, I'm trying to use another ,with library <sys/soundcard.h> and until question that you ask .I think need to the volume of the audio signal.
Because the audio gets to a microphone and I need to get this volume. I don't know very explain :)
