alsa-lib与alsa-utils都编译成功了,传到开发板上(2440)运行,提示lllegal instruction,在./configure时加上--enable-static 也不行,这个是不是静态编译选项?我是初学的..下面是我的configure

alsa-lib:
./configure --host=arm-none-linux-gnueabi --prefix=/usr/share/arm-alsa --enable-static --disable-python

alsa-utils:
./configure --host=arm-none-linux-gnueabi --prefix=/usr/share/arm-alsa --enable-static --with-alsa-inc-prefix=/usr/share/arm-alsa/include --with-alsa-prefix=/usr/share/arm-alsa/lib --disable-alsamixer --disable-xmlto

编译完后把arm-alsa这个文件夹传到开发板的/usr/share上,运行bin目录下的./aplay出现提示lllegal instruction.
高手们帮帮我吧..谢了.

顶上去...
都来看看啊...

你可能需要在调用alsa-lib和alsa-utils的configure时加上CFLAGS="-march=armv4t", 比如
CFLAGS="-march=armv4t" ./configure --host=arm-none-linux-gnueabi --prefix=/usr/share/arm-alsa --enable-static --disable-python.

你所用的arm-none-linux-gnueabi-gcc默认生成的ARM指令集可能是armv5或更新版本的，不适用于armv4架构的S3C2440A。希望以前的老帖对你有帮助http://www.aiothome.net/read.php?tid-4218.html

我把这句CFLAGS="-march=armv4t"加上了，结果也是一样lllegal instruction.
用file打印aplay的信息：
aplay: ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.14, not stripped

网上有说要把程序编译成静态的才不会出现lllegal instruction？？

终于不提示lllegal instruction了,原来我没有把alsa里的lib复制到开发板的lib目录,但是又有新提示了,
ALSA lib confmisc.c:768:(parse_card) cannot find card '0'

没有找到声卡??我在内核选项里已经把ALSA的一些选项选上了,有没有高手遇过这个??

晕,上面那个也解决了!
现在又有一个提示,我想差不多能播了,解决后把全部过程呈了,

[root@FriendlyARM bin]# ./aplay 11.wav
Playing WAVE '11.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono
aplay: set_params:1059: Channels count non available

最后这句有人见过吗?什么不提供通道?是不是被占用了?

楼主 我也碰上了

和您一样的问题，我看您的留言说您已经解决了。能告诉您是怎么处理的吗

检查/dev下有没有snd这个目录,没有就建一个,然后把/dev下的controlC0,dsp,seq,pcmC0D0c,pcmC0D0p,mixer,timer复制到/dev/snd下

好的我试一试，谢谢！！

你可以换个wav文件是一下，双声道的！
