How to build ALSA device library onto a board similar to Beaglebone Black?

Hi,

I have downloaded ALSA lib (the latest stable release) from:

ftp://ftp.alsa-project.org/pub/lib/

There is a thread on install ALSA:
http://mailman.alsa-project.org/pipermail/alsa-devel/2011-February/036595.html

Hello alls:
Please help.
I also cross compiled alsa utils trhough CodeSourcery:

PATH=$PATH:/opt/arm-2007q1/bin
CC=arm-none-linux-gnueabi-gcc ./configure --host=i686-pc-linux-gnu \
      --target=arm-none-linux-gnueabi \
      --with-alsa-prefix=/usr/lib \
      --with-alsa-inc-prefix=/usr/include/alsa

After modifying the above command with the difference of my computer:

$ PATH=$PATH:/home/uj/ti-processor-sdk-linux-am335x-evm-01.00.00.03/linux-devkit/sysroots/i686-arago-linux/usr/bin
uj@uj-MS:~/ti-processor-sdk-linux-am335x-evm-01.00.00.03/linux-devkit/alsa-lib$ CC=arm-linux-gnueabihf-gcc ./configure --host=i686-pc-linux-gnu \

It has the fatal error. Could you help on spotting what is the problem on the library building on my Sitara SK board (similar to Beaglebone Black)?

Thanks,

Kinda seems obvious....

Fatal error: Cross-compiling isn't supported...

"Cross-compiling isn't supported..."....

I guess you need to build on the platform. :wink:

Or find a cross-compile patch for alsa...
