Alsa library for the arm-linux architecture

Alsa library for the arm-linux architecture

[Felipe Uderman]

Hello,

I need to cross compile a project to the arm-linux platform that depends on
the Alsa Library. My problem is that my cross development environment does
not include the Alsa Library. I have downloaded the Alsa sources, and I
checked that there are some instructions on how to port the library to other
architectures. I would like to know if there are ports of the Alsa Library
for the arm-linux architecture availible for download, or if I really have
to cross compile it.

Thank you for your help!

Felipe

Hi Filipe,
We cross compile alsa-lib 1.0.11rc2 for ARM with:

./configure --prefix=/usr --host=arm-linux --build=i686-pc-linux-gnu
make
make install DESTDIR=/target/root/dir

There was only one patch we had to make, which was to remove the line 
'add_dir="-L$libdir"' (around line 2422) in alsa-lib-1.0.11rc2/ltmain.sh.

You should have a look at BR2 (http://buildroot.uclibc.org/) which  
cross-compiles 1.0.14a for you, most probably also newer versions  
with minor modifications to the appropriate .mk file.

Thanks for the suggestion.  We use a different cross build environment 
called LTIB (http://bitshrine.org).  The patches and build steps are in 
a .spec file like rpm and all enabled packages are built as part of the 
file system.  Building alsa can be done separately with: 'ltib -p alsa-lib'.
