Hi All,
we want to use alsa library for arm platform.
while configuration we specified option for shared library.
but its alwaye creating static library after compilation.
when we build the test application pcm_min.c we got the
following error.

we tried with the following releases-
1)alsa-lib-1.0.14
2) alsa-lib-1.0.14a
3)alsa-lib-1.0.14rc4
But when we tried to build alsa shared library for x68 platform we did not
face
this problem , but when we built the alsa static library for x86 and tried
to compile the
test application we face the above "undefine reference " error.
Can any one help me to understand and solve this problem?
Thank you
