There are few questions Haomiao,
Is it must to install alsa and PJSIP in /usr/local---Please
share ur requirement.
By default PJSIP looks for alsa file in /usr/include/alsa which
is where alsa headers are installed by default.
In case ur requirement is to install the alsa at some other
place try compiling PJSIP using switch
--includedir=DIR C header files [PREFIX/include]
If this is a requirement you might have to create a soft link
for libasound .so in later stage once your header compilation starts working
where DIR is a location where your alsa header are installed.
Thanks and Regards,
Gaurav

Subject: pjsip configure can't find ALSA headers (cross-compile)
Hi, I'm trying to cross-compile pjsip for arm linux with ALSA and it can't
find the ALSA headers.
it cannot find alsa and I get the following:
checking alsa/version.h usability... no
checking alsa/version.h presence... no
checking for alsa/version.h... no
Asks:
Does anyone know where pjsip looks for the ALSA headers when
cross-compiling? Or does anyone know how to force pjsip to look in a
particular place for ALSA?
Has anyone successfully compiled pjsip for arm with ALSA and would they be
willing to share what they did with me?
I've cross-compiled the alsa library successfully and installed it to
$HOME/arm-install using the commands
$ ./configure --host=arm-none-linux-gnueabi --prefix=/usr/local
$ make
$ make install DESTDIR=/PATH/TO/ARM/BUILD/arm-install
I configure pjsip with
$ ./configure --host=arm-none-linux-gnueabi
--prefix=/PATH/TO/ARM/BUILD/arm-install
Note that I've tried this using --prefix=/usr/local for both, and tried
copying the alsa headers into /usr/local/include, to no effect.
I've also tried to follow the instructions here:
http://theo.cc/blog/2012/04/compile-pjsip-and-pjsua-voip-client-for-the-kind
le-3/
but pjsip still can't find alsa. If only I could figure out where it's
looking, or force it to look in the arm-install directory...
Thanks!
