I have built both ALSA-libs and SALSA-libs for my ARM SoC system. However, there are a lot of features I am sure I do not need, e.g. mixer. I would like to build the minimal SALSA system for playing and capturing audio through a PCM interface. The audio is mono, 8k sample rate with no sw audio control, etc. What tags can I add to get the smallest possible SALSA build. Currently I am doing this:
CC=arm-linux-gcc ./configure --target=arm-linux --host=i686-pc-linux-gnu --with-versioned=no --disable-mixer
then
make install DESTDIR=$HOME/Linux_Builds/buildroot/build_arm/root/
But am still getting about a 400k addition to my rootfs. Anyway to make that smaller?
400k? It's definitely too much.
First, disable static library via --disable-static configure option. You need only libsalsa.so.* for running system. The rest, pkgconfig and include files, are needed only for development. Also, install stripped binaries via 'make install-strip'.
On my system, the above will result in 36kB binary.
(BTW, salsa-lib has no versioned symbols, so --with-versioned=no is useless.)
