This repository contains make files for easy cross compile of the ALSA Library for Raspberry Pi and BeagleBone.

PACKAGE_VERSION = 1.1.7The ALSA Library can be compiled in one of two ways:
- Using default compiler options.
- In this case the platform architecture is given by the script:
bin/get_arch.sh
- In this case the platform architecture is given by the script:
- Using fine tuned compiler optimizations for a specific SoC.
- In this case the platform architecture is the same as the SoC name.
- The SOC specific compiler options are stored in the make file:
make/soc.mk
# Edit the Makefile for selecting the desired SOC or for not selecting a SOC at all.
vim Makefile# Raspberry Pi Zero
# Raspberry Pi Zero Wireless
SOC = bcm2835
# Raspberry Pi 2 Model B
SOC = bcm2836
# Raspberry Pi 3 Model B
SOC = bcm2837
# BeagleBone Black
# BeagleBone Black Wireless
# BeagleBone Blue
SOC = am3358The ALSA Library can be compiled in one of two ways:
- Using the native compiler on the local platform.
- This option is automatically selected in case no SoC has been selected.
- Using a cross-compiler on the local platform.
