Crosstool is a collection of scripts which can help you building a cross compiler toolchain without pain. Get the latest version from [1]
Build the toolchain
Reciva uses two different toolchains to build the radio software. gcc 3.3.4 is used for the kernel, and 4.1.0 is used for the userspace applications.
We'll create a toolchain with the same versions:
- unpack crosstool:
tar -zxvf crosstool-<version>.tgz
- choose the right flavour and build
export RESULT_TOP=/opt/crosstool eval `cat arm9tdmi.dat gcc-4.1.0-glibc-2.3.2.dat` sh all.sh --notest
This might take some time. If all goes well, you'll and up with a fresh cross complier in /opt/crosstool
