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.

The following creates the 4.1.0 toolchain

• 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
