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 in /opt.
- First check that you have flex and bison as they are required but the toolchain builder doesn't check for them.
- unpack crosstool into /opt and rename it. (You will probably need to be root to do this):
cd /opt tar -zxvf crosstool-<version>.tgz mv crosstool-<version> crosstool
- The crosstool builder won't run if you are root but normal users can't write to /opt so set the permissions on the crosstool directory.
chown -R <normal-user> crosstool
- Log in as a normal user and go to /opt
- 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
