Linux for the Casio BE-300

For the latest (unstable !) 2.6.x kernels

I'm currently using the pre-compiled toolchain from ftp://ftp.mips.com/pub/tools/software/sde-for-linux/sdelinux-mipsel-latest.i386.rpm .

You can get a precompiled toolchain (BSP) from TimeSys, after (free) registration:

Trust me, registering is much faster and easier than building your own ;-)

Build your own

If you want to build your own, I strongly suggest to take a look at jal0's pages for detailed instructions.

Below are the outdated instructions to build you own on Linux, based on instructions from Bradley D. LaRonde (http://www.ltc.com/~brad/mips/mipsel-linux-cross-toolchain-building.txt)

If you want to use a Win32 host instead of a linux host, please take a look at jal0's instructions

# Copying the files isn't quite enough though. You also need to edit /usr/local/
# mipsel-linux/lib/libc.so (yes, it is a text file suprisingly enough) to point
# to the cross-built glibc files so that the cross-build tools know to use the
# mipsel libc and not the host's libc, something like:
#
# GROUP ( /usr/local/mipsel-linux/lib/libc.so.6
# /usr/local/mipsel-linux/lib/libc_nonshared.a )

# Build the final C and C++ cross-compilers
cd mipsel-gcc

and that's all ...
