Q: (cross)compiling for the Meshcube (fwd)

Q: (cross)compiling for the Meshcube (fwd)

[Ralf Ackermann]

Hello,

I'm trying to (cross)compile some more modules/applications for the 
meshcube - but failed so far.

I installed (on an i386 system):
	binutils-mipsel-linux-2.13.2.1-3.i386.rpm
	gcc-mipsel-linux-2.95.4-1.i386.rpm
(from ftp://ftp.linux-mips.org/pub/linux/mips/crossdev/)

Making a hello world program fails with:
	mipsel-linux-gcc hello.c -o hello
	/usr/mipsel-linux/bin/ld: cannot open crt1.o: No such file or directory
	collect2: ld returned 1 exit status

My questions:
 - Are there any specific hints for the cross-compile environment
	(or: "What are you using ... and would therefore suggest ?)
 - Is there any chance to use a native gcc on the cube itself?
	(could this e.g. been done by chrooting into a (which?)
	existing MIPS Linux distribution that is mounted via NFS)

Any hints are highly appreciated (I have worked with crosscompile/native 
environments for ARM so far, but these are my first experiences in the 
MIPS world).

regards
 Ralf

You don't mention installing libc for the platform. You will need libraries
for the MIPS(el) target to be present in the cross-compile path.
Try ftp://ftp.linux-mips.org/pub/linux/mips/glibc/mipsel-linux/

On doing Native build, if your platform supports tftp loading of boot kernel
(or if it has a boot kernel which you can pass parameter to), load the
kernel with nfsroot="IP-Address-of-server:/path" ip=ip-address-of-target

This requires an NFS image to be kept somewhere reachable by your target.
There is a tarball of RH7.1(mipsel) NFS dump at MIPS ftp for which worked
for my MALTA.

I did (sometime) ago produce NFS image of RH7.3 for my MALTA board. I can
upload it if you can tell me a location where to put it.

Native compiles should work. AFAIK the Meshcube uses a customized
debian, most likely a testing/unstable mix. If you have a debian system
around, you can install the "debootstrap" package there and use it to
create a mips chroot, configure it, export it to the Meshcube, and
install the "build-essential" package there. This gives you the usual
native debian development environment.

hi!

we use crosstool from http://www.kegel.com/crosstool/ to create a cross 
toolchain. it is also part of our build system, we have at 
http://www.meshcube.org/ in the CVS. if you check it out, you can cd into the 
build/ directory and "make toolchain". the cross prefix is then 
mipsel-mtx-linux-gnu-.

greetings,
bruno
