Problem making GCC cross-compiler for MCORE processor.

[LaPonsey Brian-ra4951]

Sandi,

This is the first time I have heard of the source code for MTC4.6 
being released.  The MCore Tech Center must have dug it out of a 
closet and put it on the web.  Until recently, only the binaries 
were up there.

I can't help you build MTCgnu4.6, but I can help if you want to
build mcore-elf tools from the latest releases of GCC, binutils,
newlib and gdb.

You'll have to get these source distributions from a GNU mirror
and put them in a tree as shown underneath your home directory:

~/src/gcc       <-  gcc-core-3.1.tar.bz2 
~/src/binutils  <-  binutils-2.12.1.tar.bz2 
~/src/newlib    <-  newlib-1.10.0.tar.gz 
~/src/gdb       <-  gdb-5.2.tar.bz2 

Once there, you have to extract them yourself.

$ tar xjvf gcc-core-3.1.tar.bz2
... etc
$ tar xzvf newlib-1.10.0.tar.gz

Here is the script I use to build the compiler tools.  It works on 
both Cygwin and Linux (Mandrake 8.2) for me, but your mileage may 
vary.  If you are also going to build gdb, that source code has to 
be slightly patched first.  Let me know if you are interested.

Cheers,
Brian LaPonsey
