At the risk of being flamed out of existence ..

 

I am trying to build a cross-compiler that goes from a pc running
windows 2000 to an embedded Motorola 68360 processor. I have failed in
so many ways so far that I am about ready to give up.

 

Here are things I have tried:

 

1)       Dos configure/compile .. Did not work . this was expected.

2)       Dos compile using bash shell.. Did not work (out of memory)
this was expected

3)       Cygwin compile . DID not work . this was NOT expected .. I hit
several problems ..

a.       Most recently compile errors with function.c

 

gcc -c -DCROSS_COMPILE -DIN_GCC   -DDONT_HAVE_STDIO -DDONT_HAVE_SETJMP
-Dinhibi

t_libc  -g -O2 -W -Wall -Wwrite-strings -Wstrict-prototypes
-Wmissing-prototypes

 -Wtraditional -pedantic -Wno-long-long  -DHAVE_CONFIG_H    -I. -I. -I.
-I./. -I

./config -I./../include function.c -o function.o

b.       Precious bad option

I have tried various "targets" (m68k-coff, m68k-elf, mcore-elf).  I am
working on getting a linux box going to see if I have any better luck
there  (I don't expect to).

 

So here are my questions/goals:

 

1)       Where is some good upto date documentation (either online or in
book) on how to use the Gnu compiler suite in an embedded system or at
least as a cross-compiler? I need to be able to build the compiler
(hopefully for many different targets) and do all the other fun things
like specifying the memory layout.

2)       If there is not an answer to #1, then can anyone tell me how to
solve the problems I am having above. I have looked (probably in all the
wrong places) and tried to find the information I need to no avail. 

 

Thanks,
