RE:How to make a gcc for MPC860 ?

[沈惠如]

Hi

Firstly, I would like to say thanks to bie.jiuling for his reply to my question
I have not try his patch file yet.
I think it will work well. :)

One thing I would like to share with everyone who try to make a gcc compiler for 860 is :
get "gcc.2.95.2.tar.gz"  not  "gcc.2.95.2.core + gcc.2.95.2.g++" <-- according to  < http://sources.redhat.com/ecos/tools/linux-powerpc-eabi.html >
I check my configure.out, and find that it seems that I miss some files.
So I get lots of error "can't find file xxx"
I try the gcc.2.95.2.tar.gz and follow the steps in the < http://sources.redhat.com/ecos/tools/linux-powerpc-eabi.html >
Thank God, everything works ! :)

good luck to everyone !

Could you help me out or give some advice?
(what kind of flags/files/ENVs should I have?)

I try that the the make process goes fine. My
custom part of "configure" is 

--target=powerpc-eabi
--prefix=/tmp/pun \
--exec-prefix=/tmp/pun/H-i686-pc-linux-gnu \

but I get the following error.

 Some targets are fully defined, some are not. The m68k-*, mips*-* and powerpc-eabi
aren't, so you must use the stuff for some real target board for them.

 You can link programs only for a known target.

How to make a gcc for MPC860 ?

[沈惠如]

Hi

I try to make a gcc comliler for a motorola MPC860 CPU in a Linux host.
I follow every step in http://sources.redhat.com/ecos/tools/linux-powerpc-eabi.html

First, I build the GNU Binary Utilities following the steps list in this web page
note: I have untar the binutils 2.10 to /src/binutils/binutils-2.10 exactly follow the instructions in the web page

mkdir -p /tmp/build/binutils
cd /tmp/build/binutils
/src/binutils/binutils-2.10/configure --target=powerpc-eabi \
--prefix=/tools \
--exec-prefix=/tools/H-i686-pc-linux-gnu \
-v 2>&1 | tee configure.out 

and then

make -w all install 2>&1 | tee make.out 

I think I make it, because there are files produced in 
/tools/H-i686-pc-linux-gnu/
there are three sub directories
bin/ lib/ powerpc-eabi/

Now, I try to make a gcc fot 860

PATH=/tools/H-i686-pc-linux-gnu/bin:$PATH ; export PATH    (for sh, ksh and bash users)
mkdir -p /tmp/build/gcc
cd /tmp/build/gcc
 /src/gcc/gcc-2.95.2/configure --target=powerpc-eabi \
--prefix=/tools \
--exec-prefix=/tools/H-i686-pc-linux-gnu \
--with-gnu-as --with-gnu-ld --with-newlib \
-v 2>&1 | tee configure.out 

>>>>> BUT, the configuration is not end up correctly !!!!!!!!
It end up with an error message:
configuration rs6000-ibm-eabi not supported

So I try to fix this problem by add the option --with-cpu=860

 /src/gcc/gcc-2.95.2/configure --target=powerpc-eabi \
--prefix=/tools \
--exec-prefix=/tools/H-i686-pc-linux-gnu \
--with-gnu-as --with-gnu-ld --with-newlib \
--with-cpu=860 \     <-----------------------------add this
-v 2>&1 | tee configure.out 

the error message " configuration rs6000-ibm-eabi not supported" is gone
But, I still fail
Part of the configure.out are list bellow
