building crossgcc for m68k-coff on WINNT

building crossgcc for m68k-coff on WINNT

[ron tal]

Hi all,

I have used Enrico' s script (with minor changes) and was able

to deliver a gcc cross compiler m68k-coff under solaris_sparc_2.6

thanx for Enrico, and the rest of the people who have help me so far.



I am trying to do the same (m68k-coff under WINNT), using the same

script. -- I dont see any reason not to.


First, my directory is:

/home/users/ronenl/gcc-cross/
                              binutils-2.10/ unpacked
                              gdb-5.0/ unpacked
                              gcc-2.95.2/ unpacked
                              newlib-1.8.2/ unpacked

                              buildcross.sh <--script


changes I have made:
#!/bin/bash.exe
machine=pentiumpro     - otherwise, I get INVALID i686-pc-cygwin
--host=$machine

Results: binutils-2.10 - successfull
         gcc-2.95.2    - failed (libtool command not found)


Q: is my change for --host=pentiumpro is legal?

Q: how come I pass the binutils, but failed with gcc?

ronen.

Hello,

Could you give us some more information???

- What is your O.S. version (and Service Pack)?
- What is your cygwin version?
- What is your PC processor?
- Are you trying to force the host system as i686-pc-cygwin or the configure
script is matching it for you?


After that, maybe we can try some options...

Try "machine=i586-pc-cygwin"

Try

../$gccdir/configure --host=$machine --target=$target --prefix=$prefix
--with-newlib -v 2>&1 | tee configure.out
make all install 2>&1 | tee make.out

and take a look at configure.out file and make.out file. Maybe you can find in
those files some tips about what is wrong.



Try to update your system to latest cygwin version (1.1.4). This new version has
been improved in many points and many bugs were fixed...


If you can, also try to apply Service Pack 6 on WinNT 4.


Good Luck...

building crossgcc for m68k-coff on WINNT

[ron tal]

hi,

I have successfully install cygwin on my WIN-NT machine.(pentium )

Next, I have unpacked : binutils-2.10  newlib-1.8.2 gcc-2.95.2


Next, I have to configure binutils - this is where I stuck.


The Error message: Invalid  machine i686-pc-cygwin


the command I am using:

configure --target=m68k-coff --prefix=$prefix


I have searched and found: file bashbug contains the machine

type default to be i686-pc-cygwin.


My Q: It seems that the binutils dont recognize i686-pc-cygwin

in its configuration process.  I believe that the machine type

should be one of the types in the configure file.

Then, if we follow this rule, I have not seen anything that

includes cygwin.

Therefore, I will have ToDO: --host=machine_type

My question for you would be - which type should I pick for pentium

machine?

thanx, ronen.

building crossgcc for m68k-coff on WINNT

[ron tal]

I have downloaded cygwin on winnt computer

My goal is to configure/build/install gcc cross compiler for

target M68k-coff on WINNT.

For this purpose I downloaded cygwin, and now I have the

unix-like shell to run the configure script.

The command I am executing :

../binutils-2.9.1/configure --verbose --target=m68k-coff
--prefix=/gcc-68k


and the result:

Invalid Configuration 'i686-pc-cygwin32' : machine 'i686-pc-cygwin32'
is not recognized.

Then, I assume I have ToDo:

--host= ???

My Question: would that solve my problem? if so, what host type

should I use if my HOST is pentium machine.


thanx, ronen.

Maybe i686-pc-cygwin.

But I'd rather start with a newer binutils.  2.9.1 is *very* old.
