gcc-4.1.0 cross-compile for MIPS

gcc-4.1.0 cross-compile for MIPS

[kernel coder]

hi,
   I'm trying to cross compile gcc-4.1.0 for mipsel platform.Following
is the sequence of commands which i'm using.My host system is i686.

../gcc-4.1.0/configure --target=mipsel --without-headres
--prefix=/home/shahzad/install/ --with-newlib --enable-languages=c

make

But following error is generated

/home/shahzad/mips_gcc/./gcc/xgcc -B/home/shahzad/mips_gcc/./gcc/
-B/home/shahzad/install//mipsel/bin/

I'm using fedora 5 as development platform and version of gcc
installed on system is 4.1.0

I have successfully build a newlib based crosscompiler but it's gcc 4.0.3.

Anyway  I have some notes on your configuration:

--without-headres (is it a typo?)

Instead I have:
--with-headers=<path_to_newlib>/src/newlib/libc/include \

May be this helps.

Ralf

Re: gcc-4.1.0 cross-compile for MIPS

[kernel coder]

thanks ,i did a grep in gcc source directory for fcntl.h but there was
no such file in source code.
I think i should explicitly include path for fcntl.h file.

For gcc-3.4.2 i used following sequence of commands.

binutils
------------
../binutils-2.16.1/configure --prefix=/home/shahzad/install --target=mipsel
make
make install

 gcc-3.4.2
----------------------------
../gcc-3.4.2/configure --prefix=/home/shahzad/install --target=mipsel
--without-headers --with-newlib --enable-languages=c
make
make install

glibc
-----------
../glibc-2.3.1/configure --host=mipsel --prefix="/usr"
--enable-add-ons     -with-headers=/home/shahzad/install/include

make cross-compiling=yes  --prefix="" install-headers

gcc-3.4.2
--------------
../gcc-3.4.2/configure --target=mipsel --prefix=/home/shahzad/install
--disable-shared --with-headers=/home/shahzad/install/include
--with-newlib --enable-languages=c

make
make install

Should i change this sequence for gcc-4.1.0.Can someone give his
sequence of commands for his successfull gcc build for mips.

thanks,
shahzad

Re: gcc-4.1.0 cross-compile for MIPS

[Jonathan Day]

Hi,

Two quick questions in return! :) First, did you use
the patches on the Linux From Scratch website, which
fixes problems with GCC in a MIPS environment?
(Although not using the MIPSEL environment myself, I'm
on a big-endiam system, I learned very quickly that
those patches really are essential.)

The second question is why 4.1.0? 4.1.1 fixes some
nasties, from what I understand, making that the
better of the 4.1.x branch. On the flip-side, 4.0.3 is
the last-known version of GCC that will compile G95
correctly, strongly hinting at remaining issues in
4.1.x that have the potential for generating incorrect
code. (I've not been able to build 4.2.x from SVN for
a while, although it adds some features I would love
to use.)

You can't build target libraries like libssp in a --without-headers
build.  It was luck that this happened to work with earlier gcc
releases, because previously we didn't have C language target libraries
in gcc.  The solution is to do
  make all-gcc
  make install-gcc
instead of just
  make all
  make install

Please see Dan Kegel's crosstools package, which already knows how to do
this.

Re: gcc-4.1.0 cross-compile for MIPS

[kernel coder]

yes you were right.When i did
make all-gcc

It just compiled smoothly.

Now to compile glibc-2.3.6 ,I issued following sequence of commands

../glibc-2.3.6/configure --host=mipsel-linux --prefix="/usr"
--enable-add-ons --with-headers=/home/shahzad/install/mipsel/include

 make cross-compiling=yes
install_root=/home/shahzad/install/mipsel/include  prefix=""
install-headers

But following error was generated

make[1]: Entering directory `/home/shahzad/glibc-2.3.6' { echo
'#include "posix/bits/posix1_lim.h"';            \   echo '#define

I did some search on google,but on most of links "-mabi=32" option was
being used with cross-compiler for mips.
Would you please tell me what is causing the problem.

It failed, because it tries to give mips compiler options to the native
(x86?) compiler, which obviously won't work.  And you got this failure
because you configured glibc wrong.

As always, the answer to this problem can be found in Dan Kegel's
crosstools package, which knows how to correctly configure glibc.  Since
you apparently haven't taken my previous hints, instead of giving you
the answer, I'm just going to point you at the crosstools package, and
ask you to look it up yourself.
