can not crosscompile gcc-2.95.2 with glibc-2.1.3 headers

[douglas]

   Hi

    Thanks for the work around with newlib, I has able to make a cross
compiler for mips, using redhat 6.2 for x86, based on newlib.

The work around for the unistd.h and stdlib.h not found is
   ( Thanks to João for supplying the fix )

 cd <gcc-src-dir>/gcc-2.95.2
 ln -s <newlib-src-dir>/newlib-1.8.2/newlib newlib
 ln -s <newlib-src-dir>/newlib-1.8.2/libgloss libgloss

However I tried to create a crossGCC based on the includes for
glibc-2.1.3, and the linux 2.4.0 kernel includes.  Ouch.



Building the cross binutils is ok.
In directory  build-utl

 ../binutils-2.10/configure --target=mips-linux --prefix=/export/cross2/mips -v

-----------------------------------------------------------------------------------
Then  setup for gcc-2.95.2

     moved crypt and linuxthreads  into glibc-2.1.3/

     in /export/cross2/mips/mips-linux/include
     moved the linux 2.4.0 kernel headers in place
     moved asm-mips inplace
     link  asm-mips -- asm

     PATH=/export/cross2/mips/bin:$PATH export PATH

In directory build-gcc
   ../gcc-2.95.2/configure --target=mips-linux
--prefix=/export/cross2/mips --with-headers=../glibc-2.1.3/include -v


make all LANGUAGES="c"

  Does any one know the work adound for this, or di I take a wrong step
somewhere ?


    Thanks
