your are right, I have to remove the C++ support, below is my config.status
file:
#!/bin/sh
# This file was generated automatically by configure. Do not edit.
# This directory was configured as follows:
../gcc-2.95.2/configure
--with-gcc-version-trigger=/tar-files/gcc-src/gcc-2.95.2/gcc/version.c
--host=i586-pc-linux-gnu --target=a29k-coff --prefix=/sw/newtools
--with-gnu-as --with-gnu-ld --with-newlib --enable-languages=c -v
--norecursion
#
but I got the error msg:
../../gcc-2.95.2/gcc/combine.c:3362: warning: integer overflow in expression
../../gcc-2.95.2/gcc/combine.c:3367: warning: integer overflow in expression
what does this mean ?
thanks in advance
