RE: Ncurses for mips

Hi

Now can run configure successfully. Few of the initial messages spit by
configure are listed below

However the compilation fails with the following message.

Soft-mult-div is one of the flags used my cross-compiler and is required. I
don't know why the cross compiler flags are passed to host compiler gcc. I
suppose all the source file should be compiled using my cross compiler.

What may go wrong ? 

Thanks.

Vivek

The config.log file should show more detail.  I have a much simpler script
for testing djgpp cross-compile, and see I'm using --target there.  You'll
run into trouble by not specifying ---with-build-cc, but I don't think it's
a problem at this point in the script.

For reference, this is what I'm using (but bear in mind that the directory
layout of the cross-compiler is important):

#!/bin/sh
# $Id: cfg-djgpp,v 1.3 2004/01/20 23:32:19 tom Exp $ # configure to
cross-compile ncurses for djgcc # # TODO: can I make it build with gnat?
TARGET=i586-pc-msdosdjgpp
TOOLS=/usr/local/compiler/cross/djgpp

# I should put $TOOLS/bin in the path (as does "with-djgpp"), but that's #
clutter.

# autoconf 2.5x AC_CHECK_TOOL looks for the "$TARGET-" prefix.
# autconf 2.13 does not.
export AR=$TOOLS/bin/$TARGET-ar
export RANLIB=$TOOLS/bin/$TARGET-ranlib
export LD=$TOOLS/bin/$TARGET-ld

# autoconf would not guess this:
export CC=djgcc
export CXX=djgpp

cfg-normal \
         --with-build-cc=gcc \
         --host=$TARGET \
         --target=$TARGET \
         $*
