autoconf usage question

[Povolotsky, Alexander]

Cross-compiling gnu (autoconfed packages) on the "clean" cygwin host system 
recently worked well for me, while using the script (adopted from Kai
Ruottu):

#!/bin/sh
AR=/usr/local/bin/powerpc-linux-ar \
CC=/usr/local/bin/powerpc-linux-gcc-3.3.2 \
CFLAGS=-Os \
CXXFLAGS=-Os \
NM=/usr/local/bin/powerpc-linux-nm \
RANLIB=/usr/local/bin/powerpc-linux-ranlib \
AR_FOR_BUILD=ar \
CC_FOR_BUILD=cc \
GCC_FOR_BUILD=gcc \
NM_FOR_BUILD=nm \
RANLIB_FOR_BUILD=ranlib \
AR_FOR_TARGET=/usr/local/bin/powerpc-linux-ar \
CC_FOR_TARGET=/usr/local/bin/powerpc-linux-gcc-3.3.2 \
GCC_FOR_TARGET=/usr/local/bin/powerpc-linux-gcc-3.3.2 \
CXX_FOR_TARGET=/usr/local/bin/powerpc-linux-g++.exe \
OLDCC=/usr/local/bin/powerpc-linux-gcc-3.3.2 \
NM_FOR_TARGET=/usr/local/bin/powerpc-linux-nm \
RANLIB_FOR_TARGET=/usr/local/bin/powerpc-linux-ranlib \
./configure --host=ppc-linux-gnu
make
# PLEAS NOTE -  THERE IS NO "make install" in this script ! ;-)

However, when I started to do "native" compiling on my "dirty used-to-be
target" ppc system,
(embedded diskless board, actually) running on "vanilla" Linux 2.6.8 (I am
building this system from scratch) 
then I am having the problems I have described originally ("I know it's my
own damn fault" )

Cheers,
Alex

Had a problem in same direction. Deleting the 'config.cache' before 
running ./configure helped. But you may have tried that.

I'm (trying to) use GNU autoconf/automake for cross compiling, but find 
it hard to figure out how to do it... Not much info to find on the net.
I'm closing in, trying to figure out the libraries psrt now, but 
documentation ist to good.. :)
