Hello

Here is a more succient attempt at building boost with a cross compiler. It appears to work. I'm not certain if it works at this point though. Please take a look and comment. Here is the script:

---------------------------------------------------------------

#!/bin/bash

# edit /opt/xxx/yyy/boost/boost_1_51_0/tools/build/v2/user-config.jam to add the following line

# using gcc : 4.3arm : arm-linux-gnueabi-g++ : <architecture>arm <target-os>linux ;

# Later we modify path, make sure our path does not use the cross compiler at beginning

export PATH=/usr/local/sbin:/usr/local/bin:/usr/bin:/opt/java6/bin:/opt/java6/db/bin:/opt/java6/jre/bin:/usr/bin/site_perl:/usr/bin/vendor_perl:/usr/bin/core_perl

# In this stage, we are using the host compiler.

# setup env variable for $BOOST_DIR

# I'm not sure if this is being used, but set it just in case.

export BOOST_ROOT=/opt/xxx/yyy/boost/boost_1_51_0

# this is run from $BOOST_DIR/tools/build/v2 aka /opt/xxx/yyy/boost/boost_1_51_0/tools/build/v2

# in this case, I do not think you invoke the cross compiler. I think at this point, you are building

# code for the host development machine.

./bootstrap.sh --with-toolset=gcc

# setup path so that gcc from cross compiler is first in the path

# also specify cross_compiler env variable in case its used.

# this will find the cross compiler for those who dont use the prefix, ie. gcc

export PATH=/opt/arm/usr/local/arm-linux-gnueabi/bin:$PATH

# this will find the cross compiler for those who use the prefix, ie. arm-linux-gnueabi-gcc

export PATH=/opt/arm/usr/local/bin:$PATH

# this will set the cross compiler prefix for those who use it

export CROSS_COMPILE=arm-linux-gnueabi-

# build boost.build so that we can build boost or are we building boost at this point?

# WARNING!!!

# Specify an install directory so that it doesn't put the results in /usr/local/bin.

# Even if you dont specify install as an option to ./b2 it will attempt to copy files to /usr/bin

# in the following step!

# /opt/xxx/boost is where we want results. Our code will this dir in order to use boost.

# /opt/xxx/yyy/boost/boost_1_51_0 is the top of the boost src. We are building beneath there.

./b2 --toolset=gcc-4.3arm --prefix=/opt/xxx/boost

# at this point, we have the cross compiler in our path first. We are good to go for building our code using boost

# with the cross compiler.
