Hello, I am trying to cross compile boost for an embedded processor that has its own gcc and g++ compiler. What are the options I need to invoke so that the make uses these compilers instead of gcc? Also, can you tell me the simpliest way to test it? Thanks, Esteban

To test what? I do not think that cross-testing is current supported, unless the OS on your host machine is configured to transparently execute target OS binaries. - Volodya

An update... I found the link that tells me how to build Bjam, but I run into a problem on the last part of the script: if test -x "./bootstrap/jam0" ; then if test "${BJAM_UPDATE}" != "update" ; then echo "bjam update = update" # echo_run ./bootstrap/jam0 -f build.jam --toolset=$BOOST_JAM_TOOLSET "--toolset-root=$BOOST_JAM_TOOLSET_ROOT" clean echo_run ./bootstrap/jam0 -f build.jam --toolset=tile "--toolset-root=$BOOST_JAM_TOOLSET_ROOT" clean fi echo "no update, just build" # echo_run ./bootstrap/jam0 -f build.jam --toolset=$BOOST_JAM_TOOLSET "--toolset-root=$BOOST_JAM_TOOLSET_ROOT" "$@" echo_run ./bootstrap/jam0 -f build.jam --toolset=tile "--toolset-root=$BOOST_JAM_TOOLSET_ROOT" "$@" Fi Because I have cross-compiled, I am not able to execute build.jam on the host. However when I try to execute on the target, the compiler is only on the host and the toolset I defined is not recognized! Yes, I copied the entire src directory into the target. _____________________________________________ From: Yepez, Esteban Sent: Thursday, January 29, 2009 11:23 AM To: 'boost-users@lists.boost.org' Subject: Cross compiling Hello, I am trying to cross compile boost for an embedded processor that has its own gcc and g++ compiler.

To build bjam you must use a compiler for the host because bjam has to run on the host. There's no way around this. In Christ, Steven Watanabe
steve- yeah i understand. However, I don't know how to tell the last stage to use my embedded compiler. That is the following command fails: echo_run ./bootstrap/jam0 -f build.jam --toolset=tile "--toolset-root=$BOOST_JAM_TOOLSET_ROOT" clean because it doesn't recognize the toolset=tile. For some reason, the makefile doesn't go back and set the BOOST_JAMCC=tile-gcc ________________________________________ From: boost-users-bounces@lists.boost.org [boost-users-bounces@lists.boost.org] On Behalf Of Steven Watanabe [watanabesj@gmail.com] Sent: Thursday, January 29, 2009 7:35 PM To: boost-users@lists.boost.org Subject: Re: [Boost-users] Cross compiling AMDG Yepez, Esteban wrote:

What "last stage"
That is the following command fails: echo_run ./bootstrap/jam0 -f build.jam --toolset=tile "--toolset-root=$BOOST_JAM_TOOLSET_ROOT" clean

Oh, don't use configure/makefile. First build bjam yourself (for host), then build by directly invoking bjam. - Volodya
the problem is that I don't know how to tell jam to use my embedded compiler when it tries to generate build.jam sh ./build.sh Yes, initially, I had modified the build.sh and set BOOST_JAM_CC=tile-gcc. But like you said, I want to use the host compiler in the first stage and the target compiler to do the last bit.

sh ./build.sh
When building bjam, with "./build.sh", you don't need to use your embedded compiler. bjam is purely host binary, it does not know anything about the compiler that will be used later.
Yes, initially, I had modified the build.sh and set BOOST_JAM_CC=tile-gcc. But like you said, I want to use the host compiler in the first stage
Yes, so you build bjam for the host.
and the target compiler to do the last bit.
So I still get an error because it doesn't pick up the embedded compiler tile-gcc
After you've build bjam for the host, you follow instructions at: http://www.boost.org/boost-build2/doc/html/bbv2/tasks/crosscompile.html which shows both where to specify the compiler command, and how to request that this compiler be used. Did you try those instructions? - Volodya

THESE INSTRUCTIONS TELL YOU TO INDICATE AN ALTERNATIVE TOOLSET. HOW DO YOU CREATE A TOOLSET. THAT IS I WANT IT TO PICK UP A CC THAT IS NOT CURRENTLY SUPPORTED.

Previously, you have said: > I am trying to cross compile boost for an embedded processor that has its own gcc and > g++ compiler. So, it's not a new compiler, it is just gcc. Then, you should do exactly what the doc say: 1. Put this in user-config.jam: using gcc : tile : tile-g++ ; 2. Add this to bjam command line: toolset=gcc-tile - Volodya
