erm. libtool supports cross-building as part of the GNU autotools suite. I must admit to being vague about exactly how it all works, but my understanding is that you want the build arch version of libtool installed so that the build machine can run it at build-time. /usr/bin/libtool is indeed generated for the current i.e 'build' architecture. I suspect Kurt is confused about what M-A: foreign means - it means a build-dep that can be satisfied by a foreign architecture (normally the one you are building stuff on). i.e when building libxaw for armel on an amd64 machine the 'libtool' Build-dep is satisfied by libtool:amd64, which is the version that can run on this machine. That is smart enough to to know to look up lib paths for armel, not amd64. Marking it M-A: foreign in Ubuntu allows a number of packages to build with it. libtool is a build-dep of 730 packages in debian and currently none of these can correctly install their cross-build dependencies. This little M-A: foreign annotation in libtool is one of the notable blockers to multiarch cross-building being useful in wheezy/unstable: http://people.linaro.org/~wookey/buildd/quantal/sbuild-ma/status.html currenlty preventing acl, cyrus-sasl2, libdbusmenu, libindicator, libpciaccess, libpng, libxcb, lua5,tslib, xcb-utils and xft. here's an example of it working: http://people.linaro.org/~wookey/buildd/precise/sbuild-ma/libxaw_2:1.0.9-3ubuntu1-precise-ma-cross-armel-20120403-023809.36275.log ┌──────────────────────────────────────────────────────────────────────────────┐ │ Install cross build-dependencies (apt-get -a) │ └──────────────────────────────────────────────────────────────────────────────┘ Cross-deps: Running apt-get -aarmel build-dep libxaw ... libsm6:armel libtool libunistring0 libuuid1:armel libx11-6 libx11-6:armel ...
