All m68k-atari-mint stuff (includes, libraries, config scripts) must be installed in the m68k-atari-mint subdirectory. > My problem is: where do I have to put the mintlib files for a proper > cross-compiler installation? If you have the mintlib-devel-0.57.4 archive, move the contents of the mintlib-devel/usr/lib directory to m68k-atari-mint/lib and the mintlib-devel/usr/include directory to m68k-atari-mint/include > And in the future: How should I compile applications?

To compile GNU applications using configure, I usually run this script: --8<--8<--8<--8<-- cut here, cross-configure.sh #!/bin/sh TARGET=m68k-atari-mint HOST=`gcc -dumpmachine` PREFIX=/home/patrice/local export PATH=${PREFIX}/bin:${PREFIX}/${TARGET}/bin:$PATH export CFLAGS="-m68020-60 -O2 -fomit-frame-pointer" export CXXFLAGS=$CFLAGS export CC=${TARGET}-gcc export CXX=${TARGET}-g++ export RANLIB=${TARGET}-ranlib export AR=${TARGET}-ar export NM=${TARGET}-nm export LD=${TARGET}-ld export STRIP=${TARGET}-strip ./configure \ --prefix=${PREFIX}/${TARGET} \ --host=${HOST} \ --target=${TARGET} \ $* --8<--8<--8<--8<-- cut here Using host and target with different values tells configure it will cross-compile. When configuration is done, I make with this script: --8<--8<--8<--8<-- cut here, cross-make.sh #!/bin/sh MY_TARGET=m68k-atari-mint MY_CROSSPATH=/home/patrice/local export PATH=${MY_CROSSPATH}/bin:${MY_CROSSPATH}/${MY_TARGET}/bin:$PATH make $* --8<--8<--8<--8<-- cut here -- Patrice Mandin WWW: http://membres.lycos.fr/pmandin/ Programmeur Linux, Atari Spécialité: Développement, jeux
