I took a look at crosstool-0.38/ptx.sh, and tried to figure out how to build my own rootfs that only contained the absolute minumum needed to boot up to a bash shell on an i686 system. I think this covers it: # Build i686 toolchain using crosstool TARBALLS_DIR=$HOME/downloads RESULT_TOP=/tmp/crosstool export TARBALLS_DIR RESULT_TOP export GCC_LANGUAGES="c,c++" mkdir -p $RESULT_TOP eval `cat i686.dat gcc-4.1-20050716-glibc-2.3.2-hdrs-2.6.11.2.dat` sh all.sh --notest --testlinux # Create a rootfs directory and install crosstool's libraries into it export PREFIX=$RESULT_TOP/$GCC_DIR-$GLIBC_DIR/$TARGET export ROOTFS=$PREFIX/rootfs mkdir -p $ROOTFS cd $PREFIX/$TARGET for lib in \ ld libBrokenLocale libSegFault libanl libc libcrypt libdl libgcc_s libgcc_s_nof libm \ libmemusage libnsl libnss_compat libnss_dns libnss_files libnss_hesiod libnss_nis \ libnss_nisplus libpcprofile libpthread libresolv librt libstdc++ libthread_db libutil; do ls lib/$lib[-.]*so* || true ls usr/lib/$lib[-.]*so* || true done 2> /dev/null | cpio -pvm $ROOTFS # Install bash into the rootfs and link it to /linuxrc cd /tmp tar xvjf bash-3.0.tar.bz2 cd bash-3.0 export CC=$PREFIX/bin/$TARGET-gcc export CXX=$PREFIX/bin/$TARGET-g++ export LD=$PREFIX/bin/$TARGET-ld ./configure --prefix=$ROOTFS make make install ln -s bin/bash $ROOTFS/linuxrc Is this really all I need to run cramfs on to generate a rootfs image that I can burn on the target? Will the libraries generated by crosstool suffice as runtime libraries for the target? Will setting CC, CXX, and LD to my cross compiler be sufficient for building a bash that will run on the target?
