%general-entities; ]> uClibc cross tools Since we are cross-compiling, we need to make sure when we configuration for our architecture we get the correct information. The following sed makes sure we are using the proper settings for our architecture: (This is a place holder for the other architectures cp extra/Configs/Config.in extra/Configs/Config.in.orig sed -e "s:default TARGET_i386:default TARGET_i386:" \ extra/Configs/Config.in.orig > extra/Configs/Config.in Below we are just telling uClibc to use the default configuration of uClibc. For those for more adventureous, you can use make menuconfig, and do a more custom build of your uClibc. Create default configuration: make defconfig We will need to edit the configuration file, to make sure everything gets compiled and put into it's proper locations: cp .config .config.orig sed -e "/^CROSS_COMPILER_PREFIX/s:=.*:=\"${CLFS_TARGET}-\":" \ -e "/^KERNEL_SOURCE/s:=.*:=\"${CLFS}/usr\":" \ -e "/^SHARED_LIB_LOADER_PREFIX/s:=.*:=\"/lib\":" \ -e "/^DEVEL_PREFIX/s:=.*:=\"/usr\":" \ -e "/^RUNTIME_PREFIX/s:=.*:=\"/\":" \ .config.orig > .config We will need to make sure that some settings in uClibc are set so we can utilize all the features of BusyBox: UCLIBC_OPTIONS="DO_C99_MATH UCLIBC_HAS_RPC UCLIBC_HAS_CTYPE_CHECKED UCLIBC_HAS_WCHAR UCLIBC_HAS_HEXADECIMAL_FLOATS UCLIBC_HAS_FOPEN_EXCLUSIVE_MODE UCLIBC_HAS_PRINTF_M_SPEC UCLIBC_HAS_FTW UCLIBC_HAS_IPV6" for config in $UCLIBC_OPTIONS; do cp .config .config.orig sed -e "s:# ${config} is not set:${config}=y:" .config.orig > .config done echo "UCLIBC_HAS_FULL_RPC=y" >> .config Compile the package: make TARGET_ARCH=i386 We will remove the files that were copied over from our Linux Headers, these files were copied into the source directory of uClibc: rm include/{asm,asm-generic,linux} Install the package: make PREFIX=${CLFS} install Installed uClibc To Be Written
