Hi Yann E. MORIN and All, Sorry for the wrong patch. I need to add these line into scripts/crosstool-NG to avoid the wrong choice for compiler. If not, the script would call the Xcode gcc by default. and it cause the target compiler crash at runtime. case "${CT_TOOLCHAIN_TYPE}" in cross) # A cross-compiler runs on the same machine it is built on CT_HOST="${CT_BUILD}" CT_HOST_PREFIX="${CT_BUILD_PREFIX}" // i add CT_HOST_SUFFIX="${CT_BUILD_SUFFIX}" // i add build_mangle="build_" host_mangle="build_" target_mangle="" install_build_tools_for="BUILD HOST" ;; canadian) build_mangle="build_" host_mangle="host_" target_mangle="" install_build_tools_for="BUILD HOST TARGET" ;; *) CT_Abort "No code for '${CT_TOOLCHAIN_TYPE}' toolchain type!" ;; esac Another problem is to build the gdb in static way(script/build/debug/300-gdb.sh). Please refer here if it make sense to you, if [ "${CT_GDB_CROSS}" = "y" ]; then local -a cross_extra_config local gcc_version CT_DoStep INFO "Installing cross-gdb" CT_DoLog EXTRA "Configuring cross-gdb" mkdir -p "${CT_BUILD_DIR}/build-gdb-cross" cd "${CT_BUILD_DIR}/build-gdb-cross" cross_extra_config=("${extra_config[@]}") case "${CT_THREADS}" in none) cross_extra_config+=("--disable-threads");; *) cross_extra_config+=("--enable-threads");; esac CC_for_gdb= LD_for_gdb= if [ "${CT_GDB_CROSS_STATIC}" = "y" ]; then CC_for_gdb="gcc -static" // should we use "${CT_HOST}-gcc static" to replace here? LD_for_gdb="ld -static" // should we use "${CT_HOST}-ld -static" to replace here? fi 在 2011-10-11,上午4:47, Yann E.
