1. 设置正确的架构并重新配置
bash
# 设置正确的架构
export ARCH=i386# 清理配置并重新开始
rm -f .config
make mrpropermake ARCH=i386 defconfig \HOSTCC="/opt/gcc-3.4.6/bin/gcc -m32 -B/opt/gcc-3.4.6/bin/ -L/opt/gcc-3.4.6/lib" \HOSTLD="/opt/gcc-3.4.6/bin/ld" \HOSTCFLAGS="-m32 -static" \HOSTLDFLAGS="-m32 -static"
2. 启用必要的依赖选项
bash
# 确保这些基础选项都启用
echo "CONFIG_DEBUG_KERNEL=y" >> .config
echo "CONFIG_DEBUG_INFO=y" >> .config
echo "CONFIG_MAGIC_SYSRQ=y" >> .config
echo "CONFIG_KALLSYMS=y" >> .config
echo "CONFIG_KALLSYMS_ALL=y" >> .config
3. 启用 KDB 选项
bash
# 启用 KDB
echo "CONFIG_KDB=y" >> .config
echo "CONFIG_KDB_MODULES=y" >> .config
echo "CONFIG_KDB_OFF=y" >> .config
4. 更新配置
bash
# 更新配置，在提示时，对于新选项直接按回车使用默认值
make ARCH=i386 oldconfig \HOSTCC="/opt/gcc-3.4.6/bin/gcc -m32 -B/opt/gcc-3.4.6/bin/ -L/opt/gcc-3.4.6/lib" \HOSTLD="/opt/gcc-3.4.6/bin/ld" \HOSTCFLAGS="-m32 -static" \HOSTLDFLAGS="-m32 -static"检查grep -i "kdb" .config
