1.交叉工具链
下载地址：
http://ci.openharmony.cn/workbench/cicd/dailybuild/dailylist
进入ohos-sdk-full，下载一个sdk版本，这里下载的版本是version-Master_Version-OpenHarmony_5.0.0.35-20240805_020232-ohos-sdk-full.tar.gz。
解压
tar -xf version-Master_Version-OpenHarmony_5.0.0.35-20240805_020232-ohos-sdk-full.tar.gz
cd ohos-sdk
cd linux
unzip native-linux-x64-5.0.0.37-Canary2.zip -d /home/ufo/arm/rk/openharmony/tools/native-5.0配置环境变量
export OHOS_SDK=/home/ufo/arm/rk/openharmony/tools/native-5.0 # 此处是我的ohos_sdk解压目录，请替换为你自己的解压目录
export AR=${OHOS_SDK}/llvm/bin/llvm-ar
export AS=${OHOS_SDK}/llvm/bin/llvm-as
export LD=${OHOS_SDK}/llvm/bin/ld.lld
export RANLIB=${OHOS_SDK}/llvm/bin/llvm-ranlib
export STRIP=${OHOS_SDK}/llvm/bin/llvm-strip
export CC=${OHOS_SDK}/llvm/bin/clang
export CXX=${OHOS_SDK}/llvm/bin/clang++
export NM=${OHOS_SDK}/llvm/bin/llvm-nm
export OBJDUMP=${OHOS_SDK}/llvm/bin/llvm-objdump
export OBJCOPY=${OHOS_SDK}/llvm/bin/llvm-objcopy
export CFLAGS="-fPIC -D__MUSL__=1 --target=aarch64-linux-ohos"
export CXXFLAGS="-fPIC -D__MUSL__=1 --target=aarch64-linux-ohos"使用过其他版本的native，例如version-Master_Version-OpenHarmony_4.0.10.5-20230824_120941-ohos-sdk-full_monthly.tar.gz，但是编译出来的bash程序运行有问题，会报Signal 11错误。
2.下载bash源码
Index of /gnu/bash
版本使用bash-5.2.32
3.交叉编译bash源码
tar -xf bash-5.2.32.tar.gz
cd bash-5.2.32
./configure --prefix=${PWD}/_install --host=aarch64-linux --target=aarch64-linux-ohos --enable-static-link --enable-history --without-bash-malloc
make -j$(nproc)
make install编译成功后在bash-5.2.32源码的_install/bin目录下生成可以执行文件bash。
4.测试
把bash-5.2.32源码下的_install/bin/bash文件复制到板卡
hdc shell mount -o rw,remount /
hdc file send Z:\bash /bin/
hdc shell chmod +x /bin/bash执行测试
hdc shell
#
# bash
bash-5.2#
)
