前言
当前lycium上面支持armv7-a和armv8-a的构建,其他架构的构建也是类似的,在HPKBUILD文件中,需要判断架构的地方加上架构相关的信息,这里以新增x86_64架构举例,cmake,makefile, configure构建方式如何修改。
一、构建框架层增加对x86_64的支持
- 在SDK的工具链目录下,即编译工具链clang/clang 等可执行文件所在目录;
例如sdk/openharmony/10/native/llvm/bin (IDE中sdk目录结构)
或者sdk/native/llvm/bin (社区SDK目录结构)
新增工具脚本(脚本作用为封装了clang加上--target参数,方便使用,避免每次调用clang时都加上一长串命令),如下图所示
新增脚本x86_64-linux-ohos-clang以及x86_64-linux-ohos-clang ,脚本内容类似arm和arm64的脚本文件,如下
修改完毕后注意修改脚本可执行权限,chmod 777 x86_64-linux-ohos-clang x86_64-linux-ohos-clang
代码语言:shell复制vim x86_64-linux-ohos-clang
#文件内容如下
#!/bin/bash
bin_dir=`dirname "$0"`
if [ "$1" != "-cc1" ]; then
"$bin_dir/clang" --target=x86_64-linux-ohos "$@"
else
# Target is already an argument.
"$bin_dir/clang" "$@"
fi
#------------------
vim x86_64-linux-ohos-clang
#文件内容如下
#!/bin/bash
bin_dir=`dirname "$0"`
if [ "$1" != "-cc1" ]; then
"$bin_dir/clang " --target=x86_64-linux-ohos "$@"
else
# Target is already an argument.
"$bin_dir/clang " "$@"
fi
- 添加编译环境的支持
修改lycium/script/envset.sh文件,文件尾部新增如下内容
代码语言:shell复制vim lycium/script/envset.sh
setx86_64ENV() {
export AS=${OHOS_SDK}/native/llvm/bin/llvm-as
export CC=${OHOS_SDK}/native/llvm/bin/x86_64-linux-ohos-clang
export CXX=${OHOS_SDK}/native/llvm/bin/x86_64-linux-ohos-clang
export LD=${OHOS_SDK}/native/llvm/bin/ld.lld
export STRIP=${OHOS_SDK}/native/llvm/bin/llvm-strip
export RANLIB=${OHOS_SDK}/native/llvm/bin/llvm-ranlib
export OBJDUMP=${OHOS_SDK}/native/llvm/bin/llvm-objdump
export OBJCOPY=${OHOS_SDK}/native/llvm/bin/llvm-objcopy
export NM=${OHOS_SDK}/native/llvm/bin/llvm-nm
export AR=${OHOS_SDK}/native/llvm/bin/llvm-ar
export CFLAGS="-DOHOS_NDK -fPIC -D__MUSL__=1"
export CXXFLAGS="-DOHOS_NDK -fPIC -D__MUSL__=1"
export LDFLAGS=""
}
unsetx86_64ENV() {
unset AS CC CXX LD STRIP RANLIB OBJDUMP OBJCOPY NM AR CFLAGS CXXFLAGS LDFLAGS
}
二、cmake构建
在对应三方库目录,例如thirdparty/minizip-ng, 修改HPKBUILD文件,
- 在archs变量中增加x86_64, 如下图所示
三、makefile构建
在对应三方库目录,例如thirdparty/bzip2, 修改HPKBUILD文件
- 在archs变量中增加x86_64, 如下图所示
2.在prepare()函数中配置工具链,如下图
代码语言:shell复制if [ $ARCH == "x86_64" ]
then
cc=${OHOS_SDK}/native/llvm/bin/x86_64-linux-ohos-clang
ar=${OHOS_SDK}/native/llvm/bin/llvm-ar
ranlib=${OHOS_SDK}/native/llvm/bin/llvm-ranlib
fi
四、configure构建
在对应三方库目录,例如thirdparty/xz, 修改HPKBUILD文件
1.在archs变量中增加x86_64, 如下图所示
2.在prepare()函数中配置构建环境,如下图
代码语言:shell复制if [ $ARCH == "armeabi-v7a" ]
then
setarm32ENV
host=arm-linux
elif [ $ARCH == "arm64-v8a" ]
then
setarm64ENV
host=aarch64-linux
elif [ $ARCH == "x86_64" ]
then
setx86_64ENV
host=x86_64-linux
else
echo "${ARCH} not support"
return -1
fi
if $autogenflags
then
cd $builddir
./autogen.sh > $publicbuildlog 2>&1
cd ${OLDPWD}
fi
3.在recoverpkgbuildenv()函数中进行环境清理,如下图所示
代码语言:shell复制recoverpkgbuildenv() {
unset host
if [ $ARCH == "armeabi-v7a" ]
then
unsetarm32ENV
elif [ $ARCH == "arm64-v8a" ]
then
unsetarm64ENV
elif [ $ARCH == "x86_64" ]
then
unsetx86_64ENV
else
echo "${ARCH} not support"
return -1
fi
}
