这个问题出现在高通的Android高版本的源码编译的场合，解决办法能搜到一个stack上的解答，但是已经不适合当前的版本。
下面给出我发现的解决办法：
1.先要在任意一个vendorsetup.sh中添加变量。
export SDCLANG_AE_CONFIG=“device/qcom/common/sdclang.json”
我这里添加在device/qcom/common/vendorsetup.sh
2.添加sdclang.json
位置要和上面的路径一致，内容举例如下所示。
{
“default”: {
“SDCLANG”: false,
“SDCLANG_PATH”: “vendor/qcom/proprietary/llvm-arm-toolchain-ship/3.9/bin”,
“SDCLANG_PATH_2”: “vendor/qcom/proprietary/llvm-arm-toolchain-ship/4.0/bin”,
“SDCLANG_FLAGS”: “-Wno-vectorizer-no-neon”,
“SDCLANG_FLAGS_2”: “-Wno-vectorizer-no-neon”
},
“msmnile”: {
“SDCLANG”: true,
“SDCLANG_PATH”: “vendor/qcom/proprietary/llvm-arm-toolchain-ship/3.9/bin”,
“SDCLANG_PATH_2”: “vendor/qcom/proprietary/llvm-arm-toolchain-ship/4.0/bin”,
“SDCLANG_FLAGS”: “-Wno-vectorizer-no-neon”,
“SDCLANG_FLAGS_2”: “-Wno-vectorizer-no-neon”
},
“msm8998”: {
“SDCLANG”: true,
“SDCLANG_PATH”: “device/qcom/common/llvm-arm-toolchain-ship/4.0/bin”,
“SDCLANG_PATH_2”: “device/qcom/common/llvm-arm-toolchain-ship/4.0/bin”,
“SDCLANG_FLAGS”: “-Wno-vectorizer-no-neon”,
“SDCLANG_FLAGS_2”: “-Wno-vectorizer-no-neon”
},
}
3.sdclang对应的工具可使用OnePlus在github上的开源代码中的工具。
