Mac编译时，遇到Undefined symbol: typeinfo for AlibabaCloud::OSS::OssObjectRequest

dataonfirecn commented 4 years ago

在Mac 10.15 catalina，使用OpenlSSL 1.0.2p打包静态库libalibabacloud-oss-cpp-sdk.a(15.7M)

其中有个方法： bool OSSdeleteObject(const std::string& accessKeyId, const std::string& accessKeySecret, const std::string& endpoint, const std::string& bucketName, const std::string& objName) { std::string ObjectName = objName;

InitializeSdk();

ClientConfiguration conf;
OssClient client(endpoint, accessKeyId, accessKeySecret, conf);

DeleteObjectRequest request(bucketName, ObjectName);

auto outcome = client.DeleteObject(request);

if (!outcome.isSuccess()) {
    std::cout << "DeleteObject fail" <<
        ",code:" << outcome.error().Code() <<
        ",message:" << outcome.error().Message() <<
        ",requestId:" << outcome.error().RequestId() << std::endl;
    ShutdownSdk();
    return false;
}

ShutdownSdk();
return true;

}

在编译案例时（已导入libcrypto.a, libcurl.a, libssl.a)，遇到linker错误： Undefined symbols for architecture x86_64: "typeinfo for AlibabaCloud::OSS::OssObjectRequest", referenced from: typeinfo for AlibabaCloud::OSS::DeleteObjectRequest in YEEOss.o ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation)

注释掉删除Object方法中的： DeleteObjectRequest request(bucketName, ObjectName);

编辑正常，upload，download功能都没问题。

请教是在哪个环节可能出现错误？谢谢

和 RTTI 的编译选项有关系，当前版本默认关闭 rtti ，即构建时增加了 -fno-rtti 选项，所以你的代码编译时，也需要加上 -fno-rtti 。

之后的版本会增加一个 CMake 选项， ENABLE_RTTI，默认为 ON ，业务方可以根据需求设置。
