从 'void*' 到 'int (*)(std::vector<deptrum::deviceinformation> &)'</deptrum::deviceinformation>
[英]invalid conversion from ‘void*’ to ‘int (*)(std::vector<deptrum::DeviceInformation>&)’
问题描述
when I run this code, it goes wrong.
当我运行这段代码时，它出错了。
void* triangle = dlopen("../lib/libdeptrum_tof.so", RTLD_LAZY);
std::vector<deptrum::DeviceInformation> device_list;
int (*GetDeviceList) (std::vector<deptrum::DeviceInformation>& device_list);
GetDeviceList = dlsym(triangle,"GetDeviceList");
Thank you for your help!!谢谢您的帮助！！

You need to use auto f = reinterpret_cast<YourFunctionType*>(dlsym(…));您需要使用auto f = reinterpret_cast<YourFunctionType*>(dlsym(…)); . .
