After removing intel toolkit, g++ looking for intel math library and complain error

[BenTanison12]

This is centos system. I have installed intel HPC toolkit(toolkit before intel OneAPI, including intel C++/c/fortan/MKL...). Then after I remove the intel toolkit, my g++ didn't work (so does my gcc, same error). It seems the g++ is looking for intel math library. Since I removed the intel toolkit, it can not find the intel math library and complain error.

How can I tell g++ do not to find intel math library? And how can I know what library g++ are looking for?

Thank you for your help!

The c++ example

#include<iostream> #include<cmath>
int main(){
int a = 1<<31;
std::cout<<"a is "<< a <<std::endl;
int b = std::abs(a);
std::cout<<"b is "<< b <<std::endl;
return 0;
}

the command I used to compile the c++ example

g++ a.cpp
the error it complain

Hi Ben, Intel® oneAPI HPC Toolkit has internal dependencies on Intel® oneAPI Base Toolkit. Thus, we suggest our users to install the Intel® oneAPI Base Toolkit first followed by Intel® oneAPI HPC Toolkit. Intel® oneAPI HPC Toolkit requires the Base Toolkit for optimum performance.

Thus, we suggest you to re-install the Intel® oneAPI Base Toolkit.

Ben, unfortunately we were unable to hear back from you.

If you have any further queries, please post a new question as this thread will no longer be monitored by Intel®.
