[Quantlib-users] Failing to run Quantlib 'Hello World' code

[Christofer B. <bog...@gm...>]

Hi,

I installed Quantlib in a custom folder, and then ran following 'Hello
World' code

#include <iostream>
#include <ql/interestrate.hpp>

int main()
{
std::cout << "Hello World" << std::endl;
}

Above code fails with below error message

Build finished with error(s).

 *  The terminal process failed to launch (exit code: -1).
 *  Terminal will be reused by tasks, press any key to close it.

I am using Mac and VScode to run the C++ code.

Could you please suggest if I need to perform anything specific to run
above code? I mostly followed the instructions in
https://www.quantlib.org/install/macosx.shtml to install Quantlib in
my Mac.

Any pointer will be very helpful.

Many thanks,
