在 Mac [XCode] 上用 c++ 打开一个附加程序

Question

I want to open an additional program with c++ on XCode. It is Firefox. But if I make

Shell Execute("file://localhost/Applications/Firefox.app"); 

There is an error 'ShellExecute' was not declared in this scope In other forum there was a clue to include windows.h and shellapi.h

#include <shellapi.h>
#include <windows.h>

but that makes other errors

shellapi.h: No such file or directory
windows.h: No such file or directory

What should I do? I want to open frefox with c++ in XCode on Mac?

Answer 1

ShellExecute() is only available through the Windows API. You don't have a Windows system.

You can simply use the (more portable) system() function, or one of the exec() functions available on POSIX compliant systems.

Answer 2

Try running this in Terminal to open Firefox:

open -a Firefox http://www.ibm.com

If that does what you want, you need to wrap it in system() like this:

#include <cstdlib>
#include <fstream>
#include <iostream>

int main()
{
    std::system("open -a Firefox");
}

Answer 3

I tried the same with chrome and I had to set it in inverted commas:

int main() {
    system("open -a 'Google Chrome'");


    return 0;
}

with the apostrophe it worked!
