jGrasp Compile Error

I am trying to compile a program in jGrasp, but every time I try I receive an error -

Quote:

----jGRASP exec: g++ -g C:\Users\Christopher\Documents\New Folder\Hello World.cpp

----jGRASP wedge2 error: command "g++" not found.
---- This command must be in the current working directory
---- or on the current PATH to use this function.

...so is g++ installed within cygwin? If not, then run the cygwin setup, and pick g++ from the development list of packages.

Ok, so I installed it making sure g++ was checked. Now I receive the following error -

Code:

 ----jGRASP exec: g++ -g C:\Users\Christopher\Documents\New Folder\Hello World.cpp

 ----jGRASP wedge2: exit code for process is 1.
 ----jGRASP: operation complete.

I just wanted to see if it worked, so here is the code I used -

CPP / C++ / C Code:

#include <iostream.h>

main()
{
    cout << "Hello World!";
    return 0;
}

I don't think that g++ accepted that path (having spaces) as a valid input file.

One thing to try, is to replace the spaces with underscores, and that should help. But if not, post another reply.

Spaces aren't the problem unless it's a very old version of jGRASP (like ten years old).

You can turn on "Settings" / "Verbose Messages" in jGRASP to see the full path to the g++ that gets called and the quoted arguments (labeled as "actual command sent").

I'm guessing that you're missing something else from Cygwin (maybe the "wrong" preprocessor is being called or something). If you have the disk space, the easiest thing is just to install everything from Cygwin (takes a while though). Otherwise, you can add a "-v" flag to the compile-and-link command to see the details of what "g++" is doing.
