Thread: This program requares microsoft windows

Hello,
at university i got task to make program for old 16bit compiler C600min(C optimizing compiler version 6.0). For example:

Code:

                     //a.c
                     int main(void){
                              int a = 10;
                               return 0;
                     }

cl.exe a.c //compile and generate exe file.
Seems everything good but then i tray to execute exe file i got message "This program requares microsoft windows".
I'm using XP. May it's not possible? May i need win 3?

Thanks for any ideas.

I'm pretty sure you can work around the problem, but why are you using an ancient compiler?

The latest Visual Studio C++ 2005 Express is available from MS for free (Search for Visual Studio C++ download or some such on the MS Website). Although you may need to use a different compiler at your school, using the latest compiler at home should be OK.

So you're compiling a program in an ancient compiler and wondering why the program doesn't work on a modern OS?

Edit: I can't believe I got beaten by a millisecond.

Apparently you are using some setting that makes the executable a windows program, and the compilers code improperly checks for specific version numbers istead of the proper format of just makign sure the version is equal to or greater than a certain value. This is a common problem in older software, the only workaround is to hex edit the executable and change the version ID that it is looking for , or to disassemble the code and skip the windows check. Then again if you can find the setting in your compiler that is making this a windows executable you can make it a DOS executable, which is what you wrote it as.

Wish I hadnt lost that copy of Turbo C/C++ I had years ago.

Better yet, just go to Free Turbo C++ for Windows

Turbo C is OK if you REALLY want to create a DOS executable, but if you are actually wanting to make a Windows (32-bit) executable, then it's not such a good choice.

Why not ask the teacher for help?
