    Linker error using system(*.*)

    OS: Win2k
    Compiler: Borland Turbo C++ v 4.52

    #include <stdlib.h>
    #include <stdio.h>
    int main(void)
       printf("About to spawn and run a DOS command\n");
       return 0;
    The above code compiles just fine. When I rebuild (which includes linking) I get the following error message:

    Compiling TEST1.CPP:
    Linking test1.exe:
    Linker Warning: No module definition file specified: using defaults
    Linker Error: Undefined symbol _system in module TEST1.CPP.

    (Throws the same linker error for all of the "execl" series commands as well.)

    I've changed the system command to system() and rebuilt. The error changes to a compile error "too few parameters in call to system(const *char)... like we would normally expect.

    I have a feeling I'm missing something really simple here but, not having seen this before, I am at a loss.

    Any kick in the right direction would be greatly appreciated.

    Many thanks!

    Lightbulb Enterprise Compiler

    I would bite on the student version angle if I weren't using an Enterprise edition.

    But, I think you may be on to something. I'll try a different compiler.

    Thank you, Salem.

    Different Compiler Worked

    Many Thanks, Salem: The third compiler worked!

    For anyone interested: The compiler that ended up doing the job was the Bloodshed Dev-C++. A freebie that, at least initially, looks as capable as anything I've been exposed to thus far.

    In regard to the first posting, what type of target are you trying to build? I get this same linker output when I set the target platform to Windows 3.x (16). As a Win32 Console app it's fine.
    7. It is easier to write an incorrect program than understand a correct one.
    40. There are two ways to write error-free programs; only the third one works.*

    Dave_Sinkula: direct hit!

    Changed target type to Application, Win32, Console and rebuild the source file.

    EUREKA! A perfect compile and link.

    I'd like to take this opportunity to thank everyone who took the time to change into boots and give me a good kick. My rear-end is pretty sore now. I'm taking my ball and going home.......

    And just to clarify:
    >>The compiler that ended up doing the job was the Bloodshed Dev-C++<<
    Bloodshed is not a compiler, it's an IDE.

    But, hey, it did the job, so who cares
    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]
