    Compiler issues in C in MSVisStudio2010 cl cmd compiler vs other (gcc/tcc)

    Hi
    I have recently tried compiling C code 'secondchess.c' in Win7 with MSVisStudio2010 cl cmd compiler & this returns a whole bunch of errors/warnings etc. I also have TCC compiler on my Win7 machine & used it to compile the code which it did without any complaint!
    See my thread on chess2u forum about this:
    SecondChess - Page 2

    I am a very inexperienced coder but would like to try to use standards compliant code & so I am very grateful if someone can help me sort out the errors this code gets in MSvisStudio2010 cl compiler.
    (As in my chess forum post I have spent a lot of time already trying to fix this but with no success-please remember I am an amateur programmer & new to C/C++).

    These are the first errors given:
    Code:
    secondchess.c(785) : error C2143: syntax error : missing ';' before 'type'
    secondchess.c(789) : error C2143: syntax error : missing ';' before 'type'
    secondchess.c(792) : error C2065: 'i' : undeclared identifier
    & I have tried to fix them but no result & there are so many more errors! Why does MSVisStudio2010 cl compiler baulk at this & yet tcc (& gcc-I think but I have not used gcc as I'm on Win7) doesn't?

    Thanks

    The problem was, the source code wasn't compiled originally with strict C89 conformance.

    Code:
    int Eval()
    {
    
       //!! this is a statement
       count_evaluations++;
    
       //!! this is a declaration
       /* A counter for the board squares */
       int i;
    
       /* The score of the position */
       int score = 0;
    Most modern compilers now support C99, which allows such things.

    But MS will never update their C compiler to C99, so you're stuck with just C89 on that compiler.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Without seeing the actual code, I can only surmise you're running into Microsoft's unwillingness to update their C compiler to a newer standard than C89 (I think that's the one they adhere to). In C89 and prior, all type declarations must precede any actual code.

    EDIT: Damn, too slow!

    Thanks for your quick & helpful reply. I am googling this to find more info & how to fix it.
    I have run secondchess.c as an empty project in MSVisStudio2010 but still get many errors eg:

    How much of the work are you prepared to do?

    Because we're not a "I found some code, please fix it for me" kind of site. These kinds of fixes are best done by the authors/maintainers so that everyone benefits.

    All these would be fixed if you moved count_evaluations++; down a few lines.

    Similarly, look at the other similar error messages caused by mixing declarations and statements. Move the statements!
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Without looking at the code at all, perhaps try building it as C++. Since C++ allows you to mix declarations and other code, you'd at least move on to a new list of errors.
