Re: [Tinycc-devel] TCC and round()

[Brad Elliott]

Hmm, I appear to be able to get it to work by modifying lib/msvcrt.def to link against msvcr120.dll instead of msvcr.dll and manually adding the definition for round:

 

  LIBRARY msvcr120.dll

 

  EXPORTS

  …

  round

 

Is this a safe thing to do?

Hi everyone,

 

Has anyone had success getting round() to work in TCC without implementing my own? Version 0.9.26 looks like it added support for C99 and I can see the prototype in math.h but I can’t compile it:

 

     tcc: error: undefined symbol 'round'

 

This is the simple example I was using:

 

    #include <stdio.h>

    #include <math.h>

    #include <stdlib.h>

 

    int main(void)

    {

        printf("%f\n", round(0.1));

        return EXIT_SUCCESS;

    }

 

I don’t see any options to specifically enable C99 like the --std=c99 in GCC.

 

Any ideas?

Thanks,
