Errors in Unix to Windows conversion

I'm trying to port an algoreithm from a unix program to something that will compile in visual studio. I've had to find and include a unistd.h a getopt.c and a stdint.h I found online. I'm still getting some errors that might be because of differences between systems.

1st error
Error 4 error C2371: 'int8_t' : redefinition; different basic types c:\users\minion\documents\visual studio 2008\library\bam2bed\stdint.h 82 BAM2BED




#include <limits.h>

// For Visual Studio 6 in C++ mode and for many Visual Studio versions when
// compiling for ARM we should wrap <wchar.h> include with 'extern "C++" {}'
// or compiler give many errors like this:

typedef unsigned __int32 uint32_t;
#endif

second error
Error 5 error C2039: 'isdigit' : is not a member of 'std' c:\users\minion\documents\visual studio 2008\library\bam2bed\bedfile.h 336 BAM2BED

return 0;
}

for (int i = 0; i < len; i++) {
if (!std::isdigit(s)) return false; //ERROR IS HERE
}
return true;
}


// return the amount of overlap between two features. Negative if none and the
// number of negative bases is the distance between the two.
inline
int overlaps(CHRPOS aS, CHRPOS aE, CHRPOS bS, CHRPOS bE) {
return min(aE, bE) - max(aS, bS);
}

// is A after (to the right of) B?
inline
bool after(const BED &a, const BED &b) {
return (a.start >= b.end);
}


what might the fix be?

Likely the problem with error 1 is resultant from a different error elsewhere. The error message is pretty description, you're defining int8_t twice, probably with different types.

The second error is probably due to not including <cctype>. See http://www.cplusplus.com/reference/clibrary/cctype/isdigit/

I do see int8_t being defined twice once as a signed char and another as a signed int8 below. Is this the acutal mistake or is it allowable and there must be something else wrong? But as I got this code somewhere else I assumed that it was correct for unix

#if (_MSC_VER < 1300)
typedef signed char int8_t;
typedef signed short int16_t;
typedef signed int int32_t;
typedef unsigned char uint8_t;
typedef unsigned short uint16_t;
typedef unsigned int uint32_t;
#else
typedef signed __int8 int8_t; //ERROR IS HERE
Due to the ifdef there, the line right below the _MSC_VER check and the line right below the #else are not going to both be compiled. One or the other will be.

You likely have another, seemingly unrelated definition of int8_t some additional place. VS is pretty good about finding these things, if you just ask it to find the definition of it.
