[Dev-C++] Conversion to Dev-C++

[Bill W. <bil...@at...>]

Hello all!
This is a two-part appeal:
I am have having difficulty porting some code from our borland 5.02 C++ =
and our Sun Solaris C++ compilers.  We build this code (libraries and =
CGI executable drivers) on both platforms and I am trying to consoidate =
our codebase to one compiler (gcc) for both environments.

I am getting the following messages when there is a module using the =
lstat and getwd structs defined in sys/stat.h

'implicit declaration of function int getwd(...)'  and
'implicit declaration of function int lstat(...)'

The actual code is prety straight-forward:

int stat_value;
struct stat statv;
struct stat dbuf;
struct dirent *dirent_save;

getwd(dirnow);
      buf =3D opendir(dirnow);
      stat_value =3D stat(dirent_save->d_name,&dbuf);
          if(dirent_save->d_name[0] !=3D '.')
              lstat(dirent_save->d_name,&statv);

I need help in trying to resolve this.

Secondly, we also use the sqltypes.h header and it reports tons of =
errors due to some intrinsic types that do not seem to be defined.  Does =
anyone know what additional headers need to be pulled in if sqltypes.h =
is used?

Thanks in advance
Bill

You may need to use fstat and not lstat. A quick look at sys/types.h
shows there is no lstat. Also, you may need to do a:

#define    fstat   _fstat

to make it work with "fstat" as the MSCRT mangles the standard C
function names by placing "_" in front of this (which I do not fully
understand).

In my mingw sys/types.h

int     _fstat (int, struct _stat*);
int     _chmod (const char*, int);
int     _stat (const char*, struct _stat*);

As for getwd(), however, in io.h, this is defined:

char*   _getcwd (char*, int);

Could you use it instead?

#include <windows.h>
#include <sqltypes.h>
