Yes this worked in my ming build (just now), i set all
"struct stat" to "struct stat64"
and lstat -> lstat64
and
#ifdef _WIN32
#define lstat64(x,y) stat64(x,y)
#endif
but now the cygwin compilation has complaints:
stat64 statStruct’ has incomplete type and cannot be defined
struct stat64 statStruct;
^
/f/gdl/src/file.cpp:402:58: error: ‘lstat64’ was not declared in this scope
int actStat = lstat64( testFile.c_str(), &statStruct);
^
/so I take a look at the cygwin64 /usr/include/sys/stat.h, I can't find
lstat64 at all:
greg@Homerw7 /f/gdl/src
$ grep lstat /usr/include/sys/stat.h
int _EXFUN(lstat,( const char *__restrict __path, struct stat
*__restrict __buf ));
$ grep -B3 -A2 stat64 /usr/include/sys/stat.h
#ifdef __CYGWIN__
#include <cygwin/stat.h>
#ifdef _COMPILING_NEWLIB
#define stat64 stat
#endif
#else
--
int _EXFUN(_stat,( const char *__restrict __path, struct stat
*__restrict __sbuf ));
int _EXFUN(_mkdir,( const char *_path, mode_t __mode ));
#ifdef __LARGE64_FILES
struct stat64;
int _EXFUN(_stat64,( const char *__restrict __path, struct stat64
*__restrict __sbuf ));
int _EXFUN(_fstat64,( int __fd, struct stat64 *__sbuf ));
#endif
#endif
