[postgis-users] Error compiling geos 2.1.0 on Windows/MinGW

[TECHER Jean David]

Hi 

I tried to compil geos 2.1.0 on Windows XP using MinGW

I got this error 


g++ -DHAVE_CONFIG_H -I. -I. -I../../source/headers -I../../source/headers/geos -I../../source/headers -DGEOS_VERSION=2.1.0 -g -O2 -MT Profiler.lo -MD -MP -MF .deps/Profiler.Tpo -c ../util/Profiler.cpp  -DDLL_EXPORT -DPIC -o .libs/Profiler.o
../util/Profiler.cpp: In member function `void geos::Profile::start()':
../util/Profiler.cpp:36: `gettimeofday' undeclared (first use this function)
../util/Profiler.cpp:36: (Each undeclared identifier is reported only once for 
   each function it appears in.)
make[2]: *** [Profiler.lo] Error 1
make[2]: Leaving directory `/home/src-2004-11-26/geos-2.1.0/source/geom'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/home/src-2004-11-26/geos-2.1.0/source'
make: *** [all-recursive] Error 1

As I'm not a great C++ programer I saw that gettimeofday'  is not in my sources from MinGW

On the Web , I found this code but not sure for his need 

typedef struct _FILETIME {
        unsigned long dwLowDateTime;
        unsigned long dwHighDateTime;
   } FILETIME;
   void __stdcall GetSystemTimeAsFileTime(FILETIME*);
   
   void gettimeofday(struct timeval* p, void* tz /* IGNORED */);

   void gettimeofday(struct timeval* p, void* tz /* IGNORED */){
     union {
       long long ns100; /*time since 1 Jan 1601 in 100ns units */
       FILETIME ft;
     } _now;

     GetSystemTimeAsFileTime( &(_now.ft) );
     p->tv_usec=(long)((_now.ns100 / 10LL) % 1000000LL );
     p->tv_sec= (long)((_now.ns100-(116444736000000000LL))/10000000LL);
     return;
   }

Putting it on Profiler.cpp work but make stopped for XMLTester.exe

Any Ideas???
