Hello Massimo

I wanted to compile TestLeptonica package in Windows but I have had some problems. I have used MinGW as it has simpler errors.

As there was errors for not finding png.h, tif.h and zlib.h I have added these internal includes to package:

../../uppsrc/plugin/png
../../uppsrc/plugin/tif/lib
../../uppsrc/plugin/z/lib

Compiling I get this errror:

In file included from C:\upp\uppsrc/Draw/Draw.h:6:0,
from C:\upp\uppsrc\plugin\png/png.h:4,
from C:\upp\bazaar\PixRaster\lib\pngio.c:110:
C:\upp\uppsrc/Core/Core.h:39:20: fatal error: typeinfo: No such file or directory

Do you have any idea?

You should add 'lib' as internal includes to package plugin/jpg, plugin/tif and plugin/z using package organizer. I've solved it.
However, another error occurs. My platform is Win32, so 'fh' is defined as 'HANDLE',but my compiler(mingw) report an error about the function 'fdopen', see below.

bool Pix::Load(FileIn &fs, int page)
{
int format;
#ifdef WIN32
HANDLE fh;
#else
int fh;
#endif

Destroy();

fh = fs.GetHandle();
if (!fh)
return false;
FILE *fp = fdopen(fh, "r");
if(!fp)
return false;
...
}
error message:
G:\MyApps\PixRaster\PixRaster.cpp:792:27: error: invalid conversion from 'void*' to 'int'
G:\MyApps\PixRaster\PixRaster.cpp:792:27: error: initializing argument 1 of 'FILE* fdopen(int, const char*)'
