[Libexif-devel] Compiling from CVS

[Antonio S. <sc...@te...>]

   Hi,

   Since I did not find the 0.6.9 tar I updated from CVS to compile it and=
=20
here are some comments:

1) Would be very nice to have a function like:

const char *
exif_tag_get_name_index (unsigned int i, ExifTag *tag)
{
   if (!ExifTagTable[i].name)
     return NULL;

   *tag =3D ExifTagTable[i].tag;

	return (ExifTagTable[i].name);
}

   in "exif-tag.c". It allows me to scan over all the defined tags.

2) The file "exif-data.c" depends on the header file "jpeg-marker.h" that=20
it is in the pack, but outside the library folder. Why not to move this=20
header to the libexif folder?

  Also Open Watcom complained about it:

libjpeg/jpeg-marker.h(27): Error! E1115: Incomplete enum declaration

   I change to the old version.

3) I created a simple "_stdint.h" by hand from Cygwin "stdint.h", all the=20
platforms I use the types used have fixed sizes. The "_stdint.h" is a good=
=20
solution for the library users.

4) I still use the same "config.h" that I mention before:

#define GETTEXT_PACKAGE "libexif-9"

#ifdef WIN32
#define snprintf _snprintf
#endif

5) I have to edit the function exif_entry_initialize from "exif-entry.c".=20
There are lots of uninitialized tags. I simply replace the function with my=
=20
version. Then saving exif tags in jpeg came back to normal.

   That=B4s it. This is working in Windows (gcc3, Mingw3, OpenWatcom, VC6=
 and=20
VC7) and in UNIX (Linux, IRIX, AIX and SunOS).  libexif is used internally=
=20
by an also free library called IM. I updated the library this month. You=20
may find it at:

   Issues 1 and 2 are not a big deal, but I would appreciate if you guys=20
can think about issue 5. I can send you my version of the function attached.

Best,
scuri
