[Digikam-devel] compilation error

[Peter Akos]

Hello!

I have an error when trying to compile digikam 0.9.0-rc2.

In file included from dimg.cpp:44:
../../../digikam/libs/dimg/loaders/pngloader.h:59: error: `va_list' has not
been declared
../../../digikam/libs/dimg/loaders/pngloader.h:59: error: ISO C++ forbids
declaration of `operands' with no type
make[5]: *** [dimg.lo] Error 1

-- digiKam configure results -------------------
-- sqlite3 found.................. YES
-- libgphoto2 found............... YES
-- libkipi found.................. YES
-- libtiff found.................. YES
-- libpng found................... YES
-- lcms found..................... YES
-- Exiv2 library found............ YES
------------------------------------------------

Good - your configure finished. Start make now

gcc 3.4.6
qt 3.3.6
libpng 1.2.8
exiv2 0.12

Is there anything I can do to make it work?
Thank you for the help.

Yes.  i suspect than a C ANSI header is missing in your libpng.h.

Edit the file digikam/libs/dimg/loaders/pngloader.h and add

#include <stdarg.h>

...on line 26. You will have something like that :

---------------------------------------------------------

#define PNGLOADER_H

extern "C"
{
#include <stdarg.h>
#include <png.h>
}

// Local includes.

---------------------------------------------------------

... and try to recompile all
