Patch fixing the problem.
Version: 1.8.0 (using KDE 4.5.4)
OS: All
In png-1.5, the prototype for png_set_iCCCP changed. The fifth argument was a
png_charp and is now a png_bytep.
Reproducible: Always
Steps to Reproduce:
Compile digikam against png-1.5.
Actual Results:
Here's the output from digikam-1.6.0, but the code is the same in SVN:
libs/dimg/loaders/pngloader.cpp: In member function 'virtual bool
Digikam::PNGLoader::load(const QString&, Digikam::DImgLoaderObserver*)':
libs/dimg/loaders/pngloader.cpp:501: error: invalid conversion from 'char**' to
'png_byte**'
libs/dimg/loaders/pngloader.cpp:501: error: initializing argument 5 of
'png_uint_32 png_get_iCCP(const png_struct*, const png_info*, char**, int*,
png_byte**, png_uint_32*)'
libs/dimg/loaders/pngloader.cpp: In member function 'virtual bool
Digikam::PNGLoader::save(const QString&, Digikam::DImgLoaderObserver*)':
libs/dimg/loaders/pngloader.cpp:733: error: invalid conversion from 'char*' to
'const png_byte*'
libs/dimg/loaders/pngloader.cpp:733: error: initializing argument 5 of 'void
png_set_iCCP(png_struct*, png_info*, const char*, int, const png_byte*,
png_uint_32)'
Expected Results:
Successful compilation :)
I've attached a patch that fixes the problem with 1.5.0.
It probably needs changes to still work against older versions (which I don't
have installed).
