The readme for SDL_image doesn't say anything about incompatible
versions of libpng - I have version 1.2.46 installed along with
the dev files. It also says zlib is required and those are also
installed.
On the project page[1] is lists libpng 1.5.7 as being used for
the pre-built binaries (presumably for Win) although the link it
provides is dead.
libpng 1.5.2 is the nearest version on that project page[2]. I
built that then rebuilt SDL_image. dub --force now gives me:
IMG_Load error: Failed loading png_set_longjmp_fn:
/lib/i386-linux-gnu/libpng12.so.0: undefined symbol:
_png_set_longjmp_fn
Which looks like it is still referring to the old version of
libpng.
I downloaded the source for the latest version of libpng but
there is no simple install procedure - the configuration required
is beyond my level of knowledge.
This thread has degenerated into a discussion of the set up of my
OS which is miles off topic and should probably be abandoned.
Thanks for trying all the same.
