Package: libpng++-dev
Version: 0.2.5-1
When trying to compile https://github.com/Malvineous/libgamegraphics I got an
error during configure:
checking if png++ is new enough... configure: error: png++ is too old.
Please download and install png++ newer than 0.2.5.
However when I checked I did have png++ 0.2.5 or newer:
host$ dpkg -l libpng++-dev | tail -1
ii libpng++-dev 0.2.5-1 all C++
interface to the PNG (Portable Network Graphics) library
So I went about digging through config.log and found that the program configure
was compiling to determine if the installed png++ was>= 0.2.5 caused ae error.
I distilled the program further and arrived at this:
host$ cat bug.cpp
#include <png++/png.hpp>
int main ()
{
std::string fn;
png::image<png::index_pixel> png(fn);
return 0;
}
When I try to compile this I get an error message:
host$ g++ -o bug -I/usr/include/libpng12 bug.cpp -lpng
In file included from /usr/include/png++/png.hpp:55:0,
from bug.cpp:1:

transform(rd);
^
At this point I started browsing the patches applied to png++ after 0.2.5 was
released to see if there was anything that could solve my problem. After some
digging I found that r120 indeed contained a patch that resolved the error:
http://svn.savannah.nongnu.org/viewvc?view=rev&root=pngpp&revision=120
http://svn.savannah.nongnu.org/viewvc/trunk/convert_color_space.hpp?root=pngpp&r1=109&r2=120&pathrev=120
I applied these changes and afterwards I could compile the program without
errors:
host$ g++ -o bug -I/usr/include/libpng12 bug.cpp -lpng
host$ echo $?
0
Running the program still fails, but configure never actually links the program,
so this is expected:
host$ ./bug
terminate called after throwing an instance of 'png::std_error'
what(): : No such file or directory
Aborted
For your reference I'm using this version of g++:
host$ dpkg -l g++ | tail -1
ii g++ 4:4.8.1-3 amd64 GNU C++
compiler
I would appreciate if at least the patch in r120 was applied in Debians repo
and released as 0.2.5-2 or similar. This would mean that I would no longer
encounter an error. Thanks! :)

Description:
libpng++-dev - C++ interface to the PNG (Portable Network Graphics) library
Closes: 733231
Changes:
png++ (0.2.9-1) unstable; urgency=medium
.
* New upstream release. (Closes: #733231)
* Add myself to Uploaders, thanks Jonas for the offer.
* Also adding myself to d/copyright.
* Refresh patch 1001_avoid_MAKEFLAGS.patch.
* Remove patch 1002-libpng16.patch, no longer needed.
* Changing to short debhelper format:
- refactor d/rules.
- drop B-D on cdbs and dh_buildinfo.
- introduce d/clean, /*.install, d/*.docs and d/*.examples.
- drop d/README.source, d/copyright_hints and d/control.in.
* Bump S-V to 3.9.6, no changes required.
* Fix also VCS-Git to canonical format.
* New patch 1004-use-imagemagick-compare-for-testsuite.patch, avoiding
rounding errors in the testsuite by allowing some fuzz. This requires
imagemagick as new B-D.
* Add a lintian override for doxygen's jquery.
