Description Roby 2010-05-25 14:20:47 UTC

I have only libpng 1.4.2 on the system. I installed povray-3.7.0.beta.35a and it gave me this error message:

The problem is here,

image/png.cpp:464: error: ‘struct png_info_struct’ has no member named ‘trans_alpha’
image/png.cpp:495: error: ‘struct png_info_struct’ has no member named ‘trans_alpha’

I'd like to point out that libpng-1.4.2 _has_ 'trans_alpha'. 

So, above error would happen if you had old libpng 1.2 headers installed somewhere on your system, that's pngconf.h and png.h. Perhaps check your /usr/local for old files ? Something like:

find /usr/include -name '*png*.h'
find /usr/local -name '*png*.h'

Verified it's fine with libpng 1.4.2 here, so it's a local problem. Closing as NEEDINFO, reopen if it still fails after fixing the system from old libpng headers.
