Re: [trinity-devel] digikam - error: invalid use of incomplete type 'png_struct {aka struct png_struct_def}'

Okay, try again. Same link. I added some extra preprocessor if statements for checking the libpng version. The patch worked fine here building against libpng 1.4.9. Your turn to test against 1.5.x. Just remember that I am very much a C++ noob. :) I built a second time without the patch, same libpng 1.4.9. The file difference between the two packages was /opt/trinity/lib/libgwenviewcore.so.1.0.0. I haven't yet performed any usability testing. I suppose opening and manipulating a PNG file should suffice. Darrell
