Hi everybody who might find this relevant
This is a suggestion for what you could do if want to have PNGwriter working under opSuSE 11.3.
I am pretty new to linux, but I am using openSuSE 11.3 and have just used about 4 hour getting PNGwriter to work.
PNGwriter wouldn't work with libpng 1.4 devel (the libpng14-devel package), when I e.g. tried to compile the first example from the manual as described in the manual, I got an error saying:
/usr/local/lib/libpngwriter.a(pngwriter.o): In function `pngwriter::readfromfile(char*)':
/path-to-the-pngwriterdirectory/pngwriter-0.5.4/src/pngwriter.cc:1314: undefined reference to `png_set_gray_1_2_4_to_8'
collect2: ld returned 1 exit status
but when I removed the libpng14-devel (and the libpng14-compat-devel) package and instead installed the libpng12-devel package and the libpng12-compat-devel package it works.
To get to this point however, I first had to set up a symbolic link in /usr/include/ to /usr/include/freetype2/freetype to get the compiler to stop complaining about freetype.
I hope this will a help to anybody who wants PNGwriter under openSuSE.
And Poul, you might want to look into libpng 1.4 at some point (when you have some excess time)
Hi, maybe the patch to this bug report can help you?
