I don’t know if you want me reporting a cvs compile error, so if this project does not want that please say so. Anyway, I am having a problem compiling from cvs. I have a ubuntu feisty box and libart failed the configure saying png.h is not found. Are there any ideas. I have looked and there is png.h in /usr/include/libpng12/png.h and there is a symlink to that in /usr/include/png.h and /usr/include/libpng/png.h. Do you need any more info? Also, what is the criteria for the next release? It is annoying to have to keep recompiling from cvs. I would like to have base to write my programs off of that ubuntu can package. So what needs to be done? Thanks * * * Take Surveys. Earn Cash.

There is no pkgconfig file so the same fix won’t work. The file is installed and located in /usr/include/. Thanks * * * Take Surveys. Earn Cash.
