Hi,
I have a problem on my mac when trying in R to produce png images.
I am getting this warnings:
libpng warning: Application built with libpng-1.2.26 but running with 1.5.2
I am running the R 2.14 version using the R studio GUI.
I am not excatly sure about the libpng problem.
When I am doing locate libpng-config
I'm getting several hits, some with libong-config12, some with libpng-config14, some without nay numbers:
ayeroslaviz:~ ayeroslaviz$ locate libpng-config
/Applications/XAMPP/xamppfiles/bin/libpng-config
/Library/Frameworks/GTK+.framework/Versions/2.18.X11/Resources/bin/libpng-config
/opt/local/bin/libpng-config
/usr/X11/bin/libpng-config
/usr/local/bin/libpng-config
When doing which libpng-config I'm getting:
/usr/local/bin/libpng-config
Is there a way to uninstall older versions of libpng or update the paths to the right version. Unfortunately I am not even sure, what thesource of this warning, so I hope I gave here all the needed information.
I would be grateful for anyone who gives me a hint about how to solve this problem.
thanks
A.
