I am running R 2.10 on SuSE 9.3. When I tried to install the package "rgl", I got error message: ... In file included from pixmap.cpp:13: pngpixmap.h: In static member function `static void PNGPixmapFormat::Load::info_callback(png_struct*, png_info*)': pngpixmap.h:149: error: invalid conversion from `long unsigned int*' to ` png_uint_32*' pngpixmap.h:149: error: invalid conversion from `long unsigned int*' to ` png_uint_32*' make: *** [pixmap.o] Error 1 ERROR: compilation failed for package 'rgl' ** Removing '/usr/local/lib/R/library/rgl' ** Restoring previous '/usr/local/lib/R/library/rgl' ... Any ideas why? Shige
