Hello, as recomended i tried to set the following enviornment variables. CPPFLAGS LDFLAGS PKG_CONFIG_PATH LD_LIBRARY_PATH to my surprise i get error st. command not found on running printenv or env the list of variavle,value that i get does not include any of these on running env CPPFLAGS="xyz" this variable,value does gets added to the end of the list but on running env again , it is again missing from the list man env says run COMMAND after setting the value this too is not improving the situation please let me know where could the problem lie. Thank You _______________________________________________ gtk-list@xxxxxxxxx http://mail.gnome.org/mailman/listinfo/gtk-list
