-D instructs the preprocessor (cpp, which is automatically invoked by g++) to define a symbol; the appended text is the symbol that gets defined. The meaning of the symbol depends on the source code you are compiling. Typically, preprocessor symbols are used to enable or disable features or modes of a program or library at compilation time (i.e. the option isn't configurable at run time). You need to either look in the documentation for the source package you are compiling, or failing that grep the source for U_STATIC_IMPLEMENTATION and try to discover from the source what it is doing. E.g.: grep -r U_STATIC_IMPLEMENTATION . in the source base directory. -- Barry -- http://barrkel.blogspot.com/ -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
