Exceptions in egcs (and probably gcc 2.8) have their own requirements. Since they manipulate the stack, and attempt to be thread safe, and all sorts of other fun stuff, etc, they've come up with their own incompatable way of doing things. This is fine, but requires some tweaking of egcs 1.1.1 when you build it. Not fun. There is somewhat of a solution, and that is to use setjmp and longjmp to handle exceptions. You can do this by adding the switch -fsjlj-exceptions to the CXXFLAGS before you run configure. Also keep in mind that without any effort, shared libs are somewhat broken, so to make sure mico builds, you'll want to use --disable-shared on the configure command line. What in the world are you trying to build that needs mico? If it's koffice, make sure you configure mico with --disable-ministl (or whatever it's called to make sure that the half hearted implementation of the STL isn't used). - alex | "Contrary to popular belief, penguins are not the salvation of modern | | technology.
