I found a couple of posts where name clashing did occur (not with X). Other modules in X using lex & yacc are the server and apps, but this module is a library and more prone to name clashing. Looking at external symbols of X libraries, it shows that they have a prefix, for example, Xaw. In fact, a prefix for libraries external symbols is a GNU coding standard. One thing I don't know is if these yy* symbols should be external symbols or not. If yes, they should have an Xaw3d prefix, otherwise they should be made invisible. I don't know if this would be possible, however. <BLOCKQUOTE TYPE=CITE> <TT>What confuses me is why does it come up here (Layout.c)</TT> <TT>I would expect it with Layout.h</TT> </BLOCKQUOTE> Maybe because the author did not want those to be in the public headers space (include/X11/Xaw3d/Layout.h). </BODY> </HTML>
