I have googled all about town but with no luck on finding any info that outlines the syntax (such as wildcards, keywords, built-in functions) to aid in creating your own or modifying/fixing existing linker scripts. The gcc mailing list search did popup a nugget about symver_map language (http://gcc.gnu.org/ml/libstdc++/2004-06/msg00344.html) but didn't provide any links to get more information on the subject. Anyone know of any good resources? Thanks much. Kevin
