With some help from Brian and Julian, I finally got my library working on Linux. There was one issue in building the system from the current CVS, apart from applying Brian´s patches: In src/cmp/cmpcfg.lsp.in, the line (setq *ld-format* "@ECL_CC@ -o ~A -L~A ~{~A ~} ~@?") should be (setq *ld-format* "~A -o ~A -L~A ~{~A ~} ~@?")
