Compiling ecl-0.9i (with sockets and threads) from tarball on Windows XP using VC8 getting these errors. ecl-threads.def : error LNK2001: unresolved external symbol ecl_base_string_case ecl-threads.def : error LNK2001: unresolved external symbol si_set_funcallable Commented out those symbols in ecl-theads.def and was ok.
