Depends on your system and if C code has debug info. The gdb approach I use (linux/solaris) is like this: gdb perl handle SIGWINCH pass nostop noprint break XS_DynaLoader_dl_find_symbol break Perl_vmess run -Mblib yourscript ... break SymbolInSo -------------------------------- The break on XS_DynaLoader_dl_find_symbol happens just after the .so is loaded as perl is about to define the "bootstrap" symbol. So when you hit that you can set break points on symbols in your .so file. Note that you may well hit dl_find_symbol several times before you get to yours (common things like Cwd.so get loaded too). So you may have to "keep trying" till setting breakpoint succeeds. Same basic idea works with gdb and MinGW on Win32. Visual Studio is possible too same scheme in outline but harder to "script".
