Elliot, if you give me a script to compile the DLLs with GCC (I have<br>
the memutil one, but not the libberkeley-db.dll and following what is<br>
wirttten in the .ASD file doesn't produce for me the DLLs), I could<br>
start learning the GDB to try to see what happens on the C-side in the<br>
spare free time. Or I could try to compile the whole thing using VS,<br>
there at least I have some memories about the toolchain, but hope of<br>
course that you will be faster than me with the debugging :)<font color="#888888"><br></font></blockquote><div><br></div><div>If you set prebuilt-libraries to nil in my-config.sexp, then Lisp should theoretically build the dlls for you.
