Hi Elliott, Jan
ok, I had a setup in which I have only BDB 4.7.25 on the laptop, no
more CFFI and only the newest UFFI. The my-config.sexp states "4.7" as
a version and I removed all the constants from previous BDB versions
in the bberkeley-constants.lisp as well as all existing FASLs.I use
Elliott's DLLs. Same effect - "Invalid argument" in all places
described earlier.
What I checked until now are the FLAGS-encodings - they are correct,
the constants also for the 4.7 version. Which means that the problem
is not a version or a 32/64-bit issue but something on the
UFFI/DLL/BDB-chain....
Elliot, if you give me a script to compile the DLLs with GCC (I have
the memutil one, but not the libberkeley-db.dll and following what is
wirttten in the .ASD file doesn't produce for me the DLLs), I could
start learning the GDB to try to see what happens on the C-side in the
spare free time. Or I could try to compile the whole thing using VS,
there at least I have some memories about the toolchain, but hope of
course that you will be faster than me with the debugging :)
