I have been trying to get the latest development snapshot (currently
6/25) to compile and link for Windows in connection with work I am doing
to produce an 0.9.8 patch introducing NetWare support to OpenSSL.
Richard addressed a number of issues I found last week (Thank you), but
I am still seeing some problems in the latest snapshot and wanted to
pass the information along to be considered for additional fixes.
Issue #1
I am still seeing a problem with the "dynamic_ctrl" function prototype
in crypto\engine\eng_dyn.c despite the change Richard made this week. It
turns out that although line 73 was changed from:
static int dynamic_ctrl(ENGINE *e, int cmd, long i, void *p, void
(*f)());
to:
static int dynamic_ctrl(ENGINE *e, int cmd, long i, void *p, void
(*f)(void));
line 319 still shows:
static int dynamic_ctrl(ENGINE *e, int cmd, long i, void *p, void
(*f)())
Since line 291 of crypto\engine\engine.h, defines:
typedef int (*ENGINE_CTRL_FUNC_PTR)(ENGINE *, int, long, void *, void
(*f)(void));
we could update line 319 of crypto\engine\eng_dyn.c to match. However,
there are several "ctrl" functions in engines code as well as they are
all defined like this one in engines\e_aep.c on line 91:
static int aep_ctrl(ENGINE *e, int cmd, long i, void *p, void (*f)());
so it looks like the best change may be to change line 73 of
crypto\engine\eng_dyn.c back from:
static int dynamic_ctrl(ENGINE *e, int cmd, long i, void *p, void
(*f)(void));
to:
static int dynamic_ctrl(ENGINE *e, int cmd, long i, void *p, void
(*f)());
and also update line 291 of crypto\engine\engine.h from:
typedef int (*ENGINE_CTRL_FUNC_PTR)(ENGINE *, int, long, void *, void
(*f)(void));
to:
typedef int (*ENGINE_CTRL_FUNC_PTR)(ENGINE *, int, long, void *, void
(*f)());
Issue #2
The .c files in the "engines" directory is not being built which
results in several undefined when linking:
link /nologo /subsystem:console /machine:I386 /opt:ref /debug
/out:out32

This can be fixed with the following patch:

--- opensslnw\util\mkfiles.pl Wed Jun 25 16:18:38 2003

With these changes the static libraries for Windows build and pass all
tests, but there are still issues with the shared libraries.
Issue #3

As near as I can tell even though these functions exist in the public
header files, none of them are defined in the actual code. The easiest
way to work around this problem is to remove the references to the
functions in util\libeay.num. This results in a number of warnings, but
the code compiles, links and tests properly. I am not sure what the
"correct" solution is.
Hope this helps.
