Hello, > I seem to have 1.0.0d builds working on VMS
Great news, I would be happy to try the build with your changes. Could you please send some instructions where the patch can be found? Or it would be the best to post the diffs here, making available for Richard to merge into the code. Thank you, Steven. Best regards, Z -----Original Message----- From: Steven M.

I need a macro/typedef for an integer with the same size as a pointer. On non-VMS systems "intptr_t" might be suitable, but not on VMS, so it appears to me that some new OpenSSL-specific thing must be added. I can get it defined appropriately on VMS. Elsewhere, I don't care; "size_t" (as is used now), "intptr_t", whatever. But I'd be happier (others, too, I'd guess) if someone else chose the name, placement, and other details. I've identified two places where use of "size_t" caused problems on VMS with 64-bit pointers, "crypto/bn/bn_mont.c" and "crypto/bn/bn_nist.c". It might be wise to scan the code for other inappropriate uses of "size_t", as I haven't done that. 2. The argv-using "apps/*.c" programs need reform to use "argc" instead of looking for a NULL terminator at the end of "argv[]". (Looking for a NULL makes sense for "envp[]", which is expected to be NULL-terminated, but not so much for "argv[]", where it causes bad behavior on VMS Alpha with 64-bit pointers, and where "argc" is obviously available and suitable.) I've converted "apps/cms.c" and "apps/smime.c", because those were causing test failures. My current scheme changes code like this: [...] int MAIN(int argc, char **argv) [...] char **args; [...] args = argv + 1; [...] while (*args) [or similar] [...] args++; [...] to code like this: [...] int MAIN(int argc, char **argv) [...] int argi; char **args; [...] argi = 1; args = &argv[argi])[0]; [...] while (argi < argc) [or similar] [...] args = &argv[++argi]; [...] The maintainer(s) may prefer some other scheme/details, so I'm reluctant to fiddle with the other, similar programs in that collection until someone higher up nods, or complains, or something. (Also, I wouldn't bet that any other of those programs gets tested on VMS, so there's probably some risk in my making the changes to them.) For the ones I have changed, I can supply patches or whole replacement files, if anyone is interested. If some decision maker can settle these pending items, then I can pack this batch of changes into a form which might be more easily adopted into the main code base. Other changes: I've added a C macro, OPENSSL_NO_SETVBUF_IONBF, which is defined only on VMS, and which is used to bracket instances of "setvbuf(..., _IONBF, ...)". On VMS, this use of setvbuf() is unsupported, and is incompatible with 64-bit pointers. Everyone else can ignore this new macro, and get the same behavior as before. I've modified the VMS builders to allow the user to specify a path to a zlib object library (expecting "zlib.h" to be in the same directory). I've also done some tidying in the VMS builders (typography, lame code reduction, ...). I've added a new VMS-specific header file, "crypto/vms_rms.h" to reduce the code clutter involved with NAM versus NAML (RMS file name) structures (in "crypto/LPdir_vms.c" and "crypto/dso/dso_vms.c"). I use essentially similar stuff in many other projects. You're welcome to it. (I haven't added a copyright heading.) ------------------------------------------------------------------------ Steven M.
