Hello and have a good time of day! Some time ago I've posted a patch which allowed to compile and use SQLite 3.7.9 under OpenVMS operating system:
http://sqlite.1065341.n5.nabble.com/Port-of-SQLite-3-7-9-to-OpenVMS-td55734.html http://sqlite.1065341.n5.nabble.com/Port-of-SQLite-3-7-9-to-OpenVMS-patch-td55735.html Now I have a somewhat improved version of that patch, which can be used with 3.7.14.1 SQLite amalgamation. I used some tricks from http://www.vmspython.org/ version of SQLite, and invented some new. Database locking still doesn't work (use "unix-none" driver argument of sqlite3_open_v2(), or you will get a "Database is locked" message). I just cannot figure out why does SQLite POSIX advisory locking code fail to work under OpenVMS, and I plan to write a specific question to some VMS programming user group. To compile a patched sqlite3.c, use the following DCL script (mostly taken from http://www.vmspython.org/): xxxxxxxx BEGIN sqlite3vms.com $ vmsver = f$getsyi("VERSION") $ if vmsver .ges. "V8.2" $ then $ cc/opt/define=(NO_GETTOD,RTLD_GLOBAL=0,_USE_STD_STAT=1,- _LARGEFILE,_POSIX_EXIT=1) - /float=ieee/ieee=denorm - sqlite3.c $ else $ cc/opt/define=(NO_GETTOD,RTLD_GLOBAL=0, _LARGEFILE,- __USE_INO64=1,_POSIX_EXIT=1) - /float=ieee/ieee=denorm - sqlite3.c $ endif xxxxxxxx END sqlite3vms.com Best regards, Maxim Zinal P.S. And this is a patch itself: xxxxxxxx BEGIN sqlite-3.7.14.1-vms.patch diff -urb sqlite-3.7.14.1/sqlite3.c sqlite-3.7.14.1-vms/sqlite3.c --- sqlite-3.7.14.1/sqlite3.c 2012-10-04 23:49:28.000000000 +0400 +++ sqlite-3.7.14.1-vms/sqlite3.c 2012-10-31 22:48:37.391310431 +0400 @@ -71,6 +71,15 @@ #endif /* +** Under VMS, dirsync must be disabled + */ +#ifdef __VMS +# ifndef SQLITE_DISABLE_DIRSYNC +# define SQLITE_DISABLE_DIRSYNC 1 +# endif +#endif + +/* ** Include the configuration header output by 'configure' if we're using the ** autoconf-based build */ @@ -316,6 +325,10 @@ #include <inttypes.h> #endif +#ifdef __VMS +#include <unistd.h> +#endif + /* ** The following macros are used to cast pointers to integers and ** integers to pointers.
