Hi,
Some poking in the .\NetWare Makefile found:
> # uncomment this to enable the experimental PerlIO I/O subsystem
> # else USE_STDIO will be defined.
> #USE_PERLIO = define
so gave USE_PERLIO a try on a NetWare LibC build. There were a number of
compiler errors but will FTM constrain interest to two;
1. In perlio.c there are two (what I think are global) vars:
> PL_perlio_fd_refcnt_size
> PL_perlio_fd_refcnt
and just above their use is a comment (2327):
> /* PL_perlio_fd_refcnt[] is in intrpvar.h */
If it is then it is behind a bush I didn't see.
In a patch supplied by a Novell dev was added (above the comment):
> +#ifdef NETWARE
> +#define PERLIO_MAX_REFCOUNTABLE_FD 2048;
> +PL_perlio_fd_refcnt_size = PERLIO_MAX_REFCOUNTABLE_FD;
> +int PL_perlio_fd_refcnt[PERLIO_MAX_REFCOUNTABLE_FD] = {0};
> +#endif
Using more 'recent' :-) source and digging I calmed down the compiler on
these lines with:
> #ifdef NETWARE
> #define PERLIO_MAX_REFCOUNTABLE_FD 2048
> int PL_perlio_fd_refcnt_size = PERLIO_MAX_REFCOUNTABLE_FD;
> int netware_fds[PERLIO_MAX_REFCOUNTABLE_FD] = {0};
> int * PL_perlio_fd_refcnt = &netware_fds;
> #endif
which suggests these two vars aren't actually set elsewhere. Alas other
errors have so far prevented linking Libperl.nlm to see if there are
symbol clashes when combined. Can someone comment on the status of these
2 vars please?
2. In pp_sys.c there are a two places with a block like:
> #ifdef EPOC
> setbuf( IoIFP(io), NULL); /* EPOC gets confused about sockets */
> #endif
Novell patches expanded the EPOC define to include NetWare, and as my
Perl 5.8.9 worked okay, I will assume they are correct.
Under PerlIO setbuf(a,b) becomes a No-Go (as do a lot of functions) and
was wondering if that might also mean PerlIO is a No-Go for both EPOC
AND NetWare? (Most of the remaining errors are related to the renamed
functions...)
TIA,
Norm
