Subject: Elm installation problems
Date: Wed, 6 May 87 8:49:39 PDT
Overall, I would have to rate the portablity of Elm as medium. It tries to
be portable off HP-UX/System V systems but has some basic flaws
I managed to bring it up with minor tweaks.
0) Configure does not know about Sequent
a) /dynix is name of kernel
b) build time improves by factor of 20 by using parallel make files
but others don't have that luxury.
1) Configure.sh problems on BSD systems
a) bsd test does not support -c flag
b) dirname command not found
no dirname command (at least in UCB universe)
2) Fseek problems
a) fseek (on Dynix 2.1) returns offset on sucess and -1 on error
This is similar to BSD 4.3
had to change all if(fseek(...)) to if( fseek(...) == -1)
3) Terminal problems
Padding problem on SO/SE
need to rip padding chars (digits) off front of strings
---
char *return_value_of(termcap_label)
char *termcap_label;
{
/** This will return the string kept by termcap for the
specified capability. Modified to ensure that if
tgetstr returns a pointer to a transient address
that we won't bomb out with a later segmentation
fault (thanks to Dave@Infopro for this one!)
Tweaked to remove padding sequences.
**/
register char *cp;
static char escape_sequence[20];
char *tgetstr(); /* Get termcap capability */
if (strlen(termcap_label) < 2)
return(NULL);
if (termcap_label[0] == 's' && termcap_label[1] == 'o')
cp = _setinverse;
else if (termcap_label[0] == 's' && termcap_label[1] == 'e')
cp = _clearinverse;
else if ((cp = tgetstr(termcap_label, &ptr)) == NULL)
return( (char *) NULL );
while (*cp && isascii(*cp) && isdigit(*cp))
++cp;
strcpy(escape_sequence, cp);
return (escape_sequence);
}
---
tgoto needs UP and BC (global char *)
tputs needs ospeed and PC to determine padding
4) can't handle other forms of mail file locking
BSD 4.3 (and Tektronix UTek) use flock to lock the mailbox.
should ask about location name of lockfile...

Does anyone have Elm running correctly on a VAX running 4.3bsd? The original distribution does not make and the patches to 'Makefile.mstr' posted recently don't fit in the copy of 'Makefile.mstr' included in my distribution copy. -- Rassilon

Correctly? I'm putting flock locking in so it can interact correctly with other 4.3 mailers. Other than that, yes. -- Room for growth: +==== Jim Budler ==== Advanced Micro Devices, Inc. ==== (408) 749-5806 ====+ | Compuserve: 72415,1200; Delphi: JIMBUDLER; Usenet: jimb@amdcad.AMD.COM | +=== Disclaimer: My company wouldn't let ME speak for them, would they? ===+

Jim, please post your flock patches when they're done. I was thinking about doing that here, but why duplicate effort?
