HELP! I'm not proficient in C (in reality I can just barely spell it).
I un-shared all the files in the postings for ARC and typed 'make'.
It was lovely to see all that compiling going on so nicely. However,
when it got to the link (?) process (you know - the 'cc -o arc' followed
by all the '.o' files) it finished up with
Undefined:
_memset
*** Exit 1
. Now I'm pretty sure that it wants
some module or routine called 'memset' in the program 'arcext.c'.
I can't find this thing anywhere. I'm on a Pyramid system using BSD4
point something Unix. Someone please tell me where to find this module
and how to properly get it into the source.
Thanks,
Terry Banks

At our installation we are running UNIX BSD 4.2 and 4.3 on a Sun and VAX 11/750 respectively and both versions seem to have this routine in libc.a. Here is what memset does (as quoted from the manual page): char *memset(s,c,n) char *s; int c,n; memset sets the first 'n' characters in memory area 's' to the value of character 'c'. It returns 's'. There are two solutions to your problem: 1) Consult your local guru to see if you have memset or a similar routine in one of the system libraries (Sorry, but I'm not familiar with Pyramid). 2) Write your own little memset module (similar to the one below) in C and link it to all of the files which appear to be using it in the code. From what I have observed, arclzw.c, arcmisc.c, arcsqs.c are declaring the routine, but arcext.c is the only one that is actually calling it. Good luck 8-). char *memset(s,c,n) char *s; int c,n; { register char *t; t = s while (n--) *t++ = c; return(s); } Edward Dergharapetian (213) 206-6067 UCLA Mathematics Department. 9407A Boelter Hall. 405 Hilgard Ave. Los Angeles, CA 90024-1555 UUCP:...!{ihnp4,ucbvax,sdcrdcf,{hao!cepu}}!ucla-cs!math.ucla.edu!edward ARPA: edward@math.ucla.edu BITNET: edward%math.ucla.edu@INTERBIT

Here is what memset does >(as quoted from the manual page): Actually, it is a part of the AT&T libc.a. True BSD probably has it (you say it does, so I'll believe you). >There are two solutions to your problem: 1) Consult your local guru to >see if you have memset or a similar routine in one of the system libraries >(Sorry, but I'm not familiar with Pyramid). Well, here's the good news. On a Pyramid, seeing as it has both the BSD and AT&T C libraries (along with most everything else), this is quite easy to overcome. Simply do the following: Instead of using 'cc' (the Berkeley side's cc), use the AT&T side's cc (i.e. 'att cc'). att cc -o arc ...................... Or, you can simply include the AT&T side's C library by appending the following flag on your compile: -l/.attlib/libc.a i.e. cc -o arc ......... -l/.attlib/libc.a Either one of these solutions should work (I just tried them both on our Pyramid). Hope this helps. Good luck. ------------------------------------------------------------------------------- | Steve DeJarnett | ...!ihnp4!csun!polyslo!steve | | Computer Systems Lab | ...!{csustan,csun,sdsu}!polyslo!steve | | Cal Poly State Univ. | ...!ucbvax!voder!polyslo!steve | | San Luis Obispo, CA 93407 | | ------------------------------------------------------------------------------- #include <std_disclaimer.h>

I was thinking of another program when I wrote this (oooooopps). Anyway, I just tried it, so here is the PROPER way (or at least the one that works) to do it: cc -o arc ........... libtws.a /.attlib/libc.a ^^^^^^^^^^^^^^^ Add this part to the end of your compile. > Or, you can simply include the AT&T side's C library by appending >the following flag on your compile: > > -l/.attlib/libc.a Whoa. Wrong. Won't work. Do it as shown above. Next time I have to learn to proofread my postings first. > Either one of these solutions should work (I just tried them both >on our Pyramid). Correction, I tried similar things, but on a different program. Just can't keep those darn compiler flags straight in my head on a Friday afternoon :-). Sorry about the screwup. The above-mentioned way REALLY DOES WORK. I honestly just tried it with the latest version of ARC. ------------------------------------------------------------------------------- | Steve DeJarnett | steve@polyslo.UUCP | | Computer Systems Lab | ...!{csustan,csun,sdsu}!polyslo!steve | | Cal Poly State Univ. | ...!ucbvax!voder!polyslo!steve | | San Luis Obispo, CA 93407 | | ------------------------------------------------------------------------------- #include <std_disclaimer.h>
