768.0. "Multi defined errors with ELN$PSHR and CRTLOBJECT ?" by AUBER::COSTEUX (Le Plat Pays qui est le mien...) Mon Apr 28 1997 11:36

    A customer is trying to use the CLOCK_GETTIME routine and as noted in a
    Stars example I suggested him the following Compile and Link commands
    lines:
    
    $ CC/DEB/NOOPT 'p1 + ELN$:VAXELNC/LIB
    $ LINK/DEB/NOSYSLIB 'p1' + ELN$:CRTLSHARE/LIB+ -
     ELN$:PSXSHARE/LIB/INCLUDE = (ELN$PSHR) + ELN$:RTL/LIB
    
    For other aspect he links his program with also CRTLOBJECT and gets
    multi defined error on (as example) MEMSHR, MEMCMP, MEMSET (all in
    CMSC) and also ELN$PASCAL$EXIT_HANDLER in module PASCALMSC.
    
    Can somebody help ? I did not support ELN for several years and I'm a
    little bit lost ..........
    Seems that the multi definitions occur because we link togethere the 
    modules ELN$PSHR and CRTLOBJECT
    
    Thanks for help.
    
    Regards,

768.1	Can't link POSIX app against CRTLOBJECT	ZYDECO::BODA	Realtime Expertise Center	`Mon Apr 28 1997 12:29`	14
	Hi Jean-Pierre, You are correct. That's against the rules. As a reference, check section 2.1.2 of the VAXELN Guide to Using POSIX: "Unlike tradtional VAXELN programs, POSIX programs cannot be linked against the object library CRTLOBJECT." Also, I may have misunderstood your note, but you don't want to link a program against both CRTLSHARE and CRTLOBJECT. Regards, Alan

	Alright Mike! We must be on the same wavelength, down to quoting the same text! /atb

	I deleted mine. It was too spooky.

	Doubly spooky. I could have sworn that I saw a reply from you as I hit the "next unseen". Then it disappeared like a ghost :-o /atb
768.5	Here are some comments.	AUBER::COSTEUX	Le Plat Pays qui est le mien...	`Tue Apr 29 1997 05:54`	8
	Thanks all. The customer needs to link with CRTLOBJECT because his application calls INIT and Mount/Dismount devices routines included in this library. He also calls the Posix CLOCK_GETTIME routine. So is the reason why he gets these errors. Is there a solution? Jean-Pierre

	> The customer needs to link with CRTLOBJECT because his application > calls INIT and Mount/Dismount devices routines included in this > library. Hmmm, I don't think any of these would be in CRTLOBJECT. The example I'm using with clock_gettime() links correctly with psxshare, rtlshare and rtl. However, this may not work in all cases. You may need crtlshare sometime. I wonder if the /INCLUDE feature of the linker might help them avoid multiple symbols. There's a whole section on linking in the System Development Guide. There's also a whole book on linking in the VMS doc set.
