Re: configure + make fails on AIX due to missing -lpthread

[Michael Felt]

I am off to bed - but what files would you like besides config.log, Makefile for starts here.

The simple bit is configure determines that it is pthread:posix, adds the -lpthread to some Makefile arguments, but never includes those in the cc commands to create the programs.

And I shall rerun everything tomorrow. I shall add the -bnoquiet option and it shall reveal where the calls to pthread are coming from. Check in the Makefile - there are variables defined that are never used by cc to link the programs.

As to previous builds - I have not built it before. I saw it in the announcements and remember rcs as a program I used over 25 years ago. Been forced to use cvs and svm pretty much the last 10-15 years - and they have yet newer systems thought up it seems.

   After the following:
    ./configure --prefix=/opt --sysconfdir=/var/rcs/etc
   --sharedstatedir=/var/rcs/com --localstatedir=/var/rcs
   --mandir=/usr/share/man --infodir=/opt/share/info/rcs

   make proceeds normally until the programs need to 'link' -
   ident is the first failure:

Thanks for reporting this.  First questions: Was this method
used for previous versions of GNU RCS?  If not, how were
previous versions built?

   To succeed, copy/paste then add -lpthread and the command
   succeeds

I wonder where those .pthread_* symbols are being referenced.
RCS is definitely single-threaded.  Maybe something from gnulib?

   Just let me know what else you would like to receive.

Could you please re-run w/o "-lpthread", using those options
indicated in the error message "to obtain more information"?
Also, maybe nm(1) can tell where those symbols are referenced.
E.g., i'd be interested in seeing the output of:

 nm lib/*.o src/*.o src/libparts.a

(I presume AIX nm(1) works similarly to GNU/Linux nm(1); feel
free to substitute a more appropriate command as you see fit.)

Lastly, could you please also attach config.status and
lib/config.h (all from the original build, w/o "-lpthread")?
