Re: [foxboro] cc compiler library linking errors


Hi Chuck,

  Try adding the -lposix4
  This is all I have to do for my latest program - IA version 6.1

cc X.c -o X -lfox -lposix4

  I am not doing anything fancy either .  .  .

Subject: [foxboro] cc compiler library linking errors


Are there any C programmers still out there?  I'm having trouble with the
Fox libraries when I compile my program.  I use the form:

cc filename.c -o filename -lfox -lnsl -lsocket

The program gathers bits of information from several blocks and prints the
data out in a report.  All I needed to do was to add one more line
containing one more number to the report.  The C code was embarrassingly
simple and I'm certain that it is not the code, especially since the error
messages tell me so:  

Undefined symbol                first referenced in file
timer_create            /usr/lib/libfox.so
sigwaitinfo                     /usr/lib/libfox.so
timer_settime           /usr/lib/libfox.so
ld: fatal: Symbol referencing errors. No output written

The file -- libfox.so -- is an ELF 32-bit MSB dynamic lib SPARC Version 1,
etc  -- according to the file command.  So, I can't just scan through it for
clues using the vi editor. 

Really, I've done this before.  It's just that I can't recall doing it since
the update to the operating system back in late 1999 (remember the Y2K
hoax?).  I'm open to suggestion from anyone familiar with this type of
scenario.  My current guess is that some of the subsequent library files
have been moved from their former locations.
