[Q] can't resolve symbol '__getcwd' error in arla 0.20 and 0.21

[Takashi Ichihara]

  Hi all

  It seems that in some enviromnents, the getpwd (libgetcwd.so.0.21 
or getcwd.so in arla 0.20) seems to have a problem. This problem 
occurs in the arla version 0.21 and 0.20 and there is no problem 
in the previous version (arla-0.19, 0.18, 0.17.1, I have checked)

   I have two different environments of "Linux Kernel 2.2.0 + 
Arla 0.21".  One (Enviromnent 1) has this problem and the other 
(Environment 2) does not have this problem.  

Does anyone has any idea ?   

--------------
Environment 1
--------------
 
  Dual Pentium II 450 MHz, 256 MB Memory, IDE 4G HD 
  Redhat 5.1 + several upgrade softwares installed
  Kernel 2.2.0 (SMP support option)
  arla   0.21  (libgetcwd.so.0.21 pre-load)
  uname -a : Linux xxxxx.rrrrr.bnl.gov 2.2.0 #1 SMP Tue Jan 26 21:30:30 
             EST 1999 i686 unknow

 Problem
 -------

  The pgf77 (PGI fortran) and f77 (Absoft fortran) does not work when 
libgetcwd.so.0 is pre-loaded (error - can't resolve symbol '__getcwd),
while g77 (GNU F77) still works.

  csh> pgf77 sim,f                             (PGI fortran : NG)
  pgf77: can't resolve symbol '__getcwd' 

  csh> f77 sim.f                               (Absoft fortran: NG)
  f77fe: can't resolve symbol '__getcwd'
  /usr/bin/f77: sim.int: No such file or directory
                                      				      
  csh> g77 sim.f                      	       (GNU fortran: ok)
  csh>       

 o When the libgetcwd.so.0 (getcwd.so) is not pre-loaded, both the 
   pgf77, f77, and g77 works fine.  (But pwd of csh or tcsh does not 
   work under /afs directory)  

 o alra-0.17.1 + kernel 2.2.0 DOES NOT have this problem. This works.
 o arla-0.18   + kernel 2.2.0 DOES NOT have this problem. This works.
 o arla-0.19   + kernel 2.2.0 DOES NOT have this problem. This works.
 o arla-0.20   + Kernel 2.2.0 has this problem. 

  Therefore, this problem of  "can't resolve symbol '__getcwd' " seems 
to be introduced in arla-0.20 and also continues to arla-0.21.

-----------------
Environment (2)
-----------------

  Pentium pro 200 MHz, single CPU, 128 MB Memory,  IDE 4GB HD
  Redhat 5.2 installed
  kernel 2.2.0 (not SMP supported)
  arla   0.21  (libgetcwd.so.0.21 pre-load)
  uname -a : Linux xxxxxx.riken.go.jp 2.2.0 #1 Wed Jan 27 10:36:09 JST 
             1999 i686 unknown

  csh> pgf77 sim.f				(pgi f77 ok)
       Linking:

  csh> f77 sim.f                                (Absoft f77 ok)
  FORTRAN 77 Compiler 4.4, Copyright (c) 1987-1997, Absoft Corp.
  csh>

  csh> g77 sim.f				(gnu f77 ok)
  csh>

  There seems to be of no problem of "Kernel 2.2 + arla 0.21(getcwd.so 
pre-loaded)"  on this environment (single CPU kernel and RH5.2-base)
for pgf77, f77 and g777.  Kernel 2.2.0 +arla 0.20 also works well 
without problem.

----------------

The prime differences between these two environments are

    o  SMP support kernel (2.2.0) (1) or no SMP kernel (2.2.0) (1)
    o  RH 5.1 based (1) or RH 5.2 based (2)

Thank you for any suggestions.
