Chapter 9. Using Environment Variables
there are still some dependencies on the PGI environment variable, and you can use it as a convenience when
initializing your environment for use of the PGI compilers and tools.
For example, assuming you use csh and want the 64-bit linux86-64 versions of the PGI compilers and tools to
be the default, you would use this syntax:
%
%
%
%
setenv PGI /usr/pgi
setenv MANPATH "$MANPATH":$PGI/linux86/8.0/man
setenv LM_LICENSE_FILE $PGI/license.dat
set path = ($PGI/linux86-64/8.0/bin $path)
PGI_CONTINUE
You set the PGI_CONTINUE variable to specify the actions to take before continuing with execution.
For example, if the PGI_CONTINUE environment variable is set and then a program that is compiled
with –Mchkfpstk is executed, the stack is automatically cleaned up and execution then continues. If
PGI_CONTINUE is set to verbose, the stack is automatically cleaned up, a warning message is printed, and
then execution continues.
Note
There is a performance penalty associated with the stack cleanup.
PGI_OBJSUFFIX
You can set the PGI_OBJSUFFIX environment variable to generate object files that have a specific suffix. For
example, if you set PGI_OBJSUFFIX to .o, the object files have a suffix of .o rather than .obj.
PGI_STACK_USAGE
(Windows only) The PGI_STACK_USAGE variable allows you to explicitly set stack properties for your
program. When the user compiles a program with the –Mchkstk option and sets the PGI_STACK_USAGE
environment variable to any value, the program displays the stack space allocated and used after the program
exits. You might see something similar to the following message:
thread 0 stack: max 8180KB, used 48KB
This message indicates that the program used 48KB of a 8180KB allocated stack. For more information on the
–Mchkstk option, refer to –Mchkstk.
PGI_TERM
The PGI_TERM environment variable controls the stack traceback and just-in-time debugging functionality.
The runtime libraries use the value of PGI_TERM to determine what action to take when a program
abnormally terminates.
The value of PGI_TERM is a comma-separated list of options. The commands for setting the environment
variable follow.
• In csh:
% setenv PGI_TERM option[,option...]
