List of Compiler Options and Their Defaults
Options that Specify Compiler Characteristics
| Option Type | Default Value | #pragma options | C | C++ |
| -flag | - | - | x | x |
Syntax
-Fconfig_file:stanza | -Fconfig_file | -F:stanza
Purpose
Names an alternative configuration file for xlC.
Notes
| config_file | Specifies the configuration of your system to the compiler. |
| stanza | Is the name of the command used to
invoke the compiler. This directs the compiler to the
config_file under stanza for the description of the
compiler environment. This suboption is not required. |
The default is a configuration file supplied at installation time called /etc/ibmcxx.cfg. Any file names or stanzas that you specify on the command line or within your source file override the defaults specified in the /etc/ibmcxx.cfg configuration file.
For information regarding the contents of the configuration file, refer to Specifying Options in the Configuration File.
Options specified with -W option override options in the -Fconfig_file configuration file. The -B, -t, and -W options override the -F option.
Example
To compile myprogram.c using a configuration file /usr/tmp/myibmcxx.cfg
with an xlC stanza, enter:
xlC myprogram.c -F/usr/tmp/myibmcxx.cfg:xlC
