aCC_FULL_PATHNAMES Environment Variable
Exporting the aCC_FULL_PATHNAMES variable causes the compiler to include full path names for
files in compiler messages. This feature is useful in debugging.
aCC_MAXERR Environment Variable
The aCC_MAXERR environment variable allows you to set the maximum number of errors you want
the compiler to report before it terminates compilation. The default is 100.
CXXOPTS Environment Variable
The CXXOPTS environment variable provides a convenient way to include frequently used
command-line options automatically.
Options before the vertical bar (|) are placed before command-line options to aCC. The options
after the vertical bar are placed after any command-line option. Note that the vertical bar must be
delimited by white space.
If you do not use the vertical bar, all options are placed before the command line parameters. Set
the environment variable and the options you want are automatically included each time you
execute the aCC command.
Syntax:
export CXXOPTS="options | options" ksh/sh notation
setenv CXXOPTS "options | options" csh notation
Usage:
For quick or temporary changes to your build environment, use CXXOPTS instead of editing your
makefiles.
Example:
export CXXOPTS="-v | -lm" ksh/sh notation
setenv CXXOPTS "-v | -lm" csh notation
The above command causes the -v and -l options to be passed to the aCC command each time
you execute it.
When CXXOPTS is set as above, the following two commands are equivalent:
aCC -g prog.C
aCC -v -g prog.C -lm
CCLIBDIR Environment Variable
The CCLIBDIR environment variable causes the aCC command to search for libraries in an alternate
directory before searching in the default directories.
Syntax:
export CCLIBDIR=directory ksh/sh notation
setenv CCLIBDIR directory csh notation
directory is an HP-UX directory where you want HP aC++ to look for libraries.
Example:
export CCLIBDIR=/mnt/proj/lib
In this example HP aC++ searches the directory /mnt/proj/lib for libraries before searching
the directory /opt/aCC/lib.
