HP aC++/HP ANSI C Release Notes (B3901-90037; A.06.26; September 2011)

4 Installation information
Read this entire document and any other release notes or readme files you may have
before you begin an installation.
To install your software, run the SD-UX swinstall command. This invokes a user
interface that will lead you through the installation.
For more information about installation procedures and related issues, refer Managing
HP-UX Software with SD-UX and other README, installation, and upgrade documentation
provided or described in your HP-UX 11.x operating system package.
Depending on your environment, you may also need documentation for other parts of
your system, such as networking, system security, and windowing.
Hardware requirements
IMPORTANT: Compiling files at optimization level 2 (-O or +O2) and above increases
the amount of virtual memory needed by the compiler. In cases where very large functions
or files are compiled at +O2, or in cases where aggressive (+O3 and above) optimization
is used, ensure that the maxdsiz kernel tunable is set appropriately on the machine
where compilation takes place.
HP recommends a setting of 0x100000000, or 4 GB (the default for this parameter is
0x100000000, or 4 GB) for "maxdsiz_64bit" in such cases. Updating the
"maxdsiz_64bit" tunable will ensure that the compiler does not run out of virtual
memory when compiling large files or functions.
In addition, "maxssiz_64bit" should be set to 128 MB for very large or complex
input files. (Normally a "maxssiz_64bit" setting of 64 MB will be sufficient.)
HP recommends not reducing the maxfiles setting below the default value of 2048.
See the kctune man page for more information on how to change kernel tunable
parameters.
HP aC++ requires approximately 150 MB for the files in
/opt/aCC
The other components require approximately:
40 MB for WDB
110 MB for u2comp/be
95 MB for HP Caliper
205 MB for HP Code Advisor
For more precise sizes, use the command:
/usr/sbin/swlist -a size B9007AA
