[[b2.reference.tools.compiler.acc]]
= HP aC++ compiler

The `acc` module supports the
http://h21007.www2.hp.com/dspp/tech/tech_TechSoftwareDetailPage_IDX/1,1703,1740,00.html[HP
aC++ compiler] for the HP-UX operating system.

The module is initialized using the following syntax:

----
using acc : [version] : [c++-compile-command] : [compiler options] ;
----

This statement may be repeated several times, if you want to configure
several versions of the compiler.

If the command is not specified, the `aCC` binary will be searched in
PATH.


The following options can be provided, using
_`<option-name>option-value syntax`_:

`cflags`::
Specifies additional compiler flags that will be used when compiling C
sources.

`cxxflags`::
Specifies additional compiler flags that will be used when compiling C++
sources.

`compileflags`::
Specifies additional compiler flags that will be used when compiling both C
and C++ sources.

`linkflags`::
Specifies additional command line options that will be passed to the linker.
