Subject [jira] [Reopened] (AMQCPP-417) decaf/lang/System.cpp error with HPUX aCC
Date Thu, 09 Aug 2012 14:36:19 GMT

     [ https://issues.apache.org/jira/browse/AMQCPP-417?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Jeffrey B reopened AMQCPP-417:
------------------------------


Okay, thanks, I was a little confused about that flag myself, but I asked around here and
now understand it.
When the -AA option is used with this compiler, which needs to be done, it sets the _HP_NAMESPACE_STD
flag.
So if the change can be made with just that flag, that will be good, and I think a little
better than the _HPUX_aCC flag.

Thanks.

> in the file src/main/decaf/lang/System.cpp,
> it tries to get the number of CPUS, HPUX does not have the option for sysconf() that
it uses.  I have a working addition:
> add this include at the top:
> #if defined( _HP_NAMESPACE_STD ) || !defined( _HPUX )
> 	#include <sys/mpctl.h>
> #endif
> and add this where it is getting the number of CPUs:
> #elif defined( _HP_NAMESPACE_STD ) || !defined( _HPUX )
>      	numCpus = (int)mpctl(MPC_GETNUMSPUS, NULL, NULL);
