[PPL-devel] setitimer functions

[Roy Sfaradi]

Hello Roberto,

Thanks for your reply.

I've tried the --disable-watchdog (and --without-watchdog) option. The configure executed without errors, but, when I tried make I got the following error:
------
timings.cc: In function `void start_clock()':
timings.cc:50: error: aggregate `rusage rsg' has incomplete type and cannot be defined
timings.cc:51: error: `RUSAGE_SELF' undeclared (first use this function)
timings.cc:51: error: (Each undeclared identifier is reported only once for each function it appears in.)
timings.cc:51: error: `getrusage' undeclared (first use this function)
timings.cc: In function `void print_clock(std::ostream&)':
timings.cc:61: error: aggregate `rusage rsg' has incomplete type and cannot be defined
timings.cc:62: error: `RUSAGE_SELF' undeclared (first use this function)
timings.cc:62: error: `getrusage' undeclared (first use this function)
make[2]: *** [timings.o] Error 1
make[1]: *** [all-recursive] Error 1
make: *** [all] Error 2
------

I guess this error is for similar reason...

Dear Ro'ee,

one possibility is to use Cygwin.  Another possibility, if you do not need the functionalities
provided by the Parma Watchdog Library, is to configure the PPL with the option --disable-watchdog.
All the best,

     Roberto
