I am trying to build ace-5.6.1 on a Redhat linux 7.3 machine. ./configure;make results in the following error:

.../../ace/OS_NS_sys_resource.inl: In function 'int ACE_OS::getrlimit(int, rlimit*)':
.../../ace/OS_NS_sys_resource.inl:24: error: invalid conversion from 'int' to '__rlimit_resource_t'

make[3]: *** [libACE_la-ACE.lo] Error 1

Any idea what might be causing this error?
