<p>Hallo Mritunjay,</p>
<p>You can't just take the github ptpd sources and make them work in RTEMS. You have to make some configuration<br />and sources changes before you can build the with the rsb.</p>
<p>Some things like the sys/cpuset.h seems not to be fully compatible yet and so the configure simply makes<br />"wrong" decisions. E.g. defines HAVE_SYS_CPUSET_H = 1 as sys/cpuset.h exists.I played a little bit with it and reset<br />the definition in ptpd-master/src/ptpd.h (quick and dirty) and could reduce the error messages because there is a query for<br />this variable in the code (src/dep/sys.c):</p>
<p>in ptpd.h after the include of the created configs :</p>
<p>...<br />#ifdef HAVE_CONFIG_H<br /># include <config.h><br />#endif /* HAVE_CONFIG_H */</p>
<p>#undef HAVE_NTP_GETTIME<br />#undef HAVE_SYS_CPUSET_H</p>
<p>#ifdef linux<br />...</p>
<p>in src/dep/sys.c </p>
<p>...<br /><span>#ifdef HAVE_SYS_CPUSET_H <br /> cpuset_t mask; <br /> CPU_ZERO(&mask); <br /> if(cpu >= 0) { <br /> CPU_SET(cpu,&mask); <br /> } else { <br /> int i; <br /> for(i = 0; i < CPU_SETSIZE; i++) { <br /> CPU_SET(i, &mask); <br /> } <br /> } <br /> return(cpuset_setaffinity(CPU_LEVEL_WHICH, CPU_WHICH_PID, <br /> -1, sizeof(mask), &mask)); <br />#endif /* HAVE_SYS_CPUSET_H */ <br /></span></p>
<p>In src/dep/constants_dep.h one can find:</p>
<p>* platform dependent */</p>
<p>#if !defined(linux) && !defined(__NetBSD__) && !defined(__FreeBSD__) && \<br />!defined(__APPLE__) && !defined(__OpenBSD__) && !defined(__sun) && !defined(__QNXNTO__)<br />#error PTPD hasn't been ported to this OS - should be possible \<br />if it's POSIX compatible, if you succeed, report it to ptpd-devel@sourceforge.net<br />#endif</p>
<p>here I added "&& !defined(__rtems__) </p>
<p>and here:<br /><span style="font-size: 10pt;">... <br /></span><span>#if defined(__NetBSD__) || defined(__FreeBSD__) || defined(__APPLE__) || defined(__OpenBSD__) || defined(__sun) || defined(__QNXNTO__) || defined(__rtems__) <br /># include <sys/types.h> <br /># include <sys/socket.h> <br />#ifdef HAVE_SYS_SOCKIO_H <br />#include <sys/sockio.h> <br />#endif /* HAVE_SYS_SOCKIO_H */ <br /># include <netinet/in.h> <br /># include <net/if.h> <br /># include <net/if_dl.h> <br /># include <net/if_types.h> <br />#ifdef HAVE_NET_IF_ETHER_H <br /># include <net/if_ether.h><br />...</span></p>
<p><span>and so on... You'd have to bite through it once and then you will surely get it compiled. <br /></span></p>
<p>HTH Heinz</p>

<div>Please it would be kind of you all to guide on what is the best thing I can do next. It is looking</div>
<div>a little difficult. If something similar has been done earlier, sharing it can be a lot helpful to take a cue. </div>
