Joel has created Trac Ticket #2679 ( https://devel.rtems.org/ticket/2679) for this task. While trying to get the simulator to compile, GCC spits out the following error: In file included from /home/thedoctor/Programming/rtems/rtems/cpukit/score/include/rtems/score/threadq.h:25:0, from /home/thedoctor/Programming/rtems/rtems/cpukit/score/include/rtems/score/thread.h:35, from /home/thedoctor/Programming/rtems/rtems/cpukit/score/include/rtems/score/heap.h:22, from /home/thedoctor/Programming/rtems/rtems/cpukit/rtems/include/rtems/rtems/types.h:26, from /home/thedoctor/Programming/rtems/rtems/cpukit/rtems/include/rtems/rtems/config.h:24, from /home/thedoctor/Programming/rtems/rtems/cpukit/sapi/include/rtems/config.h:57, from ../../../rtems-schedsim/schedsim/rtems/rtems_init.c:25: /home/thedoctor/Programming/rtems/rtems/cpukit/score/include/rtems/score/rbtree.h:21:22: fatal error: sys/tree.h: No such file or directory Some scouting around reveals that the sys/tree.h header file is available in Newlib. However, I am unable to find a way to point the compiler in that direction for the scheduling simulator. Can someone please point me to the right set of Automake directives I'd require for this?There are two alternatives for missing libc files like this. 1) hope they really aren't needed and ifdef out the include. I suspect this won't work here.
That could work for a few cases, but in this case I doubt that'll help.
Is this the only solution we have? Because, I see a few new issues where newlib now has a newer version of the BSD time.h file and the schedsim fails to build without it. Currently, the only way is to copy all those header files into schedsim/rtems/sched_cpu/sys. Would it possible to extend schedsim to directly use newlib just like the RTEMS build does? Then we won't need to copy all these files around and keep duplicate copies.2) put a copy in schedsim/rtems/sched_cpu/sys. Looks like I hit other issues like a missing cpuset.h method and had to add a stub sys/lock.h.
Add a section to the instructions in the ticket. I forgot about this case. Hopefully this isn't a bad thing to fix. Since you are layering BSD capabilities on top of glibc, it can be tricky to avoid naming conflicts. --joel-- Thanking You, Darshit Shah _______________________________________________ devel mailing list devel@rtems.org http://lists.rtems.org/mailman/listinfo/devel
