I'm trying to build RTEMS (www.rtems.org) for my MicroBlaze processor, but I have an error that I can't fix.

When using autoconf, the file conftest.c is generated and requires function creat() in libc. But, libc does not have the function creat(), so it fails with an error.

Does anyone knows why this function is missing, and how can I fix it ?

  • creat() used to exist but is now [obsoleted](http://www.gnu.org/software/libc/manual/html_node/Opening-and-Closing-Files.html) Are you using an old version of RTEMS? In my memories RTEMS leader Joel Sherrill used to be part of GCC steering committee. GCC is not libc, but still... – jbm Sep 11 '15 at 11:17
  • I use version 4.10.99.0 (because I need a BSP for the Microblaze processor, and I found this repository : https://github.com/heshamelmatary/rtems-microblaze) Do you think it's a too old one ? And have you a solution to add creat() to libc ? – DimitriTuaz Sep 11 '15 at 11:34
  • Well, last commit is 8 month old, but I would not consider this "old" by RTEMS pace. Of course you installed a RTEMS toolchain (including a libc) that suit your target, check if it has a creat(), and a functionnal one: I an able to use a creat() in dummy code using my host toolchain, but it always yeld an error. In any case, you'd better ask in the rtems mailing list. It's a small but knowledgeable community. Here on SO, only 29 questions tagged "rtems"... – jbm Sep 11 '15 at 12:04
  • I installed a RTEMS toolchain (including a libc) that suit my target, but it has not creat()... I already asked in the rtems mailing list, and waiting for an answer, but I also tried on SO :) – DimitriTuaz Sep 11 '15 at 12:17
