  1. 15.7.1993
    2. 

  2. xntp3 compiles now again on AIX. I have disabled prototyping and added
    3. 

  3. the switch -D_NO_PROTO which disables prototyping in the system include
    4. 

  4. files.

  8. Xntp version 3 now support the cc compiler for AIX.
    9. 

  9. The Config.aix will now use cc by default.  You can still compile xntp
    10. 

  10. with the bsd compiler by changing "COMP= cc" to "COMP= bsdcc" and
    11. 

  11. and removing the "-DSTUPID_SIGNAL" option from the "DEFS" option.
    12. 

  12. 

  13. xntp and tickadj was also modified  so that the value of tickadj is read
    14. 

  14. form the kernel and can be set by tickadj.  For now I would not set 
    15. 

  15. tickadj below 40 us.

  21. This is a modified version of xntp version 3 for the RS6000. It works for
    22. 

  22. AIX 3.2 and these are the same changes as have been applied tothe version 2
    23. 

  23. implementation of xntp. It works fine for us but I have not tested all of
    24. 

  24. the features, especially the local clock support for the RS6000 is not tested
    25. 

  25. at all.

  33. A hacked version of xntp for the IBM RS/6000 under AIX 3.1 can be found
    34. 

  34. in xntp.rs6000.tar.Z. [ if still available at all - Frank Kardel 93/12/3 ]
    35. 

  35. 

  36. This will not work on older versions of AIX due to a kernel bug;  to find
    37. 

  37. out whether you have the kernel bug, compile and run testrs6000.c (see
    38. 

  38. comments in the code for instructions).
    39. 

  39. 

  40. xntp and testrs6000 require "bsdcc" to compile.  This is simply another
    41. 

  41. entry point into the xlc compiler with various options set for BSD
    42. 

  42. compatibility.  If your system does not have bsdcc, do the following:
    43. 

  43. 

  44. link /bin/bsdcc to /bin/xlc
    45. 

  45. 

  46. put the following into /etc/xlc.cfg:
    47.

  48. * BSD compatibility
    49. 

  49. bsdcc:  use        = DEFLT
