  39  
  40  Perl 5.7/8.x for DG/UX ix86 R4.20MU0x
  41  
  42  =head1 BUILDING PERL ON DG/UX
  43  
  44  =head2 Non-threaded Perl on DG/UX
  45  
  46  Just run ./Configure script from the top directory.
  47  Then give "make" to compile.
  48  
  49  =head2 Threaded Perl on DG/UX
  50  
  51  If you are using as compiler GCC-2.95.x rev(DG/UX)
  52  an easy solution for configuring perl in your DG/UX
  53  machine is to run the command:
  54  
  55  ./Configure -Dusethreads -Duseithreads -Dusedevel -des
  56  
  57  This will automatically accept all the defaults and
  58  in particular /usr/local/ as installation directory.
  59  Note that GCC-2.95.x rev(DG/UX) knows the switch
  60  -pthread which allows it to link correctly DG/UX's
  61  -lthread library.
  62  
  63  If you want to change the installation directory or
  64  have a standard DG/UX with C compiler GCC-2.7.2.x
  65  then you have no choice than to do an interactive
  66  build by issuing the command:
  67  
  68  ./Configure -Dusethreads -Duseithreads
  69  
  70  In particular with GCC-2.7.2.x accept all the defaults
  71  and *watch* out for the message:
  72  
  73      Any additional ld flags (NOT including libraries)? [ -pthread]
  74  
  75  Instead of -pthread put here -lthread. CGCC-2.7.2.x
  76  that comes with the DG/UX OS does NOT know the -pthread
  77  switch. So your build will fail if you choose the defaults.
  78  After configuration is done correctly give "make" to compile.
  79  
  80  =head2 Testing Perl on DG/UX
  81  
  82  Issuing a "make test" will run all the tests. 
  83  If the test lib/ftmp-security gives you as a result
  84  something like
  85  
  86      lib/ftmp-security....File::Temp::_gettemp:
  87      Parent directory (/tmp/) is not safe (sticky bit not set
  88      when world writable?) at lib/ftmp-security.t line 100
  89  
  90  don't panic and just set the sticky bit in your /tmp
  91  directory by doing the following as root:
  92  
  93  cd /
  94  chmod +t /tmp (=set the sticky bit to /tmp).
  95  
  96  Then rerun the tests. This time all must be OK.
  97  
  98  =head2 Installing the built perl on DG/UX
  99  
 100  Run the command "make install"
