a83b6f46 42=head1 BUILDING PERL ON DG/UX
8e9464f1 43
a83b6f46 44=head2 Non-threaded Perl on DG/UX
8e9464f1 45
46Just run ./Configure script from the top directory.
47Then give "make" to compile.
48
a83b6f46 49=head2 Threaded Perl on DG/UX
8e9464f1 50
51If you are using as compiler GCC-2.95.x rev(DG/UX)
52an easy solution for configuring perl in your DG/UX
53machine is to run the command:
54
55./Configure -Dusethreads -Duse5005threads -des
56
57This will automatically accept all the defaults and
58in particular /usr/local/ as installation directory.
59Note that GCC-2.95.x rev(DG/UX) knows the switch
210b36aa 60-pthread which allows it to link correctly DG/UX's
8e9464f1 61-lthread library.
d8139a88 62
210b36aa 63If you want to change the installation directory or
8e9464f1 64have a standard DG/UX with C compiler GCC-2.7.2.x
65then you have no choice than to do an interactive
66build by issuing the command:
67
68./Configure -Dusethreads -Duse5005threads
69
70In particular with GCC-2.7.2.x accept all the defaults
71and *watch* out for the message:
72
d8139a88 73 Any additional ld flags (NOT including libraries)? [ -pthread]
8e9464f1 74
75Instead of -pthread put here -lthread. CGCC-2.7.2.x
76that comes with the DG/UX OS does NOT know the -pthread
77switch. So your build will fail if you choose the defaults.
78After configuration is done correctly give "make" to compile.
79
a83b6f46 80=head2 Testing Perl on DG/UX
8e9464f1 81
82Issuing a "make test" will run all the tests.
83If the test lib/ftmp-security gives you as a result
84something like
85
d8139a88 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
8e9464f1 89
90don't panic and just set the sticky bit in your /tmp
91directory by doing the following as root:
92
93cd /
94chmod +t /tmp (=set the sticky bit to /tmp).
95
96Then rerun the tests. This time all must be OK.
97
a83b6f46 98=head2 Installing the built perl on DG/UX
8e9464f1 99
100Run the command "make install"
