.Sh "Non-threaded Perl on \s-1DG/UX\s0"
.IX Subsection "Non-threaded Perl on DG/UX"
Just run ./Configure script from the top directory.
Then give \*(L"make\*(R" to compile.
.Sh "Threaded Perl on \s-1DG/UX\s0"
.IX Subsection "Threaded Perl on DG/UX"
If you are using as compiler \s-1GCC\-2\s0.95.x rev(\s-1DG/UX\s0)
an easy solution for configuring perl in your \s-1DG/UX\s0
machine is to run the command:
.PP
\&./Configure \-Dusethreads \-Duseithreads \-Dusedevel \-des
.PP
This will automatically accept all the defaults and
in particular /usr/local/ as installation directory.
Note that \s-1GCC\-2\s0.95.x rev(\s-1DG/UX\s0) knows the switch
\&\-pthread which allows it to link correctly \s-1DG/UX\s0's
\&\-lthread library.
.PP
If you want to change the installation directory or
have a standard \s-1DG/UX\s0 with C compiler \s-1GCC\-2\s0.7.2.x
then you have no choice than to do an interactive
build by issuing the command:
.PP
\&./Configure \-Dusethreads \-Duseithreads
.PP
In particular with \s-1GCC\-2\s0.7.2.x accept all the defaults
and *watch* out for the message:
.PP
.Vb 1
\&    Any additional ld flags (NOT including libraries)? [ \-pthread]
.Ve
.PP
Instead of \-pthread put here \-lthread. \s-1CGCC\-2\s0.7.2.x
that comes with the \s-1DG/UX\s0 \s-1OS\s0 does \s-1NOT\s0 know the \-pthread
switch. So your build will fail if you choose the defaults.
After configuration is done correctly give \*(L"make\*(R" to compile.
.Sh "Testing Perl on \s-1DG/UX\s0"
.IX Subsection "Testing Perl on DG/UX"
Issuing a \*(L"make test\*(R" will run all the tests. 
If the test lib/ftmp\-security gives you as a result
something like
.PP
.Vb 3
\&    lib/ftmp\-security....File::Temp::_gettemp:
\&    Parent directory (/tmp/) is not safe (sticky bit not set
\&    when world writable?) at lib/ftmp\-security.t line 100
.Ve
.PP
don't panic and just set the sticky bit in your /tmp
directory by doing the following as root:
.PP
cd /
chmod +t /tmp (=set the sticky bit to /tmp).
.PP
Then rerun the tests. This time all must be \s-1OK\s0.
