SYNOPSIS
One can read this document in the following formats:

to list some (not all may be available simultaneously), or it may be read as is: as README .dgux.
DESCRIPTION
Perl 5.7/8.x for DG/UX ix86 R4.20MU0x
BUILDING PERL ON DG/UX
Non-threaded
Perl on DG/UX
Just run ./Configure script from the top directory. Then
give "make" to compile.
Threaded
Perl on DG/UX
If you are using as compiler GCC−2
.95.x rev( DG/UX ) an easy solution for
configuring perl in your DG/UX machine is to
run the command:
./Configure −Dusethreads −Duseithreads −Dusedevel −des
This will automatically accept all the defaults and in particular /usr/local/ as installation directory. Note that GCC−2 .95.x rev( DG/UX ) knows the switch −pthread which allows it to link correctly DG/UX ’s −lthread library.
If you want to change the installation directory or have a standard DG/UX with C compiler GCC−2 .7.2.x then you have no choice than to do an interactive build by issuing the command:
./Configure −Dusethreads −Duseithreads
In particular with GCC−2 .7.2.x accept all the defaults and *watch* out for the message:
Any additional ld flags (NOT including libraries)? [ −pthread]
Instead of −pthread put here −lthread. CGCC−2 .7.2.x that comes with the DG/UX OS does NOT know the −pthread switch. So your build will fail if you choose the defaults. After configuration is done correctly give "make" to compile.
Testing Perl
on DG/UX
Issuing a "make test" will run all the tests. If
the test lib/ftmp−security gives you as a result
something like
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
don’t panic and just set the sticky bit in your /tmp directory by doing the following as root:
cd / chmod +t /tmp (=set the sticky bit to /tmp).
Then rerun the tests. This time all must be OK .
Installing
the built perl on DG/UX
Run the command "make install"
