perldgux − Perl under DG/UX.


One can read this document in the following formats:

        man perldgux
        view perl perldgux
        explorer perldgux.html
        info perldgux

to list some (not all may be available simultaneously), or it may be read as is: as README .dgux.


Perl 5.7/8.x for DG/UX ix86 R4.20MU0x


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

    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"
