       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

       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 installa-
       tion 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 com-

       ./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 con-
       figuration 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

       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"
