BUILDING PERL ON DG/UX
Non-threaded Perl on DG/UX
Just run ./Configure script from the top directory. Then give "make"
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
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"
