Lets see, you can write code in unix with any of the myriad of text editors available - try to familiarise yourself with either the vi or the emacs editors. For compiling code, you can use the GCC (have to install it seperately - though it will usually be available on Linux by default). Many systems come with their native C compilers, like Sun Studio on Sun or HP's HP C compiler.
On almost all systems, the libraries are available under /usr/lib, while includes are under /usr/include. Both libraries and include files specific to a certain products may be installed elsewhere during product installation as well.
As for debugging, you can use GDB which is part of the GCC. For more info on GCC, go

PERLDGUX(1) Perl Programmers Reference Guide PERLDGUX(1)
NAME
perldgux - Perl under DG/UX.
SYNOPSIS
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.
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"
