suggestions, corrections and input welcome and requested.

Compiling Perl with DBI and DBD::Informix in Static Mode
First Things First
Download Perl - We're using 5.6 but the same works with 5.005
Create a directory structure to hold your downloads. Here's what we
use:
Base Directory: /src/perl
Perl goes in /src/perl/perl5.6
Uninstalled src in /src/perl/uninstalled
Installed src (after compiling) in /src/perl/installed
On some SCO systems, once DBD::Informix is compiled static, anything
compiled in afterwards chokes on missing libraries even though the exist.
When I have time, I'll find out why and fix it. But for a workaround,
compile everything you want except DBD::Informix and then create a safe
copy of the perl structure. Our perl is installed as /usr/local/lib/perl5
with binaries in /usr/local/perl so once everything but DBD::Informix is
compiled, we make a safe copy of the structure using the following:
#!/bin/sh
cd /usr/local/bin
rm -f perl*.safe > /dev/null 2>&1
for i in perl*
do
cp $i $i.safe
done
cd /usr/local/lib
rm -r perl5.safe > /dev/null 2>&1
mkdir perl5.safe
cd perl5
tar cf - . | (cd /usr/local/lib/perl5.safe ; tar xvf - )
If more modules need to be compiled into the static perl later:
mv /usr/local/lib/perl5 /usr/local/lib/perl5.old
mkdir /usr/local/lib/perl5
cd /usr/local/lib/perl5.safe
tar cf - . | (cd /usr/local/lib/perl5 ; tar xvf - )
This effectivly removes DBD::Informix from the structure so that more
modules can be compiled. After adding new modules, simply make a new
/usr/local/lib/perl5.safe directory using the above method and then compile
in DBD::Informix.
If you want to know if your system shows the same problem duriing compile,
build Perl Static, compile in DBI and then DBD::Informix, then try to
compile in one other module. If it fails, you'll need to use the above method.
The compile:
We've used both gcc and SCO's Ansi C and find that SCO's Ansc makes for a
smaller perl binary.
After reading the README file for your system, run Configure
sh ./Configure
Most answers you'll already know. Here are the important ones for static
(at least on SCO)
If this doesn't make any sense to you, just accept the default 'n'.
Build a threading Perl? [n]
If this doesn't make any sense to you, just accept the default 'n'.
Build Perl for multiplicity? [n]
Directories to use for library searches?
[/usr/local/lib /lib /usr/lib /usr/ccs/lib]
Perl can be built to use the SOCKS proxy protocol library. To do so,
Configure must be run with -Dusesocks.
If this doesn't make any sense to you, just accept the default 'n'.
Build Perl for SOCKS? [n]
What libraries to use?
[-lintl -lsocket -lnsl -lndbm -ldbm -lld -lm -lc -lcrypt -lsec -lPW -lx]
What optimizer/debugger flag should be used? [-O0]
Any additional cc flags?
[-U M_XENIX -D PERL_SCO -D PERL_SCO5 -w0 -belf -I/usr/local/include]
Any additional ld flags (NOT including libraries)? [ -L/usr/local/lib]
Shall I use /bin/nm to extract C symbols from the libraries? [n]
Do you wish to use dynamic loading? [n]
Use the experimental PerlIO abstraction layer? [n]What extensions do you
wish to include?
[B ByteLoader Data/Dumper Devel/DProf Devel/Peek Fcntl File/Glob IO
IPC/SysV NDB
M_File Opcode POSIX SDBM_File Socket Sys/Hostname Sys/Syslog attrs re]
Answer the rest of the questions to your liking, check config.sh to be sure
it's cool and then run
make
make test
make install
Work with perl as is for a bit to be sure it's really working. Then
compile in DBD and any other mods you might want.
Here's the list of what we use and the order they're compiled in:
DBI
CDB_File
Time
File
libnet
Digest-MD5-2.15
MD5-2.02
SQL
TimeDate
MIME-Base64-2.12
URI
HTML-Parser-3.25
HTML-Tagset-3.03
libwww-perl-5.5396
MailTools-1.40
IO-Tty-0.04
IO-Stty-.02
Expect-1.12
NNTPClient-0.37
News-Scan-0.51
FAQ-OMatic-2.711
Net-SNMP-3.6
POP3Client-2.9
Net-TFTP-0.12
------------------------------------perl5.safe created see above
-----------------------
DBD-Informix-1.00.PC1
For each module, use the same steps
When a Configure command exists
sh Configure
check config.sh
Then
make
make test
make install
For DBD::Informix
Make sure your esqlc is loaded and working. Make sure you can compile
and run regular esqlc programs and make sure your demo database is up and
working.
Trick for static:
cd $INFORMIXDIR/bin
mv esql esql.bin
create a new esql:
#!/bin/sh
$INFORMIXDIR/bin/esql.bin -static $*
chmod 755 esql
This makes esql compile static every time. Make sure that's what you want.
