Re: Embedding Perl Interpreter/DynaLoader

Thank you all again for the help, Per the suggestion, I removed the '-L' from the DynaLoader.a chunk, and things compiled fine. Whew!

The compile string is now:

cc '-Wl,-E' -I "/usr/local/include" -I "/opt/perl/lib/5.6.1/PA-RISC1.1
+-thread-multi/CORE" -o codeGen xsinit.c codeGen.
c -L/usr/local/lib -L "/opt/perl/lib/5.6.1/PA-RISC1.1-thread-multi/COR
+E" "/opt/perl/lib/5.6.1/PA-RISC1.1-thread-multi/auto/DynaLoa
der/DynaLoader.a" -lperl -lnsl -lm -lc -lcrypt -lsec  -L/usr/local/lib
[download]

Unfortunately, when I run the executable I still get that same ol' frustrating error:

Can't load module File::Glob, dynamic loading not available in this pe
+rl.
  (You may need to build a new perl executable which either supports
  dynamic loading or has the File::Glob module statically linked into 
+it.)
Compilation failed in require at search.pl line 8.
BEGIN failed--compilation aborted at search.pl line 8.
Undefined subroutine &main::search_files called at search.pl line 8.
[download]

And, of course, things are lovely if I remove any reference to glob(). Beyond this point, I'm not sure how to create an executable that "supports dynamic loading". Hmmm, perhaps naively I thought DynaLoader.a would do that. Perhaps - if there are no more obvious things for me to try - I will make do w/o glob() as part of my embedded Perl.

Thank you all,

MatthewFrancis

OK - now the problem is that the libperl.so/.a is from a build that does not include the dl_open.xs (or whichever implementation is used under HP-UX) module. Is the C compiler you are using the basic C compiler that comes with HP-UX? I have a feeling that if that's the case then that C compiler is an old K&R compiler that can't be used to build dynamically loadable modules, etc. Maybe it'd be worth it to download/install gcc? I think there is a site that offers binaries, similar to sunfreeware for Solaris. Michael	[reply]

Interesting. I've heard of these ".so" files before, but we don't have any on our server. All we've got is the libperl.a. Does this mean that our current Perl installation is broken/incomplete? If so, I am going to see what I can do about having our Perl reinstalled. For what it's worth, we're using (courtesy of of "perl -v"): `Binary build 633 provided by ActiveState Corp. http://www.ActiveState. +com Built 21:04:57 Jun 17 2002` [download] If it's a binary build, then, perhaps the .so file was never there to begin with. Would you recommend actually building it ourselves, as opposed to working with a precompiled binary? Yes, I believe the compiler is the standard, no-frills HP-UX compiler. And - please forgive the remedial nature of my questions - how can I statically link the File::Glob module into my perl executable? What do I have to provide at the command line in order to make this happen? Thank you again, for the help MatthewFrancis	[reply] [d/l]

Actually you probably have .sl files instead (that's the shared library extension on HP-UX, IIRC). I don't think that the ActiveState binary is incomplete - but I'm almost certain that you'll need gcc or some other modern compiler to build any binary for use with perl. I would start by installing gcc, and see if that solves your problems. Michael	[reply]
