Dmitry, am I right that this:

was output from your locally running the strace command?
I believe Ingo thought that was a snippet of Perl he was supposed to run, but I
think it’s instead strace’s output in (close to) C.

Hi Dimitry,
perl Makefile.PL DL_LOAD_FLAGS=1
was the solution! No reinstall or anything needed.
Thank you so much!
Great! I'm really curious what was than system... could you possibly send me
(ok if personally, too)
output of `uname -a` and `cc -v` ?
PS: I got syntax errors with this (even when using the right location of
Prima.so). Is this to be run in bash or perl?
openat(AT_FDCWD,
"/usr/local/lib/x86_64-linux-gnu/perl/5.34.0/auto/Prima/Prima.so",
O_RDONLY|O_CLOEXEC) = 5
I'm not sure I follow the question. Do I understand correctly that if you run
this from bash
$ perl -Iblib/arch -Iblib/lib -MPDL::Drawing::Prima -e 1
you get syntax errors?
/dk

Hi all
Sorry no clue either. But I'd do this:
1) remove all prima and P:D:P stuff, make sure no lingering .so files, then
clean reinstall.
2) nm won't help you here because the linking is done by dlopen() during
runtime, so
try this instead:
$ strace perl -Iblib/arch -Iblib/lib -MPDL::Drawing::Prima -e 1 2>&1 | grep
Prima.so
openat(AT_FDCWD,
"/usr/local/lib/x86_64-linux-gnu/perl/5.34.0/auto/Prima/Prima.so",
O_RDONLY|O_CLOEXEC) = 5
if it cannot find Prima.so then there's something wrong with the installation.
If however it can but cannot bind dynamically it might be that the system is so
old that
Prima couldn't detect that it needs an explicit RTLD_GLOBAL flag. Check this
then:
$ grep dl_load_flags Prima/Config.pm
dl_load_flags => 1,
so if it is not 1, you can try to recompile Prima with this:
perl Makefile.PL DL_LOAD_FLAGS=1
(but this is a really ancient stuff, I think I only used it on Sun/IRIX back
then..)

Hi Ingo,
I don’t know either. Dmitry, any ideas? I re-attach the nm output files.

Subject: Re: [Pdl-devel] PDL::Drawing::Prima
Hi Ed,
after further investigation, I think the Makefile is OK. I have essentially to
environments where I need this to run.
1) modern regularly updated linux boxes
2) servers with older stable releases (many kind of different software running,
not easily updated)
Both have perlbreew installations using perl-5.36.0 (with different aliases.
On the modern boxes, P:D:P works fine, while on the server it complains about unresolved
symbols (gimme_the_mate) during make test or apc_get_core_version when perl -Mblib -e
"use PDL::Drawing::Prima;", Both have Prima 1.73 installed.
The build log is inconspicuous, I can load the Utils module.
Checking if you have Prima 1.57 ... Yes (1.73)
Checking if you have ExtUtils::MakeMaker 0 ... Yes (7.64)
Checking if you have Test::More 0.88 ... Yes (1.302190)
Checking if you have PDL 2.037 ... Yes (2.089)
Building and testing PDL-Drawing-Prima-0.18
I am at a complete loss here. I attached the output of nm

Hi Ingo,
I think the relevant part of the attached Makefile.PL is (as changed by you):
if ($Prima::Config::Config{dlname}){
my ($primalib,
$primapath)=fileparse($Prima::Config::Config{dlname});
$hash{LIBS}->[0] = " -L$primapath -lPrima "
}
You’ve changed it from an append (.=) to an assign, which might explain why it
doesn’t work. Is there a reason you did that? Also, why did you remove the
existing code below?
$hash{LIBS}[0] .= " $Prima::Config::Config{libs}"
if $Prima::Config::Config{libs};
What errors did you get? Are you on Ubuntu? Because I’m using Ubuntu, and
building P:D:Prima here doesn’t need to link Prima - the dynamic linker takes
care of it at runtime.
Best regards,
Ed

Hi,
this module does not find Prima.so (from Prima).
Makefile.PL needs to lock at Prima::Config::Config{dlname} and set the correct
LIBS field. I failed to make it work.
I got the parts necessary extracted, but make seems to ignore it. This results
in unresolved symbols from Prima.
