Test failure: unable to find Add

[bbrtj]

The module does not test correctly for me. I did some digging but wasn't able to make it work.
I'm on FreeBSD 13.0-RELEASE with fpc 3.20. I digged into FFI to see the nm command that it uses:

# nm -g -P -D libtest.so
Add T 0000000000010130 0000000000000005
operatingsystem_parameter_argc U
operatingsystem_parameter_argv U
operatingsystem_parameter_envp U

So there seems to be the correct symbol in the package, but I still get this error (with Carp::Always):

On cpantesters, FreeBSD has no case of passing the tests, so I think this may be FreeBSD specific. Unfortunately, cpantesters has a bug that pervents me from seeing test reports, so I can only guess. I can paste more outputs if you need, just give me the commands to run.

Edit: On the other hand, FFI::Platypus::Lang::C installed without any problems for me, if that helps
Edit2: On the other hand, no wonder it doesn't test well on FreeBSD, since the installation requires manual action, as described in #18

I'm trying to dig into this locally. The shared object library does not seem to load correctly in FFI::Platypus::DL::dlopen with error:

warning: error loading t/ffi/libtest.so: t/ffi/libtest.so: Undefined symbol "operatingsystem_parameter_envp"

This is most likely a FPC bug: zamronypj/mod_pascal#1

@bbrtj I am going to close assuming this is an issue with FPC. If it turns out to be something that we can do I am happy to re-open.
