When running the self tests for the 0.12 distfile from cpan for the pkgsrc package with perl-5.26.1, I see:

Thanks for the report! Could you tell me what platform you're on?

0-wiz-0 commented 7 years ago

Sure, that's on NetBSD-8.99.5/amd64.

mohawk2 commented 5 years ago

Could you try this with the new 0.13? Its tests give a lot more info. Closing till then, but please do give the test outputs if it doesn't work!

0-wiz-0 commented 5 years ago

Sure, here's the output with 0.13:

mohawk2 commented 5 years ago

So it's failing only on EUMM. Could you look in t/makemaker/Makefile, and show the contents of the # MakeMaker Parameters section near the top?

mohawk2 commented 5 years ago

Also, what version of EUMM have you installed? Also, could you show output of perl -V?

0-wiz-0 commented 5 years ago

Here are the parameters:

#   MakeMaker Parameters:

#     BUILD_REQUIRES => {  }
#     CCFLAGS => q[ -O2 -g -D_FORTIFY_SOURCE=2 -fstack-check -pthread -I/usr/include -fwrapv -fno-strict-aliasing -pipe -xc++]

#     TEST_REQUIRES => {  }
#     VERSION_FROM => q[lib/CppGuessTest.pm]
#     dynamic_lib => { OTHERLDFLAGS=>q[ -lstdc++ -lgcc_s] }

I don't know what EUMM is, I have the following dependencies installed:

inc-latest 0.500
Module-Build 0.42240
Capture-Tiny 0.48

perl -V says:

EUMM = ExtUtils::MakeMaker. You can see which version you have with the V module (cpanm V if you don't):

perl -MV=ExtUtils::MakeMaker

mohawk2 commented 5 years ago

Also, I asked two questions and I still need an answer to:

Could you look in t/makemaker/Makefile, and show the contents of the # MakeMaker Parameters section near the top?

Reason is your MB build works, so EUCppG is getting the right info, but EUMM for some reason isn't adding the linker flags to the actual link command, and I expect that's why it's not working. Let's find out!

The parameters are in my previous reply, right after "Here are the parameters:".

I tried:

# perl -MExtUtils::MakeMaker -le 'print $ExtUtils::MakeMaker::VERSION'  
7.34

I hope that's what you wanted to see?

mohawk2 commented 5 years ago

The parameters are in my previous reply, right after "Here are the parameters:".

So you did! Poor comprehension on my part.

And 7.34 was what I'd expect for 5.28.1. Could you please look in t/makemaker/Makefile for the dynamic_lib section? For comparison, here is mine:

# --- MakeMaker dynamic_lib section:
# This section creates the dynamically loadable objects from relevant
# objects and possibly $(MYEXTLIB).
ARMAYBE = :
OTHERLDFLAGS =  -lstdc++
INST_DYNAMIC_DEP = 
INST_DYNAMIC_FIX = 

$(INST_DYNAMIC) : $(OBJECT) $(MYEXTLIB) $(INST_ARCHAUTODIR)$(DFSEP).exists $(EXPORT_LIST) $(PERL_ARCHIVEDEP) $(PERL_ARCHIVE_AFTER) $(INST_DYNAMIC_DEP) 
        $(RM_F) $@
        $(LD)  $(LDDLFLAGS)  $(LDFROM) $(OTHERLDFLAGS) -o $@ $(MYEXTLIB) \
          $(PERL_ARCHIVE) $(LDLOADLIBS) $(PERL_ARCHIVE_AFTER) $(EXPORT_LIST) \
          $(INST_DYNAMIC_FIX)
        $(CHMOD) $(PERM_RWX) $@

By the way, I note your kernel seems to be recently built. Are you using a NetBSD perl "port"? If so, could you see if there are any changes it makes to dynamic linking? The make output for the linking line looks like it has the flags I would expect replaced by what looks bespoke.

0-wiz-0 commented 5 years ago

The section you asked for looks like this:

# --- MakeMaker dynamic_lib section:
# This section creates the dynamically loadable objects from relevant
# objects and possibly $(MYEXTLIB).
ARMAYBE = :
OTHERLDFLAGS =  -lstdc++ -lgcc_s
INST_DYNAMIC_DEP = 
INST_DYNAMIC_FIX = 

$(INST_DYNAMIC) : $(OBJECT) $(MYEXTLIB) $(INST_ARCHAUTODIR)$(DFSEP).exists $(EXPORT_LIST) $(PERL_ARCHIVEDEP) $(PERL_ARCHIVE_AFTER) $(INST_DYNAMIC_DEP) 
        $(RM_F) $@
        $(LD)  $(LDDLFLAGS)  $(LDFROM) $(OTHERLDFLAGS) -o $@ $(MYEXTLIB) \
          $(PERL_ARCHIVE) $(LDLOADLIBS) "-L$(PERL_INC)" "-Wl,-R$(INSTALLARCHLIB)/CORE" "-Wl,-R$(PERL_ARCHLIB)/CORE" -lperl $(PERL_ARCHIVE_AFTER) $(EXPORT_LIST) \
          $(INST_DYNAMIC_FIX)
        $(CHMOD) $(PERM_RWX) $@

I am indeed using the perl package from pkgsrc. The patches that pkgsrc applies on top of the distribution file are visible here: https://github.com/NetBSD/pkgsrc/tree/trunk/lang/perl5/patches I hope you find what you're looking for there!

mohawk2 commented 5 years ago

It looks like your EUMM is inserting text between $(LDLOADLIBS) and $(PERL_ARCHIVE_AFTER).

Is there any way I could login to your machine to see what's going on? If not, could you at least edit t/makemaker/Makefile to have that recipe read (please make sure the leading whitespace is tab characters):

$(INST_DYNAMIC) : $(OBJECT) $(MYEXTLIB) $(INST_ARCHAUTODIR)$(DFSEP).exists $(EXPORT_LIST) $(PERL_ARCHIVEDEP) $(PERL_ARCHIVE_AFTER) $(INST_DYNAMIC_DEP) 
        $(RM_F) $@
        echo OTHERLDFLAGS is $(OTHERLDFLAGS)
        $(LD)  $(LDDLFLAGS)  $(LDFROM) $(OTHERLDFLAGS) -o $@ $(MYEXTLIB) \
          $(PERL_ARCHIVE) $(LDLOADLIBS) "-L$(PERL_INC)" "-Wl,-R$(INSTALLARCHLIB)/CORE" "-Wl,-R$(PERL_ARCHLIB)/CORE" -lperl $(PERL_ARCHIVE_AFTER) $(EXPORT_LIST) \
          $(INST_DYNAMIC_FIX)
        $(CHMOD) $(PERM_RWX) $@

then exercise it with:

cd t/makemaker # if not there already
rm blib/arch/auto/CppGuessTest/CppGuessTest.so
make

and tell me output?

0-wiz-0 commented 5 years ago

Ok, quite possibly this might be a symptom of the build infrastructure I use. The pkgsrc framework (in which I ran the tests) has a compiler wrapper that modifies the arguments. When I run the test outside the framework, it succeeds. I think I'll close this now, sorry for wasting your time :(

mohawk2 commented 5 years ago

Glad to, let's say, help! :-)
