It turned out to be that the latest ExtUtils​::ParseXS was installed, and
xsubpp is filling in a croak_xs that looks like​:

  STATIC void
  S_croak_xs_usage(const CV *const cv, const char *const params)
  {
  const GV *const gv = CvGV(cv);

  PERL_ARGS_ASSERT_CROAK_XS_USAGE;

  if (gv) {

If we add dTHX; to the beginning of the function, compilation succeeds.
Does ExtUtils​::ParseXS need something like​:

#ifdef PERL_NO_GET_CONTEXT
  dTHX;
#endif

which it has on other functions?

It turned out to be that the latest ExtUtils​::ParseXS was installed,
and
xsubpp is filling in a croak_xs that looks like​:

STATIC void

If we add dTHX; to the beginning of the function, compilation
succeeds.
Does ExtUtils​::ParseXS need something like​:

#ifdef PERL_NO_GET_CONTEXT
dTHX;
#endif

which it has on other functions?

I'm confused as to where in the source code you think such a change should be applied. I don't see that 'ifdef' anywhere in ExtUtils-ParseXS.

I don't recall my original reasoning.

However S_croak_xs_usage in core does this​:

  vutil.h​:S_croak_xs_usage(pTHX_ const CV *const cv, const char *const params);
  vutil.h​:S_croak_xs_usage(pTHX_ const CV *const cv, const char *const params)
  vutil.h​:#define croak_xs_usage(a,b) S_croak_xs_usage(aTHX_ a,b)
  vutil.h​:#define croak_xs_usage S_croak_xs_usage

Whereas ExtUtils​::ParseXS only does this​:

  lib/ExtUtils/ParseXS/Utilities.pm​:S_croak_xs_usage(const CV *const
cv, const char *const params);
  lib/ExtUtils/ParseXS/Utilities.pm​:S_croak_xs_usage(const CV *const
cv, const char *const params)
  lib/ExtUtils/ParseXS/Utilities.pm​:#define croak_xs_usage
S_croak_xs_usage

Seems to me like it's missing the pTHX depending on PERL_IMPLICIT_CONTEXT...

S_croak_xs_usage

@wolfsage, can you review this ticket for closability?

In your most recent comment, you referred to S_croak_xs_usage, noting that it was found in file vutil.h. However, this appears to no longer be the case.

$ ack -l S_croak_xs_usage .
dist/ExtUtils-ParseXS/Changes
dist/ExtUtils-ParseXS/lib/ExtUtils/ParseXS/Utilities.pm

Nor does this function still appear in the upstream version.pm:

$ ack S_croak_xs_usage .
$ 
# no output

Since (i) @xsawyerx is planning a new CPAN release of EU::PXS, and (ii) there are other EU::PXS issues pending, we should see if we can clean up older tickets for this distro.

Thank you very much.

Maybe it's better to do the release without it so as to not stress anyone to wrap something up for the release. Once one is done, it's easier to do the next one.

I think the steps (for anyone) to confirm if this is still an issue are:

• For a threaded and non-threaded build:
  • Build perl 5.8.5
  • Install ExtUtils::ParseXS
  • Attempt to install an XS module like Devel::PPPort

If it still fails similarly, some work could be done (if we want to support 5.8.5 still, assuming this issue also doesn't affect other perl versions)

That's cool. Your volunteering to do a CPAN release just got me to look at old tickets, and this appeared to be the most closable.
