Compile problems

I am trying to get Embperl
(tried 1.2.0 1.2.1 and 1.3b2)
to compile with Perl 5.6
Apache 1.3.9 and mod_perl 1.22,
but when I do the make test I get to the ascii test and it dies.
Did I compile Perl wrong? I used the defaults. All other modules are
compiling fine. (DBI DBD::mysql MD5 mod_perl etc.)

Hi,
If it's any consolation, I got similar problems at this same
point with perl 5.6.0 on Win32, compiled with the the fork emulation
and threads disabled.

best regards,

I didn't have the time to test Perl 5.6. I guess some of the internals have
changed...

As soon as I get some free time, I will try it out. In the meantime, could
you make a stackbacktrace with gdb?

Do a

perldoc Faq.pod

and search for

"bactrace"

(It's a typo in the Faq.pod). This paragraph explain how to get a backtrace
and the next explains how to build a debug version of Embperl.

Gerald,

Ok. Is this what you are looking for?

Starting program: /usr/local/bin/perl test.pl

loading... ok

Testing offline mode...

ascii...
Program received signal SIGSEGV, Segmentation fault.
0x805e179 in Perl_gv_fetchfile ()

I will resend with debug enabled if it is.

That would be great. If you could do this, I think I would be able to fix
the bug, even without installing Perl 5.6 here

Gerald,

Here is the output from the debug version. I didn't see a LDDFLAGS but I saw
LDDLFLAGS, is that where I add the -g? (I added it there and nothing bad
happend :^)

Hope this helps.

Yes

Does it change anything, if you change line 75 in Embperl.xs from

if (gv && SvTYPE(gv) == SVt_PVGV)

to

if (gv && SvTYPE(gv) == SVt_PVGV && GvGP (gv))


?

It produced the same results. Failed on the read? of the ascii file.

This is the block for any one that doesn't want to dig into the source and to
show which lines are which after the modification suggested: (lines according
to pico anyway)

ok, it isn't so easy as I hoped...

I am going to install Perl 5.6 here and let you know when have any news.

No, it fails in cleanup, when it tries to determinate the filename of a the
sourcefile of a variable

Hi,

I just commit a few changes to the CVS that makes Embperl work with Perl
5.6. Either fetch it via annonymous CVS or wait until a new tarball is
generated at http://perl.apache.org/from-cvs/embperl.

The patch I send today morning (my time) was nearly correct. The correct
version is

change line 75 in Embperl.xs from

if (gv && SvTYPE(gv) == SVt_PVGV)

to

if (gv && SvTYPE(gv) == SVt_PVGV && GvGP (gv) && GvGP (gv) -> gp_file )


After this change Embperl work with Perl 5.6. make test still fails due to
changed error message in Perl 5.6. Theses are also corrected in the CVS
version.

Enjoy

Gerald
