Marpa::R2 8.000000 is out

[Jeffrey Kegler]

I have uploaded a new indexed release of Marpa::R2: 8.000000: https://metacpan.org/pod/distribution/Marpa-R2/pod/Marpa_R2.pod

It fixes a bug, which under unusual circumstances caused the integer arguments of $recce->resume() or $recce->lexeme_complete() to be ignored.

Hi Jeff,

Getting error while installing the Marpa::R2 module.

# perl Build test

Using built-in Libmarpa

t/00-load.t ............ Bailout called.  Further testing stopped:  Could not load Marpa::R2

# Can't load '/tmp/ITM_Audit_Scripts/Marpa-R2-8.000000/blib/arch/auto/Marpa/R2/R2.so' for module Marpa::R2: rtld: 0712-001 Symbol __builtin_expect was referenced

#       from module /tmp/ITM_Audit_Scripts/Marpa-R2-8.000000/blib/arch/auto/Marpa/R2/R2.so(), but a runtime definition

#           of the symbol was not found. at /usr/opt/perl5/lib/5.20.1/aix-thread-multi/DynaLoader.pm line 193.

#  at t/00-load.t line 24

# Compilation failed in require at t/00-load.t line 24.

FAILED--Further testing stopped: Could not load Marpa::R2

Kindly need your help

Thanks and Regards

Krishna

This error typically means a bad Perl installation, or that Marpa::R2 was built with a Perl different from the one that is attempting to load it.

Best, jeffrey

/usr/opt/perl5_5203/bin/perl -V         --- GCC - gcc -maix64 -maix64

/usr/bin/perl -V                        --- XLC - cc='xlc_r -q32'

I tried with the recent updated module from Meta::Cpan

My first guess would be that the crucial messages are the ones in this series:

# Can't load '/tmp/ITM_Audit_Scripts/Marpa-R2-8.000000/blib/arch/auto/Marpa/R2/R2.so' for module Marpa::R2: rtld: 0712-001 Symbol _marpa_v_trace was referenced
#       from module /tmp/ITM_Audit_Scripts/Marpa-R2-8.000000/blib/arch/auto/Marpa/R2/R2.so(), but a runtime definition
#           of the symbol was not found.

Things I would look at first are paths, and the R2.so file itself -- does it actually exist, does it look like it was built right, does it contain an _marpa_v_trace symbol, what happens when you trace the link loader, etc.?

As a random guess, perhaps AIX has special rules about symbol visibility, which explain why it is not finding the symbols in R2.so.

Anyone else with suggestions?

Hope this helps, jeffrey

Hi Jeff,

File exists, how to verify the link loader ?

# ls -ltr /tmp/ITM_Audit_Scripts/Marpa-R2-8.000000/blib/arch/auto/Marpa/R2/R2.so

On my system, commands to examine the file are nm, objdump and ldd.  They have man pages and the ld.so man page describes environment variables which can be set to do tracing.  The environment variable can be tricky to use -- a bad choice can make your current terminal session unusable.

First think I'd be curious to know is are all those "not found" symbols actually defined in R2.so, and if so, how?
