Perl 5.8.0 是否包含符号 Perl_sv_2pv?
Hi friends,
Perl 5.8.0 seems a bit strange. I encounterred a trouble in my dynamic library which uses this symbol of Perl:
ld.so.1: perl: fatal: relocation error: file /opt/mylib/libAPIPerl.so: symbol Perl_sv_2pv: referenced symbol not found
Killed
Solaris 9/10
Perl was built from source code tar ball.
zcyds4d6-85> perl -v
This is perl, v5.8.0 built for sun4-solaris-64int
zcyds4d6-89> nm /bin/perl | grep -i Perl_sv_2pv
[2590] | 597800| 2980|FUNC |GLOB |0 |11 |Perl_sv_2pv_flags
[2234] | 597504| 28|FUNC |GLOB |0 |11 |Perl_sv_2pv_nolen
[2106] | 601164| 76|FUNC |GLOB |0 |11 |Perl_sv_2pvbyte
[921] | 601140| 24|FUNC |GLOB |0 |11 |Perl_sv_2pvbyte_nolen
[1338] | 601264| 76|FUNC |GLOB |0 |11 |Perl_sv_2pvutf8
[1487] | 601240| 24|FUNC |GLOB |0 |11 |Perl_sv_2pvutf8_nolen
But from perl5.6.1 to perl 5.8.8, I can find the reference in every release except 5.8.0.
Perl5.8.4 sample:
nm /usr/local/bin/perl | grep -i Perl_sv_2pv
[1926] | 596152| 28|FUNC |GLOB |0 |9 |Perl_sv_2pv
[1540] | 596180| 2872|FUNC |GLOB |0 |9 |Perl_sv_2pv_flags
[1677] | 595996| 28|FUNC |GLOB |0 |9 |Perl_sv_2pv_nolen
[2571] | 599204| 132|FUNC |GLOB |0 |9 |Perl_sv_2pvbyte
[2454] | 599180| 24|FUNC |GLOB |0 |9 |Perl_sv_2pvbyte_nolen
[2084] | 599360| 132|FUNC |GLOB |0 |9 |Perl_sv_2pvutf8
[2450] | 599336| 24|FUNC |GLOB |0 |9 |Perl_sv_2pvutf8_nolen
The Perl 5.8.0 delta ( http://search.cpan.org/dist/perl/pod/perl58delta.pod#Perl_get_sv ) said that it that is no more the case. what does it mean?
Perl_get_sv
You may get errors like 'Undefined symbol "Perl_get_sv"' or "can't resolve symbol 'Perl_get_sv'", or the symbol may be "Perl_sv_2pv". This probably means that you are trying to use an older shared Perl library (or extensions linked with such) with Perl 5.8.0 executable. Perl used to have such a subroutine, but that is no more the case. Check your shared library path, and any shared Perl libraries in those directories.
Sometimes this problem may also indicate a partial Perl 5.8.0 installation, see "Mac OS X dyld undefined symbols"
I also found a link about this issue, but it did not say whether this symbol was kept in Perl 5.8.0.

Why is Perl 5.8.0 so strange? How to resolve this problem?
Thanks in advance.
