| Subject: | SDK paths for RHEL5, ignore OpenLDAP libraries, build under perl 5.14.2 [patch] |
I use an automated process to install hundreds of module tarballs and it's
necessary for each tarball to PASS its tests.
Maybe should have supplied separate patches.
First problem is that you're supposed to provide a path to the SDK
installation for Makefile.PL to find the include and library paths.
However the RHEL5 RPM doesn't put these in one place (/usr/lib64
& /usr/include/mozldap. Makefile.PL was changed to explicitly set
these against $include_ldap and $lib_ldap variables.
One step forward, but make then failed with errors like:
API.c: In function ‘avref2charptrptr’:
API.c:205: error: ‘na’ undeclared (first use in this function)
Eventually found
http://osdir.com/ml/mozilla.devel.directory/2003-11/msg00004.html
so that make worked after defining '-DPERL_POLLUTE'.
[DMT 23-Apr-2011] downloaded 1.4.1 (2000-09-19) version from the Mercurial
repo mentioned on https://wiki.mozilla.org/LDAP_C_SDK.
This includes fixes for some things done in perldap-1.4.tar.gz.diff.
More importantly, I've modified Makefile.PL to explicitly use the
libraries installed by the mozldap rpm
# repoquery --list mozldap
/usr/lib64/libldap60.so
/usr/lib64/libldif60.so
/usr/lib64/libprldap60.so
/usr/lib64/libssldap60.so
/usr/share/doc/mozldap-6.0.5
/usr/share/doc/mozldap-6.0.5/README.rpm
Without doing this on a system with OpenLDAP libraries, the API.so library
fails
Error loading Mozilla::LDAP::API: perldap_init failed
I didn't run into this problem initially because distro-5.10.1-20100503 was
built on ldaptest. Later builds were on kolanut which does have the OpenLDAP
libraries, though Mozilla::LDAP failed:
symbol lookup error: .../lib/site_perl/5.10.1/x86_64-linux/auto/Mozilla/LDAP/API/API.so:
undefined symbol: ldap_set_option
because the perl was built in a different location (even if built in the final
location which was a symlink).
NB the Mozilla::LDAP tests are dummy ones, probably because real tests
would need access to an ldap server.
perl 5.14 no longer supports "#define PERL_POLLUTE"
but offers the alternative
perl Makefile.PL POLLUTE=1
Instead the patch restores the needed symbols.
Another approach might have been
http://search.cpan.org/~mhx/Devel-PPPort-3.20/PPPort_pm.PL
FYI The PL_ "namespace" for C symbols was introduced in perl 5.005
http://search.cpan.org/~flora/perl-5.14.2/pod/perl5005delta.pod#C_Source_Compatibility
"All Perl global variables that are visible for use by extensions now
have a PL_ prefix. New extensions should not refer to perl globals by
their unqualified names."
NB perl_destruct_level was needed for DBD::Ingres but not perldap-1.41
