Обсуждение: [GENERAL] PG 10 and perl
I'm not subscribed to the -devel list, so hopefully I can post this here. I'm running slackware 14.2 I have the system perl (5.24) installed, and also perlbrew with perl 5.26 installed. In PG 9.5 this worked fine, and compiling and running PG used the 5.26 version of perl: root@firefly:/usr/local/pg95/lib/postgresql# ldd plperl.solibperl.so => /opt/perl5/perls/perl-5.26/lib/5.26.1/x86_64-linux-thread-multi/CORE/libperl.so(0x00007f81e8bde000) I started playing with 10, and cannot get it to use the right version of perl. I'll only use the system version: root@firefly:/usr/local/pg10/lib/postgresql# ldd plperl.solibperl.so => /usr/lib64/perl5/CORE/libperl.so (0x00007fc9c67d4000) But, here's the thing. The config.log reports 5.26 version: configure:7752: checking for perl configure:7770: found /opt/perl5/perls/perl-5.26/bin/perl configure:7782: result: /opt/perl5/perls/perl-5.26/bin/perl configure:7804: using perl 5.26.1 configure:7837: checking for Perl archlibexp configure:7841: result: /opt/perl5/perls/perl-5.26/lib/5.26.1/x86_64-linux-thread-multi configure:7843: checking for Perl privlibexp configure:7847: result: /opt/perl5/perls/perl-5.26/lib/5.26.1 configure:7849: checking for Perl useshrplib configure:7853: result: true configure:7862: checking for CFLAGS recommended by Perl configure:7865: result: -D_REENTRANT -D_GNU_SOURCE -fwrapv -fno-strict-aliasing -pipe -fstack-protector -strong -I/usr/local/include -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -D_FORTIFY_SOURCE=2 configure:7867: checking for CFLAGS to compile embedded Perl configure:7870: result: configure:7874: checking for flags to link embedded Perl configure:7891: result: -fstack-protector-strong -L/usr/local/lib -L/opt/perl5/perls/perl-5.26/lib/5 .26.1/x86_64-linux-thread-multi/CORE -lperl -lpthread -lnsl -ldl -lm -lcrypt -lutil -lc <snip> configure:15976: checking for perl.h configure:15976: gcc -c -Wall -Wmissing-prototypes -Wpointer-arith -Wdeclaration-after-statement -Wendi f-labels -Wmissing-format-attribute -Wformat-security -fno-strict-aliasing -fwrapv -fexcess-precision=s tandard -O2 -fPIC -DLINUX_OOM_SCORE_ADJ=0 -D_GNU_SOURCE -I/opt/perl5/perls/perl-5.26/lib/5.26.1/x86_6 4-linux-thread-multi/CORE conftest.c >&5 configure:15976: $? = 0 configure:15976: result: yes configure:15991: checking for libperl configure:16007: gcc -o conftest -Wall -Wmissing-prototypes -Wpointer-arith -Wdeclaration-after-stateme nt -Wendif-labels -Wmissing-format-attribute -Wformat-security -fno-strict-aliasing -fwrapv -fexcess-pr ecision=standard -O2 -fPIC -DLINUX_OOM_SCORE_ADJ=0 -D_GNU_SOURCE -I/opt/perl5/perls/perl-5.26/lib/5.2 6.1/x86_64-linux-thread-multi/CORE conftest.c -fstack-protector-strong -L/usr/local/lib -L/opt/per l5/perls/perl-5.26/lib/5.26.1/x86_64-linux-thread-multi/CORE -lperl -lpthread -lnsl -ldl -lm -lcrypt -l util -lc >&5 configure:16007: $? = 0 configure:16008: result: yes <snip> ac_cv_path_PERL=/opt/perl5/perls/perl-5.26/bin/perl <snip> perl_archlibexp='/opt/perl5/perls/perl-5.26/lib/5.26.1/x86_64-linux-thread-multi' perl_embed_ccflags='' perl_embed_ldflags=' -fstack-protector-strong -L/usr/local/lib -L/opt/perl5/perls/perl-5.26/lib/5.26. 1/x86_64-linux-thread-multi/CORE -lperl -lpthread -lnsl -ldl -lm -lcrypt -lutil -lc' perl_privlibexp='/opt/perl5/perls/perl-5.26/lib/5.26.1' perl_useshrplib='true' Thanks for your time, -Andy -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general

I'm about to go down this path to prepare for 10.0, but I haven't had time yet. You don't show your configure command, but did you set PERL there as well as have it in your PATH? Here's what I've donein the past: ./configure --prefix=/opt/pg-9.5 --with-system-tzdata --with-perl PERL=/opt/perl/bin/perl and it used our custom Perl just fine. If you did that, I'm not sure what else to say at the moment. I hope to get aroundto checking out RC1 early next week though and I'll be using 5.26 as well. Hmm, given your report, I'll try to move it up my ToDo list to give myself more time. I'll report back here if I get it towork and haven't seen a reply by you about you getting it to work also.

Hm, I don't think we've changed anything about that in v10.

That's good, but what's probably missing is an "rpath" specification when
linking plperl.so. Did you build with --disable-rpath, perhaps? That's
the usual recommendation when building for Linux, but if you want to use
any non-default libraries, you can't do it.
Go into src/pl/plperl, remove and remake plperl.so, and see whether the
link command includes anything like
-Wl,-rpath,'/usr/lib64/perl5/CORE',--enable-new-dtags
(That's what I see when building with a stock Linux Perl configuration and
rpath enabled.) If there's no such switch, or if it doesn't point to
where the libperl.so that you want to use is, then there's your problem.

The SlackBuild script I'm using installs to /usr/local/pg95 still. So I was compiling and installing 10rc1 into pg95.
