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.so libperl.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.so libperl.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@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
