Well, I got an error “install_driver(Pg) failed: Can’t locate version.pm” while starting OpenCA 1.5.1 daemon on CentOS. This tutorial will explain how to fix OpenCA start error Can’t locate version.pm. Before I talk about the solution, have a look at the complete error message.
Starting OpenCA daemon:
# ./etc/init.d/openca start
Though the above command didn’t throw any message, I could find a detailed error in var/openca/log/stderr.log. Below is the snapshot of it.
install_driver(Pg) failed: Can't locate version.pm in @INC (@INC contains: /home/openca/lib/openca/perl_modules/perl5/x86_64-linux-thread-multi /home/openca/lib/openca/perl_modules/perl5 /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at /home/openca/lib/openca/perl_modules/perl5/x86_64-linux-thread-multi/DBD/Pg.pm line 19. BEGIN failed--compilation aborted at /home/openca/lib/openca/perl_modules/perl5/x86_64-linux-thread-multi/DBD/Pg.pm line 19. Compilation failed in require at (eval 288) line 3. Perhaps a module that DBD::Pg requires hasn't been fully installed at /home/openca/lib/openca/perl_modules/perl5/OpenCA/DBI.pm line 914. Compilation failed in require at /home/openca/etc/openca/openca_start line 66.
The error message indicates that it couldn’t locate version.pm file and perhaps a module that DBD::Pg has not been installed fully. Let’s install DBD::Pg.
Install DBD::Pg using cpan
cpan[1]> install DBD::Pg
However, cpan failed installing DBD::Pg and exited with the below error message.
Could not load DBI::DBD - is the DBI module installed? No 'Makefile' created'YAML' not installed, will not store persistent state TURNSTEP/DBD-Pg-3.7.4.tar.gz /usr/bin/perl Makefile.PL -- NOT OK Running make test Make had some problems, won't test Running make install Make had some problems, won't install Could not read metadata file. Falling back to other methods to determine prerequisites Failed during this command: TURNSTEP/DBD-Pg-3.7.4.tar.gz : writemakefile NO -- No 'Makefile' created
So I had install DBI::DBD module before installing DBD::Pg. Let’s go ahead and install DBI::DBD
Install DBI::DBD
cpan> install DBI::DBD Appending installation info to /usr/lib64/perl5/perllocal.pod TIMB/DBI-1.640.tar.gz /usr/bin/make install -- OK
Yes, I have now installed DBI::DBD module, let’s retry DBD::Pg installation via cpan.
cpan> install DBD::Pg
Ah! another error:
cp lib/Bundle/DBD/Pg.pm blib/lib/Bundle/DBD/Pg.pm cp Pg.pm blib/lib/DBD/Pg.pm /usr/bin/perl -p -e "s/~DRIVER~/Pg/g; s/^do\(/dontdo\(/" /usr/local/lib64/perl5/auto/DBI/Driver.xst > Pg.xsi /usr/bin/perl /usr/share/perl5/vendor_perl/ExtUtils/xsubpp -typemap /usr/share/perl5/ExtUtils/typemap Pg.xs > Pg.xsc && mv Pg.xsc Pg.c gcc -c -I/usr/include -I/usr/local/lib64/perl5/auto/DBI -D_REENTRANT -D_GNU_SOURCE -fno-strict-aliasing -pipe -fstack-protector -I/usr/local/include -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -DPGLIBVERSION=90223 -DPGDEFPORT=5432 -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -m64 -mtune=generic -DPERL_EXTMALLOC_DEF -Dmalloc=Perl_malloc -Dfree=Perl_mfree -Drealloc=Perl_realloc -Dcalloc=Perl_calloc -DVERSION=\"undef\" -DXS_VERSION=\"undef\" -fPIC "-I/usr/lib64/perl5/CORE" Pg.c In file included from Pg.xs:14:0: Pg.h:36:22: fatal error: libpq-fe.h: No such file or directory #include "libpq-fe.h" ^ compilation terminated. make: *** [Pg.o] Error 1 TURNSTEP/DBD-Pg-3.7.4.tar.gz /usr/bin/make -- NOT OK Running make test Can't test without successful make Running make install Make had returned bad status, install seems impossible Failed during this command: TURNSTEP/DBD-Pg-3.7.4.tar.gz : make NO
Now the error is “fatal error: libpq-fe.h: No such file or directory“. It means, I had to install a package or library that ships libpq-fe.h file. After googling, I understand ‘libpg-dev‘ is the library, but that’s for Ubuntu and Debian machines. So the corresponding package for CentOS is ‘postgresql-devel‘.
Install postgresql-devel using YUM
# yum install postgresql-devel ::::::::::::::::: Installed: postgresql-devel.x86_64 0:9.2.23-3.el7_4 Complete!
Ok. Hopefully, cpan should now install DBD::Pg without any problem. Let’s check it out.
Installing DBD::Pg again using cpan
cpan[3]> install DBD::Pg Running install for module 'DBD::Pg' Running make for T/TU/TURNSTEP/DBD-Pg-3.7.4.tar.gz Has already been unwrapped into directory /root/.cpan/build/DBD-Pg-3.7.4-JtTHAe Could not make: Unknown error Running make test Can't test without successful make Running make install Make had returned bad status, install seems impossible
What! cpan says install seems impossible? Nope, let’s install it manually. To do that, I had to go to .cpan directory located under user’s home and locate DBD-PG downloaded by cpan.
# cd /root/.cpan/build/DBD-Pg-3.7.4-ScxNAT
Let’s create Makefile now.
# perl Makefile.PL Configuring DBD::Pg 3.7.4 PostgreSQL version: 90223 (default port: 5432) POSTGRES_HOME: (not set) POSTGRES_INCLUDE: /usr/include POSTGRES_LIB: /usr/lib64 OS: linux Checking if your kit is complete... Looks good Using DBI 1.64 (for perl 5.016003 on x86_64-linux-thread-multi) installed in /usr/local/lib64/perl5/auto/DBI/ Writing Makefile for DBD::Pg
Cool. What about make?
#make chmod 755 blib/arch/auto/DBD/Pg/Pg.so cp Pg.bs blib/arch/auto/DBD/Pg/Pg.bs chmod 644 blib/arch/auto/DBD/Pg/Pg.bs Manifying blib/man3/Bundle::DBD::Pg.3pm Manifying blib/man3/DBD::Pg.3pm
Cool again, what about install?
# make install Files found in blib/arch: installing files in blib/lib into architecture dependent library tree Installing /usr/local/lib64/perl5/auto/DBD/Pg/Pg.so Installing /usr/local/lib64/perl5/auto/DBD/Pg/Pg.bs Installing /usr/local/lib64/perl5/DBD/Pg.pm Installing /usr/local/lib64/perl5/Bundle/DBD/Pg.pm Installing /usr/local/share/man/man3/Bundle::DBD::Pg.3pm Installing /usr/local/share/man/man3/DBD::Pg.3pm Appending installation info to /usr/lib64/perl5/perllocal.pod
Yes. I have now successfully installed “DBD::Pg” module. Now I started OpenCA daemon and it worked without any fuss.
Hope it helps someone out there.
