Failure building PL/Ruby on MacOS X 10.3

Gavin Kistner

I have Ruby 1.8.1, PostgreSQL 7.4.1, mod_ruby 1.1.2, eRuby 1.0.5,
postgres 0.7.1, and Apache 2.0.48 installed and playing nicely together.

One final piece...I want PL/Ruby in my PGSQL. But it's not liking me:

I *do* see /src/include/utils/array.h ... did the src hierarchy for
PGSQL change and the make file needs to be updated to match?

Any thoughts on how I can get this built?

Further information:
I tried editing plruby.h to point to the array.h file I saw:


#if PG_PL_VERSION >= 74
- #include "server/utils/array.h"
+ #include "utils/array.h"
#endif

And hey! It compiled OK!
But then...awww...it fails just about every test with 'make test'.

Output follows.

I'm not familiar with the packaging system used in Mac OS X, but have
you installed the 'postgresql-devel' package (which contains the
necessary *.h files)? If yes, then check the correct path for
server/utils/array.h (e.g. is it really in
/usr/local/src/postgresql-7.4.1/src/include/?)

Indeed, the problem (as I realized when I inspected the error messages
and thought a bit) was that the pgsql commands weren't in my path.

When I put them there, I got new errors with 'make test', which I
believe had to do with the fact that it was invoking psql without a
database name, which was thus looking for a database named 'root' (the
user I was running as).

I decided that make test was full of bunk, and went on and installed the
compiled code. I'm happy to report, PL/Ruby is working nicely :)


So, in summary (for the record/archives):

In order to build PL/Ruby 0.3.8 to work with PostgreSQL 7.4.1 (the
standard .tar.gz source, not some special package for OS X) I had to
change one line in plruby.h from
#include "server/utils/array.h"
to
#include "utils/array.h"

After that, I needed (not unexpectedly) to explicitly specify the paths
to pgsql (built version and source includes):

ruby extconf.rb --with-pgsql-dir=/usr/local/pgsql
--with-pgsql-srcinc=/usr/local/src/postgresql-7.4.1/src/include


After the above, making and installing the code worked:
make
make install

And I just had to ignore the fact that make test didn't work at all.

FWIW, this was not a MacOS X specific package. It was precisely:

ftp://ftp9.us.postgresql.org/pub/mirrors/postgresql/source/v7.4.1/postgresql-base-7.4.1.tar.gz

which has array.h inside /src/include/utils/ and *not*
/src/include/server/utils/

Dunno when this changed, but seems to be a minor broken part of the
PL/Ruby install.

be careful - if you run ldd on the postgres.so lib you'll probably see
something like

[ahoward@www i686-linux]$ ldd postgres.so
libpq.so.3 => /usr/lib/libpq.so.3 (0x40012000)
libnsl.so.1 => /lib/libnsl.so.1 (0x40027000)
libdl.so.2 => /lib/libdl.so.2 (0x4003c000)
libcrypt.so.1 => /lib/libcrypt.so.1 (0x4003f000)
libm.so.6 => /lib/tls/libm.so.6 (0x4006c000)
libc.so.6 => /lib/tls/libc.so.6 (0x42000000)
libssl.so.4 => /lib/libssl.so.4 (0x4008f000)
libcrypto.so.4 => /lib/libcrypto.so.4 (0x400c4000)
libkrb5.so.3 => /usr/kerberos/lib/libkrb5.so.3 (0x401b5000)
libresolv.so.2 => /lib/libresolv.so.2 (0x40213000)
/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000)

libcom_err.so.3 => /usr/kerberos/lib/libcom_err.so.3 (0x40249000)
libz.so.1 => /usr/lib/libz.so.1 (0x4024b000)

except in your case you will probably see

libpq.so.3 => /usr/local/lib/libpq.so.3 (0x40012000)
^^^^^
^^^^^

that's _ok_, but on many linuxes this dir is NOT in the system search path for
ld.so (cat /etc/ld.so.conf). it MAY be in your environment or it may be set
globally somehow. what i'm saying is that the ruby postgres.so depends on the
linker being able to find the required postgresql libraries at runtime. the
way it does this is by

* standard ld.so search path
* contents of /etc/ld.so.conf
* paths encoded into postgres.so itself
* contents of LD_LIBRARY_PATH

i realize your setup may be slightly different. all i'm saying is be sure the
way the linker finds the postgresql is set in some _global_ way or some users
(say the web using - nobody or www) may have unexpected errors when doing a

require 'postgres'

i'm spewing all this because i spent some time at one point determining the
cause of exactly this problem when all my cgi programs failed to load the
postgres lib. the easiest answer is to

~ > export LD_RUN_PATH=/usr/local/pgsql/lib
~ > ruby extconf.rb --with-pgsql-dir=/usr/local/pgsql \
--with-pgsql-srcinc=/usr/local/src/postgresql-7.4.1/src/include
~ > make
~ > make install

Well, there's our confusion, then. :)

I didn't make pgsql with all headers. The includes directory I was
pointing it was was not (in my case)

/usr/local/pgsql/include/

but rather

/usr/local/src/postgresql-7.4.1/src/include/

If you mean to require that postgresql be installed with all headers for
plruby to build properly, then I think the above needs rewording.

But if it is acceptable--when the user (me) hasn't installed pgsql with
all headers--to point plruby at the headers in the original source
directory for postegresql, then something needs to change slightly in
the header to account for the fact that array.h exists in a sub
'include/server/utils/' directory when installed with pgsql, but is out
in the open in 'include/utils/' in the original source.

Anyhow, all is working now for me. Thanks for a great tool! :)

Well, the next version will test the directory. Just to give you an
example, the include directories for 7.3 and 7.4 are

svg% ls /home/ts/local/pg73/include
ecpgerrno.h ecpgtype.h libpq-fe.h pg_config_os.h postgresql/ sqlca.h
ecpglib.h libpq/ pg_config.h postgres_ext.h sql3types.h
svg%

svg% ls /home/ts/local/pgsql/include
ecpg_informix.h internal/ pg_config_os.h pgtypes_timestamp.h
ecpgerrno.h libpq/ pgtypes_date.h postgres_ext.h
ecpglib.h libpq-fe.h pgtypes_error.h server/
ecpgtype.h pg_config.h pgtypes_interval.h sql3types.h
informix/ pg_config_manual.h pgtypes_numeric.h sqlca.h
svg%

See the directory server and postgresql, the installation was make with
the same commands (I've just given a different directory for --prefix)

The include tree change for each version :-(((
