[vtk-developers] python, postgreSQL, VTK build

[Darren Weber]

I downloaded libpqxx-2.6.9.tar.gz and build in /usr/src/libpqxx-2.6.9

Before doing anything, we have /usr/src/pqxx-2.6.9/include/pqxx/config.h.inwith:

/* Define if the compiler supports the standard "long double" type */
#undef PQXX_HAVE_LONG_DOUBLE

/* Define if the compiler supports "long long" types */
#undef PQXX_HAVE_LONG_LONG

I then prepare to run 'configure' to ensure it can find pg_config, as:

# export PATH=${PATH}:/Library/PostgreSQL/8.3/bin
# which pg_config
/Library/PostgreSQL/8.3/bin/pg_config

I then run configure:

After 'configure --enable-shared' there is include/pqxx/config.h

/* Define if the compiler supports the standard "long double" type */
#define PQXX_HAVE_LONG_DOUBLE 1

/* Define if the compiler supports "long long" types */
#define PQXX_HAVE_LONG_LONG 1

So it looks like it's enabled.  I then run:

# make
# make install

That takes care of the shared library for pqxx:

[ root at elegans /usr/src/libpqxx-2.6.9 ]# ll /usr/local/lib/libpqxx*
-rwxr-xr-x 1 root wheel 464K 2008-08-29 15:49
/usr/local/lib/libpqxx-2.6.9.dylib*
-rwxr-xr-x 1 root wheel 475K 2008-08-28 15:37
/usr/local/lib/libpqxx-3.0.0.dylib*
-rw-r--r-- 1 root wheel 3.8M 2008-08-29 15:49 /usr/local/lib/libpqxx.a
lrwxr-xr-x 1 root wheel   19 2008-08-29 15:49 /usr/local/lib/libpqxx.dylib
-> libpqxx-2.6.9.dylib*
-rwxr-xr-x 1 root wheel  863 2008-08-29 15:49 /usr/local/lib/libpqxx.la*
[ root at elegans /usr/src/libpqxx-2.6.9 ]#


I still have a 3.0 dylib, but the default symlink points to the 2.6.9
version, so that should be fine.

A thousand thanks!  (What's next? Oh yea, back to building VTK with PGSQL!)
