[postgis-users] About $libdir

[Benjamin Thelen]

Hi,
Thanks for your response. It is confusing. I'll do my best, but I am not
sure whether I understand your answers enough to do the right thing. Here
are a few more questions, if you like to answer.
Thanks!

I understand now.

That would mean, to install postgis I call in
'postgresql-Sourcetree/contrib/postgis/' the gmake like
gmake -L'pg_config --libdir' or gmake -L'pg_config --pkglibdir'? But
somehow, I suppose that is not what you've meant :-). I couldn't find the -L
switch for gmake in the man-page.

I thought postgis is an extentension AND is compiled against postgresql.
This is confusing!
The enabler SQL code is postgis.sql? How do I enable pointing to $libdir?

I'm afraid yes. :-)

I've checked pg_config immediately:

pg_config --libdir --> /usr/local/lib
pg_config --pkglibdir --> /usr/local/lib/postgresql


So it's no surprise, why it did't work, as I used "/usr/local/pgsql/lib". A
little different, isn't it!
That means that libpostgis.so.0 should actually reside in
/usr/local/lib/postgresql? Does the difference come from a compiling error?

I get "mv: No match"?! Differnt Syntax Unix/Linux?
After that postgis.sql will work with $libdir, I suppose.
