It's not apparent to me how that works at all.
BTW, the .a files being linked to above are not like Unix .a static
archives - they are import library files, which I think they are only
used at link time, not run time. The path to the DLLs isn't being
hardcoded.
Ah, I see. So then what Marco is suggesting is copying a coding
pattern
that does work.
Unless there is further argument I propose to commit something very
like
Marco's suggestion for hstore_plperl, hstore_plpython and
ltree_plpython
No objection here.
OK, I tried the attached patch.
but when trying to build with python 3 I get this (no such problems with
python2, which builds and tests fine):
make -C hstore_plpython all

[cut]
I'd like to get that fixed before applying anything. Marco, any ideas?
To build with python 3, set the environment like this:
PYTHON=/usr/bin/python3 - this can be done in the config file.
I am only building with python2, but on cygwin
there is an additional "intl" library for python3 binding
$ python2-config --libs
-lpython2.7 -ldl
$ python3-config --libs
-lpython3.4m -lintl -ldl
No this doesn't seem to be the problem. For some reason it's apparently
not finding the symbol in plpython3.dll, where it should definitely
exist, unless I'm completely off base. So I'm rather confused.
cheers
