Re: [cx-oracle-users] libclntsh.so and setup.py

Hi,

> The standard linux/macosx way to look for libraries is to search the LD_LIBRARY_PATH, that is what cx_Oracle should use!

We build py2-cx-oracle RPMs using setup.cfg, with the following sort of thing. This is a bit of a short-hand skeleton which our RPM builder expands to the real spec file, but the following should be the relevant bits. $ORACLE_ROOT is where we put our instant client, the headers are under 'include' and libraries under 'lib'. At the build time, $PATH, $LD_LIBRARY_PATH etc have been set so they include instant client directories (and python, and all other externals we use). %i is where we install into.

I'm actually pretty happy cx-oracle does *not* go poking around the system trying to find things, but instead lets us specify where to find things. It's a bonus if it fails hard if things aren't where we think they should be, so the configuration is guaranteed to be consistent.


%prep
%setup -n cx_Oracle-5.1
%patch -p1

cat >> setup.cfg <<- EOF
[build_ext]
include_dirs = $ORACLE_ROOT/include
library_dirs = $ORACLE_ROOT/lib
EOF

%build
python setup.py build

%install
python setup.py install --prefix=%i

Regards,
Lassi
