Compiling under Windows with mingw32
====================================
You can compile psycopg under Windows platform with mingw32 compiler. The
software required is:
You can compile psycopg under Windows platform with mingw32
(http://www.mingw.org/) compiler. MinGW is also shipped with IDEs such as
Dev-C++ (http://www.bloodshed.net/devcpp.html) and Code::Blocks
(http://www.codeblocks.org). gcc binaries should be in your PATH.
* MinGW (http://www.mingw.org/). You also get MinGW installed by installing
Dev-C++ IDE (http://www.bloodshed.net/devcpp.html);
You need a PostgreSQL with include and libary files installed. At least v8.0 is required.
* either:
* a binary PostgreSQL installation with include and libary files, at least
release 8.0 (http://www.postgresql.org/download/);
* PostgreSQL sources. You will need to compile PostgreSQL, which also
requires MSYS (http://www.mingw.org/msys.shtml) and Flex and Bison
packages (http://gnuwin32.sourceforge.net/packages.html).
First you need to create a libpython2X.a as described in
http://starship.python.net/crew/kernr/mingw32/Notes.html. Then run:
I assume all the software installed in the standard way. gcc compiler directory
should be in your path.
Steps required to package your own version of psycopg:
1. if building from PostgreSQL binaries:
1.1. create the file libpqdll.a (you should already know how to build
Python extensions with mingw: see
http://starship.python.net/crew/kernr/mingw32/Notes.html for
details):
1.1.1. cd C:\Program Files\PostgreSQL\8.0\lib
1.1.2. pexports C:\WINNT\system32\libpq.dll > libpqdll.def
1.1.3. dlltool --dllname libpq.dll --def libpqdll.def \
--output-lib libpqdll.a
2. else, if building from PostgreSQL source:
2.1. compile it:
2.1.1. unpack postgresql source (ex. in c:\)
2.1.2. run MSYS
2.1.3. cd /c/postgresql-8.0
2.1.4. ./configure --without-zlib
2.1.5. make
2.2. create the file libpqdll.a (dlltool is part of MinGW):
2.2.1. cd postgresql-8.0\src\interfaces\libpq
2.2.2. dlltool --dllname libpq.dll --def libpqdll.def \
--output-lib libpqdll.a
3. build psycopg:
3.1. python setup.py build_ext --compiler=mingw32 install
python setup.py build_ext --compiler=mingw32 install
