Installing PostgreSQL on NT: --------------------------------------------------------------------------- It can be done by done by typing configure, make and make install. 1. Install the Cygwin package 2. Update to EGCS 1.1.2 (This may be optional.) --------------------------------------------------------------------------- OPTIONAL 1. Install the Andy Piper Tools (http://www.xemacs.freeserve.co.uk/) (This may be optional.) You need at least the crypt library (also available as ftp://sourceware.cygnus.com/pub/cygwin/xfree/libcrypt-cygwin-b20.1.tar.bz2) --------------------------------------------------------------------------- CYGWIN32 INSTALLATION 1. Download the Cygwin32 IPC Package by Ludovic LANGE http://www.multione.capgemini.fr:80/tools/pack_ipc/current.tar.gz 2. Untar the package and follow the readme instructions. 3. Apply the patch at the end of this file to the cygipc sources before compiling the library. 4. I tested 1.03. 5. I used the \cygwin-b20\h-i568-cygwin32\i586-cygwin32\lib and \cygwin-b20\h-i568-cygwin32\i586-cygwin32\include\sys instead of the /usr/local/lib and usr/local/include/sys. NOTE: Also, the cygnus-bindir has to be placed in the path before the NT-directories, because the sort.exe has to be taken for cygnus, not NT. --------------------------------------------------------------------------- POSTGRESQL INSTALL WITH NT SPECIFICS 1. Download the current version of PostgreSQL. 2. Untar the package. 3. Copy the files from \pgsql\src\win32 according to the readme file. 4. Edit \pgsql\src\template\cygwin32 if needed (I had to adjust the YFLAGS path). 5. ./configure 6. make 7. create the directory /usr/local/pgsql manually: the mkdir cannot create a directory 2 levels deep in one step. 8. make install 9. cd /usr/lical/pgsql/doc 10. make install 11. Set the environmental data 12. Initdb --username=jkr (do not run this command as administrator) 13. Open a new Cygwin command prompt 14. Start "ipc-deamon&" (background proces) 15. Start "postmaster -i 2>&1 > /tmp/postgres.log &" (background proces) 16. Start "tail -f /tmp/postgres.log" to see the messages 17. cd /usr/src/pgsql/src/test/regress 18. make all runtest All test should be run. NOTE: By default, PostgreSQL clients like psql communicate using unix domain sockets, which don't work on NT. Start the postmaster with -i, and when connecting to the database from a client, set the PGHOST environment variable to 'localhost' or supply the hostname on the command line.
