Running Postgresql 7.4.2 on Windows 2000 with Cygwin !

Dear Sirs

I have installed Cygwin on my computer (a K6-2 500Mhz
with 256Mb RAM) and downloaded the file :

cygipc-2.03-2.tar.bz2

and installed the cygipc-daemon in the file.

I have downloaded the file postgresql-7.4.2.tar.gz
and unpacked it and run the following commands:

./configure
make
make install

I have made a shell-script that contains the
following lines:

ipc-daemon2 &
initdb -D /usr/local/pgsql/data
postmaster -i -n -d 2 -D /usr/local/pgsql/data

When I run this shell-script I get the following
error-message from initdb :

FATAL: could not create shared memory
segment: Function not implemented
DETAIL: Failed system call was
shmget(key=1, size=1081344, 03600)
initdb: failed

What is wrong here ???????????
How can I solve this problem ????????????

I hope to hear from you.

Best regards

Jan Christensen
