Running Postgresql 7.4.2 on Windows 2000 with Cygwin !

Dear Sirs

I have installed Cygwin (version 1.5.9-1) on my computer
(a K6-2 500Mhz with 256Mb RAM).

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 created an environment-variable called
CYGWIN and have set the value to server

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

/usr/sbin/cygserver

I run this shell-script in a seperate DOS-box.

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

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 ????????????

My E-mail-address is: jan(dot)christensen(at)riva-systems(dot)dk

I hope to hear from you.

Best regards

Jan Christensen
