Wow...I have been waiting for the library.  Any chance that I and get
a NPL example?  For example profit maximization?

After discussing this off-line, it turns out that this error message
occurs because your /bin/sh points to /bin/dash (the Debian Almquist
shell), which is a stripped down version of bash. A solution is to
have /bin/sh point to /bin/bash or to specify SHELL=/bin/bash in the
Makefile.

You may get such diff-style output in your makedefs-path after
upgrading because the one in the repository is the one for my machine.

I just committed a new release in which those settings appear in the
private file ~/.nlpy

I am not sure what the problem is. Let's see if this message gets
posted and if you receive it.

I had the same difficulties a few days ago. I manually created the .object
and .module directories. Then , the message [[ not found becomes a warning
since the directory exists, no action being requested then. After, I added
suitable paths to PYTHONPATH, and I added also the Lib path to
LD_LIBRARY_PATH. I also am using Kubuntu 7.10.

Moreover, I had to manually remove spurious lines (looking like output of
some diff command) in 2 or 3 files, among which makedefs-path after getting
the latest cvs version.

Hope this helps.

P.S. Is it possible to **reply** on the list? I had to send a fresh message.

Hi Dmitrey,

Since this is best discussed on the NLPy mailing list, I am replying here.

Are you using Windows? I am not currently supporting it. NLPy has been
tested under Linux and Mac OS/X. If you want to test it under Windows,
I suggest you try either Cygwin or MinGW. I've had success with MinGW
in the past and find it to be a viable alternative.

Cheers,
Dominique
