Hello,
I've managed to install nlopt-2.1.2 with Python bindings
However, there have been some issues.
I'm using Linux (Ubuntu), Python 2.6
The shell command I ran successfully is:
b45...@shlp:/tmp/nlopt-2.1.2$ ./configure
--prefix=/home/b45ch1/workspace/tmp/nlopt-2.1.2 --enable-shared
Python=python && make && sudo make install
1) for some reason I needed root access:
if I run simply
$ make install
I get the error:
...

2) Another issue is that the files are written to
lib/python2.6/site-packages
However, on my ubuntu machine I only have
/usr/lib/python2.6/dist-packages
i.e. there is no site-packages, which results in an error when installing with
./configure --enable-shared Python=python && make && install
3) I think it would be nice if you could make a package
nlopt/
__init__.py
nlopt.py
_nlopt.so
or similar. At the moment, the site-packages gets cluttered with many files
b45...@shlp:~/workspace/tmp/nlopt-2.1.2/lib/python2.6/site-packages$ ls
_nlopt.a nlopt.py nlopt.pyo _nlopt.so.0
_nlopt.la nlopt.pyc _nlopt.so _nlopt.so.0.4.2
4) It would be nice if nlopt.py had a docstring that gives a simple
example that helps you get started:
In [7]: import nlopt
In [8]: nlopt?
Type: module
Base Class: <type 'module'>
String Form: <module 'nlopt' from
'/home/b45ch1/workspace/tmp/nlopt-2.1.2/lib/python2.6/site-packages/nlopt.py'>
Namespace: Interactive
File:
/home/b45ch1/workspace/tmp/nlopt-2.1.2/lib/python2.6/site-packages/nlopt.py
Docstring:
<no docstring>
best regards,
Sebastian
