Missing dependencies: Python development files

Asked by bondtnt

Hello,

I have problem with running ./configure script.

Here is output:
............................
checking consistency of all components of python development environment... no
configure: WARNING:
========================================================================
Could not link test program to Python. Maybe the main Python library
has been installed in some non-standard library path. If so, pass it
to configure, via the LDFLAGS environment variable.

Example: ./configure LDFLAGS="-L/usr/non-standard-path/python/lib"

ERROR!
You probably have to install the development version of the Python
package for your distribution. The exact name of this package varies
among them.

One or more library dependencies could not be resolved.

Python development files

Configuration failed. Halt.

  matrix interface ... numpy
  uselocale .......... yes

========================================================================
configure: error: Configuration failure. Halt.

I'm using Ubuntu 10.04 and installed python 2.6 using "apt-get install python".
I've installed devtools using "sudo apt-get install python-all-dev"
but lib folder really did not came up.

Can somebody point me where should I look for lib folder, or what else should be installed?
(I've used locate command but python/lib is really absent in my system)

Best regards and already many thanks for answers

The path is not meant to be interpreted literally; you are not supposed to look for a directory called python/lib. The configure script has found Python, something is wrong with the linking though.

Please post the config.log file.

Here is part of config.log file which is interesting:

Friend of mine suggested to install "libssl-dev" that solved the problem.
