Installation fails because only static libcurl searched (dynamic not found)

[dbitouze]

I'm using a Mageia 3 Linux box, which doesn't provide static libraries:

https://wiki.mageia.org/en/Libraries_policy#.2A.la_files https://wiki.mageia.org/en/Packaging_guidelines#Packaging_Static_Libraries

Fedora has the same policy:

https://fedoraproject.org/wiki/Packaging:Guidelines#Packaging_Static_Libraries

But dynamic libraries are provided. For instance, running locate libcurl.so returns:

/usr/lib/libcurl.so
/usr/lib/libcurl.so.4
/usr/lib/libcurl.so.4.3.0

The problem is that pycurl2 installer looks for static library libcurl.a only, so the installation fails. Indeed, running easy_install pycurl2 (as root) returns:

It must be noticed that installing pycurl2, not with easy_install pycurl2, but by cloning the current repository and running, as root, python setup.py install works smoothly.

+1. The same problem with ArchLinux.
