'found it! The library, which is C code, is built with g++ instead of gcc. As the public function are not declared with the extern "C" construct, their name gets mangled when compiled by g++. I finally understood while reading [1] and thanks to Burcin comments. The problem lies in the library building tools, and has been corrected upstream a year ago. From cddlin changelog: Version 094e (February 7, 2008) / - Thanks to Sven Verdoolaege's fixes, the "configure" script now uses "gcc" as the default compiler, rather than "g++" in earlier releases, and the libraries can be linked properly with both C and C++ programs. Sage uses version 094b, which was released in August 2005. I will file a ticket on trac and try to package the last version. Thank you for your help.
