In case you still get the warning after trying that, I think that one can get the same kind of problems when the ABI is incorrect, e.g. a 32-bit GMP library in /usr/lib, a 64-bit GMP library in /usr/local/lib and a MPFR build in the 32-bit ABI (contrary to GMP, MPFR doesn't change the ABI by default): the 64-bit GMP library will be skipped, and the GMP library will be taken from /usr/lib (whereas the gmp.h will still be taken from /usr/local/include). -- Vincent Lefèvre <[EMAIL PROTECTED]> - Web: <http://www.vinc17.org/> 100% accessible validated (X)HTML - Blog: <http://www.vinc17.org/blog/> Work: CR INRIA - computer arithmetic / Arenaire project (LIP, ENS-Lyon)
