Yes (now this test is much more reliable in MPFR 2.2.1). You may have the following problem (quoted from MPFR's INSTALL file): Such problems commonly occur under GNU/Linux machines, where default header and library paths may be inconsistent: gcc is configured to search /usr/local/include by default, while /usr/local/lib is not in the default search paths. If you have a GMP version installed in /usr (provided by the OS) and a new one installed in /usr/local, then the header of the new GMP version and the library of the old GMP version will be used! A typical error is the above one in "make check". The solution is to add /usr/local/include to your C_INCLUDE_PATH and to add /usr/local/lib to your LIBRARY_PATH and LD_LIBRARY_PATH (and/or LD_RUN_PATH), as said above. Alternatively, you can use --with-gmp* configure options (described above), e.g. --with-gmp=/usr/local, but other software that uses GMP and/or MPFR will need correct paths too, and environment variables allow to set them in a global way. -- 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)
