Sir/Madam, I have sent you a mail regarding this,but I think I forgot to include somethings that you may require:- 1.GMP Version Number:- GMP-4.2.2 (latest one) 2.Problem is that I am not able to compile library. The make does not complete.I gave it two commands (1)./configure --enable-cxx --disable-shared and then (2) make but it gave an error,output of make as well as configure is attached to this email. 3. gcc version is 4.1.3 and output of command gcc -v is   "Using built-in specs. Target: i486-linux-gnu Configured with: ../src/configure -v --enable-languages=c,c++,fortran,objc,obj-c++,treelang --prefix=/usr --enable-shared --with-system-zlib --libexecdir=/usr/lib --without-included-gettext --enable-threads=posix --enable-nls --with-gxx-include-dir=/usr/include/c++/4.1.3 --program-suffix=-4.1 --enable-__cxa_atexit --enable-clocale=gnu --enable-libstdcxx-debug --enable-mpfr --enable-checking=release i486-linux-gnu Thread model: posix gcc version 4.1.3 20070929 (prerelease) (Ubuntu 4.1.2-16ubuntu2)" 4.output of uname -a is "Linux vaneet-laptop 2.6.22-14-generic #1 SMP Sun Oct 14 23:05:12 GMT 2007 i686 GNU/Linux" 5.Output of ./config.guess is "core2-pc-linux-gnu" and output of ./configfsf.guess is "i686-pc-linux-gnu". You can find some other files that you may need that are the outputs for the ./configure and make commands resp. If I am doing something wrong then please let me know. Please reply as soon as possible. -- Thank you and best regards, Vaneet Dadra <a href="http://www.cse.iitd.ac.in/~cs1060188">www.cse.iitd.ac.in/~cs1060188</a>
