Dear Sir, I am trying to install MPICH2-1.5 on a Linux System. It succeeded at the configure step, but when I was building MPICH2, it failed. My information: baoys@altix-1:~> uname -a Linux altix-1 2.6.5-7.244-sn2 #1 SMP Mon Dec 12 18:32:25 UTC 2005 ia64 ia64 ia64 GNU/Linux baoys@altix-1:~> icc -v Version 11.1 baoys@altix-1:~> gcc -v Reading specs from /usr/lib/gcc-lib/ia64-suse-linux/3.3.3/specs Configured with: ../configure --enable-threads=posix --prefix=/usr --with-local-prefix=/usr/local --infodir=/usr/share/info --mandir=/usr/share/man --enable-languages=c,c++,f77,objc,java,ada --disable-checking --libdir=/usr/lib --enable-libgcj --with-gxx-include-dir=/usr/include/g++ --with-slibdir=/lib --with-system-zlib --enable-shared --enable-__cxa_atexit ia64-suse-linux Thread model: posix gcc version 3.3.3 (SuSE Linux) Here are the attachments, including the c.txt and the m.txt(generate by 'make VERBOSE=1 2>&1 | tee m.txt ').
