This seems to point to an incompatibility between your compiler and the machine you are running it on. Please make sure that you use a very recent compiler and assembler. You can find more answers about this issue - which is not related to ALPS - by searching the web for the error message below

Hi All

I am installing ALPS on my Server with 64 bit processor arcitecture and the version I using is alps-2.2.b3-r7462-src-with-boost.tar.gz http://alps.comp-phys.org/static/software/releases/alps-2.2.b3-r7462-src-with-boost.tar.gz . And I am encountering this error each time I try installing it. The last part of my error information is given below. Please suggest. "Linking CXX shared module mpi_c.so [ 39%] Built target mpi_c Scanning dependencies of target alps [ 39%] Building CXX object src/alps/CMakeFiles/alps.dir/utility/encode.cpp.o [ 39%] Building CXX object src/alps/CMakeFiles/alps.dir/utility/copyright.cpp.o [ 39%] Building CXX object src/alps/CMakeFiles/alps.dir/utility/os.cpp.o [ 39%] Building CXX object src/alps/CMakeFiles/alps.dir/utility/temporary_filename.cpp.o [ 40%] Building CXX object src/alps/CMakeFiles/alps.dir/utility/vmusage.cpp.o [ 40%] Building CXX object src/alps/CMakeFiles/alps.dir/alea/nan.C.o [ 40%] Building CXX object src/alps/CMakeFiles/alps.dir/alea/observable.C.o [ 40%] Building CXX object src/alps/CMakeFiles/alps.dir/alea/observablefactory.C.o . . . . /tmp/ccE1HDpC.s:234080: Error: no such instruction: `vfmadd312sd 56(%rbx),%xmm2,%xmm0' make[2]: *** [src/alps/CMakeFiles/alps.dir/alea/observablefactory.C.o] Error 1 make[1]: *** [src/alps/CMakeFiles/alps.dir/all] Error 2 make: *** [all] Error 2"

For information, I have installed the same version on my other servers with similar architecture.

Suggestions would be of real help.

Thanks Swagata
