Hello, I am compiling alps2.0.0-- -r5363 on a linux machine (fedora) with intel compilers and mkl I use boost provided by alps. python version is 2.6.4 the cmake command is as follows: cmake -D Boost_ROOT_DIR:PATH=~/alps/alps-2.0.0-r5363-src-with-boost/boost -DCMAKE_INSTALL_PREFIX=~/alps/alps-2.0.0-r5363 -D LAPACK_64_BIT=ON -DLPSOLVE_ROOT=~/alps/lp_solve_4.0 ~/alps/alps-2.0.0-r5363-src-with-boost/alps cmake, make, make test, all went fine. however, I got the following error during the install: CMake Error at lib/pyalps/cmake_install.cmake:41 (FILE): file INSTALL cannot find "/home/gremaud/alps/alps-2.0.0-r5363/lib/pyalps/pyalea_c.so". Call Stack (most recent call first): cmake_install.cmake:94 (INCLUDE) I checked that before the installation the file pyalea_c.so existed. Strangely enough, after the preceding error, it has disappeared. any clue of what happened? regards, Benoît Grémaud -------------------- Researcher at CNRS, Laboratoire Kastler Brossel (Paris, France) Visiting Associate Professor at the Centre for Quantum Technologies (NUS, Singapore)
