Dear Prof. Troyer, Thanks for your advice on not building alps in /opt/alps. I mistook the instruction on making a build directory to mean that both the build stage and the the install stage can be in the same directory, in my case /opt/alps. I have corrected this and I am in the process of building and installing alps on my system, now. Best regards, Henry K.

Dear Prof. Troyer, Thanks for the prompt response to my mail. Yes, as advised in Bauer, et al (2011). I built Alps in /opt/alps using the Cmake3.0 Gui. The build process did not report any error until the make test stage and the subsequent make install stage where I got the error messages I reported earlier. As you suggested, I, actually, ignored the warning on the Numpy API. Thank you. Best regards, Henry Otobrise Dept. Of Physics, Obafemi Awolowo University, Ile-Ife.

Dear All, After waiting for the release of the Windows installer for the latest Alps 2.2.b4 version without success, I have eventually resolved to to build Alps from source on a Linux (Ubuntu 15.04) Os. However, I have some challenges that *I hope this platform can assit me with;*

*1.) I am installing the Alps 2.2.b4 version using cmake-gui. However, I kept getting the following error messages after what looked like a successful make process when I*

*i) 'make test':The following tests FAILED: 115 - expression (Failed)Errors while running CTestMakefile:137: recipe for target 'test' failedmake: *** [test] Error 8 *

*and when I disregard the error from the 'make test' to*

*ii) 'make install':*

*CMake Error at lib/pyalps/cmake_install.cmake:490 (file): file INSTALL cannot find "/opt/alps/lib/pyalps/pyalea_c.so".Call Stack (most recent call first): cmake_install.cmake:131 (include)Makefile:66: recipe for target 'install' failedmake: *** [install] Error 1* Kindly advise on how to resolve these problems. 2.) While building Alps (i.e. while running make), I kept getting the warning; using deprecated Numpy API, disable it by" "#defining NPY_NO_DEPRECATED_API NPY_1_7_API_VERSION" [-wcpp]. Do I just ignore the warning or is there some thing I should do?
