Dear Santu, You can follow this guide http://alps.comp-phys.org/mediawiki/index.php/Building_ALPS_from_source to build ALPS from source. Follow your file structure, after `cd build` you can try: `cmake -DBoost_ROOT _DIR:PATH=/home/cces/Downloads/ALPS/alps-2.2.b4-src-with-boost/boost /home/cces/Downloads/ALPS/alps-2.2.b4-src-with-boost/alps` And the dependent libraries need also be installed carefully. If you meet any problems, please let me know.

I installed required python packages python2.7. I then untar by tar -xvzf alps-2.2.b4-src-with-boost.tar.gz Then mkdir build Then cd build Then cmake -DCMAKE_INSTALL_PREFIX=/home/cces/Downloads/ALPS/alps-2.2.b4-src-with-boost/alps/ .. I got an error. I tried different ways too using conda install but it did not work. So, I thought to build from source in linux as suggested in some websites. I have attached the Log file of the error. Can anyone please help me to install the alps in linux pc. I sent this mail before but I found there was an issue with maximum size of mail. So I have attached only one error file. Thanking you, Santu
