In addition, if you compile the MongoDB source code, you need to download the dependency package ftp://ftp.mozilla.org/pub/mozilla.org/js/js-1.7.0.tar.gzmake-F makefile. refjs_dist =/usr make-F makefile. ref export compile MongoDB and installtar-xvf mongodb-src-r1.4.4.tar.gzcd mongodb-src-r1.4.4scons -- Full Install also if you do not have a boost library, you also need to install boost |. /Bootstrap. sh->. /bjam install -- prefix =/usr/local after all the installations are completed, the corresponding MongoDB files will be available in/usr/loca include and libl.
