need. Luckily, the configure output is pretty good about telling you about any tools you need to update. +From some experimentation, here's a list of pre-requisite RPMs necessary for a UW-style build on RHEL6 as of version 7.9.6: +*: libicu +*: boost +*: boost-test +*: pcre-devel +*: keyutils-libs-devel +*: krb5-libs +*: openssl-devel +*: uuid-devel +*: uuid-c++-devel +*: libuuid-devel +*: libxml2 +*: pam-devel +*: zlib +*: cmake-2.8.X. NOTE: RHEL6 ships with cmake-2.6 which does NOT work. The OSG hosts a compilation of cmake-2.8.4 here - http://koji-hub.batlab.org/mnt/koji/packages/cmake/2.8.4/2.osg.el6/x86_64/cmake-2.8.4-2.osg.el6.x86_64.rpm +*: libtool-ltdl-devel +*: libtool +*: glibc-static +*: byacc +*: libX11-devel {section: Getting the source}
