Hi, I just ran a test build on my system. I uninstalled the Eigen2 library, and run cmake in an empty directory. It printed that
-- Could NOT find Eigen2 (missing: EIGEN2_INCLUDE_DIR EIGEN2_VERSION_OK) but it successfully created the build environment and then a build also completed successfully, without Eigen2. If on your system you are unable to compile ktechlab when you don't have Eigen2 installed, than it's a buildsystem bug. Best regards, Zoltan P.S: by mistake I also sent an empty response email to the list; please ignore it On Sat, 19 Nov 2011 08:36:24 +0100, Slavko <slav...@slavino.sk> wrote: > hi, > > Dňa Wed, 16 Nov 2011 10:41:43 +0100 Zoltan Padrah > <zoltan.pad...@gmail.com> napísal: > >> the readme file for ktechlab source tree is mostly completed: >> >> http://ktechlab.git.sourceforge.net/git/gitweb.cgi?p=ktechlab/ktl-zoltan_p;a=blob;f=README;hb=HEAD >> >> https://github.com/ktechlab/ktechlab/blob/new-gui/README > > i tried to folow build instructions.
