It is turned on by default. But swig is used to build our python interface, and there has been a post-5.7.2 fix in the cvs version to make finding swig a _lot_ easier. (Basically, swig just has to be on the PATH in the latest version, and it is much more complicated than that for the 5.7.2 version.) Thus, I suggest you use the cvs version of PLplot for now. > 2) Will PLplot work with Python2.5 on a 64bit linux (AMD64x2)? dunno. > 3) Can user switch between 2 python versions without redoing cmake? I suggest you simply create two different installs of PLplot with different install prefixes to keep the installed versions separate. (Our wiki at http://www.miscdebris.net/plplot_wiki/index.php?title=Main_Page shows you how to specify the install prefix and a whole lot more with cmake.) Also, the two separate builds would somehow have to specify your two separate python versions. Our configuration now simply looks for the python executable so I guess you could shift between your two versions of python by fooling around with a python symlink that points to one or the other. Note the two separate builds and installs would only have to be done once. At python time, you could easily choose which kind of PLplot module you wanted by specifying the appropriate install location. Two separate install locations sounds a bit complicated though, so you may be better off just doing your plotting with a single plplot version using the standard python version you get with the "python" command.
