By trying to emerge kmatplot-0.4-r2 (Gentoo-2004.1 updated two days ago), I noted that the codes as follow did not contained the declaration: #include <cassert> The codes are in /var/tmp/portage/kmatplot-0.4-r2/work/kmatplot-0.4/kmatplot/widgets: qscobject.cpp qsimage.cpp qscontour.cpp qscurve.cpp qsaxes2d.cpp After corrections, #make does not longer produce compilations errors. Therefore it is necessary to go back in /var/tmp/portage/kmatplot-0.4-r2/work/kmatplot-0.4 and according to the INSTALL: ./configure make make install Then $kmatplot enables the access to the graphic plotter sought after.
app-sci/kmatplot has been removed from portage as "obsolete". http://www.gentoo.org/cgi-bin/viewcvs.cgi/app-sci/kmatplot/
