I see that rgdal changed to C++ recently. The issue is in rgdal, because the configure script is missing: CXXFLAGS=`"${R_HOME}/bin/R" CMD config CXXFLAGS` as indicated in Writing R Extensions (note that CPPFLAGS are *not* CXXFLAGS; I say this because it's a common mistake). -- Iñaki Úcar _______________________________________________ R-SIG-Fedora mailing list R-SIG-Fedora@r-project.org https://stat.ethz.ch/mailman/listinfo/r-sig-fedora
