Hi all. I am trying to compile the latest version of scilab, Scilab-3.1-rc1 from source. The configurator seems to have trouble locating the tcl and tk libraries, which I know exist as '/usr/lib64/tcl8.4' and '/usr/lib/tk8.4' (I am running SuSE 9.2 for AMD64 and I updated them via apt for SuSE). My kernel is 2.6.11-4. Here is part of the configurator output, pertaining to these two libraries: checking for main in -ldl... no checking for header file tcl.h... found in /usr/include checking if tcl is version 8.4 or later... cc: unrecognized option `-R/usr/X11R6/lib64' cc1: error: bad value (athlon64) for -march= switch cc1: error: bad value (athlon64) for -mcpu= switch (can't happen) yes checking for tcl library tcl.... found in /usr/include checking if tcl is version 8.4 or later... cc: unrecognized option `-R/usr/X11R6/lib64' cc1: error: bad value (athlon64) for -march= switch cc1: error: bad value (athlon64) for -mcpu= switch (can't happen) yes checking for tcl library tcl.... configure: error: header file tcl.h has been found for 8.4* but no corresponding tcl library Any ideas?
