If you want to build this version of SAGA you have to + install the package wxWidgets (also available in Slackbuilds.org). +2) SAGA requires an ODBC driver in the system. It works both with + iODBC (installed with the libiodbc package (included in Slackware + 15.0) and unixODBC (installed from the SBo's slackbuild). The build + first searches for unixODBC then for iODBC. It fails if any driver + is found. These drivers are in conflict so, if you have installed + and then removed unixODBC, please make sure to reinstall libiodbc. + You should also consider that a package prebuilt in a Slackware + with unixODBC should not be installed in a system with iODB (and + vice versa). |
