If you want to build this version of SAGA you have to + install the package wxWidgets (also available in Slackbuilds.org). + If you have both wxGTK3 and wxWidgets installed in your system, + make sure that wxWidgets is installed after wxGTK. +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. +3) unixODBC is a required dependency in 32 bit systems since the + libiodbc headers cause a build failure during the compilation. |
