wxGTK3 is part of wxWidgets, a cross-platform API for writing GUI applications on multiple platforms that still utilize the native platform's controls and utilities. webkit2gtk are optional dependencies of this package. This will provide webview support. NOTE: this package is NOT built using --enable-stl by default. if you need to enable stl, use: STL=yes ./wxGTK3.SlackBuild If you need to build static version, use: STATIC=yes ./wxGTK3.SlackBuild When building with static libraries, plugin support will be disabled. This script also auto-detect webkitgtk presence. If it's installed, it will automatically use --enable-webkit parameter. wxGTK3 can be installed alongside with wxGTK/wxPython, but it will overwrite the /usr/bin/wx-config created by wxGTK/wxPython. If you need to build packages using wxGTK/wxPython, simply reinstall the wxGTK/wxPython package and wx-config will point to correct version. The same solution can be used if wxGTK3's wx-config is overwritten. We are in the process of updating all scripts that use wxGTK3 or wxPython to ignore the wx-config symlink at build time, so this will stop being a problem some time in the future.
