by the way the libwx 3x version is linked to filezilla (oss repo) but filezilla is completely broken :-) filezilla: Symbol `wxTopLevelWindows' has different size in shared object, consider re-linking Fatal Error: Mismatch between the program and library build versions detected. The library used 3.0 (wchar_t,compiler with C++ ABI 1009,wx containers,compatible with 2.8), and your program used 3.0 (wchar_t,compiler with C++ ABI 1010,STL containers,compatible with 2.8). Aborted (core dumped) Now about libwx 3 it seems it help pgadmin3 when linked against it to better support hidpi screen which would be a plus ;-)
