I have been trying to install on the latest version of Mavericks following the instructions in the Therion Wiki by Ladislav Blažek. In a previous attempt there was an error loading VTK with brew so I installed it manually and missed out that step this time. When I came to compile Therion it finished with the following error tclsh mkall.tcl make -C ./loch make[1]: wx-config: Command not found c++ -c -Wall -D_GNU_SOURCE -DLOCH -W -Wall -DLXMACOSX -I/usr/local/include/vtk-5.10 -Wno-deprecated -I/usr/X11R6/include -I/usr/local/Cellar/freetype/2.5.3_1/include/freetype2 -o lxOGLFT.o lxOGLFT.cxx In file included from lxOGLFT.cxx:27: ./lxOGLFT.h:28:10: fatal error: 'wx/wx.h' file not found #include <wx/wx.h> ^ 1 error generated. make[1]: *** [lxOGLFT.o] Error 1 make: *** [loch/loch] Error 2 Dave Clucas daveclucas.com sarawak-caves.com dave.clucas@icloud.com Exploring the World - One cave at a time
