7f198d6e 57Sorry, I can't find headers or libraries for a supported GUI
574c4fe0
TC
58You need to install development headers and libraries for your GUI
59For Win32: Platform SDK or a substitute
60For X11: X11 headers and libraries, eg. the libX11-dev package on Debian
bc99c241 61For OS X: Install Xcode
