Schooner,
could you please direct me how to install Qt 5 on LinuxCNC Lucid. As I
understood, I have to install lightdm first.
I tried to get and install lightdm binaries, but failed, then tried to
compile it from sources, no success too - I got an error:
checking for LIGHTDM... no
configure: error: Package requirements (
glib-2.0 >= 2.30
gio-2.0 >= 2.26
gio-unix-2.0
xdmcp
xcb
) were not met:
Requested 'glib-2.0 >= 2.30' but version of GLib is 2.24.1
Requested 'gio-2.0 >= 2.26' but version of GIO is 2.24.1
Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.
Alternatively, you may set the environment variables LIGHTDM_CFLAGS
and LIGHTDM_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
