As far as I can tell (by poisoning curses.h in the sysroot) the non-native<br>
cmake build does successfully avoid using curses by specifying<br>
-DBUILD_CursesDialog=0. I have successfully tested removing the<br>
ncurses dependency from the recipe too.<br>
<br>
The cmake-native bootstrap procedure means that it is not possible to get<br>
that parameter through to the ultimate cmake native build. So I came up<br>
with this patch:<br>
<br>
--- cmake-2.8.12.2/bootstrap~ 2014-01-16 17:15:09.000000000 +0000<br>
+++ cmake-2.8.12.2/bootstrap 2014-04-01 21:27:23.841996822 +0100<br>

if [ -n "${cmake_verbose}" ]; then<br>
cmake_options="${cmake_options} -DCMAKE_VERBOSE_MAKEFILE=1"<br>
fi<br>
<br>
If I apply this for cmake-native then it also doesn't require curses<br>
(tested with the same poisoning.)<br>
<br>
The Gentoo patch may be somewhat safer in the long term because it does a<br>
better job of ensuring that the curses dependency can't come back with<br>
newer cmake versions; it is more likely that the patch would not apply or<br>
the link would fail.<br>
<br>
Do you prefer the one line patch above or the Gentoo one?<br>
<br>
Thanks.<br>

Mike.<br>
