[PATCH] cmake-native: Depend on ncurses-native too

[PATCH] cmake-native: Depend on ncurses-native too

[Mike Crowe]

cmake detects the presence of curses automatically during configure so
cmake-native must also depend on ncurses-native to stop it being removed
from the sysroot during the build.

What does an ncurses enabled cmake give us that is desirable?

I'm not really sure.

CMake's bootstrap configure script detects curses and tries to use it which
causes build failures if curses has gone missing in the meantime.

In the failure I saw bitbake was building cmake-native and ncurses-native
in parallel in a tree that had previously been used to build for a
different machine. This caused curses.h to be present during
cmake-native.do_configure but go missing before or during
cmake-native.do_compile.

It seems to be possible to disable building the "CursesDialog" component to
remove the need for ncurses but I couldn't immediately see how to do that
for a bootstrap build.

The non-native cmake recipe depends on ncurses even though it passes
-DBUILD_CursesDialog=0.

Thanks.

Mike.

I'd much prefer to disable the need for curses if we can since the more
convoluted the dependency chain, the longer our build times. If we don't
need this, it would be much nicer to disable it, even if we have to
patch it out.

Cheers,

Richard

you need to disable it completely in CMakefile.txt, just that define
does not suffice you might try something like

As far as I can tell (by poisoning curses.h in the sysroot) the non-native
cmake build does successfully avoid using curses by specifying
-DBUILD_CursesDialog=0. I have successfully tested removing the
ncurses dependency from the recipe too.

The cmake-native bootstrap procedure means that it is not possible to get
that parameter through to the ultimate cmake native build. So I came up
with this patch:

--- cmake-2.8.12.2/bootstrap~	2014-01-16 17:15:09.000000000 +0000
+++ cmake-2.8.12.2/bootstrap	2014-04-01 21:27:23.841996822 +0100
@@ -1578,6 +1578,7 @@ export MAKE
 
 # Run bootstrap CMake to configure real CMake
 cmake_options="-DCMAKE_BOOTSTRAP=1"
+cmake_options="${cmake_options} -DBUILD_CursesDialog=0"
 if [ -n "${cmake_verbose}" ]; then
   cmake_options="${cmake_options} -DCMAKE_VERBOSE_MAKEFILE=1"
 fi

If I apply this for cmake-native then it also doesn't require curses
(tested with the same poisoning.)

The Gentoo patch may be somewhat safer in the long term because it does a
better job of ensuring that the curses dependency can't come back with
newer cmake versions; it is more likely that the patch would not apply or
the link would fail.

Do you prefer the one line patch above or the Gentoo one?

Thanks.

Mike.

[PATCH 1/2] cmake-native: Stop building ccmake

[Mike Crowe]

The bootstrapped cmake is called in such a way that it will automatically
enable building ccmake if curses is found. This tool isn't particularly
useful to us and it will cause build problems if ncurses-native is built in
parallel with cmake-native so let's just pass -DBUILD_CursesDialog=0 to
disable the feature altogether as the non-native cmake does.

Unfortunately this requires patching the bootstrap script since there
appears to be no way to get this option through.

[PATCH 2/2] cmake: Remove dependency on ncurses

[Mike Crowe]

Commit 2adc9a3f1f1db284f7d91193ad77b3524e0e0d2c stopped ccmake being built
and that is the only part of cmake that relies on curses so we might as
well stop depending on it.

(Tested with a poisoned curses.h to prove that it is unused even if
present.)

It appears that a similar problem occurs if cmake-native is built at the
same time as acl-native:

 Building C object Utilities/cmcurl/CMakeFiles/cmcurl.dir/http_chunks.c.o
 [ 30%] /home/jenkins/workspace/nightly-brightsign-master/MACHINE/source/label/nightly/build-bcm7425/source-release-test-build/brightsign-oe/build-bcm7425/tmp-eglibc/work/x86_64-linux/cmake-native/2.8.12.2-r0/cmake-2.8.12.2/Utilities/cmlibarchive/libarchive/archive_read_disk_entry_from_file.c:38:21:fatal error: sys/acl.h: No such file or directory
 compilation terminated.

cmake detects sys/acl.h but by the time the compiler tries to include it
the file has been unstaged from the sysroot.

This one is harder to patch out. Do you object to me adding acl{,-native}
to DEPENDS?

Thanks.

Mike.

Each dependency we add like this tends to cause slightly longer builds.
Each small piece mounts up. So I do feel quite strongly we disable
things we can...
