# CMake package infrastructure

|
|
|
# This file implements an infrastructure that eases development of
|
|
|
|
|
# package .mk files for CMake packages. It should be used for all
|
|
|
|
|
# packages that use CMake as their build system.
|
|
|
|
|
#
|
|
|
|
|
# See the Buildroot documentation for details on the usage of this

# infrastructure
|
|
|
|
|
#
|
|
|
|
|
# In terms of implementation, this CMake infrastructure requires
|
2014-07-24 20:07:02 +02:00
|
|
|
# the .mk file to only specify metadata information about the
|
2011-01-26 22:18:43 +01:00
|
|
|
# package: name, version, download URL, etc.
|
|
|
|
|
#
|
|
|
|
|
# We still allow the package .mk file to override what the different
|
|
|
|
|
# steps are doing, if needed. For example, if <PKG>_BUILD_CMDS is
|
|
|
|
|
# already defined, it is used as the list of commands to perform to
|
|
|
|
|
# build the package, instead of the default CMake behaviour. The
|
|
|
|
|
# package can also define some post operation hooks.

infra: consistently use double dollar signs inside inner-xxx-targets
The inner-xxx-targets in the buildroot package infrastructures are
evaluated using $(eval) which causes variable references to be a bit
different than in regular make code. As we want most references to be
expanded only at the time of the $(eval) we should not use standard
references $(VAR) but rather use double dollar signs $$(VAR). This includes
function references like $(call), $(subst), etc. The only exception is the
reference to pkgdir/pkgname and numbered variables, which are parameters to
the inner block: $(1), $(2), etc.
This patch introduces consistent usage of double-dollar signs throughout the
different inner-xxx-targets blocks.
In some cases, this would potentially cause circular references, in
particular when the value of HOST_FOO_VAR would be obtained from the
corresponding FOO_VAR if HOST_FOO_VAR is not defined. In these cases, a test
is added to check for a host package (the only case where such constructions
are relevant; these are not circular).
Benefits of these changes are:
- behavior of variables is now again as expected. For example, setting
$(2)_VERSION = virtual in pkg-virtual.mk will effectively work, while
originally it would cause very odd results.
- The output of 'make printvars' is now much more useful. This target shows
the value of all variables, and the expression that led to that value.
However, if the expression was coming from an inner-xxx-targets block, and
was using single dollar signs, it would show in printvars as
VAR = value (value)
while if double dollar signs are used, it would effectively look like
VAR = value (actual expression)
as is intended.
This improvement is for example effective for FOO_DL_VERSION, FOO_RAWNAME,
FOO_SITE_METHOD and FOO_MAKE.
The correctness of this patch has been verified using 'make printvars',
'make manual' and 'make legal-info' before and after applying this patch,
and comparing the output.

pkg-cmake: Skip compilation in installation step
With CMake build system, the "make install" command always compiles
before installing, to make sure that everything is up-to-date.
In Buildroot environment, this is quite useless, because the package
has always already been compiled, either at first build, or when
invoking "make <package>-rebuild".
In all cases, when it comes to staging or target installation step, the
package has just been compiled.
Using "make install/fast" - in order to skip the compilation step - is
therefore more appropriate, more consistent with what other build
systems do, and saves time when you need to rebuild your package.

core: don't build host-cmake if it is available on the build host
Currently all cmake packages depend on host-cmake. Unfortunately
host-cmake takes a long time to configure and build: almost 7 minutes
on a dual-core i5 with SSD. The time does not change even with ccache
enabled.
Indeed, building host-cmake is avoidable if it is already installed on
the build host: CMake is supposed to be quite portable, and the only
patch in Buildroot for the CMake package seems to only affect
target-cmake.
Thus we automatically skip building host-cmake and use the one on the
system if:
- cmake is available on the system and
- it is recent enough.
First, we leverage the existing infrastructure in
support/dependencies/dependencies.mk to find out whether there's a
suitable cmake executable on the system. Its path can be passed in the
BR2_CMAKE environment variable, otherwise it defaults to "cmake". If
it is enabled, found and suitable then we set BR2_CMAKE_HOST_DEPENDENCY
to empty; otherwise we set BR2_CMAKE_HOST_DEPENDENCY to 'host-cmake' and
override BR2_CMAKE with "$(HOST_DIR)/usr/bin/cmake" to revert to using
our own cmake (the old behaviour).
Then in pkg-cmake.mk we replace the hard-coded dependency on host-cmake
to using the BR2_CMAKE_HOST_DEPENDENCY variable, and we use $(BR2_CMAKE)
instead of $(HOST_DIR)/usr/bin/cmake.
Unlike what we do for host-tar and host-xzcat, for host-cmake we do
not add host-cmake to DEPENDENCIES_HOST_PREREQ. If we did, host-cmake
would be a dependency for _any_ package when it's not installed on the
host, even when no cmake package is selected.
Cmake versions older than 3.0 are affected by the bug described and
fixed in Buildroot in ef2c1970e4bf ("cmake: add patch to fix Qt mkspecs
detection"). The bug was fixed in upstream CMake in version 3.0 [0].
Amongst all the cmake packages currently in Buildroot, the currently
highest version mentioned in cmake_minimum_required() is 3.1 (grantlee
and opencv3).
Thus we use 3.1 as the lowest required cmake for now, until a package is
bumped, or a new package added, with a higher required version.

core: don't build host-cmake if it is available on the build host
Currently all cmake packages depend on host-cmake. Unfortunately
host-cmake takes a long time to configure and build: almost 7 minutes
on a dual-core i5 with SSD. The time does not change even with ccache
enabled.
Indeed, building host-cmake is avoidable if it is already installed on
the build host: CMake is supposed to be quite portable, and the only
patch in Buildroot for the CMake package seems to only affect
target-cmake.
Thus we automatically skip building host-cmake and use the one on the
system if:
- cmake is available on the system and
- it is recent enough.
First, we leverage the existing infrastructure in
support/dependencies/dependencies.mk to find out whether there's a
suitable cmake executable on the system. Its path can be passed in the
BR2_CMAKE environment variable, otherwise it defaults to "cmake". If
it is enabled, found and suitable then we set BR2_CMAKE_HOST_DEPENDENCY
to empty; otherwise we set BR2_CMAKE_HOST_DEPENDENCY to 'host-cmake' and
override BR2_CMAKE with "$(HOST_DIR)/usr/bin/cmake" to revert to using
our own cmake (the old behaviour).
Then in pkg-cmake.mk we replace the hard-coded dependency on host-cmake
to using the BR2_CMAKE_HOST_DEPENDENCY variable, and we use $(BR2_CMAKE)
instead of $(HOST_DIR)/usr/bin/cmake.
Unlike what we do for host-tar and host-xzcat, for host-cmake we do
not add host-cmake to DEPENDENCIES_HOST_PREREQ. If we did, host-cmake
would be a dependency for _any_ package when it's not installed on the
host, even when no cmake package is selected.
Cmake versions older than 3.0 are affected by the bug described and
fixed in Buildroot in ef2c1970e4bf ("cmake: add patch to fix Qt mkspecs
detection"). The bug was fixed in upstream CMake in version 3.0 [0].
Amongst all the cmake packages currently in Buildroot, the currently
highest version mentioned in cmake_minimum_required() is 3.1 (grantlee
and opencv3).
Thus we use 3.1 as the lowest required cmake for now, until a package is
bumped, or a new package added, with a higher required version.
