Some qmake based packages need to call the syncqt.pl script before building to have a properly populated "include" directory inside the package build tree. This script is normally automatically executed by qmake when a source tree is from a git clone: buildroot purges the .git directory hence the script never runs, and we need to call it explicitly. Setting <pkg>_SYNC_QT_HEADERS = YES will force calling this script. Signed-off-by: Angelo Compagnucci <angelo@amarulasolutions.com> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com>

==== +qmake-package+ tutorial
|
|
|
|
First, let's see how to write a +.mk+ file for a QMake-based package, with
|
|
an example :
|
|
|
|
------------------------
|
|
01: ################################################################################
|
|
02: #
|
|
03: # libfoo
|
|
04: #
|
|
05: ################################################################################
|
|
06:
|
|
07: LIBFOO_VERSION = 1.0
|
|
08: LIBFOO_SOURCE = libfoo-$(LIBFOO_VERSION).tar.gz
|
|
09: LIBFOO_SITE = http://www.foosoftware.org/download
|
|
10: LIBFOO_CONF_OPTS = QT_CONFIG+=bar QT_CONFIG-=baz
|
|
11: LIBFOO_DEPENDENCIES = bar
|
|
12:
|
|
13: $(eval $(qmake-package))
|
|
------------------------
|
|
|
|
On line 7, we declare the version of the package.
|
|
|
|
On line 8 and 9, we declare the name of the tarball (xz-ed tarball
|
|
recommended) and the location of the tarball on the Web. Buildroot
|
|
will automatically download the tarball from this location.
|
|
|
|
On line 10, we tell Buildroot what options to enable for libfoo.
|
|
|
|
On line 11, we tell Buildroot the dependencies of libfoo.
|
|
|
|
Finally, on line line 13, we invoke the +qmake-package+
|
|
macro that generates all the Makefile rules that actually allows the
|
|
package to be built.
|
|
|
|
[[qmake-package-reference]]
|
|
|
|
==== +qmake-package+ reference
|
|
|
|
The main macro of the QMake package infrastructure is +qmake-package+.
|
|
It is similar to the +generic-package+ macro.
|
|
|
|
Just like the generic infrastructure, the QMake infrastructure works
|
|
by defining a number of variables before calling the +qmake-package+
|
|
macro.
|
|
|
|
First, all the package metadata information variables that exist in
|
|
the generic infrastructure also exist in the QMake infrastructure:
|
|
+LIBFOO_VERSION+, +LIBFOO_SOURCE+, +LIBFOO_PATCH+, +LIBFOO_SITE+,
|
|
+LIBFOO_SUBDIR+, +LIBFOO_DEPENDENCIES+, +LIBFOO_INSTALL_STAGING+,
|
|
+LIBFOO_INSTALL_TARGET+.
|
|
|
|
An additional variable, specific to the QMake infrastructure, can
|
|
also be defined.
|
|
|
|
* +LIBFOO_CONF_ENV+, to specify additional environment variables to
|
|
pass to the +qmake+ script for the configuration step. By default, empty.
|
|
|
|
* +LIBFOO_CONF_OPTS+, to specify additional options to pass to the
|
|
+qmake+ script for the configuration step. By default, empty.
|
|
|
|
* +LIBFOO_MAKE_ENV+, to specify additional environment variables to the
|
|
+make+ command during the build and install steps. By default, empty.
|
|
|
|
* +LIBFOO_MAKE_OPTS+, to specify additional targets to pass to the
|
|
+make+ command during the build step. By default, empty.
|
|
|
|
* +LIBFOO_INSTALL_STAGING_OPTS+, to specify additional targets to pass
|
|
to the +make+ command during the staging installation step. By default,
|
|
+install+.
|
|
|
|
* +LIBFOO_INSTALL_TARGET_OPTS+, to specify additional targets to pass
|
|
to the +make+ command during the target installation step. By default,
|
|
+install+.
|
|
|
|
* +LIBFOO_SYNC_HEADERS+, to run syncqt.pl before qmake. Some packages
|
|
need this to have a properly populated include directory before
|
|
running the build.
