Hi all.
I need to use a custom target to build of external shared library *.so,
with a custom build system (e.g. using the NDK directly) and to link with.
I faced with a strange behavior of QMAKE_EXTRA_COMPILERS on Android,
which is that the qmake does not creates a "compiler_foo_" target in
the output Makefile for my target if the ANDROID_PACKAGE_SOURCE_DIR is
not set. So, the desired build step does not called at all. O_O
E.g. I have following rules in the *.pro file:
...
android {
foo.name = Foo compiler
foo.input = FOO
foo.output = FOO_PATH
# Build command.
foo.commands = (custom build command)
# Custom additional cleanup targets.
foo.clean += (custom cleanup command)
foo.CONFIG += target_predeps
QMAKE_EXTRA_COMPILERS += foo
# Add the generated library into the resulting apk.
ANDROID_EXTRA_LIBS = $$GST_MODULE_PATH
}
...
In this case I see in Makefile following:
...
compiler_foo_make_all:
compiler_foo_clean:
(set of custom cleanup commands)
...
But, if I try to add any not empty ANDROID_PACKAGE_SOURCE_DIR
to the *.pro file:
...
android {
ANDROID_PACKAGE_SOURCE_DIR = <any value>
....
....
}
...
then the resulting Makefile contains all what need:
...
OBJECTS = <FOO_PATH> ...
...
compiler_gst_make_all: <FOO_PATH>
compiler_gst_clean:
(set of custom cleanup commands)
...
<FOO_PATH>: foo
(set of custom build commands)
...
How can I fix it? Because in a real project I will to use
the QMAKE_EXTRA_COMPILERS in a 'static library' template project,
which does not contains any Android's java sources and so on.
BR,
Denis
