how to include a static library in SDK?

how to include a static library in SDK?

Hello,

I have a recipe that creates a static library. The directory is as follows:
example-staticlib/
example-staticlib/example-staticlib_0.1.bb
example-staticlib/files/
example-staticlib/files/lib.c
example-staticlib/files/lib.h
example-staticlib/files/Makefile

Files content is:


1.     example-staticlib_0.1.bb :

DESCRIPTION = "example stared library"
LICENSE = "LGPLv2"
LIC_FILES_CHKSUM = "file://${COMMON_LICENSE_DIR}/LGPL-2.0;md5=9427b8ccf5cf3df47c29110424c9641a"
SRC_URI = "file://lib.c \
           file://lib.h \
           file://Makefile"
PR = "r0"
S = "${WORKDIR}"
ALLOW_EMPTY_${PN} = "1"
do_install () {
            oe_runmake install DEST=${D}
}
TOOLCHAIN_TARGET_TASK += "example-staticlib-dev"
TOOLCHAIN_TARGET_TASK += "example-staticlib-staticdev"




2.     lib.c
int foo()
{
            return 42;
}



3.     lib.h
int foo();



4.     Makefile
TARGET=libexample.a
all:$(TARGET)
install :
            @install -d $(DEST)/usr/lib/
            @install -m 0644 $(TARGET) $(DEST)/usr/lib/
            @install -d $(DEST)/usr/include/
            @install -m 0644 lib.h $(DEST)/usr/include/
$(TARGET) : lib.c
            $(CC) -c lib.c -o lib.o
            $(AR) rcs $@ lib.o
clean:
            rm -rf lib.o $(TARGET)


When I do:
bitbake core-image-minimal -c populate_sdk
I can see that the library and the header are in build/tmp/sysroot
but when I call the generated script in build/tmp/deploy/sdk/ to install the sdk, I can see that the library is not installed in the sdk sysroot. The header is there, but the static library is not.

I also tried adding this to local.conf:
EXTRA_IMAGE_FEATURES += "staticdev-pkgs"
but that also didn't install the library.

The only thing that worked is:
IMAGE_INSTALL += "example-staticlib-staticdev"
but I would like not to have to do it that way.

So, what exactly do I need to do to get a static library installed in SDK?

Cheers,
Vladimir

That's for regular images, to control the SDK you want SDKIMAGE_FEATURES.
SDKIMAGE_FEATURES_append = " staticdev-pkgs" in the image recipe will get
all static libraries into the SDK.

If you only want this staticdev package, the line above should go into
your *image* recipe, not `example-staticlib`.

Did you ever add:

TOOLCHAIN_TARGET_TASK += "example-staticlib-staticdev"

to core-image-minimal.bb or core-image-minimal.bbappend?

Like Ross stated, if you want *all* staticdev packages, you need to add

SDKIMAGE_FEATURES += "staticdev-pkgs"
