Hello,
I am trying to generate an sdk for a Qt project that includes gRPC. I have
successfully included protobuf compiler (protoc) in the sysroot for the host
which is used by qmake to compile protobuf stubs.
After sourcing the SDK environment protoc is appearing in my PATH and this
allows me to generated client stubs with my proto file. However, when I am
trying to generate server stubs the protoc command requires the grpc_cpp_plugin
path as an argument.
The grpc_cpp_plugin is currently not appearing the host sysroot. Currently, the
plugin seems to be included the in target sysroot but not the host sysroot.
The Qt application recipe currently includes these lines (see grpc-native and
grpc):
DEPENDS = "qtbase qtsensors qtmultimedia sw-mcu grpc-native"
RDEPENDS_${PN} = "qtbase qtsensors qtmultimedia sw-mcu qtvirtualkeyboard
qttranslations qtquickcontrols2 qtgraphicaleffects grpc"
I added the following lines to the image which includes this application:
inherit populate_sdk_qt5
TOOLCHAIN_HOST_TASK_append += "nativesdk-protobuf-compiler"
TOOLCHAIN_TARGET_TASK_append += "grpc"
The command I use to generate the SDK is: bitbake -c do_populate_sdk <image>
I tried to add "grpc" to the TOOLCHAIN_HOST_TASK_append line, bitbake threw
the following error:
* opkg_prepare_url_for_install: Couldn't find anything to satisfy 'grpc'.
Am I misunderstanding how to properly include the plugin or does the current
recipe not support the grpc_cpp_plugin?
Build Configuration:
BB_VERSION = "1.36.0"
BUILD_SYS = "x86_64-linux"
NATIVELSBSTRING = "universal"
TARGET_SYS = "x86_64-poky-linux"
MACHINE = "intel-corei7-64"
DISTRO = "poky"
DISTRO_VERSION = "2.4.2"
TUNE_FEATURES = "m64 corei7"
TARGET_FPU = ""

meta-sbis-app = "rocko:aa9fa139cfc30da53b84c81facd22b958c1f9852"
Note: I had to pull the gRPC recipe from master as it is not included in the
meta-openembedded rocko branch.
Any help is appreciated!

Jacob Kaddoura
