Yocto recipe to compile C++ program with usb.h include

I would like to compile a c++ program in my yocto toolchain. For this, I added a new recipe that should compile the program and install it into the image.

My issue is that I have to include some kernel headers like `usb.h``

recipe.bb

SUMMARY = "Simple helloworld application"
SECTION = "examples"
LICENSE = "MIT"
LIC_FILES_CHKSUM = "file://${COMMON_LICENSE_DIR}/MIT;md5=0835ade698e0bcf8506ecda2f7b4f302"

SRC_URI += "file://dcdc-nuc.h \
           file://dcdc-nuc.cpp \
           file://dcdc-nuc-console.cpp \
           "

S = "${WORKDIR}"

TARGET_CC_ARCH += "${LDFLAGS}"

do_compile() {
         ${CXX}  ${BUILD_CXXFLAGS}  dcdc-nuc-console.cpp -o dcdc-nuc
}

do_install() {
         install -d ${D}${bindir}
         install -m 0755 dcdc-nuc ${D}${bindir}
}

Current message


| In file included from dcdc-nuc-console.cpp:23:
| dcdc-nuc.h:23:10: fatal error: linux/usb.h: No such file or directory
|    23 | #include <usb.h>
|       |          ^~~~~~~
| compilation terminated.
| WARNING: exit code 1 from a shell command.

I know that I have to make the compile aware of the kernel headers but I'm not able to find any hint on how to do this. Thanks for all the help in advance!

I believe you need to add libusb as a dependence to your recipe.

Add the following line to your recipe:

DEPENDS = "libusb"
