I am using a Yocto recipe to install some binaries and create Python bindings. I received the source code from a vendor, and it is built using CMake. My goal is to create a recipe that will allow the executable files to be installed on an embedded system. My understanding is that an egg file is platform-independent but will package compiled C and C++ files that are platform-specific. So, I set up the toolchain, compile the files, and try to specify Yocto's Python to package the egg file. Here is my recipe:
LICENSE = "CLOSED"
SRC_URI = "file://\*"
DEPENDS += "openssl \
virtual/crypt \
python3-native \
python3-setuptools-native \
python3-cython-native \
zip \
"
S = "${WORKDIR}"
inherit cmake
EXTRA_OECMAKE += "-DPYTHON_EXECUTABLE=${RECIPE_SYSROOT_NATIVE}/usr/bin/python3-native/python3"
FILES\_${PN} += "${S}/build/examples/\*"
do_install() {
install -d ${D}${base_sbindir}
install -m 0755 ${S}/build/examples/\* ${D}${base_sbindir}
}
However, I am getting the following error:
build/tmp/work/aarch64-poky-linux/my-recipe/1.0-r0/recipe-sysroot-native/usr/bin/aarch64-poky-linux/../../libexec/aarch64-poky-linux/gcc/aarch64-poky-linux/9.2.0/ld: cannot find -lpython3.7m | collect2: error: ld returned 1 exit status | error: command 'aarch64-poky-linux-g++' failed with exit status 1 | ninja: build stopped: subcommand failed. | WARNING: exit code 1 from a shell command.
However, when I search for "libpython3.7m.so", I can find the file at:
ls tmp/work/aarch64-poky-linux/sls37/1.0-r0/recipe-sysroot-native/usr/lib/libpyth on\* tmp/work/aarch64-poky-linux/sls37/1.0-r0/recipe-sysroot-native/usr/lib/libpython3.7m.so tmp/work/aarch64-poky-linux/sls37/1.0-r0/recipe-sysroot-native/usr/lib/libpython3.7m.so.1.0 tmp/work/aarch64-poky-linux/sls37/1.0-r0/recipe-sysroot-native/usr/lib/libpython3.so
Could someone help me figure out what is causing this issue?
I check the build log, and I can find "build/tmp/work/aarch64-poky-linux/sls37/1.0-r0/recipe-sysroot-native/usr/lib" with "-L" in the compile parameters.
