Getting error when compiling my c++ program

For Developers

I am developing an OpenWRT package
this package compile a Program and compile a C++ program.
When I compile the package I got the following error:

cp -fpR -r /root/source/build_dir/target-mipsel_24kc_musl/bridge_test/bridge_test-3.8.0/bridge_firmware/files/* /root/source/build_dir/target-mipsel_24kc_musl/bridge_test/bridge_test-3.8.0/ipkg-mipsel_24kc/bridge_test/rootfs-overlay/

I added "+libc" and "+libm" in the DEPENDS but this is did not fix the issue

What I am missing ?

I found the cause of the issue.
I was using a Wong c++ compilation. I was using the computer compilator and not the OpenWRT SDK compilator
I had to provide the CXX value to my C++ makefile with this way:

$(MAKE) -C $(PKG_BUILD_DIR)/mycpp debug CC="$(TARGET_CC) -fhonour-copts -DOPENWRT" CXX="$(TARGET_CXX) -DOPENWRT"
