Hello Steven,
you mention you use CMake with the Yocto (standard) SDK.
After you sourced the SDK environment script, what is the output of
"which cmake" ?
Do you use the cmake toolchain configuration file provided by the SDK?
(CMAKE_TOOLCHAIN_FILE)
In my conf/local.conf I make sure I have a native cmake included in the SDK:
# Does not work, will destroy TOOLCHAIN_HOST_TASK
#TOOLCHAIN_HOST_TASK += "nativesdk-cmake"
# This is a work-around (we need to extra space here because _append
will not add it for us).
TOOLCHAIN_HOST_TASK_append = " nativesdk-cmake"
And this is how I compile an application using SDK and CMake:
(source /tmp/oe-sdk-cmake/environment-setup-core2-64-oe-linux-musl && \
cd myapp-cmake && \
mkdir -p build_sdk && \
cd build_sdk && \
cmake
-DCMAKE_TOOLCHAIN_FILE=$$OECORE_NATIVE_SYSROOT/usr/share/cmake/OEToolchainConfig.cmake
-DCMAKE_VERBOSE_MAKEFILE=1 . .. && \
make)
(I am using gcc, I I will verify this setup if I switch to clang.)
Regards,
--
