Hi,
I’m trying to cross compile a project on windows using visual studio:
cmake -G “Visual Studio 17 2022” -A ARM -DCMAKE_TOOLCHAIN_FILE=C:/CMAKE_sample/toolchain/toolchain_windows.cmake …
this is my toolchain file:
INCLUDE(CMakeForceCompiler)
message(STATUS "toolchain windows called")
#SET(CMAKE_ECLIPSE_VERSION 4.22.0)
set(CMAKE_VERBOSE_MAKEFILE ON)
# this one is important
SET(CMAKE_SYSTEM_NAME Linux)
#this one not so much
SET(CMAKE_SYSTEM_VERSION 1)
SET(CMAKE_SYSTEM_PROCESSOR arm)
#set(CMAKE_C_COMPILER_WORKS 1)
# https://releases.linaro.org/components/toolchain/binaries/4.9-2016.02/arm-linux-gnueabihf/gcc-linaro-4.9-2016.02-i686-mingw32_arm-linux-gnueabihf.tar.xz
SET(TOOLCHAIN_ROOT_PATH C:/vendors/toolchains/windows/gcc-linaro-4.9-2-mingw32_arm-linux-gnueabihf)

# where is the target environment
SET(CMAKE_FIND_ROOT_PATH ${TOOLCHAIN_ROOT_PATH})
#set (CMAKE_FIND_ROOT_PATH ${CMAKE_FIND_ROOT_PATH} "${TRUNK}/${TOOLCHAIN_SYS_PATH}"))

It looks like that visual studio is not using my toolchain;
– The C compiler identification is MSVC 19.32.31329.0
– Detecting C compiler ABI info
– Detecting C compiler ABI info - done
– Check for working C compiler: C:/Program Files/Microsoft Visual Studio/2022/Professional/VC/Tools/MSVC/14.32.31326/bin/Hostx64/arm/cl.exe - skipped
