1.环境 PC Ubuntu 16.04Raspberry PI4B Ubuntu 18.04 2.交叉工具链接 cd ~ mkdir -p toolchain/raspberrypi git clone git://github.com/raspberrypi/tools.git cd tools/arm-bcm2708 ls -al

可以看到有几套工具链

arm-bcm2708hardfp-linux-gnueabi arm-bcm2708-linux-gnueabi arm-linux-gnueabihf -> arm-rpi-4.9.3-linux-gnueabihf arm-rpi-4.9.3-linux-gnueabihf gcc-linaro-arm-linux-gnueabihf-raspbian gcc-linaro-arm-linux-gnueabihf-raspbian-x64

在这里我们使用的是 arm-linux-gnueabihf 版本

3.安装cmake sudo apt-get install cmake cmake --version

如需升级cmake可以自行查找升级方法

4. 配置toolchain

复制下面文件保存至toolchain/raspberrypi_32.cmake

set(CMAKE_SYSTEM_NAME Linux) set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER) set(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY) set(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY) set(CMAKE_FIND_ROOT_PATH_MODE_PACKAGE ONLY) set(LINUX_COMPILER_FLAGS) set(LINUX_COMPILER_FLAGS_CXX) set(LINUX_COMPILER_FLAGS_DEBUG) set(LINUX_COMPILER_FLAGS_RELEASE) set(LINUX_LINKER_FLAGS) set(LINUX_LINKER_FLAGS_EXE) # STL. set(LINUX_TOOLCHAIN_PATH $ENV{RASPBERRYPI_32_TOOLCHAIN}) list(APPEND CMAKE_FIND_ROOT_PATH "${LINUX_TOOLCHAIN_PATH}") # Sysroot. set(CMAKE_SYSROOT ${LINUX_TOOLCHAIN_PATH}/arm-linux-gnueabihf/sysroot) # Toolchain. set(LINUX_C_COMPILER "${LINUX_TOOLCHAIN_PATH}/bin/arm-linux-gnueabihf-gcc") set(LINUX_CXX_COMPILER "${LINUX_TOOLCHAIN_PATH}/bin/arm-linux-gnueabihf-g++") set(LINUX_ASM_COMPILER "${LINUX_TOOLCHAIN_PATH}/bin/arm-linux-gnueabihf-as") set(CMAKE_C_COMPILER_ID_RUN TRUE) set(CMAKE_CXX_COMPILER_ID_RUN TRUE) set(CMAKE_C_COMPILER_ID Clang) set(CMAKE_CXX_COMPILER_ID Clang) set(CMAKE_C_COMPILER_VERSION 3.8) set(CMAKE_CXX_COMPILER_VERSION 3.8) set(CMAKE_C_STANDARD_COMPUTED_DEFAULT 11) set(CMAKE_CXX_STANDARD_COMPUTED_DEFAULT 98) set(CMAKE_CXX_STANDARD 11) # Generic flags. list(APPEND LINUX_COMPILER_FLAGS -DLINUX -ffunction-sections -funwind-tables -fstack-protector-strong -no-canonical-prefixes) list(APPEND LINUX_LINKER_FLAGS -Wl,--build-id -Wl,--warn-shared-textrel -Wl,--fatal-warnings) list(APPEND LINUX_LINKER_FLAGS_EXE -Wl,--gc-sections -Wl,-z,nocopyreloc) # Debug and release flags. list(APPEND LINUX_COMPILER_FLAGS_DEBUG -g -O0) list(APPEND LINUX_COMPILER_FLAGS_RELEASE -O2) list(APPEND LINUX_COMPILER_FLAGS_RELEASE -DNDEBUG) # Toolchain and ABI specific flags. # Configuration specific flags. # if(LINUX_PIE) set(CMAKE_POSITION_INDEPENDENT_CODE TRUE) list(APPEND LINUX_LINKER_FLAGS_EXE -pie -fPIE) # endif() list(APPEND LINUX_LINKER_FLAGS -Wl,--no-undefined) # Convert these lists into strings. string(REPLACE ";" " " LINUX_COMPILER_FLAGS "${LINUX_COMPILER_FLAGS}") string(REPLACE ";" " " LINUX_COMPILER_FLAGS_CXX "${LINUX_COMPILER_FLAGS_CXX}") string(REPLACE ";" " " LINUX_COMPILER_FLAGS_DEBUG "${LINUX_COMPILER_FLAGS_DEBUG}") string(REPLACE ";" " " LINUX_COMPILER_FLAGS_RELEASE "${LINUX_COMPILER_FLAGS_RELEASE}") string(REPLACE ";" " " LINUX_LINKER_FLAGS "${LINUX_LINKER_FLAGS}") string(REPLACE ";" " " LINUX_LINKER_FLAGS_EXE "${LINUX_LINKER_FLAGS_EXE}") set(CMAKE_C_COMPILER "${LINUX_C_COMPILER}") set(CMAKE_CXX_COMPILER "${LINUX_CXX_COMPILER}") # Set or retrieve the cached flags. # This is necessary in case the user sets/changes flags in subsequent # configures.
