基于buildroot 编译工具链交叉编译evest-core
编译步骤
cmake 交叉编译配置文件cross.cmake
文件中set(TOOLCHAIN_PATH /home/wyq/stm32/buildroot/output/host)需要改成ubuntu中工具链的位置，
cross.cmake文件放在everest-core下
set(CMAKE_SYSTEM_NAME Linux)
set(CMAKE_SYSTEM_PROCESSOR arm)
set(CMAKE_VERBOSE_MAKEFILE ON)
set(TOOLCHAIN_PATH /home/wyq/stm32/buildroot/output/host)
set(CMAKE_C_COMPILER ${TOOLCHAIN_PATH}/bin/arm-buildroot-linux-gnueabihf-gcc)
set(CMAKE_CXX_COMPILER ${TOOLCHAIN_PATH}/bin/arm-buildroot-linux-gnueabihf-g++)
set(CMAKE_FIND_ROOT_PATH ${TOOLCHAIN_PATH}/arm-buildroot-linux-gnueabihf/sysroot/)
# for libraries and headers in the target directories
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(Python3_NO_SYSTEM_PATHS ON)
set(Python3_EXECUTABLE ${TOOLCHAIN_PATH}/usr/bin/python3.11)
set(Python3_FIND_REGISTRY NEVER)
set(Python3_FIND_STRATEGY "LOCATION")
set(Python3_INCLUDE_DIR ${TOOLCHAIN_PATH}/usr/include/python3.11)
set(Python3_LIBRARIES ${TOOLCHAIN_PATH}/usr/lib/x86_64-linux-gnu/libpython3.10.so.1.0)
set(Python3_LIBRARY_DIRS ${TOOLCHAIN_PATH}/usr/lib/x86_64-linux-gnu)
#set(Python3_RUNTIME_LIBRARY_DIRS ${TOOLCHAIN_PATH}/../target/usr/lib)
set(NODEJS_INCLUDE_DIR ${TOOLCHAIN_PATH}/usr/include/node)
set(Boost_INCLUDE_DIR ${TOOLCHAIN_PATH}/arm-buildroot-linux-gnueabihf/sysroot/usr/include)
set(Boost_LIBRARY_DIR ${TOOLCHAIN_PATH}/arm-buildroot-linux-gnueabihf/sysroot/usr/lib)
set(Boost_NO_SYSTEM_PATHS ON)
#set(Boost_ADDITIONAL_VERSIONS "1.80.0")
make
//执行cmake命令
[~/dev/everest/workspace/everest-core/build]$ cmake -DCMAKE_TOOLCHAIN_FILE=../cross.cmake -D_DEBUG=ON -DCMAKE_BUILD_TYPE=MinSizeRel -DEVEREST_ENABLE_PY_SUPPORT=OFF ..
//然后执行make，12是根据自己ubuntu的cpu核数来，加速编译
[~/dev/everest/workspace/everest-core/build]$ make -j12 install
//编译完成会在build下生成dist目录
[~/dev/everest/workspace/everest-core/build]$ ls

CMakeFiles CPM_modules dist_strip install_manifest.txt run-scripts
cmake_install.cmake cpm-package-lock.cmake Doxyfile.doxygen-everest-core lib 裁剪符号表
由于设备空间问题，需要进一步裁剪文件的符号表，将strip.sh放在everest-core下，文件内容为
#!/bin/bash
# 检查参数数量
if [ "$#" -ne 3 ]; then
echo "Usage: $0 <source_directory> <destination_directory> <strip_path>"
exit 1
fi
# 获取参数
SOURCE_DIR="$1"
DEST_DIR="$2"
STRIP_PATH="$3"
# 检查源目录是否存在
if [ ! -d "$SOURCE_DIR" ]; then
echo "Error: Source directory $SOURCE_DIR does not exist."
exit 1
fi
# 检查strip是否是可执行文件
if [ ! -x "$STRIP_PATH" ]; then
echo "Error: Specified strip path $STRIP_PATH is not an executable."
exit 1
fi
# 拷贝目录A到目录B
echo "Copying $SOURCE_DIR to $DEST_DIR..."
cp -a "$SOURCE_DIR" "$DEST_DIR"
if [ $? -ne 0 ]; then
echo "Error: Failed to copy directory."
exit 1
fi
# 查找可执行文件和库文件
echo "Stripping executable and library files in $DEST_DIR using $STRIP_PATH..."
find "$DEST_DIR" -type f \( -perm -u+x -o -name "*.so" -o -name "*.a" \) | while read -r file; do
if file "$file" | grep -q 'ELF'; then
echo "Stripping: $file"
"$STRIP_PATH" "$file"
if [ $? -ne 0 ]; then
echo "Warning: Failed to strip $file"
fi
fi
done
echo "Operation completed."
在build目录下，执行脚本../strip.sh dist ./dist_strip ~~/stm32/buildroot/output/host/arm-buildroot-linux-gnueabihf/bin/strip，~~/stm32/buildroot/output/需要替换为工具链位置，脚本会拷贝一份目标文件到dist_strip,并裁剪
[~/dev/everest/workspace/everest-core/build]$ ../strip.sh dist ./dist_strip ~/stm32/buildroot/output/host/arm-buildroot-linux-gnueabihf/bin/strip

未找到boost的filesystem和thread
原因：排查目录确实没有这两个库，查看buildroot →package→boost→config.in,
依赖depends on BR2_TOOLCHAIN_SUPPORTS_ALWAYS_LOCKFREE_ATOMIC_INTS导致menuconfig中无此选项
临时措施：屏蔽config.in中depend 勾选相应库，重新编译

-- Configuring incomplete, errors occurred!
临时在cross.cmake 增加设置SET(NODEJS_INCLUDE_DIR /usr/include/node)，发现cmake后make会报错unsafe

还是暂时使用x86的nodejs头文件拷贝至交叉编译头文件处
最后buildroot make clean后重新make，发现不再报_bz2的错误，而是报编译进程被杀死。将虚拟机内存从8G增加至12G编译通过。
cmake 出现报警交叉编译的依赖库路径被/usr/的目录隐藏，cmake成功后make 出现定义不完全。
cmake 有残留，删除build下的所有文件，重新cmake
报错：找不到Python.h
