一、交叉编译openssl

二、交叉编译curl

三、修改CMakeLists.txt

set(CMAKE_HOST_UNIX true)
set(CURL_INCLUDE_DIR /opt/huishi-rv1106/thirdpty/libcurl/include)
set(CURL_LIBRARY /opt/huishi-rv1106/thirdpty/libcurl/lib)
set(OPENSSL_INCLUDE_DIR /opt/huishi-rv1106/thirdpty/openssl/include)
set(OPENSSL_CRYPTO_LIBRARY /opt/huishi-rv1106/thirdpty/openssl/lib)
set(OPENSSL_SSL_LIBRARY /opt/huishi-rv1106/thirdpty/openssl/lib)

然后设置编译选项

四、修改sdk文件夹中的CMakeLists.txt

主要是编译时提示找不到openssl目录，故添加

target_include_directories(${PROJECT_NAME}${STATIC_LIB_SUFFIX}
    PRIVATE "/opt/huishi-rv1106/thirdpty/openssl/include")

 

五、编译

cmake \
-DCMAKE_AR=/opt/env_toolchain_0331/env/arm-rockchip830-linux-uclibcgnueabihf/bin/arm-rockchip830-linux-uclibcgnueabihf-ar \
-DCMAKE_CXX_COMPILER=/opt/env_toolchain_0331/env/arm-rockchip830-linux-uclibcgnueabihf/bin/arm-rockchip830-linux-uclibcgnueabihf-g++ \
-DCMAKE_C_COMPILER=/opt/env_toolchain_0331/env/arm-rockchip830-linux-uclibcgnueabihf/bin/arm-rockchip830-linux-uclibcgnueabihf-gcc \
..

六、输入指令make 

说明：

错误：Error running link command: No such file or directory

解决办法：增加set(CMAKE_AR  $(TOOLS_DIR)/build/1.7/sysroots/x86_64-pokysdk-linux/usr/bin/arm-poky-linux-gnueabi/arm-poky-linux-gnueabi-ar CACHE FILEPATH "Archiver")。因在cmake 时指定了交叉编译器路径，故在外面指定CMAKE_AR

原因：查看编译的中间文件link.txt，发现是链接静态库的ar工具未设置成功（CMAKE_AR-NOTFOUND）
