Kaaproject esp8266构建冲突类型

Question

我已经安装了ESP8266 SDK与工具链，并尝试构建由kaa生成的项目CDataCollectionDemo。我就会犯这样的错误

/opt/Espressif/esp-rtos-sdk/include/espressif/c_types.h:47:29: error: conflicting types for ‘size_t’
 typedef unsigned int        size_t;
                             ^
In file included from /opt/Espressif/esp-rtos-sdk/extra_include/string.h:14:0,
                 from /home/tung/kaa/project/CDataCollectionDemo/targets/esp8266/target.

这是完整的输出

我所做的一切都遵循kaa文档，除了将-DKAA_PLATFORM=esp8266参数添加到build.sh文件中的cmake命令之外。你能告诉我这里有什么问题以及如何解决吗？谢谢!

更新

我在cmake命令中添加了一些参数，就像@MrKoin建议的那样，但仍然会出现错误

Cmake论点

cmake .. \
        -DCMAKE_TOOLCHAIN_FILE=../libs/kaa/toolchains/esp8266.cmake \
        -DKAA_PLATFORM=esp8266 \
        -DCMAKE_BUILD_TYPE=MinSizeRel \

输出

好像有些图书馆不见了。我现在该怎么做？谢谢!

Answer 1

看起来您需要在cmake参数中指定cmake工具链文件：

cmake -DCMAKE_TOOLCHAIN_FILE=../libs/kaa/toolchains/esp8266.cmake \
    -DKAA_PLATFORM=esp8266 .. 

详情请参阅文档。

Answer 2

这可能与您从Kaa网站引用的教程中的步骤5安装ESP8266 RTOS有关。

您运行了命令sed -i 's:#include "c_types.h"://#include "c_types.h":' $ESP_SDK_HOME/include/lwip/arch/cc.h吗

我记得我遇到了类似的(或相同的)问题，忘记执行这个命令。它注释掉与其他地方的类型声明相冲突的#include。

Answer 3

您需要编辑build.sh文件，查找build()并更改代码：

build() {
    mkdir -p "$PROJECT_HOME/build"
    cd "$PROJECT_HOME/build"
    cmake ..\
    -DKAA_TARGET=esp8266\
    -DCMAKE_TOOLCHAIN_FILE=../libs/kaa/toolchains/esp8266.cmake \
    -DBUILD_TESTING=OFF \
    -DKAA_PLATFORM=esp8266 \
    -DBUILD_TESTING=OFF \
    -DCMAKE_BUILD_TYPE=MinSizeRel 
    make
}
