Kaaproject esp8266 build conflicting types - kaa

Question

I have installed the ESP8266 SDK and toolchain and try to build the project CDataCollectionDemo which is generated from kaa sandbox. And I get the error like this
/opt/Espressif/esp-rtos-sdk/include/espressif/c_types.h:47:29: error: conflicting types for ‘size_t’
typedef unsigned int size_t;

Everything I did follow the kaa documentation, except adding the -DKAA_PLATFORM=esp8266 argument to cmake command in build.sh file. Can you tell me what's problem here and how to fix it. Thank you!
Update
I have added some arguments to cmake command as #MrKoin suggested but still get an error
Cmake arguments
cmake .. \
-DCMAKE_TOOLCHAIN_FILE=../libs/kaa/toolchains/esp8266.cmake \
-DKAA_PLATFORM=esp8266 \
-DCMAKE_BUILD_TYPE=MinSizeRel \

It seems like some libraries missing. What should I do now? Thanks!

Answer 1

Looks like you need to specify cmake toolchain file in cmake arguments:
cmake -DCMAKE_TOOLCHAIN_FILE=../libs/kaa/toolchains/esp8266.cmake \
-DKAA_PLATFORM=esp8266 ..
Please, refer documentation for details.

Answer 2

It might be related to step 5 Install ESP8266 RTOS SDK in the tutorial you referenced from the Kaa website.
Did you run the command sed -i 's:#include "c_types.h"://#include "c_types.h":' $ESP_SDK_HOME/include/lwip/arch/cc.h?
I remember I had a similar (or the same) problem and forgot to execute this command. It comments out an #include which conflicts with the declaration of types elsewhere.

Answer 3

You need to edit the build.sh file,
find build() and change the code:
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
}
