I am trying to build a demo application using Kaa C SDK for esp8266. I am following official the programming guide. I am facing error while making the application (terminal screen shot is added).

I have tried changing the compile options as mentioned here Compiler options for esp8266. Also I have changed the linker file as mentioned in this post. Other notifications are gone and overflow is significantly reduced but it still it overflows by 4964 bytes while showing this error.

/opt/Espressif/crosstool-NG/builds/xtensa-lx106-elf/lib/gcc/xtensa-lx106-elf/4.8.2/../../../../xtensa-lx106-elf/bin/ld: kaa_demo section '.irom0.text' will not fit in region `irom0_0_seg'

/opt/Espressif/crosstool-NG/builds/xtensa-lx106-elf/lib/gcc/xtensa-lx106-elf/4.8.2/../../../../xtensa-lx106-elf/bin/ld: region `irom0_0_seg' overflowed by 4964 bytes

collect2: error: ld returned 1 exit status `make2: * [kaa_demo] Error 1 make1: * [CMakeFiles/kaa_demo.dir/all] Error 2 make: *** [all] Error 2

Please help.

In my case, I eliminated rest of the overflow by disabling some of the compile options. My compile options are 

cmake .. \

-DCMAKE_TOOLCHAIN_FILE=../kaa/toolchains/esp8266.cmake \
-DKAA_PLATFORM=esp8266 \
-DBUILD_TESTING=OFF \
-DCMAKE_BUILD_TYPE=MinSizeRel \
-DKAA_MAX_LOG_LEVEL=3 \
-DWITH_ENCRYPTION=OFF \
-DWITH_EXTENSION_NOTIFICATION=OFF \
-DWITH_EXTENSION_PROFILE=OFF \
-DWITH_EXTENSION_CONFIGURATION=OFF \
-DWITH_EXTENSION_EVENT=ON \
-DWITH_EXTENSION_LOGGING=OFF

Hope this helps.
