I want to cross compile amazon Alexa SDK in openwrt platform, but it can not find curl/curl.h when excute make, Here is my operate step:

  1. create a cmake toolchain file like this:

    SET(CMAKE_SYSTEM_NAME Linux)
SET(CMAKE_SYSTEM_VERSION 1)
SET(CMAKE_C_COMPILER  arm-openwrt-linux-muslgnueabi-gcc)
SET(CMAKE_CXX_COMPILER  arm-openwrt-linux-muslgnueabi-g++)

SET(CMAKE_FIND_ROOT_PATH  /home/sundq/workspace/Develop/out/astar-parrot/staging_dir/target/rootfs)

SET(CMAKE_SYSROOT  /home/sundq/workspace/Develop/out/astar-parrot/staging_dir/target/rootfs)

SET(CMAKE_LIBRARY_PATH  /home/sundq/workspace/Develop/out/astar-parrot/staging_dir/target/rootfs/usr/lib)

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(CMAKE_C_FLAGS "-I/home/sundq/workspace/Develop/out/astar-parrot/staging_dir/target/rootfs/usr/include")

SET(CMAKE_CXX_FLAGS "-I/home/sundq/workspace/Develop/out/astar-parrot/staging_dir/target/rootfs/usr/include")

  2. excute cmake like this:

    cmake ../avs-device-sdk-master-v1.0.2/ -DCMAKE_BUILD_TYPE=MINSIZEREL -DCMAKE_TOOLCHAIN_FILE=../toolchain.cmake

  3. excute make, the output is:

    /AVSCommon/AVS/src/AlexaClientSDKInit.cpp:18:23: fatal error: curl/curl.h: No such file or directory

I'm sure the curl/curl.h file exist in /home/sundq/workspace/Develop/out/astar-parrot/staging_dir/target/rootfs/usr/include directory.

  • In short: you need to set **cached** variables *CMAKE_C_FLAGS* and *CMAKE_CXX_FLAGS*. – Tsyvarev Sep 21 '17 at 08:03

The proper way is to create an OpenWrt package for Alexa and add libcurl as a dependency.

Check here in how to create a package.
