У меня ошибка предварительной обработки для компиляции проекта gtest с заголовками tizen на ci-runners gitlab (Debian GNU / Linux 10 (buster)). gcc (Debian 8.3.0-6) 8.3.0

Но на локальном компьютере Ubuntu 16.04 успешно компилирует это. gcc (Ubuntu 5.4.0-6ubuntu1~ 16.04.11) 5.4.0 20160609

У меня установлен Tizen Studion 4.1 с SDK: WEARABLE-5.5 и knox_add_on_sdk_2.5.0. Экспортированный ПУТЬ env в tools / ide /bin и package-manager, а также tizen_include_root

Чтобы воспроизвести проблему, вы должны использовать #include <tizen.h> в проекте, который используется gtest и абсолютный путь к заголовкам tizen в include_directories(…

 cmake_minimum_required(VERSION 3.5)
project(tests)

Как я могу разделить заголовки tizen и system и какие заголовки я должен использовать?

Проблема решена. Используя прямой путь к компилятору в CMakeList.txt помог мне.

 if(DEFINED ENV{TIZEN_SDK_HOME})
    set(CMAKE_CXX_COMPILER $ENV{TIZEN_SDK_HOME}/tools/i586-linux-gnueabi-gcc-6.2/bin/i586-linux-gnueabi-g  )
 

Вы должны использовать ФЛАГИ с —sysroot и -L для библиотек tizen

 SET(gcc_root "$ENV{TIZEN_SDK_HOME}/platforms/tizen-5.5/wearable/rootstraps/wearable-5.5-emulator.core")

set(CMAKE_C_FLAGS "--std=c99 ${CMAKE_C_FLAGS}")
set(CMAKE_C_STANDARD 99)
set (CMAKE_CXX_FLAGS "--std=c  14 --sysroot=${gcc_root} -L${gcc_root}/lib -L${gcc_root}/usr/lib ${CMAKE_CXX_FLAGS}")
 

Также необходим LDFLAGS

 export gcc_root=${TIZEN_SDK_HOME}/platforms/tizen-5.5/wearable/rootstraps/wearable-5.5-emulator.core
export LDFLAGS="--sysroot=${gcc_root} -L${gcc_root}/lib -L${gcc_root}/usr/lib"
