Raspberry Pi - Elashell & Elatests not generated

[peter-strauss]

When cross-compiling the native Carrier for Raspberry Pi on Ubuntu, no executable elashell or elatests is created as for non-cross-compiled versions.

Activating ENABLE_APPS_DEFAULT or ENABLE_TESTS_DEFAULT in CMakeLists.txt file on root level starts the build process, but fails:
...
if(CMAKE_CROSSCOMPILING)
set(ENABLE_APPS_DEFAULT FALSE) #set to true
set(ENABLE_TESTS_DEFAULT FALSE) #set to true
else()
...

Additionally, from my understanding, Android and iOS versions also fall into the 'CMAKE_CROSSCOMPILING' category, therefore Raspberry versions will also have to be separated from the general cross-compiling code logic.

CMake build system in Carrier project doesn't support to build "apps" and "tests" directories for cross-compilation because of lacking dependency libraries, such as CUnit/libCurses, especially for Android/iOS platform. But you can try to make compilation for whole project on Raspberry platform, which will output elatests and all executable of apps.

@peter-strauss Can the cross-compilation for raspberry PI on Linux (Ubuntu or Debian) get successful result on your. environment , being exclusive of compilation for 'apps' and 'tests' directories? Those directories are not able to build when being cross-compilation, not only for raspberry pi, but for Android and iOS as well.

I checked it again for this on my ubuntu, and it still works. So, if the cross-compilation for raspberry PI on your environment works, please close this issue. Thanks :)
