1. The generator handles just the COMPILE_DEFINITIONS.
(See: __ZEPHYR_SUPERVISOR__)
For the defines in INTERFACE_COMPILE_DEFINITIONS
a special handling is necessary.
Solution:
The amendment function generates a macro header file
${CMAKE_BINARY_DIR}/zephyr/include/generated/cmake_intdef.h
based on INTERFACE_COMPILE_DEFINITIONS and appends the
defines from the file to
CMAKE_EXTRA_GENERATOR_C_SYSTEM_DEFINED_MACROS.
2. Eclipse CDT4 indexer has problems with CMake 'Eclipse CDT4 - x'
generator projects that use mixed C/C++.
The Eclipse CDT4 indexer is showing a lot of unresolved symbol
errors, when the project was created with CMake generator and
the code is a mix of C and C++.
The root cause of the problem is the g++ built-in __cplusplus macro,
that is passed by CMake generator in the '.cproject' file.
The defines in '.cproject' are always the same for C and C++.
In mixed C/C++ projects, the header files often contain the following
lines to let C++ code call the C functions:
#ifdef __cplusplus
extern "C" {
#endif
< header content >
#ifdef __cplusplus
}
#endif
Whenever the Eclipse CDT4 indexer compiles the code for
code analysis, it has the macro __cplusplus set,
independent of whether standard C or C++ source files are compiled.
The 'extern "C"' confuses the standard C compilation and the indexer
is messed up.
Solution:
The amendment function deletes the __cplusplus entry from
CMAKE_EXTRA_GENERATOR_CXX_SYSTEM_DEFINED_MACROS.
3. The amendment function appends the defines from
${CMAKE_BINARY_DIR}/zephyr/include/generated/autoconf.h to
CMAKE_EXTRA_GENERATOR_C_SYSTEM_DEFINED_MACROS.
