# cmake: Eclipse CDT4 generator amendment
|
|
#
|
|
#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.
|
|
