Preprocessor Include Paths, Macros

The C/C++/CUDA editors use the CDT indexer to improve syntax highlighting, allowing you to jump to macro definitions and to browse through include files.

The following table lists the compiler executables supported by the JSON Compilation Database Parser.

Compiler	Vendor/Standard	Language	Macros	Include directories	System include directories	Macros file	Include file	Compiler executables
gcc	GNU Project	C	Yes	Yes	Yes	Yes (-imacros)	Yes (-include)	cc, cc.exe, gcc, gcc.exe, ".+-gcc", ".+-gcc.exe"
g++	GNU Project	C++	Yes	Yes	Yes	Yes (-imacros)	Yes (-include)	c++, c++.exe, g++, g++.exe, ".+-g\+\+", ".+-g\+\+.exe" , ".+-c\+\+", ".+-c\+\+.exe"
clang	LLVM Project	C	Yes	Yes	Yes	N/A	Yes (-include)	clang, clang.exe
clang++	LLVM Project	C++	Yes	Yes	Yes	N/A	Yes (-include)	clang++, clang++.exe
cc	POSIX	C	Yes	Yes	No	No	No	cc, cc.exe
c++	POSIX	C++	Yes	Yes	No	No	No	c++, c++.exe

Remarks:

".+-gcc" This representes a Java regular expression that also matches a target triplet, thus allowing to work with cross-compilers named like e.g. arm-none-eabi-gcc.
".+-g\+\+" This representes a Java regular expression that also matches a target triplet, thus allowing to work with cross-compilers named like e.g. arm-none-eabi-g++.

Compilers supported through separate plug-ins

JSON Compilation Database Parser Compiler Built-ins detection

This feature also tries to get the include paths and preprocessor macros built-in to the compiler.
Note that this works only for compilers that supporting it. See built-ins detection for supported compilers.
