cparser - A C99 parser (with GNU extensions)


cparser is a recursive descent C99 parser written in C99. It contains a preprocessor, lexer, parser, constructs an AST and does semantic analysis. It acts as a frontend to the libFirm intermediate representation library. This way optimization and code generation is performed. The compiler supports cross compilation to multiple target architectures with a command-line switch. It comes with driver logic for calling assemblers and linkers as well as parsing command-line options. This allows it to be a drop-in replacement for gcc or clang in many situations.

Building and Installation


  • A C99 compiler (gcc and icc are known to work).
  • libFirm-1.22

Building with make

Unpack libfirm in a directory called libfirm in the source directory alternatively you may setup an alternate location with a 'config.mak' file. Just type 'make' in the source directory. The results are put into a directory called "build". You can override the existing preprocessor, compiler and linker flags and built-in paths for include directories by creating a 'config.mak' file.

Building with cmake

cparser has an additional cmake build system. CMake is a complexer build system than the make based build and most cparser developers do not use it. However it can adapt the compiler and linker flags to build shared libraries for a wider range of systems, provides an installation target and is often more familiar for people preparing packages for distribution.

Notes for a cparser installation

While cparser often runs fine from the source/build directory, a proper installation should be configured with correct system paths. For this a config.mak file should be created and the following variables set apropriately for the system: PREFIX, SYSTEM_INCLUDE_DIR, LOCAL_INCLUDE_DIR, COMPILER_INCLUDE_DIR, MULTILIB_M32_TRIPLE, MULTILIB_M64_TRIPLE, variant=optimize. The variable may be defined empty; See config.default.mak and Makefile for details.
