1. Introduction

cparser is a recursive descent C99 parser written in C99. It contains lexer, parser, constructs an AST and does semantic analysis. It is currently used as a frontend to the libFirm intermediate representation, but can be used independently. cparser is able to bootstrap itself. It currently uses an external preprocessor.

2. Building and Installation

Requirements:

• A C99 compiler (gcc and icc are known to work).
• pkg-config (recommended)
• libFirm-1.21 or later

Make sure you have installed libFirm and pkg-config can find the libfirm.pc files ("pkg-config --modversion libfirm" should work). Use (GNU)-make to build cparser.

3. Troubleshooting

x86_64 Systems: libFirm uses a 32bit x86 backend by default, while it also uses the systems default preprocessor/linker. This results on a x86_64 linker being used for 32bit assembly. If you see assembler errors like "suffix or operand invalid for 'push'", then you probably have this problem. Use the -m32 flag to force usage of system 32bit preprocessor/linker.
