QA-MISRA Preprocessor Configuration

This technical note shows how to configure the preprocessor for the QA-MISRA static analysis tool. It aims to help users transition from their compilation setup to the QA-MISRA analysis tool.

• It provides instructions on how to get the necessary compiler-specific information like predefined macros and include search paths to set up QA-MISRA. This is needed because QA-MISRA uses the Clang preprocessor, but users likely compile with a different compiler.
• It explains how to use compiler options like -dM and -E in GCC/Clang to output preprocessor definitions and include paths.
• The configuration needs to be done separately for C and C++ languages.
• Project/file specific preprocessor settings like macros and include paths can be added manually or imported from a JSON compilation database.
• It mentions the QA-MISRA documentation and option for a free web session on setting up the first project.
