What you can do about it is to modify your last macro-defintion into following form: #define spec_namespace_unmanaged attribute ((namespace (". With gcc 8.3 I got the following build error: In file included from teamddbus.c:33: teamddbus.c: In function teamddbusinit: teamd.h:54:2: error. Spec_namespace_unmanaged int x → spec(section(".unmanaged")) int x Spec_namespace(unmanaged) int x → spec_namespace_unmanaged int x Preprocessor performs different actions on. So an invocation like this: FOO (bar) gets expanded to this: (params) replacement. that defines an object-like macro, where the symbol gets directly replaced by the replacement list, with no parameter substitution. It's clear that spec macro is evaluated twice, so no futher replacement is done, let's take it step-by-step: spec(namespace(unmanaged)) int x → spec_namespace(unmanaged) int x Macro is a piece of code or value that is replaced with the macro name before the execution of the program. When theres a space like this: define FOO (params) replacement. #define spec_namespace_unmanaged spec(section(".unmanaged")) #define spec_namespace(_H_) spec_namespace_#_H_ These nonreplaced macro name preprocessing tokens are no longer available for further replacement even if they are later(re)examined in contexts in which that macro name preprocessing token would otherwise have been replaced.įrom folowing macro-definitions: #define spec(_H_) spec_#_H_ This version also introduces a separate AI Assistant plugin specifically designed to help you with programming tasks. The Visual Expansion will enable you to visualize the preprocessor passes of the expansion. AugReSharper C++ 2023.2 is now available for download It brings support for several new C++20 and C++23 features, as well as Safe Delete refactoring to let you safely remove symbols from the source code. Furthermore, if any nested replacements encounter the name of the macro being replaced, it is not replaced. When you hover over a macro, you can access Quick Info, which now includes the Visualize Expansion link in addition to the Copy and Expand Inline options. As of Visual Studio 2017 version 15. The box at the top shows a statement taken from the. If the name of the macro being replaced is found during this scan of the replacement list (not including the rest of the source file’s preprocessing tokens), it is not replaced. Download scientific diagram 15: Expansion of a symbol defined as a macro and a C language element. Citing C99 draft 6.10.3.4 Rescanning and further replacement §2 (emphasis mine):
