Not sure if this works for the inclusion macros in the header files (#ifndef FILE_H #define FILE_H ... #endif). But perhaps it will give some hints? -- Alvin Back to top abecedarian@spambob.com Guest Posted: Fri Apr 29, 2005 3:01 pm    Post subject: Re: Static checker for C++ Alvin wrote: Quote: Chinmoy Mukherjee wrote: Hi Friends, I want to find out whether my C++ code(set of files) include some unused header files, do you know of any free static checker in linux for the job ?

Think about your proposal again I guess the fact that you have #ifndef FILE_H /uses/ the macro. -- Alvin Back to top Jay Nabonne Guest Posted: Fri Apr 29, 2005 4:09 pm    Post subject: Re: Static checker for C++ On Fri, 29 Apr 2005 14:41:46 +0530, Chinmoy Mukherjee wrote: Quote: Hi Friends, I want to find out whether my C++ code(set of files) include some unused header files, do you know of any free static checker in linux for the job ? Regards, Chinmoy How about grep? If the header file isn't being used, then it has not been #include'd anywhere. Simply search for the name of the header file in your source. The ones you don't find are not used. - Jay Back to top Victor Bazarov Guest Posted: Fri Apr 29, 2005 4:13 pm    Post subject: Re: Static checker for C++ Jay Nabonne wrote: Quote: On Fri, 29 Apr 2005 14:41:46 +0530, Chinmoy Mukherjee wrote: Hi Friends, I want to find out whether my C++ code(set of files) include some unused header files, do you know of any free static checker in linux for the job ?

Besides, including a header doesn't necessarily constitute "using". What if none of the constructs declared/defined in that header are ever used?

Well, grep -r :) Quote: Besides, including a header doesn't necessarily constitute "using". What if none of the constructs declared/defined in that header are ever used? Yep. How the OP meant "using" was a little unclear. Other answers went in the "nothing in the file is used" direction. I thought I'd throw that option out, just in case that happened to be what the OP meant. - Jay Back to top Carl Guest Posted: Fri Apr 29, 2005 4:34 pm    Post subject: Re: Static checker for C++ for every cpp file for every header include comment out the include compile the cpp file if( compile_errors ) un-comment out the header else remove header include from cpp this will work and its not that bad, because you can skip the header you know are required and consentrate on the others. I wonder if a compiler plugin could be run overnight to automate this process, if one could be built millions of compiling-hours a day could be saved by world-wide developers.

There is one caveat though: if a header file contains #defines that control compilation paths, the source file may compile *error-free* without the header file included, but it may compile *differently*. So the header file would still be needed to properly configure the compile. - Jay Back to top Display posts from previous: All Posts1 Day7 Days2 Weeks1 Month3 Months6 Months1 Year Oldest FirstNewest First         C++Talk.NET Forum Index -> C++ language (comp.lang.c++) All times are GMT Page 1 of 1   Jump to: Select a forum C/C++----------------C LanguageC Language (Moderated)C++ Language (Moderated)C++ language (comp.lang.c++)C++ language, library and standards Non-English C/C++ Newsgroups----------------C++ (German)C++ (French)  You cannot post new topics in this forum You cannot reply to topics in this forum You cannot edit your posts in this forum You cannot delete your posts in this forum You cannot vote in polls in this forum Powered by phpBB © 2001, 2006 phpBB Group SEO toolkit © 2004-2006 webmedic.
