海外TECH	DEV Community	Compiling C/C++ on both Windows and Linux, with address sanitizer!	https://dev.to/midnqp/compiling-cc-on-both-windows-and-linux-with-address-sanitizer-3ikn	Compiling C C on both Windows and Linux with address sanitizer This article was put together from my findings when I tried to compile libcpy for Windows Please enjoy Let s say we have some C C code already written for gcc in linux We want to compile them for Windows as well To have greater portability How can we achieve this Which toolchain to select What are the obstacles In this article we ll explore Les problèmesHow everything other than VS fails In CMake for VS Code you can have some preset CMake configurations in CMakeSettings json file Also known as toolchain or kits for clang mingw cl etc However mingw doesn t have address sanitizers clang throws syntax errors for multi line macro same as cl cl doesn t fully support C so unsigned stack va arg count is an error because it expected a constant expression of intall of the may not be portable in visual studio if you just clone libcpy from github and open that folder in VS then VS just sells you the support VS has for CMake providing absolutely no support at all for any compiler include dir lib dir linking address santizer or toolchain in VS code you may have quite a hard time in larger projects e g linking external shared libraries i e vld x with the compiled executable using CMake La lumière de la solutionEnter Microsoft Visual Studio The pinnacle of excellency from Microsoft An under appreciated humble big friendly giant A champ A software specimen If you ask any airline is this flight safe they reply something to the effect of oh your trip to the airport was the most risky part If you ask me how does it feel coding in VS I d brighten up my charm and uplift my morale to say double clicking this app was the hardest part T is liketh wat r L appréciationSo a major reason behind migrating to Microsoft VS was to have great support great tooling and ease in development VS has a ton of features tooling extensions options configurations So much so that in the beginning it may feel like an overkill or a bloat However each feature has a purpose of life and each of them are helpful Each of them are built over years of demand from low level developers from around the global over more than a decade of feedback La confusion Let s say I have a Project for dll in C C in a Solution In the same solution I have another Console App Project to use the library You turn on Enable Address Sanitizer from Project Properties on the console app and the whole app crashes for some people Apparently Visual Studio developers tried fixing this flaw However this is not fixed yet The error output will almost spam your debug console with the following message in enormous quantity Exception thrown at xFFBBF KernelBase dll inmain exe xC Access violation writing location xFFCCE Please do note that this major problem is for x only However a dev from the Visual Studio team said that the silent violations are normal and not a bug This is incorrect because these silent normal access violations cause all memory leaks to be undetected when compiled with Visual Studio s lovely library to detect memory leaks lt crtdbg h gt which we ll discuss later causes deadlier more messy unfixable Stack overflow errors when compiled with Visual Leak Detector lt vld h gt crashes the application immediately for some people La good news DJust don t turn on Enable Address Sanitizer for the console app That s it That s how all of the problems in the previous section can be completely mitigated Les armes ️There are quite a number of libraries and tools to detect memory leaks but the following two worked great for me Both of the library masterpieces work without enabling fsantize address hence no access violation errors Let s say we have a piece of code and let s see how they turn out include lt crtdbg h gt This is a system library from the C Runtime library of Microsoft Visual Studio Therefore this library is available is no other platform except Windows The library works exceptionally well and it automatically binds itself to all app exit points and outputs memory leak info Let s say the code we have is define CRT SECURE NO WARNINGS define CRTDBG MAP ALLOC include lt stdlib h gt include lt crtdbg h gt int main CrtSetDbgFlag CRTDBG ALLOC MEM DF CRTDBG LEAK CHECK DF char str malloc strcpy str hello free str return The corresponding output Detected memory leaks Dumping objects gt main c normal block at xCFB bytes long Data lt hello gt some hex values Object dump complete include lt vld h gt This library is developed by KindDragon Another acme of human intelligence However the fork from Azure seems to fix an issue Let s say the code we have is include lt stdlib h gt int main char str malloc strcpy str hello free str return The corresponding output WARNING Visual Leak Detector detected memory leaks Block at xCCD bytes Leak Hash xCCADD Count Total bytesCall Stack TID ucrtbased dll malloc more call stack more call stack C Users USER main c more call stack more call stack Data The readable value of the pointer hello outputs the surrounding heap outputs the surrounding heap La final thoughtsMsys may help while coding in Visual Studio And as we discussed you may get VS code to work correctly on a large project however Microsoft Visual Studio would be the best practice Apparantly you can code for Linux from VS however gcc and gdb has complete support for address sanitizers	2022-11-20 04:04:30
