I have clang 11.0.0 installed on Windows 7. I used clang++ to compile a simple helloworld.cpp and no problem: clang++ helloworld.cpp -c Now my goal is to target WebAssembly, so I ran: clang++ helloworld.cpp –target=wasm32 -c This gave me error "iostream file not found". I used verbose to see that the include path had: ignoring ..
From Clang’s documentation: When Clang compiles C++ code for Windows, it attempts to be compatible with MSVC. In particular, Clang defines _MSC_VER. MSVC does not support #pragma STDC FENV_ACCESS ON: cl t125.c /std:c11 t125.c(11): warning C4068: unknown pragma ‘STDC’ Instead MSVC does support #pragma fenv_access (on). This leads to this code: #if _MSC_VER #pragma fenv_access ..
I am trying to execute a .cpp file with the following content: #include "clang/Tooling/CommonOptionsParser.h" #include "clang/Tooling/Tooling.h" Whenever I try to, I get the following error: fatal error: ‘clang/Tooling/CommonOptionsParser.h’ file not found #include "clang/Tooling/CommonOptionsParser.h" ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 1 error generated. I already found this question and tried what was recommended but there is no change. For reference, I ..
I have a clang-format based off of LLVM but I found it surprisingly hard to find a setting to add space after comment start. Basically, I’d like to have: // This is a comment instead of: //This is a comment Here’s the .clang-format I’m using at the moment: # Generated from CLion C/C++ Code Style ..
When I was reading about using shared libraries, I learnt how the definitions of standard C functions, like printf, are resolved during run-time. I want to implement functions in my project in the similar manner. I can have stub definition of functions for compiling and linking phase. And actual definition of the functions will be ..
I have recently switched to ubuntu (20.04.2 LTS) and have tried installing clang (and clang++). I did it with: sudo apt-get install clang and can find clang and clang++ in /usr/bin When I try to compile any program, I get a "segmentation fault". (I did compile a simple program that prints "hello" with g++ and ..
I have a MacBook M1 and have installed a library on my machine that was compiled for an x86 / Intel architecture. I have some source code that uses OpenMP. I would like to compile my code and link my executable to the x86 library using a clang compiler. I am able compile source code ..
opt command not working for CLANG compiler, installed CLANG and LLVM, after I ran clang++ -emit-llvm -S test.cpp -o prog.ll it is working well and good but once I tried running the ‘opt’ opt –dot-cfg prog.ll I am getting the error as ‘opt’ is not recognized as an internal or external command, operable program or ..
How should I include standard and not-standard libraries in c++ programms for clang on freeBSD? With standard I mean things like <iostream> with non-standard I mean things like /usr/local/include/opencv4/opencv2/core.hpp. I am lost on my path in freebsd 13.0. So far I used cc (clang) to compile c programs. To include port libraries I use cc ..
Say we have a big codebase and a function string blockRead() that performs some blocking IO. I was hoping to change this function into a coroutine my_task<string> coroRead() and use clang to automatically refactor the entire codebase to use the co_await coroRead() instead of blockRead(). Of course the hard and tedious part is traversing the ..
