I'm a newbie in both LLVM developing and cpp.
I wanted to ask if there was a way to develop a pass for LLVM in Xcode having all the typical features available in an IDE like autocomplete and syntax code highlighting.
Right now I am just writing c++ code, checking everything I need on the documentation, but, as you can imagine, this is really slowing me down and it's really error prone...
Don't know if this can help, but my LLVM folder is structured this way:
"llvm_3.8_source/" root folder of llvm3.8 source files
"llvm_3.8_source/build" root folder of my llvm3.8 build
Thanks
Yes, it is possible.
LLVM uses CMake as a build-system generator. CMake supports such things as old good makefiles, ninja, xcode, and visual studio.
You can simply create Xcode-project using the following commands from terminal:
cd llvm_build
cmake -G Xcode path/to/llvm/sources
open LLVM.xcodeproj
First you will see lots of errors and 'red' marks. It's because some parts of LLVM sources are generated during compilation.
All files will be generated as soon as you attempt to build project first time and all the 'red' marks will gone.
You can read this article to get a bit more info on the topic:

I want to build a C++ code but it errors. When I check the error message it's related with .NET. I have C# extensions but this isn't C# and I want to change this to g++ for C++ projects. I have g++ installed and added to path however I don't know how can I configure it to build with that for C++ codes.
Edit: I marked the answer as a solution but I also found an easier way for me:
https://code.visualstudio.com/docs/cpp/config-msvc
cl.exe basically.
One option (probably not the one you want to) is to build it from integrated terminal.
You can download c/c++ extension along with the cmake tools extension to have buttons for build/run configuration.
I've been trying to research this for a while and my limited experience with compiling is hindering my ability to figure it out.
Basically, I have some code which is being written in Qt Creator, then built with these build steps:
qmake.exe [project name].pro -spec win32-msvc "CONFIG+=qtquickcompiler"
jom.exe in C:\eclipseworkspace\[project directory]
I'd like to use the Fortify SCA (Static Code Analyzer) to automatically scan this code for vulnerabilities, but most of its user-friendly features are designed towards Java. I haven't given up, though, because Fortify does claim to be able to scan C++ code that uses 3rd Party Compilers (which I assume Qt falls into that category).
(Page 37 of this document)
As a preliminary step to running Qt Creator on my actual code, I've wanted to see if I can at least get it to run on any Qt sample project, to see what the steps to do that would be.
I'm using Qt 5.12.7
on a Windows 10 OS
with the MSVC2017 32bit compiler,
but I feel any correlation between Qt and Fortify that works will be enough to set me off in the right direction.
Or perhaps my optimism is misplaced and I just don't understand the limitations of what I want to do. Either way, it'd be nice to know.
I have found this to be easiest on Linux. I think this solution translates to Windows.
You must inject the sourceanalyzer into your compiler command.
For example, I run cmake to configure my projects.
export CC="sourceanalyzer -b <your_project_name_here> gcc"
export CXX="sourceanalyzer -b <your_project_name_here> g++"
cmake <bunch of my cmake definitions> <path_to_src>
# I do a clean to remove what sourceanalyzer picks up during configuration time tests.
sourceanalyzer -b <your_project_name_here> -clean
sourceanalyzer -b <your_project_name_here> -scan -f scanResults.fpr
I have a C++ Xcode project on Mac, and I'd like to see how much code coverage my tests have. If I were building on linux, I would pass a few extra flags to GCC and then use gcov.
What I'm looking for is a way to do something similar on Mac, either through Xcode or through the command line.
This link describes how to get the code coverage tools that Xcode has built in to work, but unfortunately those seem to only work for ObjC or Swift. All the other articles I've found have been similarly unhelpful (either very out of date or only for Swift/ObjC).
I'm not sure how to get this running through the command line, since I'm not even sure what command(s) Xcode uses to build my project (I assume xcodebuild, but I'm not sure what arguments).
I'm fine with doing this either through the command line or through Xcode, whichever is easier.
Any help would be appreciated, please let me know if you need any more details.
Details:
I am using Xcode Version 10.1 (10B61).
I'm trying to start a work in vscode , latest C++ plugin version supports ms debugger, so as I'm mostly working under windows it was a signal to try this.
c++ tools plugin from MS and cmake tools were installed.
my test project was however not built . the problem is clear , but I need an advice from experienced vscode users how to solve this right.
cmake doesn't see vc compiler.
(after using QtCreator) I expected that vscode could detect vc installation... however that's not so. ok, I have a two ways:
fill environment variables INCLUDE/LIB/PATH with a headers, libs and binaries
just run vcvarsall.bat x64
Second way is a simple and reliable. so final question is:
how to run .bat at the begining of vscode start?
(I don't mean write another bat/cmd, prepare the environment and run vscode inside the same script after that)
Although the question is fairly old, I'll try to give a useful answer, in case others stumble across, just like I did.
I believe what you are trying to achieve is not possible. Code inherits the environment it was started with. If you did not launch it from a developer command prompt, you will not be able build and debug. (Building might be possible if every task first starts the vcvarsall.bat, but that slows things down by a lot. Debugging I think will still not work.)
If you are willing to, you can check out vector-of-bools CMake Tools extension which does build automation as well as automatic MSVC detection. It builds using CMake (thus you need to write your build scripts using CMake), but it will take care of building just by pressing F7, like what most VS users are familiar with.
I was wondering whether it's possible to use Microsoft's C++ compiler and linker with NetBeans IDE?
If so, what's the best way of doing it.
P.S. I'm not interested in Mingw.
EDIT: Is it possible to get NetBeans to do error parsing (so that I can click on error and have NetBeans open the right file), intellisense, etc? I know NetBeans can work with g++ make files. Why not with nmake?
I am currently writing a plugin/toolchain to use Visual C++ on Netbeans.
You can find the project called VCC4N on source forge or on NetBeans plugins.
To be honest, I always do my spare time coding inside an ide (e.g. code::blocks, monodevelop, anjuta) or an editor (virtually always scite), and the compiling I do in a terminal via a makefile (handwritten, cmake, automake).
This isn't really a problem w.r.t. time to compile: F7 (or some other of the F keys) vs. (alt+tab, up, enter), where (alt+tab) and (up) are pressed nearly at the same time, but I get the great benefit of having up to full screen compiler reports, and often I am anyways testing my programs in a terminal. Also, it makes my code more independent of the IDE (ever tried to get a makefile from code::blocks for distribution purposes?).
The visual studio compiler is called cl.exe and the linker is link.exe. These are present in particular visual studio directories. From inside visual studio > project properties > C++ > Command Line, or by disabling "Suppress Banner" option there, you can find the command that visual studio runs. You can call these command lines from inside netbeans.
Getting all the file names into the list to compile may be more tricky. You need a build system for this. You can try to use the same mechanism that visual studio uses, but sorry my knowledge fails there. Alternatively, you can use CMake or some other build system. Then, whenever you add/delete a source file, you would have to update the CMakelist.txt to be able to compile.
You can get syntax highlighting, code graphing etc from netbeans without having a compiler installed I think (not certain, you may need cygwin or mingw for parsing). What you must do is create at least an empty makefile. If you want to use Microsoft's compiler then you either need to:
a) Write the makefile yourself to compile eveything using cl
b) Call on msdev from the makefile with the project name and it will compile everything
b) Call something like scons from the makefile to compile everything
I use netbeans to develop cross platform software, at this time though, I don't actually run the builds from netbeans.
