I use VSCode(code editor, not IDE) for C++ with only Microsoft's C++ extension and today I have encountered a problem here. When I write the wrong syntax, the "PROBLEMS" panel does not show errors. It only shows errors on building the code. Earlier that wasn't the case. How do I fix this ?
Before building:
After building:
I got that error by Disable error squiggles. If you don't reach that error in my case, don't read anymore.
After ignoring, I got your problem:
To fix this, open settings.json file:
Scroll to the end, then set "C_Cpp.errorSquiggles": from Disabled to Enabled.
After reading the question, and the comments, my understanding is that you want Visual Studio Code to tell you when you make a mistake on the sintax, without having to compile the project.
What could be wrong is your C++ IntelliSense, which is odd because it comes in bundle with the C/C++ extension from Microsoft. The extension itself might be disabled, corrupted during an aborted update, or uninstalled.
Have you tried the good old and helpful uninstall and reinstall the extension? That normally fixes my problems with extensions in Visual Studio and VS Code
Note: You have to install the extension first: C/C++ IntelliSense, debugging, and code browsing extension
This is because the C/C++ IntelliSense, debugging, and code browsing extension does not know about the current project.
Navigate to View | Command Palette, enter and select C/C++ Build and debug active file: Select
Project, and then select the correct project that you want to work with.
This will help you see the problems as you create your code without requiring you to run it.
The extension has to know that it is allowed to continuously check your code.
I hope this helps you in the future with other extensions too...
Try and close your current folder and open a different folder. Then come back to your original folder. This worked for me.
I installed Visual Studio Code 1.1 with the C/C++ extension,
opened my C++ project and tried to use "Go to definition" in vain.
The "Go to definition" is not working at all.
Example, go to definition of a class member:
int i = m_myVar;
(I opened a simpler project with one file and it was working for this one)
In the end, what I want is good indexation of my big project, is there a way to install Intellisense?
I had a the same issue: F12 and Ctrl + Click and Right Click "Go To Definition" wasn't working.
The fix for me was:
Go to Extensions
Click "Disable All Installed Extensions"
Close and Reopen VS Code
Back to Extensions and "Enable All Extensions"
Essentially enable/disable all extensions fixed the issue.
I recently came across this same issue and after trying all of the suggested solutions I could find with no success, I found this article:
https://code.visualstudio.com/docs/setup/linux#_visual-studio-code-is-unable-to-watch-for-file-changes-in-this-large-workspace-error-enospc
Basically my project grew too large and VS code was no longer able to track all files, which messed up the "go to definition" functionality.
After following the steps on the link to increase the maximum number of files to be tracked, the issue was resolved.
The correction is pretty simple (tested on Ubuntu 18.04):
Add this line:
fs.inotify.max_user_watches=524288
to the end of the file /etc/sysctl.conf
After saving, run the following command:
sudo sysctl -p
Hopefully this will be useful to someone else, this has been bothering me for the last few days.
I had a similar problem except with Python and google searches for solutions kept bringing me back to this post so I figured I'd post my solution here in the hopes that it might help other people.
I was working on a remote cluster through VScode Remote and was getting similar errors to the original question(all 'go to ___' functionality was unavailable and was even getting a 'too large to track' error) and I thought I had to increase the number of watches, which didn't end up helping.
All I needed to do was install a python interpreter on the remote VScode server. This fixed my problem.
I believe vscode 1.1 (well, 1.1.1 actually) + the C++ extension (cpptools) is as much Intellisense as we can get for now.
You should load your big project with the "open folder" function to make vscode know about the other files.
https://blogs.msdn.microsoft.com/vcblog/2016/03/31/cc-extension-for-visual-studio-code/ warns about letting the indexing finish first (red icon in lower right corner during indexing) and mentions the current limitations on the source code parsing.
It wasn't working on my laptop as well after installing a few VSCode extensions. I decided to close and re-open VSCode with administrator permission and suddenly it sorted out.
I have been trying to fix this for a long time. In the end, what worked for me was simply reinstalling VSCode, then installing the latest C/C++ extension (v0.18.1). Then, in your .vscode/c_cpp_properties.json file, under includePath, add your include folder which has all your header files.
I tried the methods mentioned in this thread none of them seemed to work for me. A simple solution that worked for me is that I closed the current workspace and created a new workspace, added the folders which I required(same as the old workspace), and saved the new workspace. Waited for a couple of minutes to index and IntelliSense is able to find definitions now.
I am using VSCode 1.52.1 on Ubuntu 20.04.
In my case, for whatever reason,c_cpp_properties.json has become set to Disabled in ~/.config/Code/User/settings.json.
Manually changing it to Enabled solved the problem.
Fixed mine by UNCHECKING C_Cpp > Default > Limit Symbols To Included Headers
Your mileage may vary. Good luck!
Have you saved your workspace? Or did you just open a folder with File->Open Folder? This question already has many answers, but none of them address this case, which was my issue.
The question is not specific enough for me to know if you are having the exact same symptoms as my case.
If:
You have not saved your workspace. vscode doesn't say "(workspace)" at the top of the window.
None of the goto functions are working, but instead report: "No ___ found for ____"
The tag parser database icon in the bottom right is always there but only reports "Parsing open files", rather than telling you how many files have been parsed.
Then:
Try saving your workspace.
If you have multiple versions of a language on your PC, specify the exact language you are using in the VScode(in my case, I am using Python, so I must specify the version to the python Interpreter in VS Code)
If you could not do it whatsoever, then uninstall all the other versions that you don't use and then if you go to VS Code, it will ask the version to be used, and you would have only one version, so when you select the version, the "Go To Definition" will be activated.
I was having a similar issue with java on Ubuntu 20.04 using OpenJDK version 11 (openjdk-11-jdk in apt). At first I didn't have the JRE installed, so I installed it and it still didn't work.
Afterwards, I went to the CTRL + SHIFT + P menu and then to Java: Configure Java Runtime, there I saw in the Java Tooling Runtime tab that /usr/lib/jvm/java-11-openjdk-amd64 was selected, changed it to /usr/lib/jvm/java-1.11.0-openjdk-amd64 just to see if it would work, and after a restart it did. I'm not sure why this is, but I hope it may help somone else.
For python ensure your code analysis settings are correct. In my case the languageServer was accidentally set to 'None'. Reverting it to 'default' or 'pylance' did the trick.
Just to inform if none of above works then
In my case i was using Kite extension in my VS code, I just disabled it and it worked. I think kite extension is blocking this feature.
OS: Linux Ubuntu 22.04
if you encountered with following error:
"The .NET Core SDK cannot be located. .NET Core debugging will not be enabled. Make sure the .NET Core SDK is installed and is on the path."
Normally Vscode remains unable to locate .Net sdk. need to set path manually.
sudo ln -s /snap/dotnet-sdk/current/dotnet /usr/local/bin/dotnet
restart omnisharp & restart vscode
No need to do anything. Just close and re-open. It will work.
I also faced similar problem. In my mac os cmnd + 'click' is used to 'go to definition' then it suddenly stoped working. If that is the case then please follow these steps:
restart vs code
restart pc
uninstall all extensions and reinstall again followed by a pc restart.
I had a similar issue with the extension C/C++ installed. I solved it by downloading an older version of the extension and upgrading to the last version. Somehow it solved the problem...
I have been trying out using Eclipse CDT for a course I am taking. Previously I have been using Visual Studio Express but since that requires me to be online and I have to use the IDE+compiler offline, I switched to Eclipse + Cygwin GCC.
Now everything was working prefectly, until I got an error about file paths in my make file. After reading some of the posts online, the issue seemed to be that Cygwin's make does not resolve absolute Windows file paths because of the ':' symbol and confuses it with a new target definition. The proposed fix was to download a fixed make file. I diligently did so and the programs would compile fine.
But after I went into the first debug session, everything froze. I aborted eclipse and tried a clean build but now the compilation wont happen AT ALL, which is very weird for me.
I can't find a post for a similar problem so I am really stuck now. I was currently working the assumption that my CDT may be corrupt or something so I downloaded Eclipse Luna just today and tried building using that, but no joy. Even a fresh project in a new workspace wont compile.
Appreciate the help in advance.
Did you try redownloading Eclipse? Sometimes Eclipse gets a fatal error glitch that makes it unable to compile anything. I've had this problem before, the only way i was able to fix it was to uninstall and re download the latest version. If this doesnt work, try switching to Bloodshed Dev C++ or codeblocks.
So it seems like an issue with the new make (v3.80). upgating it to v4.08 fixed the issue of not building.
Version 4.08 however does not fix the Windows file paths not being recognized properly and treated as a target definition. I am still getting the multiple target patterns. stop error.
EDIT: Found this on Stack overflow to solve the issue... should have searched better previously.
Very simple application fails with "multiple target patterns" from Eclipse
I am trying to get the NetBeans IDE to work with the g++ compiler. I am downloading from cygwin. I've tried googling the problem and I have tried many things to get C++ to work on NetBeans. I can't figure out the magic trick so I am asking for your help.
I have two problems, I don't know if these problems are related to each other.
Problem one: I get this error when I try to run my small program.
Problem Two:I get a "Cannot find include file <iostream>". When I hold ctrl and hover over the include directory my compiler says Unresolved directive #include<iostream>
I followed this NetBeans Guide on how to install and configure C++ support. Following those directions I had received the two errors above.
Here is what my environment variable looks like: this
Here is what the C/C++ build tools look like for NetBeans: this
Here is the code I am trying to run; this
At the moment I am installing everything from the development tab in the cygwin setup program.
I've tried messing with different settings but the two problems were still there.
I've tried running NetBeans in admin mode but the two problems were still there
I've tried un-installing cygwin and installing minGW. That fixes problem number one, but the there is no output when the program runs.
I've tried adding C:\cygwin64\lib\gcc\x86_64-pc-cygwin\4.8.2\include\c++ to the "Include Directories and Headers" in Properties -> Build -> C++ Compiler. This resolved iostream, but the other directives under iostream had the same problem, that the other include files could not be found.
I've been at this problem for five hours or so. Any help would be appreciated.
Here is what I am running:
Windows 7 64 bit
NetBeans 7.4
If you need anything else, just ask.
The answer was that my firewall, comodo firewall, was sand boxing the files that needed to run. After disabling the sand boxing feature NetBeans ran fine.
Few days ago I had to reinstall all my Linux system, and I also had to reinstall Eclipse CDT as I used to work with it since few weeks.
Unfortunately, since then I do not have live error checking anymore... and I miss it ;)
If I create a new Hello World C++ project (New / C++ Project / Hello World C++ project) and then add some errors like calling a method from an nonexistent class or adding any undefined or untyped variable, well Eclispe doesn't underline and report them as it was doing before I had to reinstall it all.
I searched stackoverflow, and tried to deactivate/reactive "Build automatically" without any change. I also verified that the project path is included in the project sources (Project properties / C-C++ general / Path and Symbols / Source Location) but as it already was, it didn't solved the problem.
When I "Build All" the errors are well reported in the "Problems view", and then when I fix one problem and save the file, the error disappear from the Problem view, but then if I add another problem and save, nothing is reported until I build again. Even errors turned to comments still remains underlined until the next "build all".
Do you have any idea to help me reactivate this feature ?
I was under Eclipse Linux 3.5 and I now use Eclipse Linux 3.7.
I installed the Eclipse package: Eclipse C/C++ IDE Indigo SR-1 with Eclipse Platform 3.7.1 and that fixed the problem.
So I guess, there was a problem with the 3.7.0 currently provided by the Ubuntu Software Center.
With this new version all is Ok by default.
