• VSCode Version: 1.0.0
• OS Version: windows 7

Steps to Reproduce:

1. In one header create warning message
2. Include this header into multiple files
3. Compile and go, to problem Mach in this header
4. Problem message shows a list repetitive messages

It is strange to see list of problem messages that are the same.

Additional Include Folders would be great for IoT development.

In OSX I noticed that any std headers were not found by default so I had to add to the include path:

/usr/include/c++/4.2.1

Similar to how #IF is currently supported, it would be great if also #IFDEF worked.

Here's an animation to clarify.

This is (partly) a duplicate of #26 and #24. On Linux the default include path is "/usr/include" which is fine for standard C programs. However, the C++ STL is missing by default (see #24) and has to be included in c_cpp_properties.json manually. Once this is done Visual Studio Code will start parsing the newly found includes (I assume those in /usr/include as well) which somehow makes the rest of the OS absurdely slow - even vim takes ages to respond. I assume this is due to high disk usage.

If I leave the system alone it will take about an hour until parsing is completed - resulting in a database file which is about 1GiB in size per project. This is where #26 kicks in: if I close and reopen Visual Studio Code the old database will be deleted and the whole process starts once again.

Not parsing the default includes is possible but those "include not found" warnings get annoying very fast.

• VSCode Version: 1.1.0
• OS Version: OS X Version 10.11.4

Steps to Reproduce:

1. Write the following code

    int array[] = {9, 8, 7, 6, 5, 4, 3};
    int size = sizeof(array)/sizeof(int);
    for (int i = 0; i < size; i++)
    {
        fprintf (stdout, "%d ", array[i]);
        fflush(stdout);
    }

1. output should be:

9 8 7 6 5 4 3

however the output is

8 7 6 5 4 3

The '9' is lacked.

Task.json is created as the followings:

            "severity": 4,
            "message": 5
        }
    }
}

However it report the following error, though there are MergeSort.cpp and test.cpp in the working dicrectory:

clang: error: no such file or directory: '*.cpp'
clang: error: no input files

Microsoft.VSCode.CPP.Extension.linux is a 64-bit binary, so can not work on my 32-bit ubuntu 14.04 OS.

The documentation and examples for launch.json show the use of an object list (key/value pairs in {}) called 'env' for passing environment variables to a debugging session.

But on my version which I installed yesterday, it's an array ([]) called environment. Hovering over it to get Intellisense gives a description that corresponds with above.

How can I pass environment variables to the debugger?

Similar to how the extension C/C++ Clang supports code completion, wouldn't this be within the scope of this extension?

I see you're storing a lot of information in a .browse.VC.db file.
This files takes hours to generate on large projects. You can imagine my dismay when I realized that you're deleting this file, and recreating it from scratch every time I restart code.

This happens on Linux with version 0.5.0 and vscode 1.0 and 1.1.0.

If I have a C file open, and it contains a function, and I click "go to definition" of that function, no matter from what open file (even from the same file) - this will cause the C file containing the function to be re-opened and appear twice in the active files list. The second file appears with the file's absolute path next to it.
This is confusing and causes clutter. I'm not sure if it's a bug in the extension or of vscode itself.

Attached - example of how it looks.

I attempted to use the C++ Attach feature of Visual Studio Code using gdb on Linux Mint 17.3 and it did not work. I created a simple helloworld application. Launching the application for debugging (C++ Launch) worked fine but attaching to an existing process did not. I placed a cin statement in to ensure it was paused while I did the attach. Here's the console output:

• OS Version: Mac OS X 10.11.4

Hi, I am trying to debug my program with the following configuration:

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "C++ Launch (GDB)",
            "type": "cppdbg",
            "request": "launch",

            "cwd": "${workspaceRoot}/build",
            "environment": []
        }
    ]
}

When I try to run this configuration I get the error: spawn <home>/.vscode/extensions/ms-vscode.cpptools-0.4.2/debugAdapters/corerun ENOENT. Stopping the debug adapter.

Can't seem to find this issue anywhere else. gdb is signed and works on the command line.

Steps to Reproduce:

1. Try to launch debug configuration

Any help would be greatly appreciated. Thanks!

The extension should allow adding custom preprocessor definitions to c_cpp_properties.json. This would allow achieving the same results as with C++ /D compiler flag (https://msdn.microsoft.com/en-us/library/hhzbb5c8.aspx).

VSCode.Cpp.Extension.exe (v 0.5.0) is keep using network about 9Mbps steady number (in task manager), maybe I'm using samba mounted disk from my Linux box for my project.

• For testing, left it with no source file opened.
• After uninstalling this extension, my HDD is now quiet.

From 白乐航 - User review comment on extension market place page

This is what I have been looking for something lightweight,C++ compiler.Much love~ support Chinese,support windows.

I have explicitly excluded some directories from my workspace in settings.json.

These files do not show up in the explorer, but when I search for symbols I see you're searching the excluded folders.

Looking at the .db file using sqlite3 I can see you have included files that are excluded in my settings.json.

the settings.jason content is the following:
// Place your settings in this file to overwrite default and user settings.
{
// The number of spaces a tab is equal to.
"editor.tabSize": 3
}

when i open my C project (not a C++), then the tabSize is ignored.
VSCode indicates that tab size is '6'. I have to manually change the tab size to the 'configured tab size'.

Would be great to have Find all references working. Huge helper in large projects.

Please support Visual C++ Build Tools 2015 for debugging:
https://blogs.msdn.microsoft.com/vcblog/2016/03/31/announcing-the-official-release-of-the-visual-c-build-tools-2015/

Please i'm a new coder, please make a windows debugger version, it's so important

I've been through all the issues and there are many (both open and closed) that seem to report this bug and its associated behaviours but aren't linked:
#44 #39 #29 #26 #11 #6 (closed as duplicates #25 #14)

The problem: After installing the extension, as soon as you generate the c_cpp_properties.json file to declare the standard linux include location /usr/include, the extension goes off and builds .browse.VC.db (the symbol database) in the .vscode workfolder directory. This however takes hours to build and becomes a 1-3GB symbol database of what I can only imagine is the entire system's libraries. And it's created for each workfolder, and recreated in each workfolder everytime the project is opened. Even if it's just a simple hello_world.c. If you close vscode, the extension continues running, building this database with associated network, cpu and hdd activity.

This makes the extension unusable on linux.

Tried extension on Windows and the .browse.VC.db stays at small size.

vscode: 1.1.1
cppext: 0.5.0
distro: Archlinux
(I appreciate it's only officially tested on Ubuntu, and haven't tried to replicate on a Ubuntu distro)

As an aside the link on the blog post to this github repo is incorrect (missing an s)

1. Install the extension and open a cpp file to start intellisense.
2. Uninstall the extension
3. Check the .vscode folder or look at the running processes

EXPECTED: extension is removed
ACTUAL: Microsoft.VSCode.CPP.Extension.exe is left behind because it is running.

Perhaps the inverse to #15; to be able to view an entire call hierarchy of a function.

Seen it implemented in Eclipse.

This was copied from the reviews on the extension page. Not sure if it is a language service issue, or a debugger issue.

From the original blog post, I know that includePath is an available option. What else is there?

Multiple comments on various forums

1. Install VSCode c++ extension
2. Any workspace I open in vscode will get modified, even if it does not have C++ -> files will be added inside the .vscode folder

Optimally the extension would not touch the content of any workspace.
If that is not possible the extension should only touch the content of C++ workspaces. I believe this could be achieved by being activated on the event onDebug:cpp. This event will be availble in the April release.

Hi,
I've been testing the new C/C++ extension, however I am running into some problems with code completion suggestions.

Here is an example with C/C++ extension installed, forcing suggestions using cmd+space.
It results in perpetual "Loading..." pop up:

With the extension uninstalled, the suggestions show up immediately

The features like go to symbol and go to definition are working properly with the extension installed,
however it seems to hinder the code completion.

Hi,

It would be nice if the vscode C++ extension had a Toggle header/source feature.

Actually, I've already implemented such a feature bbenoist/vscode-togglehs but it would be better if it was directly available from the official extension IMO.

Extension has 939 installs, which means the feature actually has some audience.

Hi,
I have installed cpptools but Intellisense and symbols view is not working at all. Search for symbols command always displays "No Symbols Matching " message. I was wondering are there any dependencies to make it work for Windows?

Thank you,
Regards,
Raj

Searching for a symbol in very large C Project using Show All symbols command(Ctrl+t) is very very slow. Find In Files option is quicker than the show symbols command.

System: Windows 7 and .browse.VC.db file size approximately 1.1GB .

i install the c/cpp extersion by copy the .vscode/extersions/ms-vscode.cpptools-0.5.0 folder to a pc which can't connect to internet.
this pc use win 7, after install, ctrl+shift+o show "we have no symbol information". and cannot find "go defintion" on right button menu, and the staut bar show text "undefinedwin32".

on ubuntu 14.04
when trying to debug, causes this error:
launch: program '/home/leon/visual-studio/a01.cpp' does not exist

This ext cannot run on my XPS13 Win10 laptop even after the VS2015 Runtime package has been installed.

If you are a Windows user (Win7 in my case), and don't have Microsoft Visual Studio Redistributable 2015 x86 installed on your system the extension does not work at all.
But the bug itself is the lack of information about it. Some people is complaining that the extension does not find any symbols and seems that this may be the cause.

If you manually try to run
~\.vscode\extensions\ms-vscode.cpptools-0.4.2\bin\Microsoft.VSCode.CPP.Extension.exe
You'll get a dialog with the error of "MSVCP140.dll" not found.

It would be great to get info about this error when the extension is being loaded from vscode, otherwise you are not aware that something went wrong.

Thanks !

• VSCode Version: 1.0.0
• OS Version: Ubuntu 14.04 LTS

Steps to Reproduce:

1. Open an NFS mounted folder in VS Code with a mix of C++, js and python source code (1000's of files)
2. Let the parsing (indexing) begin i.e. creation of the symbols database for intelliSense

It is really slow (it's been running for 4 hours). This isn't the case with a similar setup with Sublime Text 3 on the same NFS mounted folder.

For some reason VS-Code always complains that it cannot find the fstream header even though all other C++ standard library headers work perfectly fine. For example, the following code reproduces the issue:

#include <fstream>  // "Include file not found in include directory"
#include <iostream> // no errors...

This happens on both Windows (using Visual Studio includes) and OpenSuse even though the fstream header is present in the include directory.

from Xaver Hellauer - Review comments on extension's market place page

One thing still needs to be fixed: In my opinion, the extension should not load and produce its helper files when non-C/C++ projects are open.

Thanks team for this pretty good extension.
It works on the latest Kubuntu 16.04; Vscode 1.1.0-insider

Will the xterm dependency be eliminated?

• I'd rather pipe stdout/err to vscode's debug console, just like on gdb;
  (the Python extension does it)

Bug:

• Redirecting a file as input source is currently not functional; e.g. by setting "args": [" < input.txt"], in launch.json
