Have installed C/C++ extension but its not working as expected

[basava157]

Hi Team,

I have installed C/C++ extension in remote desktop and its showing as "Extension is enabled on SSH : IP address'. But the issue is when we start browsing code its not working as expected. when we click on "Go to definition/declaration" it will struck and always showing like loading only.

No feature working for browse code. So please help on this.

@basava157 There might be some problem with the database. Can you set C_Cpp.loggingLevel to "Debug" and look in the C/C++ logging window for any database error messages? Also, can you set C_Cpp.default.browse.databaseFilename to something like "${workspaceFolder}/.vscode/vc.db" to verify that the database file can be created (it might be trying to create it at an invalid location).

Log generated by C/C++ extension output window content: "Warning: Expected file /home/basavaraj.m/.vscode-server/extensions/ms-vscode.cpptools-1.20.5/bin/libc.so is missing."

It looks like in home direcory, inside the /.vscode folder there is no db file. sh-4.4$ ls .vscode/ extensions.json sh-4.4$ cd .vscode/ sh-4.4$ ls extensions.json

Note : one more observation is when we reconnect it will show every time like : "The C/C++ extension installed does not match your system."

Installed extension pack details in remote machine are : sh-4.4$ cd $HOME/.vscode-server/extensions/ sh-4.4$ ls arzg.eclipse-0.2.0 extensions.json ms-vscode.cmake-tools-1.18.42 ms-vscode.cpptools-extension-pack-1.3.0 davidanson.vscode-markdownlint-0.55.0 mitaki28.vscode-clang-0.2.4 ms-vscode.cpptools-1.20.5 ramyaraoa.show-offset-0.0.4

The machine details are: The local machine is Microsoft Windows10 pro The remote machine is ubuntu 18.04 Linux.

(Tried with different extension but still not working and getting same error so please suggest the correct one)

@basava157 You have an extension that is for the wrong OS installed. You should uninstall your extension, reload window, and then install the Linux version of the extension in the remote instance. The marketplace is supposed to handle this correctly. Did you install it via the vsix on the GitHub page?

[basava157]

Ya correct, I have installed manually through VSIX / command prompt. As you suggested if its not correct version means, could you please suggest which is the compatible version for this platform. Automatic installation is not working from extension option, so tried doing manually.

When we try to reinstall with latest version getting error as "XHR failed"

and also, When I try to install Linux extension getting below error.
