Bug Summary and Steps to Reproduce
Bug Summary: https://github.com/microsoft/vscode/issues/209982 Not sure is ext problem or VSC
Steps to reproduce: Use any c code like
#include <stdio.h>
int main() {
// printf() displays the string inside quotation
printf("Hello, World!");
return 0;
}
Expected behavior: I expected to see function lists and class, etc. like on python.

Additional context

Are you saying that IntelliSense isn't working correctly? Could you provide a screenshot of the issue you are seeing?
So there could be a few things here:
-
I am not sure your .c file has been opened correctly, it looks like it is missing the c symbol I usually see:
-
This would seem to suggest and IntelliSense issue. Could you provide output from the C/C++: Log Diagnostics command you would have access to once you open the file?
-
Do you have access to any other IntelliSense features (i.e error squiggles)?
Let me see.. I added test2.c file where have problem. Will be great to see your file. Maybe is coding problem.. not sure. But is strange. test2.zip
@ManPython Symbols might not be found if there's some issue with your database. You can set C_Cpp.loggingLevel to "Debug" and look for database error messages, and/or run the C/C++: Reset IntelliSense Database command, and/or add this setting to your workspace's settings.json: "C_Cpp.default.browse.databaseFilename": "${workspaceFolder}/.vscode/browse.vc.db" and verify that the database is created successfully.
Don't understanding nothing here : )
- Soo.. symbols are in database for each language? Where?
- I tried re-instal extensions as related c/c++ and nothing.
- The test.c code is not only for c/c++ but also for ca65 cl65 as ASM to include.. soo.. should be independent I think in relation to
"${workspaceFolder}/.vscode/browse.vc.db - C_Cpp.loggingLevel to "Debug" and look for database error messages ..but no errors around (F1 > Open View... > Shared
- "C_Cpp.default.browse.databaseFilename": "${workspaceFolder}/.vscode/browse.vc.db" and verify that the database is created successfully. - where this database should be created, how to check, I do this but not see sense here
@ManPython Our C/C++ extension creates a database of symbols for C/C++ files for the Outline view. It's normally storied in some default location, but you can override that default location to put the database in your workspace folder (perhaps temporarily) to see if that fixes the issue and/or if the database is being created or not. With that setting set, the database should be in the .vscode folder of your workspace folder, the same folder that might contain a setting.json or c_cpp_properties.json files if you've modified those settings.
Ok, got it.. but.. base exist, and some issue around coding? Or it's normal?
@ManPython What do you mean by "base exist"? Do you mean the bug still repros? Your screenshot doesn't show anything unusual. The "code_items" table is where you should seem symbols.
Data base exist. Symbols list not exist. Soo.. if no symbols, then some type of bug.. Did you try my file? Sent me other own example to check how can be done data base on this.. if possible.
@ManPython Did you look for database or tag parsing errors in the "C/C++" logging pane? This one:
In output I dont have C/C++ when .c But.. I save .c file as .cpp and symbols exist (and then I have in combolist C/C++), so it's problem only when .c file as extension.
@ManPython We just found a bug with 1.20.1 (i.e. we reproed this bug) -- you should try downgrading to 1.20.0 or 1.19.9.
@ManPython Oh, sorry -- it turns out I was reproing a different issue. You're using the x64 vsix, right?
Yeah, that should be the x64 vsix.
We don't currently know what could be causing this failure, but the symptom is similar to a tag parser failure which could be caused if vcmeta.dll can't be loaded by our cpptools.exe process. You may want to verify vcmeta.dll exists at C:\Users\username\.vscode\extensions\ms-vscode.cpptools-1.20.1-win32-x64\bin\vcmeta.dll in case it's being deleted externally.
It's also possible that your OS is missing an expected DLL that vcmeta.dll needs to load. I'm not sure which DLL that would be. It's possible the Windows dependency walker could tell.
Exist ver. 14.38.33135.0 But if working with cpp then is just case for c not .dll I think.
@ManPython You're right -- a problem with vcmeta.dll would affect cpp files too. I'm not sure why there would be a failure just with c files (which we're not able to repro so far).
I'm suggest to produce test example as .cx or .cc extension to see it's VSC problem or not.
