IntelliSense not checking for error for some file in the same project about vscode-cpptools HOT 4 OPEN

Hi @cosmo86 . Can you provide the output of the C/C++: Log Diagnostics command, with the repro'ing file open? That should indicate how IntelliSense was configured for the file.

Are there any errors prior to the line you're expecting to see one on? It's possible there may be prior errors in headers that are preventing later code from being parsed properly, or altering the context in which that code is interpreted (such as an immediately previous class missing a semicolon, or missing closing brace or bracket, for example).

Can you provide a zip file containing a stand-alone repro that we could investigate further?

from vscode-cpptools.

@Colengms Thanks very much for the reply!!
here is the log from one of the many files that has Intellisense issue, i will provide another log from one of the file which Intellisense works normally.

Note: I would love to provide you with the full repo, but here are trade-related sensitive info in the repo(as you might have gussed from the name of the files). So I probably cannot provide the full repo at this moment.

However, if the Log Diagnostics is not enough for you to debug the issue, I can try to de-sensitize the code and send you a copy.
Again thanks a lot!

@Colengms As for this point you raised "Are there any errors prior to the line you're expecting to see one on? It's possible there may be prior errors in headers that are preventing later code from being parsed properly, or altering the context in which that code is interpreted (such as an immediately previous class missing a semicolon, or missing closing brace or bracket, for example)."

The answer is no. I consider myself a noob in c++. But for this issue, I have chacked carefully that there is no issue prior to my intended "a=1" error.
I also build my code using cmake and all moduels works as intended.

Hi @cosmo86. In your logs, I see the following:

------- Potential include path issues --------
Some headers exist in multiple locations. If IntelliSense is behaving incorrectly,
try adding one of the alternate paths to the "includePath" in your configuration in
c_cpp_properties.json to override the automatic path discovery for that header.

Using: /opt/rh/devtoolset-7/root/usr/include/c++/7/algorithm
Alternative: "/root/usr_1/thrid_party_package/cmake-3.28.1/Utilities/std/cmext"
Alternative: "/root/usr_1/thrid_party_package/cmake-3.28.1/Utilities/std/cm"
...

These ambiguities could easily result in IntelliSense choosing the wrong files, which could lead to errors prior to the code you expect to see the errors in.

It's unclear to me from your latest logs, but your initial issue referred to:

            "includePath": [
                "${workspaceFolder}/**"
            ],

Are you perhaps opening /root/ as your workspace folder? If so, you might consider scoping that down to opening only the nested folder containing your immediate project, so you're not pulling in header files for unrelated projects into your include paths.

Or, consider being more explicit with the contents of your includePath setting, to only refer to the specific include directories you use when building the code.

Or, if you're using CMake and CMake Tools, I'd suggest setting "configurationProvider": "ms-vscode.cmake-tools" in your configuration, to allow IntelliSense to be configured by your build system, which would use the same include paths as your build and shouldn't lead to those header ambiguities.
