Update to latest c/c++ standards we recognize

[Raspredval]

Enabling the make extention breaks the include paths, specified in the c_cpp_properties.json: "includePath". It asks to configure something intellisence related when the extension is loading; that's exactly what breaks intellisence to stop looking for those additional include paths. But if you manually disable the make extension, reload vscode and enable the extension back it starts working again.

I'am using the latest makefile-tools extension, the release version of c/c++ extension (although this keeps breaking in the pre-release version as well) and this is my vscode version:

@Raspredval Thanks for the feedback!

What is that you're trying to accomplish with the manual includePath in the c_cpp_properties.json? @andreeis Correct me if I'm wrong, but if you're using this extension you should be able to let the Makefile extension configure intellisense for you, rather than manually specifying it in the c_cpp_properties.json file.

Are these includePaths paths that are not found by make and you had to set them manually because of that?

Thanks! Any information to help us repro and/or diagnose this is great!

[Raspredval]

maybe I'am using this wrong, but "includePath" works only for the intellisence. The include paths that I use for building work just fine, the build process is not affected. It's the intellisence that's breaking. Basically it stops parsing theese additional include paths and shows a lot of errors, as if it failed to include the files.

[bobbrow]

One of the primary goals of this extension is to automatically provide the includePath to the C++ extension so that you don't have to manually specify it. When that happens, the includePath you set in c_cpp_properties.json is not used. If the Makefile Extension is not providing the correct paths for IntelliSense, then you can disable that part without disabling the whole extension. (and of course, we'd like to learn more about your project to understand why we failed to provide the correct information for IntelliSense in the first place).

To disable the automatic IntelliSense configuration, you should either:

• remove the "configurationProvider" entry from c_cpp_properties.json, or
• delete the "C_Cpp.default.configurationProvider" setting from settings.json

[Raspredval]

oh, I didn't know, it does that, thanks! I'll try to remove the config file and reload the extension, maybe it would get the include path for me

[Raspredval]

and it didn't work. Is there a specific way I have to structure the makefile for this to work? Anyway, I would probably disable the automatic configuration and provide the paths myself. Thanks for answering <3

We have a troubleshooting guide here: https://github.com/microsoft/vscode-makefile-tools/blob/main/docs/troubleshooting.md We also share known good configurations for popular open source repositories here: https://github.com/microsoft/vscode-makefile-tools/blob/main/docs/repositories.md

If you want to run the C/C++: Log Diagnostics command and share the output here, we can see if anything obviously wrong is happening.

We could also take a look at your logs if you want. Set the "makefile.loggingLevel" setting to "Debug" and then reload the VS Code window. The logs will show up in the Output panel (choose "Makefile" from the drop-down box)

I think it doesn't parse the include paths because I'am using the -isystem flag instead of -I. And there's a valid reason to do so: isystem tells the compiller to ignore any warnings in the included files. Since it's a well known third party library (wxWidgets) it's probably fine to ignore the warnings

Yes, I believe you are correct. I don't see an issue about -isystem support, but we should have one if this is not working correctly. I'll reopen this issue.

[Raspredval]

ok, if you're planning of adding support for -isystem, then you probably should expand it to support a couple more flags: https://gcc.gnu.org/onlinedocs/gcc/Directory-Options.html#Directory-Options

[bobbrow]

We support it in the C++ extension, and I had thought that we pass-through additional flags that don't have explicit support yet. If you would be willing to enable the automatic configuration again briefly, I'd like to see the log from the C++ extension with that on. The result of C/C++: Log Diagnostics you shared earlier appeared to be without the automatic configuration enabled.

You can run the C/C++: Change configuration provider command to quickly switch it on and off.

[andreeis]

@bobbrow, look above in the makefile log, -isystem and the following argument look correct in compiler arguments, do you confirm? CppTools receives them as it expects. @Raspredval, something else is the problem here. We do not support yet wildcards in filenames. The use of *.cpp we parse correctly but we should expand it and send to CppTools an individual configuration entry for each cpp file we find on disk at that location. I believe that is why IntelliSense doesn't work. Is it easy for you to modify the makefile so that when make process it it displays the file names in the log? If you confirm this is the root cause, I will close this as a duplicate (searching in the meantime for the main work item that tracks wildcards).

[andreeis]

https://github.com/microsoft/vscode-makefile-tools/issues/156

[Raspredval]

sorry it was pretty late yesterday. If I get it right, you want me to unroll the *.cpp into individual filenames. Doing so does in fact solve the issue: the extension correctly identifies the include paths for the intellisence

[Raspredval]

So, I've been poking around, and worked out a solution for the wildcard thing: I used the shell to unroll it for me right in the makefile. Lets assume we have several source (.cpp) files in the source dir. Then we can use the $(shell ...) feature of make to unroll the *.cpp into a list of filenames. Then we can use this list as a compile argument and the make extension would successfully pick them for the intellisence:

SOURCE_DIR=__some_source_dir__ SOURCE_FILES=$(shell ls "$SOURCE_DIR"/*.cpp) OUTPUT_DIR=__some_output_dir__ all: g++ $(SOURCE_FILES) -o $(OUTPUT_DIR)/out

[Raspredval]

BTW, it looks like the make extension doesn't recognize the c++ standard version from the makefile and then overrides the user settings for intellisence with the default value of c++17. Maybe you can use the user settings value instead of the default value if it failed to parse or something.

[andreeis]

@Raspredval , we are behind with standard updates. Thanks for pointing that out. We will quickly include 23 to the recognized list. Quick fix, will make it into 0.7 release (next week if all goes well). I will leave this work item open to track this standard update in our code base and will change title.

Regarding wildcard, I mentioned earlier the link to the work item that tracks our intention to expand the * in whatever the current folder we calculated we are in, grab all the c/c++ files we find and create a configuration entry for each with all that we parse from that compiler command. Future release, we didn't triage yet when.

It's great that you found the convenient workaround with the $(shell) construct. That reminded me that we have another work item that got pulled out of 0.7 (because of some safety and testing we need to do more) but will make it into 0.8, regarding safe commands (expanding `) which will also be able to achieve this (not supported on windows since backticks have different meaning on that system).

Quick question (I can also check myself later): the $(shell) construct in a makefile works on windows as well? If you change ls with dir, of course. If you happen to know or is handy to try. I'll find out soon.

The backtick work item is this: https://github.com/microsoft/vscode-makefile-tools/pull/409.

[Raspredval]

thanks, I can try setting up a virtual windows machine, but it probably should work as well. https://www.gnu.org/software/make/manual/html_node/Shell-Function.html

[andreeis]

@Raspredval , no worries , don't setup a windows vm, I got my answer. Thank you for the link.

[andreeis]

@Raspredval, @gcampbell-msft merged in a fix for your request and will be released with 0.7 next week but if you would like to see how this works earlier you can install one vsix from this link.

go to the Extensions panel on the left click "..." run "Install from vsix" from the context menu

Let us know if you encounter any other issues or if you have any other suggestions/recommendations for this extension.

[Raspredval]

@andreeis I've tried it and it still requires unrolling the wildcard (via $(shell ...)) or by hand. But the standard bug got fixed, it now recognizes the -std=c++20 (but not the -std=c++23, which IS supported by c++ extension) flag. Plus there's another issue: the make extension applies the extracted settings only for the source files listed in the build command. For example, I have an aggregate header file, that gathers all the common system includes: that header works just fine if it's included in one of the source files, but doesn't work on it's own then it's not included in any of the source files.

[andreeis]

@Raspredval, I didn't mean that we fixed the $(shell) part :), only the c/c++ standard part but thanks for you trying out the vsix and letting us know it doesn't work for 2023. This way we realized we missed one piece and submitted an update PR. Regarding the header, it is by design that we don't see it when standalone but only when included in another c/c++ source file because only then it becomes a translation unit. Any design change regarding how IntelliSense works for standalone headers would belong to CppTools (our sister extension), not Makefile Tools.

[andreeis]

Forgot to close this one. 0.7.0 is released and unless I overlook anything, all the issues touched in this ticket are either answered or by design / won't fix or fixed and released. Please reactivate if there is anything I missed.
