"go to definition" function doesn't work on vs code for c/c++

[wafei]

hello, i can't figure out how to get the function( "go to the definition" ) working.

i already installed the extensions: the c/c++ extension(0.18.1), the c/c++ clang command adapter(0.2.2), the c++ intellisense(0.2.2). and the command gtags or clang works well.

I don't know why doesn't work the vs code behavior to 'go to definition' when I do 'command + click' or 'F12'.

vs code version: 1.26.1 os version: windows 10 x64

many thanks for your help

We're going to need a little more information about your workspace to answer that. If you have a c_cpp_properties.json file in your ${workspaceFolder}/.vscode folder, can you please share that? Is the definition you are trying to navigate to defined in a source file under your ${workspaceFolder}?

i do have a c_cpp_properties.json file , the 'includepath' is generated automatically. and the definition is in the source file under my ${workspaceFolder}, but when i do 'go to the definiton', it showed me 'no definition found for ... '

Are you trying to do goto definition on a local variable (in a function)? That doesn't work yet and #255 will address that.

[wafei]

local variable doesn't work, but global variable neither

[wafei]

so strange, the function works well in a minor project, maybe it can't work when the project is too complex?

[bobbrow]

It is also possible that macros are interfering with the tag parsing of the global variables. Is the source code public? Can I download it to check?

[wafei]

i have done nothing, but today it all works well, confused

[bobbrow]

Perhaps the extension took a long time indexing the files. We display a database icon in the status bar while the source files are being parsed.

Let us know if you continue to have any problems in the future.

two functions are defined in the same file and are called in another file, go to definition works for one function, while does not work as expected for the other function. Maybe sometimes, it can work.
