range-v3 issue

[grishalipenko]

Type: LanguageService

Describe the bug

• OS and Version: Linux x64 5.4.0-56-generic
• VS Code Version: 1.51.1
• C/C++ Extension Version: 1.1.3

Steps to reproduce
I have code:

#include <range/v3/algorithm/all_of.hpp>

......

    if (ranges::all_of(v, [](bool val) { return val; })) {
        publish();
    }

And I get message:

no instance of overloaded function "ranges::all_of_fn::operator()" matches the argument list -- argument types are: (std::vector<bool, std::allocator>, lambda []bool (bool val)->bool) -- object type is: const ranges::all_of_fn

With another ranges same problem about "no instance".

How I can avoid this problem?

Hi grishalipenko (@grishalipenko) . Thanks for reporting this. The issue also repro's in VS. (We share code for IntelliSense with VS). I've opened a bug against VS.

Fixed with https://github.com/microsoft/vscode-cpptools/releases/tag/1.3.0-insiders

[grishalipenko]

I installed 1.3.0-insiders from VSIX. And squiggle reproduce:

no instance of overloaded function "ranges::all_of_fn::operator()" matches the argument list -- argument types are: (std::vector<bool, std::allocator>, lambda []bool (bool b)->bool) -- object type is: const ranges::all_of_fn

I can add screenshots if needed.

Another example:

no instance of overloaded function "ranges::minmax_element_fn::operator()" matches the argument list -- argument types are: (const std::vector<int64_t, std::allocator<int64_t>>) -- object type is: const ranges::minmax_element_fn -- detected during instantiation of function "lambda []auto (const auto &v)->auto [with =std::vector<int64_t, std::allocator<int64_t>>]" at line 149 C/C++(304)

auto [min, max] = ranges::minmax_element(v);

It's fixed for me on Ubuntu 20 with g++ 10.2 and the latest https://github.com/ericniebler/range-v3 (and with cppStandard set to c++20). What g++ version are you using? What version of the range-v3 library are you using?

The code auto [min, max] = ranges::minmax_element(v); doesn't compile for me with g++: error: ‘minmax_element’ is not a member of ‘ranges’; did you mean ‘bind_element’? 11 | auto [min, max] = ranges::minmax_element(v);
