Std::map error

Newbie
1

Hi,

What’s wrong with this code? ROOT version is 6.27:

std::map<std::string, int> m{{"CPU", 10}, {"GPU", 15}}
IncrementalExecutor::executeFunction: symbol '??$min@_K@std@@YAAEB_KAEB_K0@Z' unresolved while linking function '_GLOBAL__sub_I_cling_module_24'!
You are probably missing the definition of unsigned __int64 const & __ptr64 __cdecl std::min<unsigned __int64>(unsigned __int64 const & __ptr64,unsigned __int64 const & __ptr64)

Maybe you need to load the corresponding shared library?

ROOT exited after this error.

2

Which code? can you provide a minimal macro producing these error messages?

3

I think I already provided the std::map initialization line that had error in the interactive shell, shown above. You mean run it a macro would make a difference?

4

Which operating system and compiler versions?
How have you installed ROOT?

5

This is a binary build.

@shu11 Try to take the latest pre-built nightly binary .

@bellenot Looks like a Windows problem.

@shu11 it works for me:

root [0] std::map<std::string, int> m{{"CPU", 10}, {"GPU", 15}}
(std::map<std::string, int> &) { "CPU" => 10, "GPU" => 15 }
root [1]

Can you tell which version of Visual Studio you have on your computer?

I see my problem from your run: I didn’t run the thisroot.bat. That’s why I got those errors. After I ran thisroot.bat, the errors are gone.

By the way, I am using this VS:

** Visual Studio 2019 Developer Command Prompt v16.11.3
