to_string(double&) is ambiguous

[AlconDivino]

Pretty much the Title. When compiling i get the error

Call of overloaded 'to_string(double&)* is ambiguos'

from binacpp.h.

Using Win64 and Codeblocks.

Any suggestions?

See this discussion:

https://discuss.codechef.com/questions/87478/to_string-function-in-codeblock-not-wrorking

Chances are:

• You have not set the proper C++11 compiler flags
• You set the right compiler flags, but your Codeblocks version does not support C++11

[AlconDivino]

Thank you i seriously forgot to set the Flag 🤦‍♂️

But i got another issue. I Included everything and also linked every library. Why do i get the Error

undefined reference to `BinaCPP::init(std::cxx11::basic_string<char, std::char_traits, std::allocator >&, std::cxx11::basic_string<char, std::char_traits, std::allocator >&)'|

I can't seem to understand it :/

EDIT: I didn't want to start a new issue here :D

[alexanderkoumis]

Did you compile binacpp as a separate library and link that to your own program? Or did you try to compile your program along with all of the binacpp sources?

[AlconDivino]

tried to compile binacpp seperatly and still getting that ambigous error

Any idea?

[alexanderkoumis]

I'm guessing it has something to do with spotty support for to_string on MinGW's side. You can try implementing this patch for now (found here):

#include <string>
#include <sstream>

namespace patch
{
    template < typename T > std::string to_string( const T& n )
    {
        std::ostringstream stm ;
        stm << n ;
        return stm.str() ;
    }
}

#include <iostream>

int main()
{
    std::cout << patch::to_string(1234) << '\n' << patch::to_string(1234.56) << '\n' ;
}

You will have to add the patch:: namespace to all the calls that fail to make sure your modified version is called. Or do a search and replace in Codeblocks to replace all to_string calls to patch::to_string.

[AlconDivino]

Thanks :D

[AlconDivino]

No does not work. On Stack overflow i was told to reopen the issue.

I still cannot compile the Library for my system because apparently the using namespace std statement is causing the ambigous problem. any idea?

when running make in terminal i get following errormessages in terminal:

Any ideas?

Also i am using rasbian on a raspberry pi and Code::blocks IDE

[alexanderkoumis]

You are right. The most recent few commits from @tensaix2j are causing these problems, the project no longer compiles on my machine as well. Most likely 2c03cb22 is the culprit.

[alexanderkoumis]

I am running on a standard x86_64 OSX platform.

[alexanderkoumis]

Looks like @tensaix2j was trying to use the same hack I mentioned above. This is caused by the addition of another to_string function in binacpp_utils.h. Because the new to_string is not in a namespace, and using namespace std is being used, we get this error. I added the std:: prefix to all usages of to_string in binacpp.cpp to avoid using the hack version and it compiled fine.

[pndiaye]

I confirm, prepending std:: to all the calls to to_string does the work, at least on OSX.

[AlconDivino]

when i type std::to_string() no suggestion pops up will it work ?

[AlconDivino]

I now changed everything to std::to_string

Going to console and running make clean and make

Now i get a lot of notes saying parameter passing for argument of type ... will chanfe in GCC 7.1 and at the end failing compilation of libbinacpp.so

Any ideas? i'm pretty deperate rn

[alexanderkoumis]

That’s not an error is it? That looks like a warning. You need to show us the actual error message.

[AlconDivino]

ah now i get it the actual problem is that it doesn't recognize the libcurl.so fileformat.

I guess its because i use rasbian for raspberry pi .

Any idea how i can compile libcurl for my raspberry ?

[pndiaye]

This question doesn't belong in this thread but just for info: You'll probably have to compile openssl (a dependency of libcurl), libcurl, jsoncpp and libwebsockets. You can clone them from their github repo and can definitely find the compilation instructions for your platform there or on other threads more specific to them

[AlconDivino]

So i got another issue but i think this will be too much fpor this thread so i'll open another one

Thank you guys
