Compiling Error w/ TMP4 Source

[batlig 0]

 

Hello,

Source : [40250] Reference Serverfile + Client + Src [15 Available Languages] by TMP4

I've deployed FreeBSD-13.3-RELEASE-i386 on VPS. I've downloded the server and run it. Me and my friends can join the server and play, there is no problem with that. But I can't build the game source. Server is 32-Bit, I've installed the provided pkgs.

 

Here is the some errors:

I didnt know if i should change it or not bu, i've decided to change all 'unary_function' to '__unary_function'

 

Then i got this error while compiling :

linking ../game....
Moving ../game to /usr/metin2/server/share/bin
All done! Your game file moved to your server directory.

 

and also changed it and then i was able to compile the game successfully. i've restarted the server and I was able to join and play. Should I also change the client source? i don't know if it brings any problem/bug/errors?

 

I'd love to hear your opinions.

Which C++ version are you using? std::unary_function and std::binary_function were removed in C++ 17.

so no problem with changing "unary_function" to "__unary_function" ?

 

thank you for your response.

I meant the version of the C++ standard you set in the compiler (valid versions should be C++ 98, C++ 11, C++ 14, C++ 17, C++ 20, C++23 and C++26). If you are using C++ 17 or higher then std::unary_function (and friends) won't be available.

I don't know how (or why) you are using std::unary_function (and its friends), but you don't need it. You can use functors, lambdas, std::function or std::bind.

I don't know either.. Like i said before, it is [40250] Reference Serverfile + Client + Src [15 Available Languages] by TMP4 files. I did not even edit anything in the code. This is the file (src/common/stl.h)

The problem isn't the source files, it's how you configured your C++ compiler.

You have to set the C++ version to 11 or 14, because as I said, std::unary_function was removed in C++ 17.

Again, you don't need to change anything in the compiler because you can replace std::unary_function with one of the modern alternatives I gave.

Ohhh, OK. Thank you so much for your help. Have great day..

how did u changed c++ version?
