[SRC] compile with gcc48, c++11 and optimized flags

Recommended Posts

Welcome to the second part of my guide series. This time I'll tell you how you can compile with gcc48 or even gcc49 like it's the case in vanilla and how you can use c++11 which will allow much more and faster instructions than the old one.

 

At first we need to have a look at our Makefile.

Make sure you edited the Line SVN_VERSION so you won't receive any errors. Try it e. g. to SVN_VERSION = mt2

 

Next, you'll have to declare what compiler you want to use.

Of course you first need to install the compiler, but I guess it's clear (if you haven't done so, just use cd /usr/ports/lang/gcc49 or even 48 and use make install clean).

The line normally say:

CC = g++

This is the standard compiler. You may want to change this line to:

CC = g++49

Or if you're using 48, change it to CC = g++48

 

Now before you compile it, you'd recompile all needed libs with gcc48/gcc49 too! So change the compiler in the makefile and recompile the sources in the following directories:

libgame/src

libpoly

libserverkey

libsql

libthecore/src

 

And then you need to recmopile cryptopp with the newer gcc version too! It's located in the Extern/cryptopp-directory.

 

Now you can compile your game and even your db source with the newer gcc version. You may experience a much smaller file size. The newer compilers will produce an even more faster and smaller gamefile than before.

Oh and if you want to carry out the lib-files you're using on your compiling machine (to make sure everything runs smoothly) you may use the following CFLAG:

 -Wl,-rpath,/usr/local/lib32/metin2

You can change the path to whatever you want! If you specify this, you instruct the linker to use this path so whenever you start your game/dbcache it'll first look in the given directory for the right libs and then, if it can't find the libs there, it'll look elsewhere.

 

 

Using c++11 is a must-have if you want to make new statements. The source code how to load the database without txt-files needs the newer c++ version, so you'll have to upgrade at least the dbcache for it. But you'll experience even more smaller file sizes with this change so it keeps up with more and more advantages.

 

First you may want to specify the new CFLAG. It's called:

 -std=c++11

This tells the compiler to use c++11. Keep in mind that not every compiler can use c++11! The newer gcc version can deal with it without any problems.

If you compile your source then, you may find a new error occuring!

Open every .cpp and .h-file in Notepad++ and do the following things (you can use the mass replacement of Notepad++):

replace typeof with __typeof

replace auto_ptr with unique_ptr

Watch out for the common-directory too!

Then you can recompile the source and it's done!

 

Oh and for this you don't need to compile every other sourcecode with c++11. You can e. g. only compile the dbcache with it.

 

 

Last small hint: You can play with the tuning flags to get even more optimization. -O2 can sometimes be good, but sometimes it's better to use others flags. You can even use -O3 or -Ofast. But be careful with this and consider using -fstrict-aliasing so the compiler won't optimize instructions that'd lead into a crash if it'd optimize them. And always: Pay attention to the warnings your compiler throws at you! They aren't there to just "hang out". They'd lead into crashes, so care about them.

 

Lastly I hope you enjoyed the guide. As in the last one, please tell me if it's good or not and if you have any questions: Feel free to ask.

You can provide more details on c++11 and CFLAG: -Wl,-rpath,/usr/local/lib32/metin2

Okey, beautifull tut, but how can i run core compiled with gcc4.8 and c++11 on freebsd with gcc4.2? Cause instaltion of the newer version failed every time, but on the other works fine.

@Evor

 

pkg install gcc49

 

then after you change all CXX = g++ and CC = g++

 

in

CXX = g++49

CC = g++49

If you want to run the core then just deliver the needed sources. You don't have to install the newer gcc version on your server, you only need the libraries. If you run it, you'll see it ;)

Build with the -static-libstdc++ CFLAG. It will produce a little bigger file size, but i don't think if it's really a problem.

@ATAG:

It's not needed if you use g++. There it's already included. If you declared gcc instead of g++ then you'll need it of course.

Also, do u have solutions for this warnings:

I don't really understand how cryptopp is compileable with g++49, 

 

Tqk5f.png

 

First i changed CXX = g++ to CSS = g++49, didn't work, than I changed all $(CXX) to g++49, also don't work, I don't see at the moment where the compiler in the Makefile from cryptopp is defined. :<

install cryptopp from ports... is really better:

cd /usr/ports/security/cryptopp && make install clean

 

next you need to include in flags /usr/local/include/cryptopp.

 

take this opportunity to say if you use the boost from the ports is better... and avoiding the error "regex" if I'm not mistaken.

/usr/ports/devel/boost-libs/ && make install clean

 

again you need to add in flags: 

  • Inc: /usr/local/include/boost

-> https://wiki.freebsd.org/NewC%2B%2BStack kk

 

Sorry for my bad english.

Greetings!

At first we need to have a look at our Makefile.

Make sure you edited the Line SVN_VERSION so you won't receive any errors. Try it e. g. to SVN_VERSION = mt2

Where are the Makefile?

Here? --> /usr/ports/lang/gcc49

In this makefile... I dont see the Line "SVN_VERSION"
