Compiling c++ Scripts

[Joethlon]

All right, as a coding noob, I've been trying for hours to compile these scripts (here (https://www.vaultmp.com/showwiki.php?title=Saving+items+of+players) & here (https://www.vaultmp.com/showwiki.php?title=Saving+position+of+players)). I've been using Visual Studio 2010 and I can't for the life of me figure out how to compile these as the necessary .dll/shared object files. Trawling through google yielded no results - that I could understand at least - and as a result I'm wondering if any of you could help me?

vaultmp scripts require a C++11 compiler. I don't know how much of C++11 is already implemented in VC++. You probably need the most recent version (Visual Studio 2012).

https://www.cpprocks.com/a-comparison-of-c11-language-support-in-vs2012-g-4-7-and-clang-3-1/

I see at least three C++11 features which are lacking in VC++ but required by vaultmp. So you either have to wait for Microsoft to release an updated version of the compiler or use GCC 4.7.1 (MinGW when on Windows) or Clang.

I'm using GCC. My recommendation is to install Code::Blocks, then overwriting MinGW with this version:

https://sourceforge.net/projects/mingwbuilds/files/windows-host/4.7.1/release/

EDIT: After messing around with it a bit I found that adding '-std=gnu++0x -U__STRICT_ANSI__' to 'other options' in the compiler settings fixes the below problem, I get a 'lib(projectname).dll' file when I compile yet I still get these two errors:



obj\Release\itemsave.o:itemsave.cpp:(.text+0x2d0): multiple definition of `OnPlayerDisconnect'
obj\Release\positionsave.o:positionsave.cpp:(.text +0x1a0): first defined here


Also the vaultserver says it can not find the script.



I've overwritten MinGW with that version and started a .dll project in Code::Blocks which I added the two scripts two as a .cpp source along with the vaultscript.h. Now I must be doing something horribly wrong but when I go 'Build << Build' it returns with numerous errors, most notably this file appears in the window:

You can define a callback only once per script; either merge the contents of both scripts and their callbacks into one compilation unit by hand, or compile both scripts separately (into two object files).

Thanks for the help so far Recycler, been great :), I compiled the .dll's flawlessly but now it's showing a 'could not load' error in the vaultserver.

Did you compile as static library? (append -static to linker options)

Else you need the GCC dynamic libraries installed on your Windows machine:

libstdc++-6.dll
libwinpthread-1.dll
libgcc_s_sjlj-1.dll

(those DLLs are in your MinGW files somewhere, but need to be copied into Windows/ or to vaultserver exectuable place)

[Joethlon]

Not sure how to go about giving you those things, but here's a mediafire link for the Code::Blocks projects. https://www.mediafire.com/?6y619chk0smq84b

Compile as static library:

(then Rebuild)

Or copy the DLLs as stated above.

[Joethlon]

Still getting the same error after trying both suggestions :L

[foxtacles]

I compiled your scripts and they work for me. They should be about ~160kb in size if you linked statically.

[Joethlon]

Both scripts compile to either 182Kb or 183Kb, could it be that this is not set up properly?

I had the same error until I installed this compiler
