[SOLVED]HELP! How to make a dll available for Love2D ?

[s-ol]

Try rebuild dll with VS or QT Creator.

His build system isn't the problem, he manages to build working DLLs for standalone Lua. And doesn't QTCreator use the same toolchain anyway (MinGW)?

Maybe you are building The DLL for an incompatible lua version? Löve is Lua 5.1 / Luajit, your "regular" lua might be 5.2.

I build it with lua5.1.4.

http://wiki.qt.io/Mingw:

"There are actually different MinGW toolchains and packages available:

MinGW.org is the original project. The latest version gcc 4.7.2. It only compiles for 32 bit binaries.

MinGW-w64 is a fork with the original aim to also support generation of 64 bit binaries. By now it also supports a much larger part of the Win32 API. The MinGW-w64 project does host several different binary packages, done by different people.

There are binary installers targetting MinGW for both Qt 4 and Qt 5. Up to Qt 4.8.6, Qt 4 ones are built with a MinGW.org toolchain using gcc 4.4. Newer Qt 4.8 binary packages ship with a mingw-w64 based toolchain. For Qt 5, a newer MinGW-w64 toolchain is actually required."
(I mean that MinGW-w64 improves not only 64-bit stuff)

I've thought Code::Blocks is outdated somehow and MinGW too.

@dracula004: Are you sure you need cpp and not plain c for your library?

As same with the luamidi:https://github.com/dwiel/luamidi, it built with g++ 8 years ago,works well in love2d today.

Oh you can use Lua FFI.
Example :

https://github.com/CapsAdmin/goluwa/blo ... s/init.lua

And it works.

thx, I will have a try.

I tried the alien lib for lua. And the same, works well in standalone lua, but crashed in love2d...

here is the project files:

test.7z

(15.6 KiB) Downloaded 100 times

when I run main.lua in love2d, it crashes.
when I run lua_script.lua in standalone lua, it works well.

Can you post the error that is given in the console? Or does LOVE really crash?

Can you post the C/C++ source? That would be really helpful for us to help you.

The source was already attached in former post.

I'm trying to build that dll with vs.

I downloaded the source before (and just now) and there are no c or c++ files in there. Can you post the C/C++ source (not just lua) The .dll file is not really any help.
