Find a 64 bit Lua static library liblua.a

Postby htm_hx » Jul 06, 2017 14:44

Ask God friend to help younger brother to generate a 64 bit Lua static library liblua.a
Yes, it's 64
Thanks a million!
Little brother can't make 64 liblua.a

do you have msys2 installed?
if so all you need to do is launch the 64-bit shell, cd to the lua-5.3.4 directory and: make mingw
I don't have other mingw versions installed, so this is all I can help.
you can find msys2 at http://www.msys2.org

Lua provides compiled binaries for different OS's (for WIN64, static, see below)
64 bit static Lib (for Windows), download
There is no need, to build it oneself, from source ...
Current name: liblua53.a (version: 5.3.4)

Thank you very much for your help. Thanks again for the big brother

You could test your Lua library with this little curve sketcher.
Some roots are written to the console.
Type in an expression at the prompt.
Then set a range on the x axis e.g, -9,9
It's maybe a bit buggy, I just pieced it together.
The available functions are Standard Lua(seen in the code)

Code: Select all

#include "crt.bi"
#Include Once "Lua/lauxlib.bi"
#Include Once "Lua/lualib.bi"
