Cannot require LuaCOM v.1.4 with Lua v.5.3.5

[RostislavDmKudryashov]

I use Windows 8.1 and Visual C++ 2015. Everithing works fine with Lua v.5.1.5. I built LuaCOM for Lua v.5.3.5 in the same way, but using macro NLUA51. Everything comiled and linked successfully. But after require ("luacom") I got the message [string "luacom5.lua"]:9: assertion failed! This message is issued by the file luacom5.loh invoked in the function luacom_open in the file luacom.cpp. I converted luacom5.lua to luacom5.loh using program bin2c.lua. The LuaCOM distribute is downloaded from https://github.com/davidm/luacom

Does anyone know how to build correct luacom.dll 64 bit or where it can be downloaded from?

You also have to rebuild luacom5.loh. This file also depends on Lua version

[RostislavDmKudryashov]

If you looked at the file luacom5.lua - the source code for the luacom5.loh - you would see that the line #9 is the first executed and contains the statement: assert(luacom) It is the line that generates the error. But this line does not depend on the Lua version in any way!

Not to mention that I actually rebuilt this file. You just didn't read the 7th line of my original message. The conversion (rebuilding) was done using the command lua53.exe bin2c.lua luacom5.lua > luacom5.loh

[moteus]

I only can suggest trying my fork which works with Lua 5.3 I remembering that I export luacom to the global namespace.

Really? I think luacom5.loh is compiled to bytecode, therefore its not compatible between versions and has to be rebuilt.

A thousand thanks to moteus! Your distribute https://github.com/moteus/luacom is OK. To compile luacom.cpp from the command line I had to replace LUACOM_DLL with "luacom.dll".

Can anyone provide a 64-bit luacom.dll for download? Or do I have to build it myself from https://github.com/moteus/luacom? If so, can you/anyone confirm that is for a 64-bit version of the dll and that it is fully working. I don't really want to have to install VS 2010 (already gave 2015, 2017, 2019 and 2022 installed...!) to build this but I will if there is no other way. Seems to be a reasonably common request for the 64-bit version, and I am surprised that someone hasn't made the binary directly available....

Thanks!
