Re: [ANN] LuaRocks 2.4.1

[Geoff Smith <spammealot1@...>]

hello Hisham

Thanks for the reply. For info, I did download whatever the latest version of LuaRocks was at the time. In fact I think I did this twice over a period of a few months. Both times I got the same problem with a failure to link. (Compile was always OK)

Have any of the Lua maintainers tried the experiment of installing LuaForWindows first and then tried to build a simple LuaRock using any of the MS Visual Studio versions ? I would be really interested to hear what the result of that test was ?

It is disappointing to not be able to use LuaRocks, especially as I am not trying to do anything unusual, just using Win 7, LuaForWindows and MS Visual Studio. All very bog standard stuff

Reagards Geoff

Unfortunately, LuaForWindows includes a version of LuaRocks that is
six years old(!). Is LuaForWindows still being maintained? It seems
so, since there was a release this year at
https://github.com/rjpcomputing/luaforwindows but a number of modules
in it are outdated.

The LuaRocks zip package for Windows includes a Lua 5.1 binary and a
batch installer. However, it is a pure-Lua application, and the
installer accepts flags that allow you to point to the Lua
installation of your choice (e.g. the LfW paths). It also supports
MSVC and MinGW compilers and its installer detects your environment to
make sure it builds binaries compatible with your compiler. Perhaps
your MSVC installation builds libraries that are incompatible with the
LfW binaries?

I think the best way to proceed would be to contact the LuaForWindows
project and ask them to upgrade their LuaRocks installation (and make
sure it is configured so that it works with the rest of their
distribution).
