Help compiling on windows

[rayaman]

I used the rockspec to compile the code, but this was the error message I got:

I also tried with visual studio 2005 cmd and still got an error, a slightly different one though:

Setting environment for using Microsoft Visual Studio 2005 x86 tools.

Any help would be very much appreciated

Thanks for the report. I will try to look into it. I only built on Windows with Mingw gcc, not with Microsoft VS. So, in supported_platforms = {"unix", "windows"} in the rockspec, the "windows" bit may be a bit too ambitious... :(

MSC requires a few 'hacks'

[philanc]

Issues I found were mostly with array dimensioned with a variable.
variable-sized arrays have been introduced with C99. Not supported in C89 ...and in VC (even VC 2014!)

I fixed what I could (luazen.c, base58.c). Could you please test building the last luazen version and let me know if works for you?

Hey thanks for your reply and sorry for the really late response. I re-ran the install command and still got the error:

For now I will continue using linux for my tests.
