  • Platform:

    • Windows

  • LuaRocks version:

    • 3.9.2

  • LuaRocks output from when the issue occurred:

mingw32-gcc -shared -o mime/core.dll src/mime.o src/compat.o C:\Program Files (x86)\Luarocks/lua5.1.lib -lMSCVCR80
  • Description:
    • This is the line that causes an error. The problem is with the include of the MSVCR80 lib, being a dll in windows. Instead of -lMSVCR80, it should be C:\Program Files (x86)\Luarocks/MSVCR80.dll. I tested it by changing the line extras[#extras+1] = "-l" .. (variables.MSVCRT or "m") to extras[#extras+1] = dir.path(variables.LUA_LIBDIR, (variables.MSVCRT or "m")) .. ".dll" in the builtin.lua script.
      Maybe this is not the most appropriate way to do it (especially the addition of ".dll" at the end), but it is just to give an example :)

@RedNeath thanks for reporting. A few questions:

  1. did you install with install.bat or are you using luarocks.exe? I assume it was install.bat.
  2. what is the exact linkage error messages you are getting?
  3. What happens if you run luarocks config variables.MSVCRT m? Does it make compilation work?
  4. which flags did you use on install.bat? If possible, could you please run it again and paste the full output of execution here? It would be useful to know if you get any warnings.

I currently don't have a Windows machine to try these things myself, so help debugging Windows issues is greatly appreciated!

No problem! :D

Just to point a few things out, because I'm not sure I have been explicit enough in my first comment: the abovementionned error doesn't come when installing luarocks, but when installing packages (or "rocks" I believe).
Also, note that solving this problem will not allow me to install any package anyway, because I installed Lua with the luarocks distribution (/L option), which installs a x86 version, and my c compiler is an arm compiler, as is the CPU of my device. I could compile and install lua on my own, but since my computer is not very powerful, and I am trying to create a RESTful API with pegasus.lua, I decided to use my IDE code transfer option to actually develop on a remote VPS.

  1. (& 4) I installed Luarocks using the install.bat script in an elevated powershell. Here is the full installation trace (including the command at the top).
C:\Users\Xiaomi\Downloads\luarocks-3.9.2-win32\luarocks-3.9.2-win32>.\install.bat /L

Try compiling lua yourself, and in your luarocks config make it link with ucrt instead of msvcrt, I have had no issues after doing that

Try compiling lua yourself, and in your luarocks config make it link with ucrt instead of msvcrt, I have had no issues after doing that

You're probably right. Sorry I didn't check that earlier but it seems I was wrong since the very beginning. From what I've seen, the mingw32 compiler actually uses the -L and -l options to link libraries, which means the command is probably correct.

I didn't take a look at how the installed compiler is detected (or if it even just is), but the one I use is the msys clang arm compiler (as shown by the trace below).

PS C:\Users\Xiaomi> where.exe gcc.exe
C:\msys64\clangarm64\bin\gcc.exe

PS C:\Users\Xiaomi> gcc --version
clang version 17.0.6
Target: aarch64-w64-windows-gnu
Thread model: posix
InstalledDir: C:/msys64/clangarm64/bin

I'll try to install Lua and Luarocks using this compiler someday and detail the installation procedure to make both run properly on an ARM 👍

I created this tutorial which should also work on ARM, if you replace the parts where I delete the ARM bits with deleting the x86_64 bits
