Wrong architecture error when loading lgi

I have Lua 5.3 installed on my Mac Sierra OS with Luarocks and it seems to be working fine. In fact, I have lgi installed and this file works without error from the terminal when I run it:

local lgi = require'lgi'

However, in ZeroBrane with the 5.3 interpreter selected, the same file produces the following error:

/ZeroBraneStudio/bin/lua.app/Contents/MacOS/lua53: error loading module 'lgi.corelgilua51' from file '/usr/local/lib/lua/5.3/lgi/corelgilua51.so':

I also tried using the installed interpreter:

path.lua = "/usr/local/bin/lua"

but this had no effect.

SO... does anyone have any pointers? Why does the terminal work but ZeroBrane complain about the wrong architecture?

Solution

  • lua53 binary that comes with ZeroBrane Studio is i386 executable (32bit), but the library you are using is probably 64bit, hence the message about the wrong architecture.

    path.lua = "/usr/local/bin/lua"

    but this had no effect.

    If you are using it with Lua 5.3 interpreter, you'll need to set path.lua53 instead; try path.lua53 = "/usr/local/bin/lua" (assuming /usr/local/bin/lua is Lua 5.3 interpreter). See Interpreter Path section in the documentation for details/examples.

    Also, this filename (/usr/local/lib/lua/5.3/lgi/corelgilua51.so) looks suspicious, as it mixes 5.3 and 51, but if it works from the command line, it should work from the IDE as well when you set path.lua53.
