Apparently this rock is not available using luarocks. Or is there a way to add this?

minoki commented 6 years ago

I finally uploaded this to LuaRocks: https://luarocks.org/modules/minoki/luaexif

Please try luarocks install luaexif. You may need to set LIBEXIF_DIR variable.

Thanks!

I successfully installed the rock:

nicolasfranck:~ njfranck$ luarocks install luaexif

luaexif 1.0-1 is now installed in /usr/local/opt/openresty/luajit (license: MIT)

Although loading is problem:

require "luarocks.loader"
local exif = require("exif")

returns:

nicolasfranck:lua njfranck$ luajit exif.lua 
luajit: ./exif.lua:2: loop or previous error loading module 'exif'
stack traceback:

Not sure what is wrong. The file exif.so seems to point to libexif.so:

nicolasfranck:5.1 njfranck$ otool -L /usr/local/opt/openresty/luajit/lib/lua/5.1/exif.so 
/usr/local/opt/openresty/luajit/lib/lua/5.1/exif.so:

    /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1252.0.0)

Your filename exif.lua seems to confilct with the module name. Try a different name.

Right ;-)

But now I got this error:

According to documentation found around the web, this should be caused by conflicting lua versions, but the luarocks and luajit seem to be the same version?

I am getting a similar error too. 

luajit dumpexif.lua

Can you tell me how to fix this?

@nicolasfranck I've uploaded a new version (1.1) to improve compatibility with LuaJIT. Please try it out.

@romanb089 It appears that you built luaexif with Lua 5.4 headers but using with LuaJIT (which is compatible with Lua 5.1, not Lua 5.4). Please try re-building with LuaJIT header.

Thank you very much! New version 1.1 solved my problem
