Re: LuaBitOp: Cant require "bit=>./bit.so: undefined symbol: luaopen_bit

[Bezobiuk Volodymyr <dedoogun@...>]

Hi,

at first, check if the environment are read by the interpreter, by adding this debug output before  'require "bit"':

print("LUA_PATH =", os.getenv"LUA_PATH")
print("LUA_CPATH =", os.getenv"LUA_CPATH")

is it does print nils or either print some values other than you expected investigate why environment are broken

also, check package.path variable - it should be the same as your LUA_PATH env var


Sincerely,
  Volodymyr

Hi,

I am trying to get LuaBitOp to work.
On a GENTOO Linux system (AMD64), which is updated and maintained on a
daily base, I did a

    make

and

    make install

, which works fine and installs bit.so into

    /usr/local/lib64/lua/5.1/bit.so

.

In the enviroment this is defined:

LUA_PATH=/usr/lib64/lua/luarocks/share/lua/5.1//?.lua;/usr/lib64/lua/luarocks/share/lua/5.1//?/init.lua;/usr/share/lua/5.1//?.lua;/usr/share/lua/5.1//?/init.lua;/usr/lib64/lua/luarocks/share/lua/5.1/?.lua;/usr/lib64/lua/luarocks/share/lua/5.1/?/init.lua;/usr/share/lua/5.1/?.lua;/usr/share/lua/5.1/?/init.lua;./?.lua;/usr/local/share/lua/5.1/?.lua;/usr/local/share/lua/5.1/?/init.lua;/usr/local/lib/lua/5.1/?.lua;/usr/local/lib/lua/5.1/?/init.lua;/usr/share/lua/5.1/?.lua;/usr/share/lua/5.1/?/init.lua

A script containing 'require "bit"' leads to this:


    lua: error loading module 'bit' from file './bit.so':
        ./bit.so: undefined symbol: luaopen_bit
    stack traceback:
        [C]: ?
        [C]: in function 'require'
        bittest.lua:3: in main chunk
        [C]: ?
    make: *** [test] Error 1


What did I wrong? How can I fix this?

Thank you very much in advance for any help!
Best regards,
