Unable to make a gun on osx yosemite. Undefined characters

Question

I try to make gunplot 5.0.0 under osx yosemite (10.10.4) and it comes up with errors:

Something seems to be related to lua. This is my lua env:

 $ lua -v Lua 5.3.0 Copyright (C) 1994-2015 Lua.org, PUC-Rio 

I do not understand the output, please help!

Answer 1

It looks like the module / application you are compiling is not Lua 5.3-compatible . It uses luaL_checkint , but Lua 5.3 uses luaL_checkinteger . You need to update the module or use the compatibility switch LUA_COMPAT_APIINTCASTS ( LUA_COMPAT_5_2 should work just like it does LUA_COMPAT_APIINTCASTS ).

Answer 2

I had the same problem when using macports and trying to compile gnuplot (as a dependency for latex2rtf). In the end, the fix was relatively simple ...

In the version of gnuplot I need (gnuplot-5.0.1), there are two links to luaL_checkint in the lua.trm file found in the term folder:

 ./term/lua.trm: t_num = luaL_checkint(L, 1); ./term/lua.trm: t_num = luaL_checkint(L, 1); ./term/lua.trm: token_cnt = luaL_checkinteger(L, 1); 

Changing luaL_checkint to luaL_checkinteger did the trick. See Paul Kulchenko's answer for this compatibility issue.
