Porting to FreeBSD - Linker Issues with Lua Libraries

[CoryWalker]

I'm continuing my mission to port EQEMu to FreeBSD. After tackling the std::to_string() and other C++11 issues from a previous thread - as well as fixing some lua and pthread issues - everything compiles (cmake reports 93% progress) and then the linker attempts to create "bin/zone."

The link phase fails. However, there is such an enormous amount of output that I'm not sure where to begin. I get the following output first:

Linking CXX executable ../bin/zone

And then an explosion of error output. Here is a good, representative slice of that error output:

--
CMakeFiles/zone.dir/lua_bit.cpp.o: In function `barg':
/usr/local/build/eqemu/zone/lua_bit.cpp:54: undefined reference to `lua_tonumber(lua_State*, int)'
/usr/local/build/eqemu/zone/lua_bit.cpp:78: undefined reference to `lua_isnumber(lua_State*, int)'
/usr/local/build/eqemu/zone/lua_bit.cpp:79: undefined reference to `luaL_typerror(lua_State*, int, char const*)'
--

Does anyone have a strategy on how to start to troubleshoot this?


The linker command is this:

I had a working build on FreeBSD a few months ago, but I haven't been tracking the changes lately.

Specifically for the LUA, I added fixes like this(below) in a few different places.

I did my work with clang and 9.x I believe.

I'd be interested in any fixes you do resolve.

# include <boost/mpl/next.hpp>
# include <boost/mpl/size.hpp>

+namespace luabind { namespace adl
+{
-class object;
-class argument;
-template <class Base>
-struct table;
+ class object;
+ class argument;
+ template <class Base>
+ struct table;
+
+} // namespace adl
+
+using adl::object;
+using adl::argument;
+using adl::table;
} // namespace luabind

Thanks for your response.

Was your FreeBSD system an x32 or amd64 build?

[jdoran]

When I recently built on Fedora, I had to install an older compatibility version of lua to link. If FreeBSD's Lua is too recent, there might be similar problems.

[CoryWalker]

What is the recommended version of Lua? I am building Lua 5.1 from source using the same compiler.

[KLS]

Lua 5.1 is rec version, when I built on FreeBSD 10 yesterday I did lua51-5.1.5_7 from ports and it worked fine.

Not entirely sure why you're having linker issues.
