Fixed linking wx.dylib with lua library (when building on macOS with …

[valid-ptr]

…external lua library)

[sonoro1234]

Did it work without the fix?

[pkulchenko]

@valid-ptr, I'm not sure why this is needed. I'm building on macOS with an external library and don't see any issues. Here is the cmake command: https://github.com/pkulchenko/ZeroBraneStudio/blob/master/build/build-macosx.sh#L304

[sonoro1234]

I was asking if it worked without the fix because: According to http://lua-users.org/wiki/BuildingModules modules should not link against lualib except for windows.
I could check this is true on linux.

[pkulchenko]

It does work for me on both macOS and linux with the current configuration (without the fix).

[valid-ptr]

This is my configuration (perl):

	my $components="gl;xrc;xml;net;propgrid;richtext;aui;stc;html;adv;core;base";

	system(" cmake".
		   " -DCMAKE_INSTALL_PREFIX=$install_dir".
		   " -DCMAKE_BUILD_TYPE=Release".
		   " -DCMAKE_OSX_DEPLOYMENT_TARGET=$ENV{\"EVI_OSX_SDK_VERSION_MIN\"}".
		   " -DCMAKE_OSX_ARCHITECTURES=\"$ENV{EVI_CMAKE_OSX_ARHCS}\"".
		   " -DwxWidgets_CONFIG_EXECUTABLE=$install_dir/bin/wx-config".
		   " -DwxWidgets_COMPONENTS=\"$components\"".
		   " -DBUILD_VERBOSELY=ON".
		   " -DBUILD_SHARED_LIBS=OFF".
		   " -DwxLua_LUA_LIBRARY_USE_BUILTIN=OFF".
		   " -DwxLua_LUA_LIBRARY_VERSION=5.1".
		   " -DwxLua_LUA_INCLUDE_DIR=$install_dir/include/lua5.1/".
		   " -DwxLua_LUA_LIBRARY=$install_dir/lib/liblua5.1.a".
		   "  $src_dir"
		   ) and die "Can't configure '$libname'";

I think, the reason of linking error is, that static (archive) liblua5.1.a used in my configuration instead of liblua.dylib in your configuration.

PS
Paul, can you check wx.dylib dependencies with "otool -L" on macOS?

[pkulchenko]

I think, the reason of linking error is, that static (archive) liblua5.1.a used in my configuration instead of liblua.dylib in your configuration.

But you do want to reference an external library, right? Or are you trying to build a static executable?

Paul, can you check wx.dylib dependencies with "otool -L" on macOS?

It has a long list of framework libraries (with libSystem, libiconv, libc++, and libobjc), but nothing lua-related.

" -DwxLua_LUA_LIBRARY=$install_dir/lib/liblua5.1.a".

Why don't you want to reference liblua.dylib?

[Oozlum]

I was asking if it worked without the fix because: According to http://lua-users.org/wiki/BuildingModules modules should not link against lualib except for windows.
I could check this is true on linux.

I agree with @sonoro1234. I think you should not link against liblua and rather specify -Wl,-undefined,dynamic_lookup so the library resolves those symbols against the executable at runtime.

ld: symbol(s) not found for architecture x86_64

This suggests that you are mixing 32- and 64-bit libraries. You are compiling a 64-bit library, but if you run file liblua.dylib I suspect you'll find it is 32-bit.

@valid-ptr, closing this one, as I don't see this as an issue. Feel free to re-open if you have any new information.
