[wxlua-users] Some feedback

[Ulrich S. <u.s...@gm...>]

Hi all.

I compiled wxlua (trunk)  using MinGW-64 gcc 4.8.1 on Win7 to get some 
32bit Windows exes/dlls.
I compiled against wxwidgets 2.8.12 and 2.9.5
I figured out some nessesary changes: (2.8.12 works. 2.9.5 not finished yet)

1. alredy discussed in this mailing list: modules/wxbind/src/wxcore_bind.cpp
     The 2 "#if defined(__MINGW32__) || defined(__GNUWIN32__)" at line 
66 and 7553
     create a error and i removed the entire if-endif-blocks. It seems 
newer gcc compilers
     dont need this hack anymore.

2. modules/wxbind/src/wxbase_bind.cpp
     2 constants not declared (in 2.9.5) -> inserted 3 #if defined()'s 
below line 387
--8X--------------------------------------------------------------------------
#if wxUSE_FSWATCHER && wxCHECK_VERSION(2,9,4)
         { "wxFSW_EVENT_WARNING", wxFSW_EVENT_WARNING },
     #if defined(wxFSW_WARNING_GENERAL)
         { "wxFSW_WARNING_GENERAL", wxFSW_WARNING_GENERAL },
     #endif
     #if defined(wxFSW_WARNING_NONE)
         { "wxFSW_WARNING_NONE", wxFSW_WARNING_NONE },
     #endif
     #if defined(wxFSW_WARNING_OVERFLOW)
         { "wxFSW_WARNING_OVERFLOW", wxFSW_WARNING_OVERFLOW },
     #endif
#endif // wxUSE_FSWATCHER && wxCHECK_VERSION(2,9,4)
--8X--------------------------------------------------------------------------

3. I linked a existing lua51.dll (luajit) and used the luajit header 
files to include.
     modules/wxlua/lbitlib.c: need a definition for LUAI_INT32, so i 
inserted at line 44:
--8X--------------------------------------------------------------------------
#if !defined(LUAI_INT32)
   #define LUAI_INT32    int
#endif
--8X--------------------------------------------------------------------------
(probably not bullet proof but at least it worked.)

4. Suggestion: I compiled MinSizeRel. I need to strip manually.
     May be you can strip dll and exe files automatically for Release- 
and MinSizeRel-builds?

TIA.
Ulrich.

Why are you not using a 3.x wxWidgets version? It should be better and
wxLua compiles against it.

Thanks for the reminder. What mingw are you using? It looks like things
have changed since I last installed it.

One of these?

Humm, this should be fixed in SVN, but maybe I forgot to commit it.

I'll probably leave this as an exercise for the user since there may be
some value in the non-stripped binaries.

Thanks for the feedback, I hope to get to these next week.

I wasnt shure wxlua compiles with wxwidgets 3.x.

I use MinGW-64 (http://sourceforge.net/projects/mingw-w64/) gcc4.8.1

It is not possible, Lua needs a shared library for require() to load.
However, you can use wxLua.exe or wxLuaFreeze.exe to have a single
executable that does the same thing as calling 'require("wx")' without the
extra wx.dll lib since it's embedded in the exe.

Sorry John, thats not correct. It is possible (and i do it this way with 
other lua libs + lua runtime) to compile a static lib.
The only exported function needs to be luaopen_<modname>. So it would be 
great if i could build a single wx.a exporting luapoen_wx.

I tried to write my own makefile but until now it was too time consuming 
to figure out the dependecies. So if you could tell me the dependencies 
needed for wx.dll, i probably could write the needed makefile by myself.

TIA.
Ulrich.

I compiled sucessfully wx.dll using wxWidgets 3.0 (mingw64/gcc4.8.1).
So far so good.
Now i want to compile the wx-lua-module as a static lib. Is this 
possible using cmake? I got a libwx.dll.a but this points to wx.dll and 
thats not what i want.

TIA.
Ulrich.
