wxlua-users Mailing List for wxLua

Hi John,
Could you enable RegisterHotKey and UnregisterHotKey method in wxwindow?
Your comment says "only under WinCE", but it's not correct, as it's
available in Windows and should also be available on OSX with this fix:
http://trac.wxwidgets.org/ticket/12354. Thank you.
Paul.

Hi.
I installed Debian on a tiny pc. Caused by the fact jessie has packages for 
lua, luajit, rockspec and so on, installing a lua environment is a easy and 
quick task. wxWidgets-3.0.2 are available too.
Unzipping wxlua, running cmake and compiling wxlua is easy too. (I wish it 
would be so easy on windows too.)
Anyway there are 2 questions remaining:
- The resulting lua module is named liblua.so instead wx.so. What is the idea 
behind? I renamed libwx.so to wx.so to allow standard cpath to work.
- make generates libwx.so + libwxlua_lua51-wx30gtk2u-2.8.12.3.so
Why is there this libwxlua_lua51-wx30gtk2u-2.8.12.3.so? Is it possible to 
compile libwxlua_lua51-wx30gtk2u-2.8.12.3.so into (lib)wx.so? If not, where is 
a good place to store libwxlua_lua51-wx30gtk2u-2.8.12.3.so? 
TIA
Ulrich Schmidt

@Paul: Thanks for the pointer to ZeroBrane. I looked at your IDE, and it
looks really interesting.
Can you help with some newbie questions?

But I am not familiar with gcc or clang, and what effect they have with
building cross platform apps. Can I not compile to certain platforms with
gcc or clang?
I don't really understand the process here. I am assuming I build my app
and compile it to Win, OSX, IOS or Droid. Do I need to have a 'production'
build for wxWidgets as part of the process?

I am still getting errors after trying new config settings for installing
wxWidgets. Any pointers greatly appreciated.

Hi Roy,
> I am about to install wxWidgets in preparation for wxLua, and looking for any advice or 'gotcha's' before starting the process.
I use my own scripts to get wxwidgets code, run configure and then
call make. I have been doing this for several years with different
versions and the issues were mainly related to compatibility as I
usually compile with the trunk version of wxwidgets and wxlua may lag
a bit behind. I also have several small patches I apply that haven't
been incorporated into wxlua.
> I am looking to build cross-platform Lua based apps
I can't help with this particular issue as I use gcc rather than
clang, but I do build cross-platform lua apps using wxlua and support
Windows, OSX, and various flavors of Linux. I don't know if the
project structure I have works for you, but the repository includes
build scripts for all the platforms (that build wxwidgets and wxlua
from their repo versions) and also allows running the application
without any compilation on all supported platforms. I've seen reports
that some of the users take project files as the skeleton to build
their own apps.
The repository is at https://github.com/pkulchenko/ZeroBraneStudio,
the build scripts are in the build/ folder and the project description
is here: http://studio.zerobrane.com.

I am about to install wxWidgets in preparation for wxLua, and looking for
any advice or 'gotcha's' before starting the process.
I'm a web developer (PHP, HTML5, JQuery) with little knowledge of command
line or the 'configure / make' installation cycle involved, so I ask for
patience.
I am looking to build cross-platform Lua based apps
I am following the install instructions here:
file:///Users/royhinkelman/Downloads/wxLua-2.8.12.3-src/docs/install.html
 1. Installing wxWidgets
 1. re: the example configure file written to produce a Unicode, Debug
 build. I assume I would have a different build for production, correct?
 Are there examples of different build configs for wxWidgets anywhere?
 2. Is the configure example still considered 'best practices' for my
 OS setup?
 2. When I run the example configuration file, I get the following
 warnings. Should I be concerned about any of these?
 1. configure: WARNING: Defaulting to the builtin regex library for
 Unicode build.
 configure: WARNING: system png library not found or too old, will use
 built-in instead
 configure: WARNING: system jpeg library not found, will use built-in
 instead
 configure: WARNING: system tiff library not found, will use built-in
 instead
 configure: WARNING: wxMutex::LockTimeout() will not work
 configure: WARNING: sys/epoll.h not available, wxEpollDispatcher
 disabled
 configure: WARNING: Dialup manager not supported on this platform...
 disabled
 3. when I ran make, I get these.
 1. ../src/osx/webview_webkit.mm:392:30: warning: incompatible pointer
 types sending 'WebViewUIDelegate *' to parameter of type
'id<WKUIDelegate>'
 [-Wincompatible-pointer-types]
 [m_webView setUIDelegate:uiDelegate];

 4. and, when I run cd samples/widgets, make, I get
 1. ld: library not found for -lwx_osx_cocoau_adv-3.0
 clang: error: linker command failed with exit code 1 (use -v to see
 invocation)
 make: *** [widgets] Error 1
 2. and ./widgets says 'No such file or directory'
Any pointers or advise greatly appreciated.
