As far as I know it is not unsigned char.
After removing inicialization I get

Hi John,
As far as I understand, wxstedit is only needed when wxlua is compiled
with wxwidgets 2.8.12; it's no longer required for 2.9.x. Or am I
mistaken?
If it's not needed for 2.9.x, then "svn checkout --ignore-externals"
can probably be used to skip it (I can't test it at the moment).
Paul.

I don't have any time today, but I remember seeing something about
"braces ... scaler initializer" on the Lua mailing list after the
release of 5.2.
I see that on that line I am trying to properly initialize a lua_Debug
struct, probably the struct has changed since 5.1? You can rem that
line out for now...
lua_Debug luaDebug = INIT_LUA_DEBUG;

I will change the svn:externals to use http and not https... sigh. You
may have to delete wxLua/modules/wxstedit and recheckout.

Is this for wxstedit? The external in wxLua/modules? Try deleting the
wxLua/modules/wxstedit dir and update again.
Sourceforge changed their repo address for their new "platform" and
wxCode updated to to, but wxLua has not yet.
http://sourceforge.net/apps/trac/sourceforge/wiki/Subversion#Access
The claim is that "No username and password will be requested when
performing read operations."
Is this not true?
I will try to delete my stored passwords and try as a "normal" user.

I have that version already. Unfortunately it doesnt help.
So if
anybody kept older versions it would be great if he can share.

I don't think I have copy of a binary that old anymore, but there is a

Hey, 
I need wxLua Binary versions from 2004/2005. Reason I need
it is that for a specific tool we wrote which seems to have problems
with newer wxLua versions.

Thank you for checking... Good to hear that it's working for you. I
suspected that something could be wrong with the way I'm building it,
but all my other tests (and the entire application) are working
without issues. I'm building lua with the same command; although I
used a copy from one of the previous builds, but none of the lua
settings have changed. I'll do some further testing, but so far my
builds still show the same issue.
Paul.

Check that wxpng-* library should not be linked into wx.so. I did read
the documentation, but I missed a warning in the ./configure output
that indicated that "system png library will not be used without
system zlib" and as the result wxwidgets was using system png library,
so I was fighting against that.
Thank you John for clarifying this. I'm rebuilding with (more)
appropriate settings...
Paul.

Well, I'm not sure there is much difference between what is happening
and what you're asking to happen by calling assert(), which is to
terminate the program violently. But, in any case, I don't get the
same result so I suspect something is wrong with your build. I would
review your build and clean and rebuild it after sorting out any
inconsistencies with multiple png libs or anything else like that.
I just tried the program "test.lua" using the lastest wxLua SVN using
wxLua's provided Lua5.1 in CentOS 6. (I just noticed that you have to
do "mv libwx.so wx.so", I will fix that)
-- ------------------------------------------------------
-- test.lua
local wx = require("wx")
--os.exit()
--assert(false)
--return
print("hello")
-- ------------------------------------------------------
Note that I'm in the build-2.9-wx_gtk2/lib/Debug dir and run $gdb
../../bin/Debug/lua. That could also be a problem, are you building
using one version/build of Lua then running with a different one?

wxLua does not have switches "--with-libpng" are you talking about
building the wxWidgets library?

Yes, it nearly always is best to use the system libraries for such
basic libs (zlib, png, tiff, jpeg, and gtk).
Reread that thread, it explains exactly what your problem is and how
to fix it by using the system libs. Hint: don't specify --with-libpng
at all and last few lines of the output of configure tells you what
will be used. Don't forget to clean or preferably delete the old
wxWidgets build dir to be sure that you're getting what you think
you're getting.

wxLua links to whatever libraries that wxWidgets was linked to. Please
see the docs below and run the appropriate "wx-config" command to
understand how your wxWidgets libs were built and where the values in
wxWidgets_LIBRARIES come from.
http://wxlua.sourceforge.net/docs/install.html#C2.5
As I have mentioned before and as people on the Lua mailing explained
recently (though not definitively enough) you cannot just link
together random versions or builds of libraries together. For example,
if you want to use the system png library then everything your app
(wx.so) links to must have been built against that same lib. It is a
recipe for disaster to try mix versions. It may work, but you should
have no expectation that it should or will the next time you build it.
The problem with using another random version/build of a png lib (for
example) on Linux is that GTK will definitely be linked to the sys
version and GTK cannot be easily (or maybe ever) be linked to
staticly.

Hi John,
I'm using assert() to check some of the conditions in my code before I
start the event loop and noticed that when the script exits after
"require 'wx'", but before the main loop is started, it triggers
segfault on Linux (tested on Fedora 18, but I saw the same thing on
Ubuntu).
The script is as simple as one line with require 'wx'. Adding one more
line causes various segfaults that all seem to be originating from
wxLuaStateRefData::CloseLuaState; the results are shown below. I'd
appreciate any insight into what may be causing this or how to fix it.
Thank you.
Paul.

Hi John,
I ended up patching the makefile
(luamodule/CMakeFiles/wxLuaModules.dir/link.txt), but would prefer
something a bit more robust.

Hi John,
I ran into an issue with configuring wxlua to use system libpng
library. I tried both --with-libpng=builtin and --with-libpng=sys, but
I get exactly the same result.
This discussion
(https://groups.google.com/forum/?fromgroups=#!topic/wx-users/2QWQD0qUVUc)
indicates that it's better to use a system library, but I can't
configure wxlua to *not* link builtin library as can be see from this
output from cmake:
-- * - wxWidgets_LIBRARIES =

wxlua should somehow check if the library is configured as "builtin"
or "sys", but for now I just need to check if this is going to work
for me, so, I'm fine with modifying it manually. I need to exclude
libpng as it creates problems with systems libraries required by GTK
on Linux.
What is the way for me to tell wxlua *not* to include wxpng-2.9? Thank you.
Paul.

It'll definitely be no slower than using a wxDirTraverser since you
won't have the overhead of extra calls to the traverser itself.
Directory reading is already slow enough and I couldn't see the use of
the traverser in Lua since it's far more flexible than C++ code.

Hi John,
Thank you for the link to Traverse implementation; I should have
looked there myself. VZ uses GetFirst and GetNext, whereas I actually
use FindFirst and FindNext. I'm not sure what exactly the differences
are, but I'll re-implement Traverse in Lua and see if it is
sufficiently fast for my needs.

Hi John,
I do that now (I use GetFirst() and GetNext()), but it's a bit slow
for my purposes. GetAllFiles is much faster, but my main problem with
it is that I can't exclude directories I don't need (for example,
.git, .svn and others), and those can be quite slow to scan (due to a
large number of directories and files).
For example, when I try GetAllFiles it scans a folder with 278 files
(including subfolders, most of these are in .git folder), it takes
0.8s to scan (and subsequent runs only take 0.08s or so). Same folder
without .git subfolder takes only 3ms or so to scan (17 files).
I'm hoping that the Traverse method would give me a way to do it fast,
but also allow me to filter out those folders I don't need.
Unfortunately I can't test it without having access to it.
Paul.

Please use GetAllFiles() or roll your own GetFirst() GetNext()
recursive function instead.
http://wxlua.sourceforge.net/docs/wxluaref.html#wxDir
An example of how to do that is here, see wxDir::Traverse()
http://svn.wxwidgets.org/viewvc/wx/wxWidgets/trunk/src/common/dircmn.cpp?view=markup
I don't really see any gain in using it for Lua programs as it just
adds a layer of complexity and without enumeration type-safety can
cause more problems than it would solve.

Hi John,
I noticed that wxlua is missing the Traverse method in wxDir object
(http://docs.wxwidgets.org/2.8/wx_wxdir.html#wxdirtraverse).
Is it possible to add it or is there something more fundamental that
prevents it? I'd also like to make sure that wxDirTraverser
(http://docs.wxwidgets.org/2.8/wx_wxdirtraverser.html#wxdirtraverser)
will work as it's required for Traverse to be useful. Thank you!
Paul.

Summary: wxLuaFreeze.exe command line problem
Initial Comment:
Good day!
 
It seems that script files which path includes national symbols can not run under wxLuaFreeze.exe
May be wxLuaFreeze.exe converts argument to UTF and then trying to find nonexistent location.
 
Is there necessary to convert argument to UTF?
 
Thanx.
