[Wxlua-users] bakefile & /NODEFAULTLIB problem

[Francesco M. <f18...@ya...>]

Hi,
    I've grepped all my wxLua (and wxArt2d) updated CVS repositories and 
I did find only one occurrence of the "/NODEFAULTLIB" string:

in app_wxlua, Win32 debug:

# ADD LINK32 /VERBOSE:LIB /NODEFAULTLIB:MSVCRT.lib wxluadebug.lib 
wxluasocket.lib wxlua.lib

is it right ? or I'm missing some other occurrences ?
Also, is someone so kind to explain me (maybe just quoting the text from 
other mails) why that setting is so dangerous ?

Thanks a lot,
Francesco

It's actually necessary so that the wxLua app doesn't immediately
crash when run in VC 2003 (at least). I don't really understand it all
that well. This fixes some problem with the compiler's debug vs.
nondebug libs being linked with incorrectly.

Hi Francesco,

I think the problem might be related to the fact that lua is a non 
windows/wxWidgets application ( plain C ).
As i said Cmake does not have the switch in wxLua, and also i can debug 
into Lua itself, which is a problem on bakefile. Maybe you can compare 
the two, to see where things go different.
Not having the switch in bakefile, makes application crash at the first 
stages of initialization, and people told me the warning  is not to be 
ignored.

yes, that could be.

I think this is related to something else: that setting should be used 
only with app_wxlua not with wxlua library...
did you tried to use WX_DEBUG=1 from command line when compiling wxLua ?
It should set all debug info on...

I'll do.

that is strange, right. But for "application" you mean only wxLua 
application (wxlua/apps/wxlua), right  ?

I am talking lua not wxLua. So wxLua library i can debug, but in the 
underlying lua code i can not.
I used project files, and in there the debug config, so all is set right.
I still thing this not being able to debug into the lua library is 
related to the switch.
 
Try it in app_wxLua, and put a break inside lua code.

Any application, like teto in wxArt2d too.
apps/wxLua  for instance crashed when removing the switch in question.

Some People say that normally this switch tells us that something is not 
set up right.
And with Cmake it becomes clear it can be done somehow, but i do not 
know where the problem is exactly.

ops; probably I understood the problem.
I'll soon (as soon as I fix other compilation problems under linux) do a 
commit which will fix this.

as soon as linux version compiles, installs and uninstalls correctly, 
I'll begin win32 testing.

ok, hopefully my last changes should have fixed this removing that switch.
