wx-2.9.5 problem

[Igor Korot]

Hi, ALL,
I successfully built wxWidgets-2.9.5 with following configuration:

../configure --enable-stl --enable-std_containers
--enable-std_string_conv_in_wxstring

My system is Gentoo Linux and I just upgraded my compiler to 4.7:

***@IgorReinCloud ~/elance5/BaseballDraft/build $ gcc --version
gcc (Gentoo 4.7.3-r1 p1.4, pie-0.5.5) 4.7.3
Copyright (C) 2012 Free Software Foundation, Inc.
This is free software; see the source for copying conditions. There is NO

Now trying to compile my own code I'm getting errors:

error: cannot convert 'const wxString' to 'const char*' for argument '1'

On Windows and Mac/Cocoa with 10.6 as minimum everything built fine.

What am I missing?

Thank you.

That --enable-stl (your other configure options are redundant with it BTW)
disables implicit conversions of wxString to const char* or wchar_t* as it
enables implicit conversions to std::[w]string and you can't have both.

So you need to be explicit about your conversions if you want your code to
compile with this build.

So what is the purpose of this option?
Backward compatibility?

So if I build without it everything will compile?

Thank you.
