[wxCode-users] wxEMail compilation problems

[pao_drop <pao...@bl...>]

Hello!
I have downloaded wxEMail-1.0-Beta-2, and I have some difficulties 
compiling it.

I am working on a Windows 7 system, with mingw version gcc 4.7.1.
My version of wxWidget is 2.8.12.

I am compiling with the following command:

mingw32-make -f makefile.gcc WX_DIR=D:\wxW WX_UNICODE=1 WX_DEBUG=0 
WX_SHARED=1 WX_MONOLITHIC=0

Now, I am facing error in the wxPOP3 class. These errors ate linked to 
static initialisation. Here are the compilation messages:

END OF ERROR MESSAGES

Note that I have tested the trick proposed in a post by evstevemd (Sun 
Feb 12, 2012 9:20 pm) on the wxWidgets discussion Forum,
to no avail
Also, commenting off the offensing lines allows compiling wxPOP3 
(presumably in an incorrect way),
but then the compiling stops in wxsmtp.cpp, once again on the static 
initialisation lines,
even if they are now modified according to evstevemd proposal.

So what could I try???
