Hmm, are you saying you used the compiler option in VC /zp 1 when
compiling? If so, you are not going to have a lot of fun with this.
Basically you will have to wrap all wxWidget's includes with the following:
#pragma push
#pragma pack(4)
#include "wx.h"
#pragma pop
That "should" take care of telling your code that all of wx is
default 4 byte aligned and then return you to your 1 byte alignment. Of
course if you add any includes from your library you need to reverse it:
#pragma push
#pragma pack(1)
#include "blargo.h"
#pragma pop
Please note also that there are some annoying bugs which crop up due
to pack settings which are hard to avoid. I don't know about VC7+ in this
area but previously changing the packing settings caused some very serious
problems for me in the past. Someone had written a library with /zp 1 set
because it made all their code really tiny but even after modifications such
as the above, some code generated improper offsets randomly.
I "hope" I've misunderstood your question here as using /zp 1 is a
really bad thing to be doing in most cases..
