Hi Ben,

I'm using wxWidgets as a static library (until today I used Phil's XCode
project for building static unicode library)

Today I built it using terminal make files. (../configure
--enable-monolithic --disable-shared --enable-unicode
--enable-postscript --enable-debug-flag --enable-precomp-headers), and
now I'm using wx_macud-2.6.a library and try see if this will help.


Let us know how you get on.


Due the fact that we are making a custom build on wxWidgets I think it
is better to use static library.

Also in the INSTALL-MAC.txt I found the following:
"Note that while using this method is okay for development, it is not recommended that you
require endusers to install wxWidgets into their system directories in order to use your program.
 One way to avoid this is to configure wxWidgets with --disable-shared."


I agree. For development purposes (I call this XCode-personal) dynamic
linking is a definite plus, it is a step towards zerolink.

Since we will be embedding the libraries for the deliverable, we
should choose on the basis of whether you prefer/have more experience
with embedding dynamic or static libraries, no?

I meant to add that if you want me to understand the problems you are
facing, you ought to post the exact steps needed to observe them, as I
will probably have to start afresh.
