[Achim Breunig 2003/07/27 00:35] Yes, now I tried this without success.

[Achim Breunig 2003/07/27 00:35] I think that is not necessary, because the
renaming did not change the result.
It is always the one error when starting an wx.NET Sample:

  ** (splitter.exe:7803): WARNING **: Failed to load library libwx-c.so
(wx-c): /u
  sr/lib/libwx-c.so: undefined symbol: _ZNK14wxNotebookBase13DoGetBestSizeEv

I searched for this symbol with:
  linux:/usr/lib # grep _ZNK14wxNotebookBase13DoGetBestSizeEv *
and get the result:
  Binary file libwx-c.so matches
  Binary file libwx_gtk2u-2.4.so matches
  Binary file libwx_gtk2u-2.4.so.0 matches
  Binary file libwx_gtk2u-2.4.so.0.0.0 matches
  Binary file libwx_x11univu-2.4.so matches
  Binary file libwx_x11univu-2.4.so.0 matches
  Binary file libwx_x11univu-2.4.so.0.0.0 matches

So it exists int libwx-c.so and in libwx_gtk2u-2.4.so. So from my point of
view everything should work fine.
If I use
  return new wxNotebook();
instead of
  return new _Notobook();
the symbol DoGetBestSize does not exist in libwx-c.so and everything works
fine.

But I do absolutly not understand, why the examples does not run, because
the symbol exists in libwx_gtk2u-2.4.so
