I tried building it myself but it didn't compile.
Which ports did you use?
I tried with wxgtk28-unicode and db42-4.2.52_5 & db50-5.0.21.0
Here the latest attempt:

Looks like your wxWidgets and STL - you should compile your own wxWidgets from the 2.9 release.
Use something like this to configure it and adjust the reference paths in your makefile.unix
Quotemkdir buildgtk cd buildgtk ../configure --prefix=/home/my_user/bitcoin/deps \ --with-gtk \ --disable-shared \ --disable-debug_flag \ --enable-stl \ --enable-utf8 \ --with-libjpeg=builtin \ --with-libpng=builtin \ --withregex=builtin \ --with-libtiff=builtin \ --with-zlib=builtin \ --withexpat=builtin
It doesn't work with wxWidgets 2.8, it needs wxWidgets 2.9. Unfortunately, there isn't a Debian package of wxWidgets 2.9 yet.
