Compiling the GTK binary fails at the linking stage.  Any ideas what might be up or what's missing?  The non-GTK version compiled fine.
Thanks
John

Aha.  It might have been using the latest version, or updating nearly everything on the machine, but it was most probably using gcc-4.2/g++-4.2 instead of v4.3 that finally fixed this for me.
Thanks a lot,
John

I had the same problem with gcc4.3.  The svn update didn't help.  I installed gcg4.2.4 from source, deleted all the .o files and it compiled with MP, and HYPHYMP_GTK brings up a window.

I seem to have had the same problem as John.

pkg-config --version gtk+-2.0
0.23

rpm -q gtk2-devel
gtk2-devel-2.14.7-1.fc10.i386

rpm -q gtk2
gtk2-2.14.7-1.fc10.i386

rpm -q gcc
gcc-4.3.2-7.i386

I got the same undefined reference to `hyphy_menu_item_callback(void*, unsigned int, _GtkWidget*) errors with the svn update.  I was able to compile with gcc 4.2.

Hi guys,

I can confim that compiling with gcc-4.2 and g++-4.2 does the trick. Note that on (K)Ubuntu9.04, and probably 8.10, gcc-4.3 and g++-4.3 is the default.

For those that don't know how this works.

1) Install gcc-4.2 and g++-4.2
2) Change the gtk-build.sh variables:
COMPILER="g++-4.2";
COMPILERC="gcc-4.2";

Now the linking works.

FYI, with gcc/g++ you have a linking error if you see this message:

collect2: ld returned 1 exit status
Finished

Regards

Found and fixed the compilation bug.

SVN version 518 and above should build properly.
