Linker error (OS X) #4

Closed anna-hope closed 10 years ago

anna-hope commented 10 years ago

When I try to build the example, it fails with:

"Undefined symbols for architecture x86_64: "_Tcl_MainEx", referenced from: _Tcl_Main in tkd.o"

Any ideas?

It looks like you haven't linked to tcl. What platform are you on, what version of tcl/tk do you have installed and how did you try and build the example?

anna-hope commented 10 years ago

I'm on OS X. I downloaded Tcl 8.6.1 from ActiveState, and I'm trying to build with 'dub --config=example.'

As far as i'm aware Tcl/Tk is already installed on MacOS but installing the ActiveState version shouldn't hurt. Check that your Tcl/Tk libraries are able to be found on the command line. Try:

echo $PATH;

and make sure the libs are located in one of those paths. You can also try:

locate libtcl.so;
locate libtk.so;

to find where Tcl/Tk is. Mine is located in /usr/lib/ and looks like this:

lrwxrwxrwx   1 root root           26 Jan 23 18:56 libtcl.a -> /usr/local/lib/libtcl8.6.a*
lrwxrwxrwx   1 root root           27 Jan 23 18:56 libtcl.so -> /usr/local/lib/libtcl8.6.s
lrwxrwxrwx   1 root root           25 Jan 23 18:57 libtk.a -> /usr/local/lib/libtk8.6.a*
lrwxrwxrwx   1 root root           26 Jan 23 18:57 libtk.so -> /usr/local/lib/libtk8.6.so*
etc...

These are the libs that need to be linked to your program in order for it to function correctly.
