I downloaded the archive from https://github.com/nomad-software/tkd and files are same as in the git repo. Tcl/tk is installed on this machine (test 'hello world' script works fine) but I get this error when compiling the example from the github page:

tkd/interpreter/tcl.d(16): Error: module tcl is in file 'tcltk/tcl.d' which cannot be read
import path[0] = /usr/include/dmd/phobos
import path[1] = /usr/include/dmd/druntime/import

As far as I can see there is no tcltk directory - can someone tell me where I'm going wrong or if something is missing?

TIA

Paul

AFAICS tkd requires too additional libraries (bindings): tcltk and x11. Its easiest to
use DUB for building, it will download all required dependencies and pass the correct import paths to the compiler. The following works for me:

dub.json:
    {
        "name": "tkd-test-app",
        "dependencies": {
            "tkd": "~>1.1.4"
        }
    }

source/app.d:
    (the example program)

Running "dub" successfully builds and executes the example program.

If you don't want to use DUB, you need to download the other two packages from code.dlang.org and specifiy "-I/path/to/tcltk -I/path/to/x11 -I/path/to/tkd" in the DMD invocation.

Thank you, I'll try that.

Added info: I wanted to avoid using dub so I could manually figure out what would be required to distribute the application.

Using dub I get this during linking:

Building tkd-test ~master configuration "application", build type debug.
Compiling using dmd...
Linking...
/usr/bin/ld: cannot find -ltcl
/usr/bin/ld: cannot find -ltk

...any suggestions please?

You need to install the libraries. Ex `sudo apt-get install libtcl8.5 libtk8.5`

Or the corresponding -dev packages.

Hmmm, I have libtcl8.6 and libtk8.6 installed already. The only dev packages I see are tclcl and tclap - I can't find any libtk -dev package.

I was hoping to keep a tight rein on what was required to be installed to simplify deployment but its spiraling out of control again LOL.

Someone more familiar with Debian/Ubuntu than me may be able to help you here, sorry.

The -dev packages are only required during development (specifically at link time), the resulting binary only needs the normal packages installed.
