ecl/examples/ecl_qt

This demo shows how to embed ECL into Qt5 and serve as kernel. This also discuss how to compile ECL with C++(14). You can extend on this demo to form a more complicate and productive project.

Preparation

Before you build the demo, make sure you have those dependencies installed:

1. ECL, of course. We recommend version 16.1.2.
2. g++/clang compiler with at least C++14 support.
3. make
4. Qt5.x with Qt Creator.
5. Quicklisp installed on your ECL.

We use the external Lisp package :lparallel so you better download that package in advance using (ql:quickload :lparallel).

Build

Build CL Library and FASB

Run make in current directory and you get two files, if successful. lisp-envi.a and hello-lisp-system--all-systems.fasb.

Configure your Qt Project

cd to the directory qt and open that Qt project with your Qt Creator. Change the three paths I marked for you, if necessary.

1. INCLUDEPATH: The path that contains ecl/ecl.h. In Linux it may be /usr/include/.
2. LIBS:The path that leads to the shared library of ECL. In Linux, it may be /usr/lib/libecl.so/.

Build Qt Project

Build your Qt Project. This will generate an executable file for you.

Engage fasb file

After your Qt project is built, move the hello-lisp-system--all-systems.fasb file that generated in build step 1 into the directory containing the executable file.

Run

After you go through the steps above, go for the executable file and try that demo.

Happy hacking with ECL!
