Testing ECL (Embeddable Common Lisp)

Procedure Build static libraries (steps):

Generate hello.o

ecl > (compile-file "hello.lisp" :system-p t)

Generate bye.o

ecl > (compile-file "bye.lisp" :system-p t)

Generate static library "libhello-bye.a"

(c:build-static-library "hello-bye" :lisp-files '("hello.o" "bye.o") 
                                    :init-name "init_hello_bye")

C source

init_hello_bye is referenced in C source.

For execute only the lisp function use:

cl_object result = cl_eval(c_string_to_object("(hello)"));

For print from C/ECL use:

ecl_print(result, ECL_T);

For newline use:

ecl_terpri(ECL_T);

Notes of the source

This source begin in:

cl_boot(argc, argv);

and end in:

cl_shutdown();

Building ECL (from source)

wget -c https://common-lisp.net/project/ecl/static/files/release/ecl-20.4.24.tgz in /usr/local/src
tar -xf ecl-20.4.24.tgz
cd ecl-20.4.24/
./configure --prefix=/usr/local
make
make install

For build my binary with the static library:

cc -o hello hello-bye.c libhello-bye.a -lecl
./hello
Hello, world
"Bye."

(about) hello.lisp

In this function return a "hello, world" but using princ

(about) bye.lisp

In this function return a "Bye." but using print.
