Sure! Please find attached two examples. The examples use the "sin" function from libm.
What I'm trying to achieve is producing a static library that makes use of foreign functions. The ECL I'm using is built without DFFI. I'm using the latest version from git. In each example you can LOAD the file `build.lisp' into ECL (please, change the paths as necessary). It should create a static library for the corresponding example. Then, you can use `make' to build an executable that is linked against the static library. The first example is ffi-test. It contains an example using the low-level FFI of ECL. This example works nicely. The other example is cffi-test. Lamentably, I haven't managed to make it work. I would like to reproduce the functionality of ffi-test in cffi-test. That is, I would like to produce a static library that uses CFFI to access foreign functions. I'm sure I'm missing something in cffi-test. I've tried different ways of compiling, but with no success.
