[Ecls-list] building a static library that depends on CFFI

thank you for taking the time to fix this bug. I'm sorry it took me so
long to come back to this.
I tried it, and the static library compiles without problems. Thank you.
My goal is to make a static library that is linked against a C library.
Let's say there is function in a C library that I call from some Lisp
code. I would like to compile this Lisp code to a static library.
I used the low-level FFI of ECL, I included the header of the library
using CLINES, and I wrapped the C function in a Lisp function with
C-INLINE. This worked very well.
Now, I would like to achieve the same using CFFI instead of FFI. Using
CFFI I tried several approaches, but I wasn't successful. Basically, I
compiled the Lisp code into a static library, but the produced library
seems not to include the C library. I tried to load the library at
compile time with FFI:LOAD-FOREIGN-LIBRARY, but it doesn't seem to
have any effect.
I'm sure there's something I'm missing. Is it possible to achieve
this? If so, how can I go about it?
Thank you very much!
