@defvr {Scheme Variable} chicken-build-system
|
||||
This variable is exported by @code{(guix build-system chicken)}.
|
||||
It builds Chicken Scheme modules (also called ``eggs'' or ``extensions'').
|
||||
Chicken generates C source code, which then gets compiled by a C compiler,
|
||||
in this case GCC.
|
||||
|
||||
It adds @code{chicken} to the package inputs, as well as the packages of
|
||||
@code{gnu-build-system}.
|
||||
|
||||
The build system can't (yet) deduce the egg's name automatically, so just like
|
||||
with @code{go-build-system} and its @code{#:import-path}, you should define
|
||||
@code{#:egg-name} in the package's @code{arguments} field.
|
||||
|
||||
For example, if you are packaging the srfi-1 egg:
|
||||
@lisp
|
||||
(arguments '(#:egg-name "srfi-1"))
|
||||
@end lisp
|
||||
|
||||
Egg dependencies must be defined in @code{propagated-inputs}, not @code{inputs}
|
||||
because Chicken doesn't embed absolute references in compiled eggs.
|
||||
Test dependecies should go to @code{native-inputs}, as usual.
