Re: [Chicken-users] Compiling eggs to .c

[Norman Gray]

Greetings, once more.

...coming back to this after a pause (I am, just as before, trying to 
compile a Chicken program, and its associated eggs, to C, for later 
compilation without an installed Chicken system).

I'm trying, at one point in the compilation, to build the abnf egg, 
alongside about 40 others (this is not the only remaining error, but it 
might indicate what I'm doing wrong).  It fails, giving an error:

    Error: during expansion of (import ...) - unbound variable: 
|\xcf\xfa\xed\xfe\x07\x00\x00\x01\x03\x00\x00\x00\x08\x00\x00\x00|

(the fuller output is below).  This error message doesn't really signal 
clearly what it is I'm doing wrong.  The fuller output suggests that 
something's going wrong importing the 'input-classes' module, but trying

    CSC_OPTIONS="-unit abnf -include-path ../input-classes" 
chicken-install -n

pointing towards the (apparently successfully built) input-classes egg, 
doesn't help.  Trying '-include-path ..' doesn't work either, but by 
this stage I'm just guessing.

It's clearly _something_ to do with the dependencies on other eggs, 
because an egg with no dependencies (eg 'make') builds OK.

chicken-install -h doesn't give any clues (the -scan option looks 
promising, but when trying it, it clearly does something different from 
what's needed here).

Looking through chicken-install.scm for things like 'include' or 'path', 
and grepping the Chicken source's *.scm for 'include-path', doesn't 
provide any sudden enlightenment.

Can I just check I've understood things: it is supposed to be possible, 
isn't it, to compile a non-trivial Chicken program, which uses eggs, to 
a collection of .c files which can be compiled without a Chicken 
install?  That's certainly what's suggested by the end of 
<http://wiki.call-cc.org/man/4/Using%20the%20compiler>.  That page says 
'For more information, study the CHICKEN source code'; I'm game, but 
that's... quite a tall order.

Any pointers would be much appreciated.

Best wishes,

Norman
