Inspecting intermediate C files

[Daniel Kochmański]

Hi,

I'm not sure if I miss something, but this mail seems to be sent to the
ecl-devel-owner at common-lisp.net . Correct ML address is
ecl-devel at common-lisp.net . I'm fast forwarding the mail there.

Generated code is readable, but it's a generated code after all. It's
not pretty.

To prevent ECL from deleting these intermediate files you need to set
special variable c::*delete-files* to nil.

  (setf c::*delete-files* nil)

Intermediate files are *.c, *.h and *.data . The last one contains some
untranslatable expressions (rare occasion – if you work with infinities
for instance) and debugging/reflection information (like the path to the
source file).

This problem has been tacled by Earl Ducaine here:

I'm now in-process of revising manual and rewriting it into texi
sources. I'll keep in mind to document this. It would be great
if you could file an issue on
gitlab.com/embeddable-common-lisp/ecl/issues (with the label
"documentation"). Thanks!
