1. Start from a clean build with native compilation
2. Modify a .c file in src to trigger a recompilation
3. gmake in src
=> error "trying to dump non fixed-up eln file" when dumping
bootstrap-emacs.pdmp. Always.
I find this very inconvenient, esp. since this never happens without
native compilation. Only thing that works currently is to make in the
toplevel directory.
The reason for this is src/Makefile uses ELN_DESTDIR and BIN_DESTDIR in
rules, but does not contain definitions for them. In a toplevel make,
both are defined on the command line when invoking "gmake -C src
ELN_DESTDIR=...".
When making in src, ELN_DESTDIR is therefore empty, and temacs is called
with with --eln-dest empty. Loadup.el then does its thing and calls
load--fixup-all-elns before dumping. That function decides to not set
native compilation units' file member to a cons, and "trying to dump non
fixed-up eln file" is then issued when dumping such a CU.
I don't know what the right fix for this is, maybe load--fixup-all-elns
should work differently. As a workaround, it apparently suffices to add
default values to src/Makefile like so:
ELN_DESTDIR=not-set
BIN_DESTDIR=not-set
