Re: [Reduce-algebra-developers] compiling, for javascript

[Michael S. <sh...@sa...>]

I submitted an issue
<https://github.com/reduce-algebra/reduce-algebra/issues/85> on the github
mirror.

Thanks for the suggestions about updating the makefile.  Changing the
references to allocate.o and cslgc.o does let it get further.  I added
gc-check.o too, although it didn't seem to have any noticeable effect yet.

Now it gets stuck on bytes1.o saying it has no rule to make
../../cslbase/opnames.cpp.  The only file I found with a similar name is
../../embedded/opnames.c, so I tried replacing the reference with that;
that silenced that particular complaint but I don't know if it might cause
problems later.

Next the compilation of ../../cslbase/u01.cpp fails with a bunch of errors
saying "unknown type name 'Save'" and "no matching function for call to
'reclaim'" (it needs 4 arguments).  I grepped through the sources and found
a definition of a 4-argument "reclaim" in csl/embedded/gc.c, which sounds
plausible, but I'm not a C/C++ programmer and I can't guess how to bring
this into scope when compiling the uxx files.  If I just add "gc.o" to the
"main_o_files", as I did with the others, it complains that it has no rule
to make it; and I don't see any references to gc.o or gc.c in the root
Makefile.am.
