Yes, Jan. The switch for configure will make difference. This is also true
for Windows platform. I drafted one PR
https://github.com/apache/couchdb-glazier/pull/11/files for Windows
platform.
Below is one fro Debian and I notice that most of them are the same as
yours now but `make j4` which will make compile faster.

Thanks to Joan, Paul and
https://urldefense.proofpoint.com/v2/url?u=https-3A__twitter.com_map&d=DwIFaQ&c=jf_iaSHvJObTbx-siA1ZOg&r=PKZ65oA9tV05sXjYYyZUJf_d-ASaaLXiLw-gQdWPDsQ&m=gAC474eVypB0az_jWlFjWV1wXNtFR4yUEF0OqvxqjyA&s=twpZaJ9jipxmC-iB4O106jvTkjITbty5VIF__px8Z1A&e=
, I’ve got it working. The trick was slightly different ./configure
options for SM60:
https://urldefense.proofpoint.com/v2/url?u=https-3A__github.com_janl_homebrew-2Dcouchdb_blob_master_Formula_spidermonkey60.rb&d=DwIFaQ&c=jf_iaSHvJObTbx-siA1ZOg&r=PKZ65oA9tV05sXjYYyZUJf_d-ASaaLXiLw-gQdWPDsQ&m=gAC474eVypB0az_jWlFjWV1wXNtFR4yUEF0OqvxqjyA&s=OkgFS-ZYhmuxDEfLfHvrZucVZwvS14wzQLGu4qKBfRo&e=
the --disable-jemalloc and --enable-posix-nspr-emulation options seem to
have done the trick.
Thanks all!

normally rebar should pick that up on its own, but it doesn’t. If I don’t
do this, I get a number of other errors, where research had convinced me to
make this particular change:

js_alloc() is an inline function, which is, I think, why we get the
_moz_arena_malloc missing reference in our util.h, because we are not
calling out to any external functions actually.

suggests that if js_malloc() were an `inline` function, that would
explain the situation, and a fix would be to mark it `static inline`.
Unfortunately it is already a `static inline`.
