Two problems on MacOS Catalina...

Two problems on MacOS Catalina...

[Perry E. Metzger]

Howdy!

I just built the master branch (Emacs 27) for the first time since
the last release, and I've gotten two problems on MacOS Catalina.

First, for whatever reason, even though configure is finding other
libraries (like jansson), it doesn't seem to find libgmp even though
it's located in the same place. That's minor.

This is a bit worse:

$ emacs
desired fingerprint:
 4255d546e65066d0177c04ba6112773507dd59bbd37d5d7814f8f3d24e77c322
 found fingerprint:
 0e8d2b0f7034ed891fd2020cfc523c70aa7f0d2670e725a5797f4f95a1756124
 emacs: could not load dump file
 "/Applications/Emacs.app/Contents/MacOS/Emacs.pdmp": not built for
 this Emacs executable

I'm not quite sure how to debug that; this was with the first
invocation of emacs immediately after building it and moving the app
bundle into place.

How is it installed? Homebrew, or does it come with the system?

My first thought is to try "make bootstrap;make install" and then copy
the Emacs.app directory again.

MacPorts. Again, it seems like it can find the MacPorts install of
Jansson.

I will try that and report back.

FYI, I'm doing make -j4; I'm wondering if that might be breaking
something?

That works. But: it was never necessary to "make bootstrap" before to
get a working emacs. What has changed, and can it be documented in
INSTALL?

Also, I had to explicitly disable harfbuzz or the build gave me an
error that it had detected but was not using it (whatever that
meant).

FWIW, updating macports according to
https://trac.macports.org/wiki/Migration and doing "make bootstrap"
produced fully working Emacs with no problems.  Did you update macports
properly?

Sometimes it is necessary. I don’t know why but some changes to the
codebase have required ‘make bootstrap’ for as long as I’ve been
building Emacs. Usually a number of people post to emacs-dev asking
why they can’t build master any more.

That’s very strange. I have harfbuzz installed using brew and
configure is clever enough to ignore it.

Was this error before or after doing make bootstrap?

It happened during configure. Here's the exact error:

"configure: error: HarfBuzz wanted, but won't be used.  Maybe some library files are missing?"

In that case, I think it would be good to document this in INSTALL.

It already is documented, only in INSTALL.REPO, not INSTALL.  The
latter is for building a release tarball, where bootstrapping should
never be required.

This should be fixed now.
