erlang @19.1_0+hipe+ssl.darwin_10.x86_64 fails to compile/assemble?

[macportsraf]

Upgrading, cleaning, uninstalling and reinstalling didn't work. Here are the errors from the logfile:

Build log failing at the same place.

This ticket is almost 4 years old. Is anyone looking into this?

[kencu (Ken)]

looks like erlang built fine on 10.6.8 through the 18.x series, but stopped as of the 19.x series. Cause is not obvious from the (previous) log. May or may not be fixable. 10.6.8 has limited ( but loyal! ) users now, and resources on Macports focus on the tickets involving the past three system versions, which affect 99% of users.

Some assistance is needed. Did you try forcing a newer compiler?

[kencu (Ken)]

the website says erlang still supports 10.6.8, so that is encouraging.

[kencu (Ken)]

OK. It installs:

$ port -v installed erlang
The following ports are currently installed:
  erlang @20.3_0+hipe+ssl (active) platform='darwin 10' archs='x86_64' date='2018-05-12T10:30:23-0700'

My system is set up with LibcxxOnOlderSystems, and defaults to macports-clang-3.9 as a compiler. I did not see the error you saw above, so presumably my newer compiler got by that error.

However, the build did error out on the patch that was put in for 10.6 some years ago

That was funny -- looks like it's not seeing the CoreFoundation headers on 10.6.8. I just deleted that patch, and then it built right on through to the end without any troubles for me.

SO: for you to get it built, without going through the whole LibcxxOnOlderSystems routine, I would try a newer compiler, like this perhaps:

sudo port -v install clang-3.9
sudo port -v install erlang configure.compiler=macports-clang-3.9

you can either take out the patch in the Portfile now, or try it yourself, and if it errors, delete the patched bit from:

erts/emulator/sys/unix/erl_unix_sys_ddll.c

like I did.

Still to be considered: that patch was put in there for a reason, as per the note in the Portfile. It should still work. It would probably be best to figure out why the CFInitialize definition can't be found, and fix that -- possibly by including the header in that file? I'm not sure about that just now.

In 66b25e1930aecb7642060ecaf1d471f4e830e830/macports-ports (master):

erlang: blacklist gcc-4.2

Fixes: #52507

[kencu (Ken)]

Interesting. This forces the build to llvm-gcc-4.2, which doesn't error on the implicit function definition like clang-3.9 does:

sys/unix/erl_unix_sys_ddll.c:57: warning: implicit declaration of function ‘__CFInitialize’

and I guess finds the objects at the link, in the end.

If we disable the error for implicit function defs, that should fix the rest of the builds with newer compilers.

Now why, I wonder, don't newer clangs error out on that as well, I wonder?

By the way on Rosetta it fails. To begin with, llvm-gcc-4.2 begins building for Intel. When --build=powerpc-apple-darwin${os.major} is added, it starts building for PPC, but then fails on:

BROKEN KQUEUE!
Erlang has been compiled with kernel-poll support,
but this OS X version is known to have kernel bugs
when using kernel-poll. You have two options:
 1) update to a newer OS X version (OS X Sierra or newer)
 2) recompile erlang without kernel-poll support

So instead for Rosetta blacklist should include *gcc-4.* (then all the rest gets correct automatically, no need to specify --build=).

gcc12 gives a number of warnings:

../include/internal/ethread.h:44: warning: "__ppc__" redefined
   44 | #define __ppc__

But the build succeeds.

For PPC it does error, though differently.
