Builds hang post upgrading to Yosemite

[john+macports@…]

This is certainly bizarre. Like everyone who couldn't wait I upgraded to Yosemite. I then pulled the source and recompiled Macports base. All was happy. I think tried to update some of the ports and this happens:

.. and it sits there, doing nothing forever. To trouble shoot this I have:

1) Removed /opt/local and reinstalled Macports (this time using the Yosemite pkg)
2) Nuked my Xcode preferences and re-agreed, etc.
3) Run the assembled command by hand (it works fine, the port builds)
4) dtruss'd the hung process, which appears to be make (what..?)

# dtruss -p 65721
SYSCALL(args) 		 = return

(and nothing)

I've also tried building with a different (new) user to rule out environment variables. I this example I've used bzip2, but it happens for every port. I'm entertaining all sorts of crazy ideas at this point..

[neverpanic (Clemens Lang)]

This may be a shot in the dark, but what does xcode-select -print-path print? Did you install the command line tools? Did you accept the Xcode license agreement (sudo xcodebuild -license)?

[john+macports@…]

$ xcode-select -print-path
/Applications/Xcode.app/Contents/Developer

I did the sudo xcodebuild -license again just for fun; it made no difference. It almost seems like the problem is once the suid to the macports user happens. I've also removed ports, nuked the macports user/group and re-installed again compiling from source. I can't imaging I'm installing incorrectly.

[neverpanic (Clemens Lang)]

That looks correct. Your installation procedure sounds all right as well. Do you run MacPorts from a root account or do you use sudo?

[john+macports@…]

Always with sudo $command. It is however 'sudo bash' if I'm going to be doing port wrangling (failed build, etc.). I've since wiped and rebuilt both ways. I've done a dtruss of it, but I'm not seeing anything particularly useful.

[john+macports@…]

Amusingly enough, I can trigger this again at a different point building pkgconf. This hangs during autoconf, but for the same reason: make
I added -x to configure:

+ printf '%s\n' 'configure:2680: checking whether make sets $(MAKE)'
+ printf %s 'checking whether make sets $(MAKE)... '
checking whether make sets $(MAKE)... + set x make
++ sed 's/+/p/g; s/[^a-zA-Z0-9_]/_/g'
++ printf '%s\n' make
+ ac_make=make
+ eval '${ac_cv_prog_make_make_set+:}' false
++ false
+ cat
+ case `${MAKE-make} -f conftest.make` in
++ make -f conftest.make

which is here

Roughly line 2692

# GNU make sometimes prints "make[1]: Entering ...", which would confuse us.
case `${MAKE-make} -f conftest.make` in
  *@@@%%%=?*=@@@%%%*)
    eval ac_cv_prog_make_${ac_make}_set=yes;;
  *)
    eval ac_cv_prog_make_${ac_make}_set=no;;
esac
rm -f conftest.make
fi

So yet again it looks like there is something strange with make...

macports        99869   0.0  0.3  2577292  26068 s016  S+   11:15AM   0:00.22 /Applications/Xcode.app/Contents/Developer/usr/bin/xcodebuild -sdk  -find make

I may try to completely reinstall Xcode. Make is just in the same = return state.

Make sure you have the Command Line Tools corresponding to your Xcode version and OS X version.

Replying to john+macports@…:

I think tried to update some of the ports and this happens:

As mentioned in wiki:Migration, you should uninstall and reinstall all ports, rather than attempting to upgrade the ports one by one.

[john+macports@…]

I verified the command line tools were the right version. At this point I've completely blown away the entire /opt/local tree and recompiled/installed Macports (more than once). The issue I saw happened regardless of update/install from scratch/port tried. In the end I got tired of this silly game and went for the usual OS X nuclear option.

1) Reboot to recovery mode, repair disk, repair permissions
2) Delete /Applications/Xcode.app re-download, re-install
3) Manually download command line tools from dev.apple.com, install again
4) Wipe then recompile, reinstall macports

.. and joy. I'm honestly not sure what the deal was, but I suspect that since upgrading from 10.8 -> 10.9 -> 10.10 (and all the versions in between) something was unhappy. I'm fairly certain there nothing wrong with the Macports code and I somehow brought this upon myself, so I appreciate the patience and help.

[ryandesign (Ryan Carsten Schmidt)]

I'm sorry we weren't able to pinpoint the problem, but glad you found a way to make it work in the end.
