libvpx build fails with Xcode 4.3.1

[david.hislop.1@…]

Build of libvpx fails as part of a complete rebuild of all installed ports after upgrade to OS X 10.7.3 (Lion) and Xcode 4.3.1. Prior to it failing the upgrade had successfully built other ports for about 7.5 hours. Also fails as part of a specific build just of libvpx.

It's possible that the problem is missing include paths on the clang command.

I'm using:
OS X 10.7.3
MacPorts 2.0.4
Xcode 4.3.1

Here's what I did:

sudo port selfupdate
xcodebuild -license
sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer
sudo port upgrade outdated

The build failed with:

Checking main.log (attached) I found:

I added /usr/include to the include path and the compile was successful:

$ cat >/tmp/my_test.c#include "stdio.h"int x;
$ /usr/bin/clang -I /usr/include -O2 -arch x86_64 -isysroot -mmacosx-version-min=10.7 -m64 -fomit-frame-pointer -arch x86_64 -O3 -fPIC -E -o /tmp/my_test.o /tmp/my_test.c 
$

So, how do I fix this and get the build to proceed?

[Note, port list libvpx showed the Maintainers as nomaintainer@…, so I've cc'd this there; sorry if that's the wrong thing to do]

Duplicate of #33283, #33351, #33454.

Please:

• verify your libvpx Portfile (port file libvpx will tell you where it is) matches the one on source:/trunk/dports/multimedia/libvpx/Portfile@90164:33-38​, especially the highlighted lines.
• verify xcode-select -print-path returns /Applications/Xcode.app/Contents/Developer or the respective path inside the Xcode.app bundle, in case you moved that.
• verify /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs exists and contains at least one SDK.
• verify you don't have developer_dir set in $prefix/etc/macports/macports.conf.

Then, please run port selfupdate, port clean libvpx and try again.

Thanks, developer_dir was set in $prefix/etc/macports/macports.conf to /Developer, the location where Xcode 3.x was formerly installed. I uninstalled it after installing Xcode 4.3.1.

I don't recall ever setting it myself, although perhaps I ran something when I installed MacPorts a couple of years ago.

How does it get set (apart from editing macports.conf?)

Replying to david.hislop.1@…:

It doesn't, but apparently we shipped a macports.conf containing devleoper_dir /Developer with or before MacPorts 1.8.

[david.hislop.1@…]

Is there a way to refresh macports.conf?

Mine is
