expat configure failure with Xcode 4.3 beta

[alex.godbehere@…]

I'm trying to install dnsmasq to use my PC as a siri server. When I execute the command: sudo port install dnsmasq I get the following error.

--->  Computing dependencies for dnsmasq
--->  Dependencies to be installed: xz gettext expat libiconv gperf ncurses ncursesw

Error: Target org.macports.configure returned: configure failure: shell command failed (see log for details)

The log you attached was not complete. Please run the following and attach the new log if it fails.

sudo port clean expat
sudo port install expat

When I run install expat, I get

You did not attach the log as requested. You have not told us anything useful.

[alex.godbehere@…]

No, i can't execute the commands that you asked me, as the second one produces the above error.

[alex.godbehere@…]

Oh, my bad. I'll attach the logs.

Expat Log

[ryandesign (Ryan Carsten Schmidt)]

Ok, the log says:

:info:configure checking for gcc... /Applications/Xcode.app/Contents/Developer/usr/bin/clang

I have not seen compilers installed in this location before, but perhaps that's where Xcode downloaded from the Mac App Store is putting it these days. What version of Xcode is this, and how did you install it?

:info:configure checking for C compiler default output file name... configure: error: C compiler cannot create executables

MacPorts may be having trouble using clang from this (up to now?) unusual location. This may be what r88540 / r88541 were supposed to fix. If so, you'll need a newer version of MacPorts than 2.0.3; since we haven't released a newer version yet, you could try ​building MacPorts from trunk. Alternately, the problem might be that you haven't installed Xcode correctly, as per the FAQ entry for this error message.

:info:configure See `config.log' for more details.

This file may contain additional insight; you could attach it and we could have a look.

Are you using a prerelease of Xcode 4.3?

[alex.godbehere@…]

Yes, I have the Beta.

[ryandesign (Ryan Carsten Schmidt)]

Ok, then this is solved by the aforementioned fix, and you need to build MacPorts from trunk. By the time Xcode 4.3 is released hopefully we will have a new release of MacPorts incorporating this fix. In general we don't support the use of pre-release versions of Xcode or OS X with MacPorts.

[alex.godbehere@…]

Thanks, when I do this however, I get the error

Warning: No index(es) found! Have you synced your source indexes?

[ryandesign (Ryan Carsten Schmidt)]

Run "sudo port sync" to sync your ports and rebuild the index.

[dkocher@…]

There is still the same issue with Xcode 4.4 installed.

xcodebuild -version
Xcode 4.4

As per the warning in the log file, reinstalling the Command Line Tools after upgrading XCode (from XCode → Preferences → Downloads → Components will fix this.

[ryandesign (Ryan Carsten Schmidt)]

As you've already discovered, you must install (or upgrade) the command line tools after installing (or upgrading) Xcode, as we document in our ​installation instructions.
