Summary:

Attempting to use distributed builds with Xcode 4 fails. Machines have both Xcode 3.2.6 and Xcode 4.0.2/Build 4A2002a (installed in that order). All machines are running OS X 10.6.7.

Steps to Reproduce:

1) Setup multiple machines to enable distributed builds (see the attached 'distributed build settings.png')

2) Unzip test.zip (attached), and use Terminal to cd to that directory.

3) run: 'defaults write com.apple.dt.Xcode XCDistributedBuildsVerboseLogging 1'

4) run xcodebuild

Expected Results:

main.m will be compiled in a distributed fashion by distcc

Actual Results:

rmangino-17mbp:test rmangino$ xcodebuild
distcc[3108] (dcc_parse_multiplier) ERROR: bad multiplier "/0,lzo,cpp" in host specification
distcc[3108] (dcc_show_hosts) CRITICAL! Failed to get host list
/Xcode4/usr/bin/pump: error: pump mode requested, but distcc hosts list does not contain any hosts with ',cpp' option
