llvm dev - Dec 2008 - [LLVMdev] Trouble Building llvm-gcc-4.2

I'm almost finished with the BuildBot validation config, but I'm having 
trouble convincing it to compiler llvm-gcc-4.2.

Here's the relevant portion of the config:

  f.addStep(SVN(workdir="llvm-gcc-4.2/src", mode='clobber', 
baseURL='http://llvm.org/svn/llvm-project/llvm-gcc-4.2/', 
defaultBranch='trunk'))
  checking=""
  if optimized == "--disable-optimized":
    checking="--enable-checking"
  f.addStep(Configure(workdir="llvm-gcc-4.2/obj",
command=["../src/configure",
WithProperties("--prefix=%s/install", "absbuilddir"), 
"--program-prefix=llvm-", 
WithProperties("--enable-llvm=%s/build-llvm-initial/obj",
"absbuilddir"),
"--enable-languages=c,c++", checking]))
  f.addStep(WarningCountingShellCommand, workdir="llvm-gcc-4.2/obj",
name =
"llvm-gcc-4.2_clean", command="make clean", haltOnFailure =
True,
description="cleaning llvm-gcc-4.2", descriptionDone="clean
llvm-gcc-4.2")
  f.addStep(WarningCountingShellCommand, workdir="llvm-gcc-4.2/obj",
name =
"llvm-gcc-4.2_compile", command="nice -n 10 make bootstrap",
haltOnFailure =
True, description="compiling llvm-gcc-4.2",
descriptionDone="compile
llvm-gcc-4.2")
  f.addStep(WarningCountingShellCommand, name =
"llvm-gcc-4.2_install",
command="nice -n 10 make install", haltOnFailure = True, 
description="installing llvm-gcc-4.2", descriptionDone="install 
llvm-gcc-4.2")
  f.addStep(DejaGNUTester(description="testing llvm-gcc-4.2", 
descriptionDone="test llvm-gcc-4.2",
workdir="llvm-gcc-4.2/obj"))

Note that I pass --enable-llvm=<abs llvm obj dir> to configure for 
llvm-gcc-4.2.  However, the build fails with:

configure: error: You must specify valid path to your LLVM tree with 
--enable-llvm=DIR

The initial configure of llvm-gcc-4.2 works just fine.  It's the actual
build
that fails, when the configure is done is subdirectories as part of "make 
bootstrap."

Any hints?

Are you sure buildbot provides absbuilddir?

How does the configure line actually look like? (stdio output)

Yes, I wrote a BuildStep to compute it.  I know it picks it up because the 
error used to tell me to provide an absolute path.  That happened during
the configure stage.

The initial configure runs as:

./src/configure 
--prefix=/ptmp/dag/buildbot/slaves/llvm-validate/llvm-validate-debug-x86_64-linux/build/install
--program-prefix=llvm- 
--enable-llvm=/ptmp/dag/buildbot/slaves/llvm-validate/llvm-validate-debug-x86_64-linux/build/build-llvm-initial/obj
--enable-languages=c,c++ --enable-checking
 
During the build stage, make outputs:

Configuring stage 1 in ./gcc
configure: loading cache ./config.cache
[lots of checking messages...]
checking for dsymutil... no
dsymutil is not available
configure: error: You must specify valid path to your LLVM tree with 
--enable-llvm=DIR
