Building ROOT trunk (r40926) with clang on Lion fails

ROOT

Hello,

I am trying to build ROOT trunk (revision is 40926) using clang++ on Mac OS X Lion, but it fails with the following error:

clang++ -dynamiclib -single_module -Wl,-dead_strip_dylibs -install_name @rpath/libNet.5.so -O2 -m64 -mmacosx-version-min=10.7 -o lib/libNet.5.31.so net/net/src/NetErrors.o net/net/src/TAS3File.o net/net/src/TApplicationRemote.o net/net/src/TApplicationServer.o net/net/src/TFTP.o net/net/src/TFileStager.o net/net/src/TGSFile.o net/net/src/TGrid.o net/net/src/TGridJDL.o net/net/src/TGridJob.o net/net/src/TGridJobStatus.o net/net/src/TGridJobStatusList.o net/net/src/TGridResult.o net/net/src/THTTPMessage.o net/net/src/TMessage.o net/net/src/TMonitor.o net/net/src/TNetFile.o net/net/src/TNetFileStager.o net/net/src/TPServerSocket.o net/net/src/TPSocket.o net/net/src/TSQLColumnInfo.o net/net/src/TSQLMonitoring.o net/net/src/TSQLResult.o net/net/src/TSQLRow.o net/net/src/TSQLServer.o net/net/src/TSQLStatement.o net/net/src/TSQLTableInfo.o net/net/src/TSecContext.o net/net/src/TServerSocket.o net/net/src/TSocket.o net/net/src/TWebFile.o net/net/src/G__Net.o -ldl -Llib -lRIO -lMathCore -lcrypto -Llib -lCore -lCint -compatibility_version 5 -current_version 5.31.01

I have configured ROOT (from scratch, i.e.: fresh “svn checkout”) with:

./configure \
  --with-pythia6-uscore=SINGLE \
  --with-f77=gfortran \
  --with-clang \
  --enable-minuit2 \
  --enable-roofit \
  --enable-soversion \
  --disable-bonjour

Enabled features:

asimage astiff builtin_afterimage builtin_ftgl builtin_glew builtin_lzma cintex exceptions explicitlink gviz genvector krb5 ldap memstat minuit2 odbc opengl pgsql pythia6 python reflex roofit rpath shared soversion ssl tmva x11 xft xml xrootd thread

Can somebody help?

Thank you and regards,

Hi again,

turned out to be my fault (leftovers from previous compilations that I thought I have deleted).
