[geos-devel] OS X 10.7 Lion llvm problem

[William Kyngesburye]

Lion's Xcode now defaults to the llvm compiler (symlink gcc and g++ to the llvm).  I get an error:

Linking CXX shared library ../lib/GEOS.framework/Versions/3/GEOS
Undefined symbols for architecture x86_64:
  "__ZNSt8auto_ptrIN4geos4geom8EnvelopeEEcvSt12auto_ptr_refIT_EIS2_EEv", referenced from:
      virtual thunk to geos::geom::GeometryCollection::computeEnvelopeInternal() constin GeometryCollection.cpp.o

      virtual thunk to geos::geom::GeometryCollection::computeEnvelopeInternal() constin GeometryCollection.cpp.o
ld: symbol(s) not found for architecture x86_64


Is this worth a bug report?  

standard gcc/g++ (configure with gcc-4.2/g++-4.2) compiles OK.  Though it brings back the test problem:
