I am using mainline as of two days ago, but in the interest of full-disclosure, I can't get your testcase to compile unmodified: $ ./cc1plus mipproblem1.ii -quiet In file included from ../../src/algorithms.hh:28:0, from ../../src/ppl_include_files.hh:14, from ../../src/ppl_header.hh:38, from ../../tests/ppl_test.hh:27, from mipproblem1.cc:24: ../../src/Pointset_Powerset.defs.hh:1398:37: error: redeclaration of ‘template<class QH> Parma_Polyhedra_Library::Pointset_Powerset<PSET>::Pointset_Powerset(const Parma_Polyhedra_Library::Pointset_Powerset<QH>&, Parma_Polyhedra_Library::Complexity_Class) [with QH = QH; PSET = Parma_Polyhedra_Library::NNC_Polyhedron]’ may not have default arguments [-fpermissive] The above corresponds to the following code in ppl/src/Pointset_Powerset_defs.hh, which I have had to comment out: // CHECKME: according to the Intel compiler, the declaration of the // following specialization (of the class template parameter) should come // before the declaration of the corresponding full specialization // (where the member template parameter is specialized too). template <> template <typename QH> Pointset_Powerset<NNC_Polyhedron> ::Pointset_Powerset(const Pointset_Powerset<QH>& y, Complexity_Class); Interestingly, the current Fedora package for ppl has a patch for this particular line: +#if __GNUC__ < 5 // CHECKME: according to the Intel compiler, the declaration of the // following specialization (of the class template parameter) should come // before the declaration of the corresponding full specialization @@ -1400,6 +1401,7 @@ template <typename QH> Pointset_Powerset<NNC_Polyhedron> ::Pointset_Powerset(const Pointset_Powerset<QH>& y, Complexity_Class); +#endif Is your attached testcase ./cc1plus-ing unmodified?
