Hi,

I am trying to compile GiNaC under OS X with clang++ and the usage of libc++ (this is required, as my project, where I want to include GiNaC requires the c++11 standard).

Therefore I added the following configuration options:

./configure CXX=/usr/bin/clang++ CXXFLAGS="-std=c++11 -stdlib=libc++" LDFLAGS="-stdlib=libc++"

Upon invoking make I get an error regarding an ambiguous conversion in multiple lines:

inifcns_nstdsums.cpp:2604:18: error: ambiguous conversion for functional-style cast from 'int' to 'lst' (aka 'container<std::list>')

return e * (-H(lst(0),1/arg).hold());

^~~~~

./container.h:145:2: note: candidate constructor

container(STLT const & s, bool discardable = false)

./container.h:167:11: note: candidate constructor

explicit container(const ex & p1)

All errors are in the above file inifcns_nstdsums.cpp and occur with the same cast:

H(lst(0),1/arg).hold()

From the error message I can conclude that there are two constructors applyable - which one is the correct one? E.g. casting 0 to ex (changing the line to: H(lst( ex(0) ),1/arg).hold() solves the error - is this the correct cast or is the other cast the correct one?

Best Stefan
