Are you using solaris studio 12.3 or older? Before version 12.4 there was a bug where partial specialization for templates with same name but in different namespaces (basic_string in std:: and boost::container:: in this case) was considered ambiguous. A workaround for this problem (I would recommend using solaris studio 12.4) can be found here: https://community.oracle.com/thread/3706125 2015-12-22 19:31 GMT+01:00 <dariomt@gmail.com>:
Trying to compile file libs/date_time/src/gregorian/greg_month.cpp I get an error related to Boost.LexicalCast.
I have reduced the problem to a minimal test case:
#include <string> #include <boost/lexical_cast.hpp>
void f(const char* s) { std::string s1(boost::lexical_cast<std::string>(s)); }
My feeling is that this compiler has problems in the specializations for boost::detail::is_stdstring and boost::detail::is_char_array_to_stdstring.
If I remove all those specializations the error goes away. I assume this is not the perfect solution because I guess this will miss some optimization of lexical_cast, but at least I can compile it this way :(
Is there a better solution for this? Has this problem been fixed in 1.60?
