Hello, Apparently, some pcre header files don't work any more, at least on amd64. /usr/local/include/pcre_stringpiece.h needs to include bits/type_traits.h. But type_traits.h has moved from bits/ to ext/. Even then, including pcre_stringpiece.h barfs out: pcre_stringpiece.h:165: error: '__type_traits' is not a template pcre_stringpiece.h:165: error: explicit specialization of non-template '__type_traits' pcre_stringpiece.h:166: error: '__true_type' does not name a type
On a gcc3 host, it compiles just fine. Best regards, -Frank.
