Hello,
I get this kind of error:
s2.cc:24: choosing `std::basic_ostream<char, _Traits>&
std::operator<<(std::basic_ostream<char, _Traits>&, const char*) [with
_Traits = std::char_traits<char>]' over `SQLQuery&
operator<<(SQLQuery&, const sql_ColData<std::string>&)'
s2.cc:24: because worst conversion for the former is better than worst
conversion for the latter
make: *** [s2] Erreur 1
using Mysql++ API 1.7.9 with FLAGS for compiling:
CPPFLAGS = -g -v -Wold-style-cast
I get as result a list of warning of tis type:
/opt/mysql++/include/coldata2.hh:35: warning: use of old-style cast
/opt/mysql++/include/coldata2.hh: In function `char
operator<<(mysql_ColData<Str>, char)':
Can i explicitely, with a cast, or with a flag tell to gcc that I want
to use : SQLQuery& operator<<(SQLQuery&, const
mysql_ColData<std::string>&) ?
Thanks, for help
Olivier
