There is a problem with the mysql c++ api and fedora being discussed on the mysql++ mailing list, i thought i might bring it up here as well. The header files and libraries will compile ok, but when compiling actual code gcc gives up errors. This is when we make the examples directory: Compiling, with the gcc3.3 patch installed I get the following error c++ -DHAVE_CONFIG_H -I. -I. -I.. -I../sqlplusint -I../sqlplusint -I/usr/include/mysql -g -O2 -c custom1.cc custom1.cc: In function `void populate_stock(stock*, const MysqlRow&) [with sql_dummy_type dummy = sql_dummy]': custom1.cc:10: instantiated from here custom1.cc:10: error: ambiguous overload for 'operator=' in 's->stock::item = MysqlRow::operator[](int) const(0)' /usr/include/c++/3.3.2/bits/basic_string.h:361: error: candidates are: std::basic_string<_CharT, _Traits, _Alloc>& std::basic_string<_CharT, _Traits, _Alloc>::operator=(const _CharT*) [with _CharT = char, _Traits = std::char_traits<char>, _Alloc = std::allocator<char>] /usr/include/c++/3.3.2/bits/basic_string.h:364: error: std::basic_string<_CharT, _Traits, _Alloc>& std::basic_string<_CharT, _Traits, _Alloc>::operator=(_CharT) [with _CharT = char, _Traits = std::char_traits<char>, _Alloc = std::allocator<char>] make[2]: *** [custom1.o] Error 1 make[2]: Leaving directory `/home/netera/hansson/slask/mysql++-1.7.9/examples' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/home/netera/hansson/slask/mysql++-1.7.9' make: *** [all-recursive-am] Error 2 You can include the header files without a problem but if you add a query object with the << operator, either in one of the examples provided or your own code, gcc returns this error: mycpp.cpp: In function `int main()': mycpp.cpp:12: error: ISO C++ says that `std::basic_ostream<char, _Traits>& std::operator<<(std::basic_ostream<char, _Traits>&, const char*) [with _Traits = std::char_traits<char>]' and `SQLQuery& operator<<(SQLQuery&, const mysql_ColData<const_string>&)' are ambiguous even though the worst conversion for the former is better than the worst conversion for the latter mycpp.cpp:12: error: ISO C++ says that `std::basic_ostream<char, _Traits>& std::operator<<(std::basic_ostream<char, _Traits>&, const char*) [with _Traits = std::char_traits<char>]' and `SQLQuery& operator<<(SQLQuery&, const mysql_ColData<std::string>&)' are ambiguous even though the worst conversion for the former is better than the worst conversion for the latter this is with gcc 3.3.2 and most of the standard fedora core 1 installation. Any input anybody can provide is appreciated in advance. __________________________________ Do you Yahoo!? Get better spam protection with Yahoo! Mail. http://antispam.yahoo.com/tools
