G++33 not the first paper on freebsd4.8 I freebsd4.8 g++33 installed, but not the first time a translation of documents, with an error message as follows : `string Error : 'undeclared (first use this function) Etc. -I/usr/include/g++ Added, also showed alloc.h, string and many other mistakes in the first document. I use ports installed, I - I read : -I/usr/local/lib/gcc-lib/i386-portbld-freebsd4.8/3.3.4/include Or find the first document. Will g++33 how the distribution of programming environments? Thank you. Incidentally, the above-mentioned examples, in the Linux can be translated to the next. [code] #include "Iostream>; #include "String>; Int main () { S string If (s.empty ())    { Cout "" "s is empty," "" endl;    } Else    { Cout "" "s is not empty," "" endl;    } } [/code] G++33 not the first paper on freebsd4.8 #include "Iostream>; #include "String>; Using namespace std; What does this mean? Translated by using Linux? What problems do you have? G++33 not the first paper on freebsd4.8 Freebsd4.8, tacit g++2.95 Linux is installed on /usr/bin/ under. I used g++33 installed under the /usr/local/bin Now Linux can be used, but not used g++33 G++33 not the first paper on freebsd4.8 Very grateful. I have not added to the proceedings Using namespace std; Linux in China (version 2.95) can be used. In g++33, to be named the designated space. Thank lenovo withheld [ Closed window ]
