从http://code.google.com/p/darungrim/source/browse/trunk/ExtLib/XGetopt.cpp?r=17调用int getopt函数时出错
`check.cpp: In function ‘int main()’:`
check.cpp:14:55: error: invalid conversion from ‘const char**’ to ‘char* const*’ [-fpermissive]
/usr/include/getopt.h:152:12: error: initializing argument 2 of ‘int getopt(int, char* const*, const char*)’ [-fpermissive]

using namespace std;
int main() {
string text="-f input.gmn -output.jpg";
int argc=text.length();

char const * argv = text.c_str();
cout<<"argv: "<<argv<<endl;
int c = getopt (argc, &argv, "f:s:o:pw:h:z:t:d:a:b:?");
cout<<"c: "<<c<<endl;
return 0; …我已经更改了我的代码,现在编译时出现这些错误:
