Invalid conversion from bool


Dear Advanced c/g++ on boost programers:

I have copied and testd a simple (Copy a file with Boost) program from page 372, Example10-10, book(C++ cookbook)
but I got compile error
-----------------------------
eric_at_eric-laptop:~/cppcookbook/ch10$ g++ Example10-10.cpp
Example10-10.cpp: In function ‘int main(int, char**)’:
Example10-10.cpp:17:47: error: invalid conversion from ‘bool (*)(const std::string&)’ to ‘boost::enable_if_c<true, void>::type*’
Example10-10.cpp:17:47: error: initializing argument 2 of ‘boost::filesystem3:ath:ath(const Source&, typename
-----------------------------------------------------
// Example 10-10. Copying a file with Boost
#include <iostream>
#include <string>
#include <boost/filesystem/operations.hpp>
#include <boost/filesystem/fstream.hpp>
#include <boost/filesystem/path.hpp>

using namespace std;
using namespace boost::filesystem;

int main(int argc, char** argv) {

// Parameter checking...

try {
// Turn the args into absolute paths using native formatting
path src = complete(path(argv[1], native));
path dst = complete(path(argv[2], native);
copy_file(src, dst);
}
catch (exception& e) {
cerr << e.what() << endl;
}

return(EXIT_SUCCESS);
}
----------------------------------------------------------------------------
I ever check around web, there is some suggestion ask me to get rid native, but in my test/system, it only
generate more errors.
my boost version probably is 1.46.1
and I am on g++ 4.5.2 and Ubuntu10.04/linuxKernel2.6.35-25
Need and thanks your help a lot in advance, Eric

Missing ")" bracket on line 17.
Code:
path src = complete(path(argv[1], native));
path dst = complete(path(argv[2], native);// <------- here

problem still

the compile error is from first
path src = complete(path(argv[1], native));
if you do not believe, please download that example code by yourself, I just tested, that download code can not compiled in my
gcc and boost

It compiles on MSVC2008 express and the only error is missing ")" bracket. Add bracket and try again.
