Boost Binary Endian parser not working?
- by Hai
I am studying how to use boost spirit Qi binary endian parser. I write a small test parser program according to here and basics examples, but it doesn't work proper. It gave me the msg:"Error:no match".
Here is my code.
#include "boost/spirit/include/qi.hpp"
#include "boost/spirit/include/phoenix_core.hpp"
#include "boost/spirit/include/phoenix_operator.hpp"
#include "boost/spirit/include/qi_binary.hpp" // parsing binary data in various endianness
template '<'typename P, typename T
void binary_parser( char const* input, P const& endian_word_type, T& voxel, bool full_match = true)
{
using boost::spirit::qi::parse;
char const* f(input);
char const* l(f + strlen(f));
bool result1 = parse(f,l,endian_word_type,voxel);
bool result2 =((!full_match) || (f ==l));
if ( result1 && result2) {
//doing nothing, parsing data is pass to voxel alreay
} else {
std::cerr << "Error: not match!!" << std::endl;
exit(1);
}
}
typedef boost::uint16_t bs_int16;
typedef boost::uint32_t bs_int32;
int main ( int argc, char *argv[] )
{
namespace qi = boost::spirit::qi;
namespace ascii = boost::spirit::ascii;
using qi::big_word;
using qi::big_dword;
boost::uint32_t ui;
float uf;
binary_parser("\x01\x02\x03\x04",big_word,ui); assert(ui=0x01020304);
binary_parser("\x01\x02\x03\x04",big_word,uf); assert(uf=0x01020304);
return 0;
}'
I almost copy the example, but why this binary parser doesn't work. I use Mac OS 10.5.8 and gcc 4.01 compiler.
