Hi Stephen,
Hi all,
I am having a small problem with boost's program options library.
In the documentation it states that to parse a command file you are suppose to use the "parse_command_file" function as follows:
parse_config_file("example.cfg", desc)
When attempting this, my compiler (gcc 3.3.3) issues an error stating:
decoder.cpp:61: error: no matching function for call to `parse_config_file( const char[12], boost::program_options::options_description&)'
It appears that opposed to calling the constructor for basic_istream the compiler attempts to find a function with char[12] as the first argument. To circumvent this error I can do the follow:
Std::ifstream in( "config.cfg" );
Parse_config_file( in, desc );
And it works. I would rather use the first method opposed to the second so is there someway for it to be used instead?
I'm afraid no. The document and the code got out of sync and the code provides only parse_config_file(istream&, const options_description&). Since istream does not have any meaningfull constructor, passing string does not work. I'll fix this, but this might be post 1.33 due to feature freeze. - Volodya
