Building Boost with MS Platform SDK AMD64 Cross-compiler

2007-07-16T20:30:00.000+05:30

This post has been pretty hastily put together. I intend to change this over time and document how I built Boost libraries from source using the Microsoft Platform SDK 2003, for the x64 platform (AMD64 / EM64T).

1. Boost 1.31 - had to choose this rather older release because of certain constraints that our product has.

2. Microsoft Platform SDK 2003 R1. (Installed at "C:\Program Files\Microsoft Platform SDK") - no Visual Studio installation exists.

3. Using Boost.Build V1 rather than 2. Here is a mssdk-amd64-tools.jam file I created using the msvc-tools.jam at the following location under the Boost source dir:

boost_1_31_0\tools\build\v1

4. Everything seems to build fine except Boost.Regex. This fails while linking - apparently it cannot find a large number of template specializations of standard library classes for wchar_t.

The errors are shown below.

- Any idea why these symbols are not available.

- Is there a way I can turn off building Unicode support for Boost.Regex - can undef-ing BOOST_NO_WREGEX be of any help or should it be done with some other preprocessor symbol.

Basic terminal manipulation with C++ and ncurses

2007-04-18T15:19:00.000+05:30

This one is a rather hastily written post. I frequent many online forums where newbies mob the lists and cause endless pain to the moderators with questions relating to some really evil non-standard ways of writing code that some compiler vendors of the Real Mode age popularised with their insipid IDEs. A large part of this concerns how to "clear the screen", "read a key press" and "position the cursor at some specified location" on the terminal screen.

I kind of figured out a plausible reason for this obsession with terminal manipulation. For some reason, the second program that some of these blokes have ever written after the customary "Hello, World!" was something like:

#include <stdio.h>
#include <conio.h>

void main()
{
clrscr();
printf("Hello, World!\n");
getch();
}

Now I don't mean to be taken too seriously on this "second program" thing, but what I do mean is that too many youngsters have tried writing programs like the one above without much clue about where all they are going wrong.
If you feel revolting while reading code in non-monospace red font you are with me. But at this point, if you do not have bigger concerns about this code than the typesetting, then read on, cause you ought to have had, and having not had it, you need enlightenment. If you do have, read on all the same because you might still need the technique described below.

The above program is awful, for a number of reasons - all of which relate to a severe flouting of coding standards and in fact a severe breach of language standards by compiler which encourages and compiles such code. void main is of course wrong, but conio.h is not a standard header, nor are clrscr() and getch() standard functions.

Clearing the screen is a no-no

Apart from the syntactic issues, there are semantic issues in this piece of code as well. Know this, if you are writing a text console-based application, normally you will not want to clear the user's screen through your code. You never know what kind of terminal the user is using and what kind of data might be on display on this terminal. If the terminal is of the kind that can't be scrolled back, and there was sensitive data on display that the user somehow needed, and you happen to clear the screen just as you started your program - then at the least you have helped the user to a pretty bad experience, and at the most your company can be sued for losses or at least your product can earn a bad usability rating.

Keypress inputs are not cool

Blocking on a keypress with getch() would have been fine in the above example, had getch been standard. But even if it was standard, taking single character inputs from the user in the form of keypresses is a pretty bad idea, if the key pressed by the user matters to the program. There are some exceptions to it, but in general you would want the user to type exactly what she means, take a long hard look to make sure that this is indeed her intended input, and then confirm by hitting the Return key. Thereafter, the input is yours. But you don't want to process accidental key-presses as valid inputs. Barring exceptions, the general rule of thumb is, then:

1. Do not clear the user's screen on your own
2. Do not take important inputs as key presses.

The ncurses way

Even if we agree on the semantic rules of terminal manipulation above, we still have several questions unanswered.

1. Exactly what are those exceptional conditions when these services might be required?
2. If code is being written on *nix systems, or for that matter on Windows also, what is a portable way of clearing the screen, registering key-presses and positioning the cursor at arbitrary locations?

These are the questions, answers to which we explore in the rest of this article. Along the way, we will develop a C++ class which can be used on Unix terminals fairly portably to do all the terminal manipulation. It should work even on Windows, if the appropriate (free) libraries are available for linking.

I chose to answer the second question ahead of the first because at this point I have had enough words and not enough code. I guess it's true for you too. So how would such an implementation look, and how are we going to use it.

The UnixTerminal class and its use

Here is the header file containing the definition of a class called UnixTerminal. This class needs to be instantiated with just two arguments passed to its constructor - the input file descriptor and output file descriptor.


// file: UnixTerminal.hpp
#ifndef __UNIX_TERMINAL__
#define __UNIX_TERMINAL__

#include <boost/shared_ptr.hpp>
#include <string>
#include <exception>


class UnixTerminal
{
public:
enum mode_t { read = 0, write = 1 };
UnixTerminal( int in_filedes = STDIN_FILENO, int out_filedes = STDOUT_FILENO );

bool clear();
int keyPress( bool echo = true );
bool setCursorAt( int x, int y );

int getLines();
int getCols();

friend UnixTerminal& operator << ( UnixTerminal&, const std::string&amp; out ); 

friend UnixTerminal& operator >> ( UnixTerminal&, std::string&amp; in );

private:
int get_screen_measure( const char* measure_name );

struct TermData;
boost::shared_ptr in_, out_;
bool in_eof_;

struct PutcToTerm;
};


struct TermException : std::exception {
TermException ( const char * msg ) throw() : what_(msg)
{}

const char* what() throw()
{
return what_.c_str();
}

~TermException() throw()
{}

private:
std::string what_;
};

#endif /*__UNIX_TERMINAL__*/


A typical use of this class will be in code like the following:

#include "UnixTerminal.hpp"
#include <iostream>

int main()
{
try {
UnixTerminal ut;
std::string s1 = "Yonatan Rabin";

// print message
ut << s1;
// register key-press - without echoing (false)
char ch = ut.keyPress(false);
// clear screen
ut.clear();
std::cout << ch << std::endl;

// position cursor at the middle of the screen
if ( ! ut.setCursorAt( ut.getCols()/2, ut.getLines()/2 ) )
std::cerr << "Could not set cursor position" << std::endl;

// take line input into s2
std::string s2;
ut >> s2;

std::cout << s2 << ": " << s2.length() << std::endl;
}
catch (std::exception &obj) {
std::cout << obj.what();
}

return 0;
}
The ncurses-based implementation

This section will be ready soon.

To throw or not to throw

2006-10-25T17:50:00.000+05:30

Dispelling the myths and misgivings people have about throwing exceptions from constructors

In course of my four years of writing code, I have come across many cases where I write a C++ class that needs to do something fairly non-trivial in its constructor. The single biggest dilemma I have run into in such situations is to decide on what to do if some operation goes horribly wrong inside the constructor and all bets go off as far completing the construction is concerned.

First of all, do we throw an exception from a constructor? Is it valid C++, is it a correct practice, can it be recommended? In all this time, no one gave me an affirmative reply to any of these questions - no one from among my seniors, leads or peers. The correct answer however, to all of the questions posed here, is YES.
- Throwing exceptions from constructors is valid in C++.
- Throwing exceptions from constructors is correct and recommended when needed.

Value-type casts of the new age

2006-10-24T12:13:00.000+05:30

Easy and sensible type conversions of streamable object values / states

Last weekend I was trying to write for myself a small shim-class which will convert between bool and std::string data types. I wanted the conversions to also handle English words like "true", "yes" or "NO" in an intellligent way and convert them to boolean values.

I ended up writing a small set of classes which handle conversions between any two streamable types (in other words any type which can be inserted into an ostream object like cout and extracted from an istream object like cin). This work is not a purely original work - influenced by the semantics of boost::lexical_cast. It also uses a case-insensitive std::basic_string constructing which has been described by Herb Sutter in one of his GotW articles.

It's just that I might just want to use a lexical_cast facility without really bothering to use a whole new library for it (I love boost but if lexical_cast is the only thing I need from its offerings, I'd rather roll out my own, call it egotism if you will).

I have disallowed conversions to pointer types. I reckon the only conversion to a pointer type you will really ever need is to char* and you can manage with conversions std::string and then use c_str() accessor member function. If you want to convert from long to some pointer type use casts provided by the language (static_cast / reinterpret_cast).

I haven't looked at boost::lexical_cast's code and I am certain it will be tighter than mine. That notwithstanding, my code is listed below.

The above code compiles on gcc 2.95 and above. The code does not compile on MSVC 6.0 and I am yet to test it on a later compiler (I have MSVC 7 and I guess it will compile on it).

Here is some stub code to test the above utilities:


// ---- this file is called lexical_cast_test.cpp ----- 

// lexical_cast_stub : 
//

#include <iostream>
#include "conversion.hpp"

int main(int argc, char* argv[])
{
 try {
  std::string val = "52";
  int num = MYUTILS::lexical_cast<int>(val);bool>(val); // expect num to contain 52

  val = "TruE";
  bool b = MYUTILS::lexical_cast<bool>(val); // expect b to contain true

  val = "I am not a number";
  num = MYUTILS::lexical_cast<int>(val); // this should throw bad_lexical_cast
 }
 catch ( std::exception& e )
 {
  std::cout << e.what ( ) << std::endl;
 }

 return 0;
}

This form of usage obviates the need for an elaborate set of conversion functions like atoi which can segfault or the [v]s*printf family of functions, whose use is clumsy.
