Boost 1.32.0 FreeBSD port ready -- please review patches
by Simon Barner 08 Jan '05

08 Jan '05

Hello Boosters, I am maintaining the FreeBSD port of Boost, and I'd like to ask you to review the changes I had to make in order to get things to work and possibly to merge some of them into your CVS. First some information about Boost on the FreeBSD platform... There are two supported platforms: - FreeBSD 5.3, with gcc 3.4.2, wchar support - FreeBSD 4.10/11 with gcc 2.95.4, no wchar support, build with stlport 4.6.2 and spirit 1.6.2 to overcome compiler insufficiencies. Sprit 1.6.2 is obtained form http://spirit.sf.net, so I wounder if you guys can do anything about it, but it would be great to have tarball that uses UN*X encoded source files (i.e. without CRLF as line separator). If you don't have a FreeBSD installation, you can find the port skeleton (which is basically a set of patches and scripts needed to build a software package) here: http://www.freebsd.org/cgi/cvsweb.cgi/ports/devel/boost/ I will now present all of the patches I made (please don't beat me if I did something ugly or something which might hurt a Boost developer's feelings ;-) The links above a particular patch enable you to download it from FreeBSD's CVS. After that I'll describe briefly the intention of that patch, which is quoted below. One of the intentions of this posting is to check whether I did my changes at the right places, or if the are crude hacks (I suspect some of my changes to the configuration files fall into this category). A total of 8 patches follows, but don't be afraid, most of it is FreeBSD specific, but I wonder if some patches could be merged into Boost's CVS. http://www.freebsd.org/cgi/cvsweb.cgi/~checkout~/ports/devel/boost/files/pa… This patch enables wchar support on FreeBSD 5 and disables it on older versions.

OS X Link Problems
by Alan 08 Jan '05

08 Jan '05

I built boost thus: bjam "-sTOOLS=darwin" -sBUILD="debug release <runtime-link>static/dynamic" After hacking around the xml_grammar.cpp problems, I get the link errors where the following functions cannot be found. (Removed a lot of extra stuff to try and display only the library and missing function. If you'd like to see all 183 lines that is possible.) I'm wondering if some test functions that are not meant to be in the library are referenced by something included in the library. darwin-Link-DyLib-action bin/boost/libs/test/build/libboost_prg_exec_monitor.dylib/darwin/debug/runtime-link-static/shared-linkable-true/libboost_prg_exec_monitor-sd-1_32.dylib ld: Undefined symbols: cpp_main(int, char**) darwin-Link-DyLib-action bin/boost/libs/test/build/libboost_prg_exec_monitor.dylib/darwin/debug/shared-linkable-true/libboost_prg_exec_monitor-d-1_32.dylib ld: Undefined symbols: cpp_main(int, char**) darwin-Link-DyLib-action bin/boost/libs/test/build/libboost_prg_exec_monitor.dylib/darwin/debug/shared-linkable-true/libboost_prg_exec_monitor-d-1_32.dylib ld: Undefined symbols: cpp_main(int, char**) darwin-Link-DyLib-action bin/boost/libs/test/build/libboost_prg_exec_monitor.dylib/darwin/release/runtime-link-static/shared-linkable-true/libboost_prg_exec_monitor-s-1_32.dylibld: Undefined symbols:cpp_main(int, char**) darwin-Link-DyLib-action bin/boost/libs/test/build/libboost_prg_exec_monitor.dylib/darwin/release/shared-linkable-true/libboost_prg_exec_monitor-1_32.dylib ld: Undefined symbols: cpp_main(int, char**) darwin-Link-DyLib-action bin/boost/libs/test/build/libboost_test_exec_monitor.dylib/darwin/debug/runtime-link-static/shared-linkable-true/libboost_test_exec_monitor-sd-1_32.dylibld: Undefined symbols:test_main(int, char**) darwin-Link-DyLib-action bin/boost/libs/test/build/libboost_test_exec_monitor.dylib/darwin/debug/shared-linkable-true/libboost_test_exec_monitor-d-1_32.dylibld: Undefined symbols:test_main(int, char**) darwin-Link-DyLib-action bin/boost/libs/test/build/libboost_test_exec_monitor.dylib/darwin/release/shared-linkable-true/libboost_test_exec_monitor-1_32.dylibld: Undefined symbols:test_main(int, char**) darwin-Link-DyLib-action bin/boost/libs/test/build/libboost_unit_test_framework.dylib/darwin/debug/runtime-link-static/shared-linkable-true/libboost_unit_test_framework-sd-1_32.dylibld: Undefined symbols:init_unit_test_suite(int, char**) -- Alan Gutierrez - alan(a)engrm.com

Any interest in a library for supporting program reuse?
by christopher diggins 08 Jan '05

08 Jan '05

Hi all, the compulsive coder here again, I've just written in a working prototype of a library for writing C++ programs which can be treated in C++ code like Unix filters, i.e. redirected to and from streams, and other programs. For instance: fstream f("c:\\tmp.txt"); stringstream s; HelloWorldProgram() > f > UpperCaseProgram() > s; Is there any interest in this kind of library, for boost? I am using it for writing test and demonstration programs of libraries, but I think it has a lot of other uses. The source code and a more detailed explanation is at http://www.codeproject.com/useritems/program-objects.asp Christopher Diggins http://www.cdiggins.com http://www.heron-language.com

What is STRANGE is that "sometimes" bind(Base::ReturnAString) works ironically, I have about 40 calls that use that syntax that work just fine. I noticed in the docs, when you have a inline functor, the docs use > bind(Base::ReturnAString); But when you have something that was not inline (??) you use: > bind(&Base::ReturnAString); I was never clear on when you and when you do NOT use the "&" with the bind() syntax..... I will convert everything in my "real code" to using the & always. Question: Does anyone know when you should and should not use the & in a bind call? Or is this is compile time checking hole that exists due to the mechanisms bind relies upon? OR Am I a complete idiot? (I find it important to always hold open this option as a possibility in everything)

Bizarre Lambda bind() problem with Base class types

With the following code, If you UNCOMMENT the "// public : Base" line, you get compiler errors (????) I have tested this with MS VC 7.1 against both 1.31 and 1.32 versions of boost with the same results. Any idea why this is happening? (full sample code I wrote is attached) using namespace boost::lambda; namespace Tests { class Base { public: std::string ReturnAString() { std::cout << "hi"; } }; class Derived // : public Base // UNCOMMENT ME to see the errors { public: void Func() { bind(Base::ReturnAString,_1); } }; }; // namespace Tests My Compiler errors are this: ------ Build started: Project: Test_LambdaProblem, Configuration: Debug Win32 ------ Compiling...

thread lib patch
by François Dumont 08 Jan '05

08 Jan '05

Using MSVC6, STLport 5.0 beta, february 2003 SDK under Windows XP I failed to build thread library because of a missing include. In read_write_mutex.cpp, tchar.h contains _sntprintf macro definition but not the functions definition hidden behind this macro. Those are in stdio.h. Maybe this file was included in a previous version of STLport but it is not anymore. I am also surprised that those files are included if BOOST_HAS_WINTHREADS is defined and symbos coming from them are used if WINVER is defined. Isn't there a little inconsistency? Bests

[gui] Shoulders of Giants
by Alan Gutierrez 08 Jan '05

08 Jan '05

I'd like to take some time and study what has gone before. If I think of a list of successful windowing libraries the following come to mind. http://www.torjo.com/win32gui/ http://www.wxwindows.org/ http://java.sun.com/docs/books/tutorial/uiswing/ http://www.tcl.tk/ http://www.trolltech.com/ http://developer.apple.com/cocoa/ I plan on having the documentation for these windowing libraries on hand, as well as the source code, where available. I've advocated the use of a CSS layout component to render the View-Controller aspect in fashion that is cross-platform and i18n. This is my pet, so I'm interested in reading through existing web browser work. http://mozilla.org/ http://www.konqueror.org/features/browser.php http://developer.apple.com/darwin/projects/webcore/ https://xhtmlrenderer.dev.java.net/ I'm sharing these thoughts to see if anyone has must see, must consider projects to suggest. Maybe by looking at these lists someone can tell me if I'm totally missing a concept. -- Alan Gutierrez - alan(a)engrm.com

Property
by Jason Hise 07 Jan '05

07 Jan '05

The following is a class to emulate C# properties using C++: www.ezequal.com/chaos/libs/property.h example code: template < typename T > class Coord { private: T x, y; T get_X ( ) const { return x; } T get_Y ( ) const { return y; } void set_X ( const T & value ) { x = value; } void set_Y ( const T & value ) { y = value; } public: utils::GetSetProperty < Coord < T >, T > X; utils::GetSetProperty < Coord < T >, T > Y; Coord ( ) : X ( this, get_X, set_X ), Y ( this, get_X, set_X ) { } Coord ( T X, T Y ) : X ( this, get_X, set_X ), Y ( this, get_X, set_X ) { this->X = X; this->Y = Y; } }; The compiler appears to optimize out any calls between the property's use and the get/set functions. Any thoughts or suggestions for improvement? -Jason

program objects and iostreams filters
by christopher diggins 07 Jan '05

07 Jan '05

There has been some questions posed to me as to the difference between Jonathan's iostreams library filter concept ( http://home.comcast.net/~jturkanis/iostreams/libs/iostreams/doc/ ). The iostreams library and it is the correct choice if you are writing a relatively simple filter, but writing an even more sophisticated program as an iostreams filter, is non-trivial. For instance the following code would require some significant rewriting in order to make it a single filter object. public Avg : Program { virtual void Main() { double dSum = 0; int nCnt = 0; while (!cin.eof()) { double d; std::cin >> d; dSum += d; } std::cout << dSum << std::endl; } } This is primarily because a filter involves a series of calls to a single function such as put or get (see: http://home.comcast.net/~jturkanis/iostreams/libs/iostreams/doc/tutorial.ht… ) . The point of the Program class is that I want to be able to write a C++ programs as naturally as possible, and still redirect it, or chain them together simply. The above program can be redirected to a stream, or to another file by simply writing: Avg() > fstream("c:\\tmp.txt"); Just so I am clear. I am not at all suggesting that what I propose is replacement for any part of the iostream library. It is designed as an alternative to using main().
