[boost] Bjam help
If I have a rule: exe browser : structureparser.cpp tagreader.cpp ; How do I then copy the file that was created above somewhere else? I tried to get "InstallBin" or "InstallInto" to work but I couldn't grock it. I tried this: InstallBin $(PROJECT_ROOT)/tools/browser/bin/browser.app/Contents/MacOS : $(PROJECT_ROOT)/tools/browser/bin/browser/darwin/debug/runtime-link- dynamic/browser ; InstallBin $(PROJECT_ROOT)/tools/browser/bin/browser.app/Contents/MacOS : browser ; etc. Basically I want to copy the exe made in the first rule to another place whenever it's built.

Re: [boost] Build help for OS X
FWIW: I am using gcc 3.3.1 compiled from scratch with sources from gcc.gnu.org under OS X. This works with full optimization (gcc 3.3 did not). I am using gcc 3.1 which is the current version with the development tools that I have on my Mac OS X. It's good to know what I have in store :-) I didn't see your other messages, but I hope this is relevant: I had serious trouble with multiple initializations of a static variable in the Boost.Python library. Somehow I got it to work after hours of trial-and-error. See boost/libs/python/src/converter/registry.cpp, BOOST_PYTHON_CONVERTER_REGISTRY_APPLE_MACH_WORKAROUND. It could be that the std::cout << std::flush trick is the main trick, I am not sure, I only know it works the way you see it.

[boost] feed_args.hpp bug (and patch)
I have found a bug in boost/format/feed_args.hpp.
The simple declaration of a static variable in a header like this:
static int x;
Is "allowed" in GCC, but in darwin, when you try to compile this code
into a "dll" (dynamic-linking), then link using ld, ld will complain
about "common symbols not allowed with MH_DYLIB output format". This
may also be the general case with all platforms, but I haven't been
able to test this.
The correct solution for the above case is, in all headers use:
extern int x;
And in a single place in the implementation:
int x = 0;
Of course the code in feed_args.hpp doesn't even really NEED a global
variable, so as a solution (rather than try to introduce the above
complicated change just for one platform), I propose that we change the
code:
static const std::basic_string emptyStr;
To:
const std::basic_string emptyStr = "";
Which basically does exactly the same thing.
Here is my patch to feed_args.hpp:

[boost] Build help for OS X
I managed to get my stuff built using all shared libraries on OS X, but I came across the following problems: - I had to hack "boost/format/feedargs.hpp" to remove the static variable (I have explained in other posts why). - I am going to work around this by only having a single include point for "format.hpp", but it will limit my further use of this. - I sent a message earlier about changing this code so that is does something a lot simpler than it does, and it fixes my problem. Any thoughts about that? - I had to turn off optimization and inlines for the release build because I was getting a bunch of "non-virtual thunk" errors in the link. - I will test with the latest build from Apple to see if this goes away, since when I googled I received lot's of "this is a compiler bug, turn off optimization" messages. But in the meantime, rather than needing to hack "darwin-tools.jam" to turn off inlining/optimization, how do you change these for the default build? I tried this in my Jamfile: dll cppxmlobjlib : $(XMLOBJ_PATH)/$(CPP_SOURCES).cpp ../libs/cpppersistxmllib ../libs/cpppersistlib ../libs/cppreflectlib : $(BOOST_ROOT) expat off off : debug release ; But it gives me a warning saying that "off" is not compatible with full. How do you override those defaults?

[boost] Global vars
Well,
I've tried to work through the solutions to:
ld: common symbols not allowed with MH_DYLIB output format
Which are basically "-fno-common" on the compile line of each file, but
apart from the fact that tihs doesn't actually work in this case (we
still get the error), it's not really a very good idea.
Does anybody have any suggestions for working around this code:
namespace boost {
namespace io {
namespace detail {
namespace {
template inline
void empty_buf(BOOST_IO_STD basic_ostringstream & os) {
static const std::basic_string emptyStr;
os.str(emptyStr);
}
};};};};
The correct thing to do with this code (for all platforms) is to not
rely on the global variable "common" stuff (which is new to me, and
seems a bit of a hack), but actually do this code correctly, which
means removing the global variable.
What problem is the code above trying to solve?
If i just do this (which i have done to get my stuff working), there
seems to be no prob:
#ifdef MACHACK
template inline
void empty_buf(BOOST_IO_STD basic_ostringstream & os) {
extern const std::basic_string emptyStr;
os.str(emptyStr);
}
#else
#define empty_buf(_os_) (_os_).str("");
#endif
Wouldn't the above two lines achieve basically the same thing (although
I know we hate macros, but since "empty_buf" is only actually used 3
times in the entire project, could all of the:
empty_buf(oss);
be replaced with:
oss.str("");
This would save a whole lot of grief and eliminate this fairly ugly
global variable.
Comments?

You can see this is a bit weird because the names are mangled to
something completely different, but the linker says something about
"common" problems. Does anybody know what this is about?
Maybe the problem is that the symbols should really be common but are
given two completely different names, since they are compiled in too
different units? Not sure.

Re: [boost] xml library
I think that what is still missing in Boost is a library for reading and writing XML files. I have been using expat for a while, and wrapping it in C++ classes. It's a very capable parser and supports lot's of stuff. My parser stuff is just done with a switch statement (since it's event driven), but it would be nice if you could use expat, but then "register" your element "handlers" to get called. This would be a cool design. I don't think I could actually use the "iterator" design that you have, since I need to handle the nesting of tags, so I need to know when I am started and finished a tag. I also need to know the normal CDATA or comments that just came through. Is this possible with the iterator idea? I also have a bunch of code for wrapping expat, but it's pretty simple.

Re: [boost] Re: XMLUI (was Re: Re: UI++)
There's more to it than just creating something that can render UI elements from XML stream. XMLUI is a lot more than this. For one thing it's optimized for animation (sort of like flash) so that interfaces are purely widgetless (as I mentioned earlier). XUL (which is actually a language, you could implement an XUL player using XMLUI) lacks a lot of basic concepts necessary to support the types of UI's that XMLUI can do. To be truly successful you need a UI editor that can generate the XML stream. And creating such an editor is probably less than trivial. Just like XUL, the XMLUI Editor uses XMLUI, so each time you add a new component you also get to have it in the GUI. that part of it pretty much exists, but running on Windows in a "non open source" capacity. So I think it would be better to focus on one goal rather than multiple. I think timing will be more critical now than creating alternatives. My current goal is to take a large body of work that I have built over many years and make it available as an open source project. The reason i thought it might be interesting for the Boost group was that in moving it to OSS I was investing in using Boost for most of the code. I don't really want to go in to too much of an argument on this list about the difference between XUL and XMLUI. I have a ways to go before XMLUI is open source anyway, so it's all academic anyway. At some point I'll create a project I just wanted to let the list know that I was working on it. - Paul Hamilton pHamtec P/L - Software Makers http://www.phamtec.com/ mailto:[EMAIL PROTECTED] The information transmitted is intended only for the person or entity to which it is addressed and may contain confidential and/or privileged material.

[boost] boost::io::detail::empty_buf problem with shared libs
This gives me problems:
template inline
void empty_buf(BOOST_IO_STD basic_ostringstream & os) {
static const std::basic_string emptyStr;
os.str(emptyStr);
}
When I use something that includes this in two different dll's, and
then try to link them into another exe (or dll), I get a problem with
duplicate symbols.
It's usually a bad idea to declare a global variable as part of a
library, without specifying some way of providing the actual definition
of it a single time.
What is the work around apart from wrapping all of the boost functions
in another library?
I'm working on OS X, so maybe it's specific to that platform.

Although it's great as a tool for creating "Browser like" applications, especially ones that integrate Mozilla. One of the major problems with it is it's lack of "independence" from it's primary application that it is based on - Mozilla.

[boost] Re: UI++
I am currently porting something called "XMLUI" to use boost/bjam etc. The general background of XMLUI is based on the work we did at mBED for a "flash-like" animation system (although it predated flash). This project is the culmination of a number of years of design of "widget-less" UI systems that I have been undertaking. What XMLUI is now: - XML based description language for UI's (windows, panes, buttons etc). - Rendering engine for the above (only on windows at the moment, and not GPL or using boost). - Dynamic loading system (just DLL's on windows). - Tools for developing XMLUI are written in XMLUI. - written using C++ (VC at the moment). - heavy use of patterns and STL. I presented a white-paper on XMLUI at an XML conference last year (which I can send to people who want it. It's only a 170K PDF), and the project has been used commercially to build a number of systems. So where am I at? A complete UI system may involve a complex class hierarchy of maybe 200 to 300 objects. Each of these objects needs to interact in the following ways: - settable and gettable members directly in the UI (so that a slider can modify a text field for example). - observer pattern in heavy use so that a button can dim based on the value of another object's field (for state maintaining), and so that a slider can update a text field. - each object persists to and from XML files (and complete hierarchies of objects need to do this). So to support this, from the start you need: - A "tangle" tool which can read a large object schema and build C++ classes for: - the visitor patterns so that members can be set/get. - the observer pattern. - the prototype pattern (for object inheritance and persistance). - the composite pattern so that one object can contain lists (vectors) of other objects and references to other objects. - A schema which describes the following types of objects: - panes which represent the different types of UI elements. - commands which encapsulate the actions for the buttons etc (and for the undo system). - enablers and pipes for moving data around between objects. - some type of expression language. - generators for filling panes with data. What I have done using boost: - A general persistence scheme called cpppersist which is general, but I have written an XML persister. - A general reflection scheme called cppreflect which allows members of objects to be set/get via strings (and found etc). - A base object for all "XML persisted/reflectable" objects called xmlobj which combines the above two things. These are almost ready to go up (on sourceforge probably), I just need to write a few more unit tests. What I am working on right now: - a tangle/weave literate programming system using xmlobj's called cppliterate which I can use to build all of the classes, create the Jamfiles etc. I am a couple of weeks of work away from finishing this off. I need to integrate tangle into boost's build system, and I need to build a weave tool (it really isn't needed since I get around it now by having tangle build "doxygen friendly" source files, and then run doxygen on them. But a REAL weave will be necessary for user documentation etc). Naturally weave and tangle will be built using weave and tangle :-) So it's an interesting if not recursive exercise to build (like, how much of tangle do you need to have written before it can start tangling itself?). When I've finished cppliterate I'll let you guys know, but of course this still isn't anything to do with UI's, but it would be useful for others who need to do large scale cpp development. This will be released the same as boost is (using the same build system), so it might be cool to put it into boost at some point once it's proven useful. Once this is done, you could use it to build a description system for a widget library, which is a necessary thing. You could probably write an object-widget mapper in tangle to generate the WxWindows/QT/MFC stubs directly which would save time. Then it's a case of taking my existing schemas that I have for XMLUI, creating all the objects and then porting all of the code currently running on windows to this new system. This is probably a good 6 months away, but it will happen this year, and it will be free (probably GPL). It will probably only be windows/Mac OS X available, but a port to X would be simple.

Good points Dave. it's not really meant to be evaluated with the idea that it will be incorporated into Boost, since it's extremely intrusive and not really conducive to adding to projects. The announcement was really just a heads up for the list that this thing exists, and it might be useful for some projects where you read and write data from XML files. I have written this as part of another project, and thought that I would go "free" with it straight away, because I looked around myself for XML persistence and couldn't really find anything of use to me (they all involved some type of preprocessing which I hate. at least this thing you can just bolt on to any class from the outside). This scheme also uses "pure" patterns like Visitor, Abstract factory, Composite to do it's stuff. There are two small parts of this called "cppreflect" and "cpppersist" which would probably make nice additions to Boost, since they are very small, simple and general, but I'm really busy at the moment getting some other stuff going and don't really have time to push this. I'd really rather get a project written using this stuff as a kind of "body of work" using it rather than try to push it on the group at such an early stage. Thank's for looking at it though!

[boost] Building header files with bjam
I have a need to generate header files which are then subsequently used
in a source file and built.
If i have a file called "xxx.y", which is used as an input to a program
to generate "xxx.hpp", and "xxx.hpp" is included in "xxx.cpp" I should
(I thought) be able to do something like this:
rule Tangle
{
DEPENDS $(<) : $(>) ;
}
actions Tangle
{
tanglemyfile $(<) $(>)
}
Tangle xxx.hpp : xxx.y ;
CPP_SOURCES = xxx.cpp ;
lib mylib : $(CPP_SOURCES).cpp
: $(PROJECT_ROOT) $(BOOST_ROOT)
: debug release
;
But when I try all of this in my jamfile, as much as I touch xxx.y,
xxx.hpp is never being asked to rebuild. basically the "actions" is
never executed.
What's the right way to do this?
Paul.

Please see the tools/build/index.html page in your Boost distribution. Definitely read ALL of the documentation. after building bjam and jam, you will need to track the binaries down and then copy them somewhere on your executable path. I built for OSX, and I just cp'd bjam and jam into /usr/bin (you could just drag them in also). ----- Paul Hamilton pHamtec P/L - Software Makers http://www.phamtec.com/ mailto:[EMAIL PROTECTED] The information transmitted is intended only for the person or entity to which it is addressed and may contain confidential and/or privileged material.
