[program_options] typo in doc
by Matt Hurd 18 Oct '05

18 Oct '05

http://www.boost.org/doc/html/program_options/overview.html#id1247613 has the line pd.add("output-file", 2).add_optional("input-file", -1); which is not supported. Only void add(...) exists. pd.add("output-file", 2) pd.add("input-file", -1); would be correct I think. matt.

I think what I'll want to do, for a first cut, is always produce 64-bit literals for 64-bit capable compilers. I'm going to wait until after the review period to start on fixing the 64-bit support. Since I don't have a local 64-bit compiler I'll be working blind and my first few efforts will be dead wrong. At an initial glance it looks like 64-bit support should be achievable without heroic efforts. But it certainly won't come along for free. Thanks again Reece. Scott Schurr

Futures
by Thorsten Schuett 17 Oct '05

17 Oct '05

Hi, I uploaded a new version of the futures library to the boost vault. http://tinyurl.com/9lws4 Just a remainder, futures execute functions in separate threads. Later the future can be used to retrieve the result of the function. The major change is the addition of iterators over futures. Last time some people complained during the discussion that there were operators missing which they needed for combining futures. So instead of adding more operators I added iterators which can be used to implement almost any combination of futures. simple_future<int> f1 = bind(fac, 4); simple_future<int> f1 = bind(fac, 6); simple_future<int> f1 = bind(fac, 8); future<int> f = f1 || f2 || f3; for(future<int>::iterator it = f.begin(); f.end() != it; ++it){ cout << *it << endl; // prints fac(4), fac(6) and fac(8) if(*it > XXX) break; } That way, you can wait for as many futures to finish as you want and you can decide while waiting, for how many you want to wait. All feedback is appreciated. Thanks, Thorsten

I've seen errors like this that were removed by changing all of the literals in the file to unsigned by appending a 'u'. I suspect that there's a problem with the size of the literals on the 64-bit compilers. Does one declare a 64-bit literal by appending a double L ('LL')? If so, then I'll give that a try. Thanks.

I have attempted fixes for these errors. 1. I removed the BOOST_WORKAROUND, and made what was the BOOST_WORKAROUND the only behavior. 2. I removed trailing commas at the end of three enum definitions. 3. I removed the assignment operator definition from the protected section. I am hoping that with these changes the template will survive appropriately picky compilers with no warnings or errors. Unfortunately I can't verify my changes because my compilers are passing both the old and new versions of the template. I have uploaded the new version of the zip to the sandbox: http://boost-consulting.com/vault/ under the name binary_int. I hope that I actually improved the template :-). I'm sure I'll hear. Thanks. And thanks for your efforts on the review. Scott Schurr

[quickbook] chapters and sections
by Joel de Guzman 17 Oct '05

17 Oct '05

Hi, I just realized that quickbook does not have chapters! Looking at the boostbook.xml output, I see many chapters. In quickbook, a whole qbk is regarded as one whole chapter. I was wondering why we were generating a 2 level deep hierarchy of html pages. Deeper than that, the sub- sections are placed within it's parent section's html page. With chapters, we have more structure. Fortunately, this is easy to fix. I can easily add a [chapter title], [endchapter] markup built on top of the section mechanism. Actually, I can even do this without necessitating syntax change by simply assuming the outermost [section] as chapters. Your thoughts? Regards, -- Joel de Guzman http://www.boost-consulting.com http://spirit.sf.net

select_stdlib_config.hpp patch breaks gcc 2.96 build (Redhat 7.3)
by Ralf W. Grosse-Kunstleve 16 Oct '05

16 Oct '05

The select_stdlib_config.hpp patch below from 10/15/2005 breaks our Redhat 7.3 build of Boost.Python. An example error message is also shown below. Could this be fixed with BOOST_NO_LIMITS guards or something similar? Thanks!

[1.33.1] [Thread] read_write_mutex
by Douglas Gregor 16 Oct '05

16 Oct '05

A while back, John Maddock pointed out that we have serious problems with read_write_mutex: http://lists.boost.org/Archives/boost/2005/09/93180.php Have we addressed these problems to everyone's satisfaction? If so, great; if not, we need to remove read_write_mutex from the RC_1_33_0 branch immediately. Doug
