Help setting up boost for vc7
by Chris Ward 13 Jun '05

13 Jun '05

I have MS VC++ 7.1 installed to the default location (C:\Program Files\Microsoft Visual Studio .NET 2003), O/S WinXPSP2 However, when I run Build.bat from the command line, it returns " \Utilities\Bin\x86 was unexpected at this time." This occurs if I let the script auto-detect and also if I specify the toolset as vc7. Can someone please steer me in the right direction? regards Chris Ward

[thread] null_mutex
by Jody Hagins 13 Jun '05

13 Jun '05

Looking through the archives, a number of requests have been made for a null_mutex, but none exist. Probably because of the chance of trouble when used in conjunction with a condition variable. However, I have need for one (and it looks like others do as well, with a simple google search). Attached, are two files, each representing the output of running cvs diff on my local CVS repository (which is the official 1.32 release). diff.txt is the result of running: cvs -q diff diff-c.txt is the result of running: cvs -q diff -c I'd appreciate any feedback, and also consideration to add something like this to Boost.Thread.

After reviewing your mail and bjam\bulid a bit more- I think I am starting to "see it" (Bjam\Build). My guess is, whatever the final solution ends up being will be something connected at the lower levels to either bjam or build. Also my example was "weak". :)- It's probably easier to talk about specific problems once I have identified the actual CAUSES of (to start with) my problems. > > > * share the tool with the rest of the community. > > * watch the users list for folks having build problems- offer to help > > them- use the tool as a proxy for figuring out their problems- in this > > way the tool evolves the ability to solve the common problems.

David, belated response- sorry for the disconnection in time. Let me say a (HUGE) THANK YOU for writing up below, it really has my gears turning. I have been reviewing your mail, and reviewing the boost build docs contemplating the issues you raised daily since your post. (thinking maybe if I "sleep on it" a solution will appear). Where I am at: * I see what you are saying * I am left still feeling like this is a solvable problem * Yes, you are right there is no clear and easy path that we can see right now * Before I die (grin- I am on a mission :) ), I will do something to enable debugging of build problems. There IS a solution, one just have to think about it long enough until they find it :) What I am thinking right now: * I would appear to have more bjam\boost build problems than most people :) * I need to be careful, because I have a tendency to try to do too many things at once. (right now I am working to finish a preview of a potential boost library). * I need to remember that trying to think about this from the top down, and "organically" growing a solution are two different things. My plan (to address this organically): * First off finish my other work :) * then spend the time to really get my head wrapped around bjam\boost build * debug my own build problems- and make careful notes on "what the problems were" * Post-Mortem- build a tool that WOULD have shown me the problem immediately. I.e. (weak example:) if my bjam.exe is the wrong version- then the tool would simply report the version * share the tool with the rest of the community. * watch the users list for folks having build problems- offer to help them- use the tool as a proxy for figuring out their problems- in this way the tool evolves the ability to solve the common problems. OR it becomes clearly proven that this is not possible. (my gut tells me it IS possible) * I am going to save this mail off, and then when I have learned a few things by doing above, I may "re-open" this thread with what I have learned. Thank you David for a very useful conversation. :) Brian > -----Original Message----- > From: boost-bounces(a)lists.boost.org [mailto:boost-bounces@lists.boost.org] > On Behalf Of David Abrahams > Sent: Monday, June 06, 2005 5:18 AM > To: boost(a)lists.boost.org > Subject: [boost] Re: Boost Build Env Checker (was RE: Re: > CustomerFriendlier Boost Installation) > > "Brian Braatz" <brianb(a)rmtg.com> writes: > > > boost-bounces(a)lists.boost.org wrote: > >> On Behalf Of David Abrahams > >> Sent: Tuesday, May 31, 2005 7:08 AM > >> To: boost(a)lists.boost.org > >> Subject: [boost] Re: Customer Friendlier Boost Installation > >> > >> "Brian Braatz" <brianb(a)rmtg.com> writes: > >> > >> > HAVING said that here is the suggestion, reformed: > >> > > >> > Boostenvcheck.exe become s a program which LISTS the dependencies for > >> > your configuration. > >> > >> Can you show an example of what that output might look like?

[typeof][result_of] Separated at Birth?
by David Abrahams 12 Jun '05

12 Jun '05

It seems to me that when BOOST_TYPEOF becomes available, boost::result_of should use it in its default implementation, something like: template <class F, class A> struct result_of<F(A)> { typedef typename BOOST_TYPEOF(make<F>() ( make<A>() ) ) type; }; Is that in the plan? -- Dave Abrahams Boost Consulting www.boost-consulting.com

Patch for ifstream_line_iterator_test regression failure
by Janusz Piwowarski 12 Jun '05

12 Jun '05

Hello all, I'm attaching a patch for ifstream_line_iterator_test regression failure. It's probably gcc bug (i test it for mingw 3.4.2, but i noticed same error in linux tests), because compiler generates copy constructor for temporary variables and never use it (for those who want to test it in linux environment i'm attaching minimal example). Regards, Janusz
