Patch for the bjam's build script
by Vaclav Vesely 29 Apr '03

29 Apr '03

When compiling the bjam under MSVC or VC7 tools and the LIB environment variable ends with a backslash, for example: LIB=C:\PROGRA~1\MICROS~3\VC98\LIB\ than the build.bat script fails. I've spend quite a long time with looking for the cause. The attached patch fixes it: Regards, w begin 666 jam_src.patch M26YD97@Z('1O;VQS+V)U:6QD+VIA;5]S<F,O8G5I;&0N8F%T#0H]/3T]/3T] M/3T]/3T]/3T]/3T]/3T]/3T]/3T]/3T]/3T]/3T]/3T]/3T]/3T]/3T]/3T] M/3T]/3T]/3T]/3T]/3T]#0I20U,@9FEL93H@+V-V<W)O;… [View More]W0O8F]O<W0O8F]O M<W0O=&]O;',O8G5I;&0O:F%M7W-R8R]B=6EL9"YB870L=@T*<F5T<FEE=FEN M9R!R979I<VEO;B Q+C$Q#0ID:69F("UU("UR,2XQ,2!B=6EL9"YB870-"BTM M+2!T;V]L<R]B=6EL9"]J86U?<W)C+V)U:6QD+F)A= DR,2!!<'(@,C P,R P M-#HS-CHR.2 M,# P, DQ+C$Q#0HK*RL@=&]O;',O8G5I;&0O:F%M7W-R8R]B M=6EL9"YB870),C@@07!R(#(P,#,@,C,Z-#0Z-3$@+3 P,# -"D!

RE: [Boost-Users] Circular Buffer

I've seen several implementations of things like this come up on the boost mailing list in the past. My impression is a lot of people gave up when confronted with all the different options that would have to be considered to make it through a Boost review.

uBlas - diagonal_matrix
by Patrick Kowalzick 28 Apr '03

28 Apr '03

Dear all, I can use a banded_matrix to represent a diagonal matrix, but while some math for a diagonal matrix is a little bit easier than for a rectangular matrix, it would be nice to have such a type. In my case: I use a SVD A = U * S * V.T to calculate the moore-penrose-inverse A+. Therfore I use A+ = V * S+ * U.T (i do not remember exact, but focus on S+) with S+ as the moore-penrose-inverse of S which is very easy to calculate. but to use something like pinv(S) , do I need a … [View More]

Re: pool_allocator problems on VC7.1 (real rele ase)

Why, BTW, does it have > to use the Singleton pool interface instead of the object pool > interface? The latter, I … [View More]think is what I'm after. I'm going to start with a brief overview of the Boost.Pool interfaces: pool<> (pool.hpp): "The" pool interface. Provides allocation and deallocation of memory. object_pool<> (object_pool.hpp): Restricts access to the pool<> interface. Provides allocation and deallocation of memory for a single object type; and, when destroyed, will call the destructor for any non-deallocated objects allocated from that object_pool. singleton_pool<> (singleton_pool.hpp): Provides access to the pool<> interface as a singleton, distinguished mainly by size of the memory allocations and a tag. pool_allocator<> (pool_alloc.hpp): Restricts access to the singleton_pool<> interface. Provides a Standard-compliant Allocator interface. To answer the specific questions: 1) The pool_allocator<> (and fast_pool_allocator<>) can be relatively easily extended to use other tags for the singleton_pool<> interface underlying them - pass an additional template parameter (after the UserAllocator parameter), defaulting to the currently-used tag. This is a good idea, and I'll put it in when I can. 2) pool_allocator<> uses the singleton_pool<> interface instead of the object_pool<> interface for the following reasons: A) Standard Allocators only handle the allocation and deallocation of memory, and do not deal with actual object types [+]. The intent of object_pool<> is to cleanly call destructors for objects that were never deallocated. Such an action: 1) is unneeded (since all containers should free whatever memory they allocate, and destroy any objects they construct), and 2) would cause the Allocator to get into construction/destruction semantics, which is contrary to the Standard Allocator concept. B) Standard-compliant Allocators that can be used with STL-provided containers must be stateless. This requires an underlying singleton interface. Encapsulating a non-singleton interface within the Allocator, or even sharing one with the handle/body idiom does not satisfy the stateless requirement. [+] The object-related Allocator requirements (construct()/destroy()) do not have anything to do with allocation/deallocation, and are generally considered to be a useless overspecification. Please let me know if I haven't been clear enough - I've been a little lacking in sleep lately ;) -Steve [View Less]

MP3 and C++

Hi, I'm working on a project for the university and I'm looking for some C++ library or application that could help me. My goal is to extract some kind of information related to the spectra of a signal coded in MP3. I'm looking for a spectrum analyzer that localizes peaks in the power spectrum (better if it works on a user-specified band) and allows the detection of the temporal occurence of each peak and its intensity. I also need to retrieve some sample of frequency components (or the … [View More]
