Problem compiling Windows C++ code wit regex
by arno.schaefer＠sqs.de 05 Oct '04

05 Oct '04

Hi all, I try to compile some older C++ Code with your RegEx class and got in some source code problems with some ambiguity I believe between the std and the global namespace. I followed the include hierarchie starting from "boost/regex.h" down to "boost\config\stdlib\dinkumware.hpp" and here was my first problem, why this stdlib implementation was selected, I don't think, that this is the normal implementation for "VC++ 6.0 SP6" what I am using!? The errors I got are located in some windows system header and look like this only in one source file: : d:\programme\microsoft visual studio\vc98\include\objidl.h(9901) : error C2668: 'memset' : ambiguous call to overloaded function d:\programme\microsoft visual studio\vc98\include\objbase.h(435) : error C2668: 'memcmp' : ambiguous call to overloaded function d:\programme\microsoft visual studio\vc98\include\objbase.h(459) : error C2668: 'memcmp' : ambiguous call to overloaded function Error executing cl.exe. Any idea what kind of define can cause this problem? I visit every included headerfile and look also in the expanded preprocessor code (*.i file) and didn't see exactly what happend, so have somebody an idea? Thanks for your help Arno

RE: [Boost-users] boost install with gentoo issue?
by Foster, Gareth 05 Oct '04

I used boost via the fedora rpms, and that was okay, maybe that will help you narrow down the problem (ie maybe it's a gentoo thing rather than a packaged boost thing). Cheers mate Gaz -----Original Message----- From: boost-users-bounces(a)lists.boost.org [mailto:boost-users-bounces@lists.boost.org] On Behalf Of dave(a)superelite.net Sent: 05 October 2004 04:59 To: boost-users(a)lists.boost.org Subject: [Boost-users] boost install with gentoo issue? Well, more likely my mistake, ive been up awhile.. I installed the boost libs onto my gentoo machine with emerge. I then added -lboost_regex to my linker flags..thats it. When I run my app, it hangs, I think when waiting on pulling data of off a UDP socket. Though I cant tell, I'm about to crash and its been one of those days. But I do know everything is back to normal when I take -lboost_regex out of the flags again. I know I'm awfully vague due to lazy/tiredness, but does this ring a bell with anyone? I've installed boost the traditional way (bjam) on other linux distros before without any issue, but ive never tried emerge before. I dont know if this has something to do with it, or i am somehow missing something really obvious..

C++ Parsing - oops
by Foster, Gareth 03 Oct '04

03 Oct '04

Hello John, Joel, I didn't mean to knock your work with that last email John, it might have come across badly, it was meant more as a compliment to spirit and a reference to the fact that it 'appears' to fit the bill for what I want to do better, not to bash regex, I like regex too. For the record it needn't be 'perfect' indexing of the C++ code, I don't mind if I get two hits for the same classname for example. I used regex for a tool to index the C++ and C files themselves, so I could quickly search for file names using regular expressions, it works great! So thank you both, no offence caused I hope. So, will spirit be the best way then? Glad to hear its already a part of boost btw, congratulations mate. Cheers!

It depends what you want to do: if you want to use a "real" C++ parser then you will also have to preprocess the code (including the includes) and then parse the code. In theory this gives you a "perfect" result, but only if you know what include paths to use, and what predefined macros should be set (think about conditional code blocks). Regexes on the other hand, don't require you to preprocess the code, but can get confused by macros and the like. So you have to choose the way that best meets your expectations, and live with the defects either which way ;-) To solve your problem BTW, why not scan through the file for line starts (keeping count obviously!), and at each line start see if it's also the start of the regex you are interested in (one that matches a class definition for example), if you do this don't forget to either: prefix your expression with \A or Pass the match_continuous flag to regex_search, Either will anchor the search at the start of the line you are checking, and prevent the whole text being searched.

Re: Boost:regex and C++ Parsing - Spirit!
by Foster, Gareth 03 Oct '04

03 Oct '04

Wow, I just read through the 1st few pages of the spirit docs, and I can safely say, that is as close to naked women as C++ code will ever be, its such a sexy idea. One library, and you can parse any sort of config file, code or anything! Amazing. Well, any lingering desire to use regex for my pet project has now left the building, I can't wait to have a play with spirit. When will it be a part of boost? Is it worth installing it seperately (I'd hate to do that and have a new boost appear the day after). Also, reading this made up my mind that I should get a nice magazine about STL and C++ matters, can anyone recommend one (UK based preferable, but all sugestions welcome). Interetsing stuff, thank you all! Gaz

boost::multi_array class member

Hi to all. Sorry for my English. I'm trying to use a boost::multi_array as a private member of a class. How I can specifying the number of elements for every dimensions into the constructor? #include <iostream> #include "boost/multi_array.hpp" using namespace std; typedef boost::multi_array<int, 2> table; class X { public: X(); ~X(){}; // ... void do_something(); private: table tab; boost::array<table::index, 2> dims; }; X::X() { dims = {{3, 5}}; // fails table(dims); } int main() { X x; x.do_something(); system("PAUSE"); return 0; } Thanks to all.

How to inherit from boost::multi_array
by Thomas Mensch 02 Oct '04

02 Oct '04

Dear List, I am using boost 1.31.0 on Linux (with gcc 3.3.2) I would like to create a 2D array class, which inherits from boost::multi_array<double, 2> class. However I have problems with the copy constructor of my class Array. Below is the code, which I am trying to run. #include <boost/multi_array.hpp> class Array : public boost::multi_array<double,2> { public: Array (void) : boost::multi_array<double, 2> () {} Array (const int nrow, const int ncol) : boost::multi_array<double, 2> (boost::extents[nrow][ncol]) {} Array (const Array& other) : boost::multi_array<double, 2> (other) {} ~Array (void) {} Array& operator= (const Array& rhs) { if (&rhs != this) { boost::multi_array<double, 2>::operator= (rhs); } return *this; } }; /* class Array */ I guess that I forget to provide some information to my derived class, but I cannot find which one. Is there a way to simply inherits from boost::multi_array? Many thanks in advance, Thomas

[serialization1.32/vc7.1]: What's wrong with this class??
by Francis ANDRE 02 Oct '04

02 Oct '04

Hi I got a access violation on 0x00000000 with the class DDD but I cannot figure out what's wrong When the symbol NO_EXCEPTION is defined, the member acccode is set to an instance of ACCCODE and the serialization is working fine. But when this symbol is undefined, one gets the exception. I am suspecting the input serialization to bypass the loading of the member FIELD* field (which is following the "acccode" member) which leads to an exception when the next member DISP* disp is loaded but I have no way to check it out any idea??
