regex_match error
by Vikrant Rathore 05 Feb '04

05 Feb '04

Hi, I am using the regex library and using the following expression. But it seems it is wrong. Since there is no compilation or linker error but runtime error. the expression is boost::regex e("*\\.exe") and the call to regex_match is if (boost::regex_match((*dir_itr).native_file_string(),e)) But as soon as I use * it throws some runtime error. If I remove "\\." and "*". It works fine. Does anyone have such issue. Thanks with best regards, Vikrant

Subgraph and internal properties
by Hugues Joly 04 Feb '04

04 Feb '04

Hi, I'm posting again a question that got confused due to mistakes from my part... I'd like to clarify a point about internal properties accessed through a subgraph. According to the documentation of the method "get(PropertyTag, subgraph& g)": "vertex and edge properties are shared by all subgraphs, so changes to a property through a local vertex descriptor for one subgraph will change the property for the global vertex descriptor, and therefore for all other subgraphs." (c.f. … [View More]boost-1.30.2/libs/graph/doc/subgraph.html) Here, I'm sending you a small program inspired by the boost-1.30.2/libs/graph/example/subgraph.cpp example. >From its behavior, it seems that: 1) A property value is not shared between the global descriptor and its corresponding local descriptors. 2) we need to initialize property values for each of the subgraphs. For example, if I set a name "A" for the global vertex descriptor A, that property is not seen through the corresponding local vertex descriptors. Is this a case of misuse or is it a bug? __________________________________________________________ Lèche-vitrine ou lèche-écran ? magasinage.yahoo.ca /* Sample output: After initializing properties for G1: Global and local properties for vertex G0[C]...

Wayne, What configure script? Boost requires bjam.exe. If you follow the directions here: http://www.boost.org/more/getting_started.html you should have no problems. I have never had a problem with either MS Visual C++ 6.0 with regards to bjam, nor have I ever used a configure script with Boost.

For a number of reasons we don't have MS Visual Studio installed on the C: drive. We also have another SDK installed that uses part of Rogue Wave. Both libraries try to define min, max and a reverse iterator (there are items, those are the ones we've come across in an afternoon of experimentation). As I understand things, the ./configure script will look for conflicts with other libraries and try to work around them. The ./configure script is a bourne shell script, but there is no obvious … [View More]
