boost::filesystem::path question
Hi, I typically work on Windows and Unix. Our network has a bunch of shared drives that I can access from both Windows and Unix by using the form: //filesystem/some/path/ It looks like boost::filesystem is getting rid of the double slash at the beginning and replacing it with a single slash. This will work on Unix but WIndows needs the double slashes. Any way around this? thanks, matthew ************************************ This e-mail and any files transmitted with it are proprietary and intended solely for the use of the individual or entity to whom they are addressed.

The Windows regression tests contain lots of tests in the form //filesystem/some/path... for native paths so there shouldn't be any problem from Windows. On the Unix side, I'd need more information to figure out what is going on. For example, what Unix? What compiler? What software is the Unix system using to access paths on Windows machines? Do you do mounts, or is some other mechanism used? Do you have a sample of code you expect to work? --Beman
The following program sustains a segfault and, since the program is so simple, I have to believe the problem lies in my setup/system/build. I hope someone can provide me with some advice as to how I might proceed to further diagnose this problem. To this end, I've provided my system configuration, the compiler and linker options, the source code of the offending program, and a gdb stack trace at the point at which the segfault was sustained.

It's a good idea to put the name of the Boost library you're having trouble with in the subject line of your message, as I have done here. -- Dave Abrahams Boost Consulting http://www.boost-consulting.com

Well, that backtrace doesn't show any references to Boost.Test. I think you could get more information on STLPort forum. Gennadiy

The backtrace posted earlier in the thread does show references to Boost.Test, FWIW -- Dave Abrahams Boost Consulting http://www.boost-consulting.com

What it showed is global/static variables initialization, which includes unit_test_log, which refer to the std::ostream globals. And the crash happened somewhere inside iostream library. Gennadiy

Okay, sorry. I didn't look very closely. -- Dave Abrahams Boost Consulting http://www.boost-consulting.com
