[Boost-users] [Boost-user]multithreaded app hangs in boost libraries

Hello,

 

I have written a static library that uses boost program_options,
threads, date-time and serialization libraries.  There is also an
extensive use of shared_ptr.

I am working on a multithreaded application, so when I link my library
into the executable, I use multithreaded versions of the boost
libraries.  When I compile my library and application that links to it,
I use -pthread flag in attempt to make it multi-threaded.

 

Everything compiles and links without a problem, however when I try to
run the application, it hangs.  I have tried to bedug it and when I
suspend a hanging thread it gives me following stack trace:

 

      18 _dl_sysinfo_int80()  0x003317a2

If this post sounds familiar, that's because this is my second attempt
to get this problem resolved.

Previously I have been told that this sounds like I've built my
application with single-threading, and linked it to multi-threaded build
of a boost library, or vice versa.

Could you please let me know what's the right way to build my app with
multi-threading.

 

I am using Boost 1.34 libraries on Linux and compile with gcc 3.4.6

 

Thank you in advance for your help,

Inga
