Hello Simon,

thanks for the answer and suggestion.

My IDE is CodeBlocks, and I'm running it over Windows Vista 32.

My code is a simple example of the thread lib use:

Code:

#include <boost/thread/thread.hpp>
#include <iostream>
 
using namespace std; 

 
void hello_world()
{
   cout << "Hello world, I'm a thread!" << endl;

}
 
int main(int argc, char* argv[])

{
   // inicialize a new thread
   boost::thread my_thread( &hello_world );

   // wait for the thread end
   my_thread.join();
 
   return 0;

}

It's very simple, and when I try to compile it, I got these errors:

C:\boost_1_45_0\stage\lib\libboost_thread-mgw45-mt-1_45.a(thread.o):thread.cpp:(.text+0x7d)||undefined reference to `__Unwind_Resume'|

CodeBlocks uses MinGW as compiler, and due this is a C++ code, the g++ is been used (I guess).

note: I've built the boost using MinGW, not msvc.

Hello Bruno,

 

I have used boost libraries and they work for me on Windows.  To better understand your question,

You may want to tell which environment you r are using, i.e. VC9, Windows XP, …, and including a copy of the code that is failing may help also.

 

Cheers,

Simon

Subject: [Boost-users] Error '__Unwind_Resume' when trying to link codeblocks to boost::thread

 

Hi,

I'm a new user of Boost Libraries, and I'd use multithreading linking the
boost::thread class into my projetct.

I'm using Code::Blocks, and I've built the Boost in Windows, and then
I followed a wiki guide to link the libraries of the Boost.Thread with my Project in CodeBlocks.

However I found this reference errors:

C:\boost_1_45_0\stage\lib\libboost_thread-mgw45-mt-1_45.a(thread.o):thread.cpp:(.text+0x7d)||undefined reference to `__Unwind_Resume'|

||=== Build finished: 6 errors, 0 warnings ===|

What I have to do? I tried a lot of tutorials and guides in Google, but no one works...
