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

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 #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'| C:\boost_1_45_0\stage\lib\libboost_thread-mgw45-mt-1_45.a(thread.o):thread.cpp:(.text+0x66f)||undefined reference to `__Unwind_Resume'| C:\boost_1_45_0\stage\lib\libboost_thread-mgw45-mt-1_45.a(thread.o):thread.cpp:(.text+0x771)||undefined reference to `__Unwind_Resume'| C:\boost_1_45_0\stage\lib\libboost_thread-mgw45-mt-1_45.a(thread.o):thread.cpp:(.text+0xdbe)||undefined reference to `__Unwind_Resume'| C:\boost_1_45_0\stage\lib\libboost_thread-mgw45-mt-1_45.a(thread.o):thread.cpp:(.text+0xe53)||undefined reference to `__Unwind_Resume'| C:\boost_1_45_0\stage\lib\libboost_thread-mgw45-mt-1_45.a(thread.o):thread.cpp:(.eh_frame+0x12)||undefined reference to `___gxx_personality_v0'| ||=== Build finished: 6 errors, 0 warnings ===| 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. 2011/1/13 Simon Mpasi

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

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'| C:\boost_1_45_0\stage\lib\libboost_thread-mgw45-mt-1_45.a(thread.o):thread.cpp:(.text+0x66f)||undefined reference to `__Unwind_Resume'| C:\boost_1_45_0\stage\lib\libboost_thread-mgw45-mt-1_45.a(thread.o):thread.cpp:(.text+0x771)||undefined reference to `__Unwind_Resume'| C:\boost_1_45_0\stage\lib\libboost_thread-mgw45-mt-1_45.a(thread.o):thread.cpp:(.text+0xdbe)||undefined reference to `__Unwind_Resume'| C:\boost_1_45_0\stage\lib\libboost_thread-mgw45-mt-1_45.a(thread.o):thread.cpp:(.text+0xe53)||undefined reference to `__Unwind_Resume'| C:\boost_1_45_0\stage\lib\libboost_thread-mgw45-mt-1_45.a(thread.o):thread.cpp:(.eh_frame+0x12)||undefined reference to `___gxx_personality_v0'| ||=== 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...
