Boost undefined reference during compiling

I am getting a compile error trying to compile a simple tester program from the documentation.

C:\DOCUME~1\A\LOCALS~1\Temp\ccRsXzHu.o:tester.cpp:(.text+0xa6): undefined reference to     `_imp___ZN5boost6thread4joinEv'

collect2: ld returned 1 exit status

I am using mingw 4.5 and g++ 4.5.2 on windows. Boost version v1.4.8.

I hope someone can help me solve this problem.

Thanks.

Make sure you've got all your libraries linked properly.

Try putting this line first if your thread library is statically defined 

#define BOOST_THREAD_USE_LIB

Also, check out this thread.

It looks like you aren't linking to the boost libraries.

Boost doesn't come with windows since it isn't a standard library. You've got to download the headers and libraries, then include the headers in your project and link to the libraries at compile time. Since you're using g++, this means adding a -l line to your compile command. The -l line must be used with each specific library you want to use also, you can't just specify the boost directory.

This page will help you get started on Windows and this page will help you get started on *nix platforms.

Once you've compiled boost, then in your example, you should compile your program with

g++ -o tester.exe -Lpath/to/boost/libraries/ -lboost_thread tester.c
