Re: [Boost-users] Simple Linking Error

Hi Daniel, I just did a little digging, regarding that particular error it has been suggested previously to add -pthread to your compile string. Could you give us more output like what other undefined references there are? Jay Daniel wrote:

including the -I/path/to/boost seemed to do the trick, however, once I started utilizing it (asio/date_time) I started getting things such as undefined reference to `pthread_detach'

Code directly taken from the tutorial here: http://asio.sourceforge.net/boost_asio_0_3_7/libs/asio/doc/tutorial/tuttimer...

Is there a list of the exact library names in boost/asio?

Hi Daniel,

Where were your boost header files and libraries compiled to? I had similar issues and John Maddock helped me solve a path issue. Try adding

-I/path/to/boost

to your compile string e.g

g++ -v -s -I/path/to/boost myfile.cpp -o myfile.exe

you might need to add the relevant -lboost_library_name_goes_here to the end of that compile string, where boost_library_name_goes_here is the name of the library you are using.

I thought this would be easier on linux than windows to be honest and here you are having some problems !

Hope this helps.
