this_thread::sleep + undefined reference?
Hello This will be an exceptionally stupid problem for whomever is kind enough to clarify a cause and solution. I will keep it brief in hopes that it is not an issue in need of complexity. The code: boost::this_thread::sleep(boost::posix_time::milliseconds(20)); The attempt: g++ -lcurl -lboost_thread -lpthread -pthread c.cpp -o app /tmp/cc2YRa76.o: In function `void boost::this_thread::sleep<boost::date_time::subsecond_duration<boost::posix_time::time_duration, 1000ll>

I will post more code if need be, but even general guidance will likely lead me to a solution. Thanks John

That is of course date_time. My fingers do that all the time. ;-) Jon
I regretfully failed to mention that i had tried that and base on what I had read, it was not even needed.

The code:
boost::this_thread::sleep(boost::posix_time::milliseconds(20));
The attempt:
g++ -lcurl -lboost_thread -lpthread -pthread c.cpp -o app
With gcc you usually need to put the library flags after everything else to ensure they are searched in the right order: g++ -pthread c.cpp -o app -lcurl -lboost_thread -lpthread Have you tried that?
