Noob question - undefined reference to boost::system::get_system_category
I'm a relatively new to programming on Linux, previous experience was with VB.net in Windows. I'm trying to make the switch to C++, but I'm having a difficult time. I started to follow one of the basic tutorials for Boost ASIO, but I can't get it to compile with the ASIO.hpp file included. The environment is Kubuntu 9.04 and Kdevelop 3.5.3. Code: ---------------- #include <boost/asio.hpp> int main() { return 0; } ---------------- Compile Messages and Errors: ---------------- cd '/home/lance/TS1/debug' && WANT_AUTOCONF_2_5="1" WANT_AUTOMAKE_1_6="1" LC_MESSAGES="C" LC_CTYPE="C" make -k make all-recursive Making all in src compiling ts1.cpp (g++) mv -f .deps/ts1.Tpo .deps/ts1.Po linking ts1 (g++) linking ts1 (g++) ts1.o: In function `__static_initialization_and_destruction_0': /usr/include/boost/system/error_code.hpp:205: undefined reference to `boost::system::get_system_category()' /usr/include/boost/system/error_code.hpp:206: undefined reference to `boost::system::get_generic_category()' /usr/include/boost/system/error_code.hpp:211: undefined reference to `boost::system::get_generic_category()' /usr/include/boost/system/error_code.hpp:212: undefined reference to `boost::system::get_generic_category()' /usr/include/boost/system/error_code.hpp:213: undefined reference to `boost::system::get_system_category()' ts1.o: In function `boost::asio::error::get_system_category()': /usr/include/boost/asio/error.hpp:218: undefined reference to `boost::system::get_system_category()' ts1.o: In function `posix_tss_ptr': /usr/include/boost/asio/detail/posix_tss_ptr.hpp:47: undefined reference to `pthread_key_create' ts1.o: In function `~posix_tss_ptr': /usr/include/boost/asio/detail/posix_tss_ptr.hpp:61: undefined reference to `pthread_key_delete' collect2: ld returned 1 exit status make[2]: *** [ts1] Error 1 make[2]: Target `all' not remade because of errors. make[2]: Nothing to be done for `all-am'. make[1]: *** [all-recursive] Error 1 make: *** [all] Error 2 *** Exited with status: 2 *** ---------------- How do I resolve the boost::system errors?

You'll need to follow the instructions at http://tinyurl.com/ypdqsh and build the boost system library. In Christ, Steven Watanabe

How do I resolve the boost::system errors?
Thanks, Lance
Lance - You need to link against the boost system library also. Michael -- ---------------------------------- Michael Caisse Object Modeling Designs www.objectmodelingdesigns.com

How do I do that? I tried adding #include <boost/system.hpp> to the program, but there is no file by that name. -Lance -- View this message in context: http://www.nabble.com/Noob-question---undefined-reference-to-boost%3A%3Asyst... Sent from the Boost - Users mailing list archive at Nabble.com.

Lance - You need to *link* the system library. For example, it might be called libboost_system-gcc43-mt-1_37.so. See Steven's response which pointed you toward the Getting Started guide.

Alternatively it's possible to use the non-boost asio, which is header-only: http://blog.think-async.com/2008/05/boostasio-vs-asio.html
