Boost static linking
I am using the Boost library with g++ on Linux. When I built this library, I executed this command: ./bjam (without parameters). My lib directory looks like this: libboost_thread.a libboost_thread.so libboost_thread.so.1.41.0 ... Building the project using Thread library, I added boost_thread to the linker dependencies list. Now my program depends on the shared library libboost_thread.so.1.41.0. For my purposes, I need to make static linking, to exclude runtime dependency. How can I do this? -- View this message in context: http://old.nabble.com/Boost-static-linking-tp27714367p27714367.html Sent from the Boost - Users mailing list archive at Nabble.com.
Tried this, got error message: cannot find -llibboost_thread.a (added libboost_thread.a to the likker libraries list in the Eclipse CDT project). On Thu, Feb 25, 2010 at 5:14 PM, David Kaplan <davkaplan@gmail.com> wrote:

You need to add ":libboost_thread.a" - with the colon... Eclipse will call the linked with -l:libboost_thread.a
Thank you. This is my command line: g++ -o"MyProgram" ./main.o -l:libboost_thread.a The result is huge number of messages like: undefined reference to `pthread_key_create' The same result as I got with this: g++ -static -o"MyProgram" ./main.o -lboost_thread Some problems with static library libboost_thread.a?

Add -lpthread

namespace po=boost::program_options; po::options_description cmds("Options"); cmds.add_options() ("help,h", "output help message");
po::positional_options_description positional; positional.add("positional", 1);
po::variables_map vm; po::parsed_options parsed = po::command_line_parser(argc, argv).options(cmds).positional(positional).run();
Per documentation, this code only makes the first positional option be treated as option named 'positional'. You still need to define such an option inside an options_description object, since otherwise the library will have no idea what type it has and what to do with it. Does this help? - Volodya
