https://svn.boost.org/trac10/ticket/12301 <p> Brand new to boost. Downloaded and (apparently successfully) built version 1.61.0. Using recent (I think most recent) version on cygwin64 on Windows 10. First use was to try the tutorial programs for the boost filesystem package. Below is the linker output for tut1.cpp </p> <p> Any suggestions what I may have done wrong or where to look for solution? </p> <p> tut1.o:tut1.cpp:(.text+0x11f): undefined reference to `boost::system::generic_category()' tut1.o:tut1.cpp:(.text+0x11f): relocation truncated to fit: R_X86_64_PC32 against undefined symbol ` boost::system::generic_category()' tut1.o:tut1.cpp:(.text+0x12b): undefined reference to `boost::system::generic_category()' tut1.o:tut1.cpp:(.text+0x12b): relocation truncated to fit: R_X86_64_PC32 against undefined symbol ` </p> <p> boost::system::generic_category()' tut1.o:tut1.cpp:(.text+0x137): undefined reference to `boost::system::system_category()' tut1.o:tut1.cpp:(.text+0x137): relocation truncated to fit: R_X86_64_PC32 against undefined symbol ` boost::system::system_category()' collect2: error: ld returned 1 exit status make: <strong>* [Makefile:20: tut1] Error 1 </strong></p> en-us /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/12301 Trac 1.4.3 anonymous Mon, 29 Aug 2016 10:50:12 GMT
