Hi I'm trying to use gnuplot-iostream, at the minute I'm just trying to get the code here working. When I try to combile I get errors in the linker saying:
In function `stream<int, boost::iostreams::file_descriptor_flags>':
/usr/include/boost/iostreams/stream.hpp:130: undefined reference to `boost::iostreams::file_descriptor_sink::file_descriptor_sink(int, boost::iostreams::file_descriptor_flags)'

collect2: ld returned 1 exit status
Note I have boost installed and have previously compiled programs that use iostream. Any help massively appreciated. Thanks
回答1:
Ruling out the obvious... are you compiling with g++ -lboost_iostreams? If you can share some information about how the compiler and linker are being invoked it will make it easier to answer your question.
回答2:
Run into exact problem when tried to use g++ with gnuplot-iostream library.
g++ prog.cpp -L/usr/lib -lboost_filesystem -lboost_system -lboost_iostreams
Resolved the issue for me - the code were compiled successfully with no errors.
