11:08 < cheetos> hello i am trying to compile a simple mlpack program using g++-5. but i am getting a lot of compilation errors. These errors are shown in the hpp files of mlpack,boost and armadillo libraries. i am using "g++-5 -o" to compile. please guide me on how to successfully compile the program.

11:11 < zoq> cheetos: Hello, did you link against armadillo, boost and mlpack? Something like:

11:12 < zoq> g++ -std=c++11 -lmlpack -larmadillo -lboost_serialization -lboost_program_options test.cpp -o test

12:16 < cheetos> zoq: thank you for your input. i am not getting any of those errors now. but i am getting compilation errors of the form " undefined reference to `mlpack::Log::Debug' " when trying to compile the program given here: http://mlpack.org/docs/mlpack-2.0.3/doxygen.php?doc=iodoc.html

12:17 < cheetos> i have set LD_LIBRARY_PATH=/usr/local/lib/ but it didnt help

12:17 < cheetos> i am compiling with "g++-5 -std=c++11 -lmlpack -larmadillo -lboost_serialization -lboost_program_options test.cpp -o test"

12:29 < rcurtin> cheetos: if you installed mlpack in /usr/local/lib/, maybe it is not on the linker search path, so you should add -L/usr/local/lib/

12:35 < cheetos> rcurtin: i have installed mlpack in /usr/local/lib. Doesn't setting LD_LIBRARY_PATH=/usr/local/lib/ essentially do what you said?

12:36 < rcurtin> LD_LIBRARY_PATH sets the search path for the runtime dynamic linker, not for compilation

12:37 < rcurtin> so once you compile your program with -L/usr/local/lib/, then in order to run it you will need to set LD_LIBRARY_PATH (since when you run it the runtime dynamic linker must find all the dependencies that are needed to run the program)
