Help compiling with gcc/g++

问题

If I have a directory structure such as the tree below, what should my g++ command look like that would successfully compile the .cpp file that is in the taglib/bin dir, with all my .h files sitting in the taglib/include/taglib directory.

Anyones help would be greatly appreciated. Thank you!

-taglib

--bin
  .cpp file is here, incl headers are like this: #include <other.h>
  but wondering if it should be #include </taglib/include/taglib/other.h>,
  also, this should be where my binary will live when compiled.

--lib
  all my .so files live here

--include
---taglib
   all my .h files live here

The -I and -L options specify search directories for includes and libraries respectively. Therefore, you command should be something like:

g++ -o <xyz> taglib/bin/*.cpp -Iinclude/taglib -Llib

man gcc and even gcc --help gives great information on these particular command line options (and the GCC manual is fairly friendly too). You should really be trying them first before you ask here - it's more efficient (no waiting for answers!).
