CGAL编译/链接器错误

Question

I'm trying to set up CGAL in Nvidia's Nsight Eclipse studio (Eclipse CDT). I don't plan on using it with CUDA, however I will need to use it for another part of a project that I am working on.

The error I am getting is this:

/home/me/work/x64_linux/cgal/include/CGAL/GMP/Gmpq_type.h:62: 
undefined reference to `__gmpq_init'

This is followed by several other identical errors regarding gmpq. I think it's a linking issue, but as far as I am aware, I'm not sure where I went wrong. My other dependencies link fine. I installed CGAL through apt-get, and followed the set-up instructions given in the manual. Perhaps I went wrong somewhere there, but long story short, I'm pretty lost in regards to getting this to work! Any help / tips are appreciated!

EDIT: Here is the solution, for anyone in the future that might stumble across this question.

For some reason, the IDE was referencing the library incorrectly, despite my inputs being correct. I simply opened a new project and migrated my files over. Adding libraries follows the standard procedure in Eclipse: Go to Project Properties -> Paths and Symbols. Add the path to the directory the library is located under to library paths, and add the library name to libraries.

Answer 1

1. Make sure that when you are compiling your code, you should be passing a -l option to the compiler to link to CGAL
2. If you are passing a -l option to the compiler, make sure that either the CGAL library is accessible from a folder in your path or that you are passing the full path to the CGAL library.

There isn't much more I can say without seeing your build setup.
