Beginner with boost shared pointers

[panecasareccio]

Dear all,

I am trying to compile a c++ program that uses the library boost::shared pointers.

I have understood that if I want to compile and link it correctly, I must add the options -l(NAME OF THE LIBRARY) and -L(name of the directory) in g++.

I have used the command ldconfig -p to get the list of installed libraries in my system, but I do not find the one for shared pointers.

Below there is the subset of that list that contains the word "boost".

How do I locate the correct library for my purpose?

Thank you in advance,

Boost is (mostly) a header-only library, so you don't need to link anything for your particular purpose.

By the way, why use boost::shared_ptr when there is the perfectly good std::shared_ptr?

[panecasareccio]

Hi, thanks for your reply.

The reason to use boost instead of std is that the code I will write must be inserted into a larger software that is not compatible with c++11 :-(

If I understand you well, you are saying that I must only include the .h file and then compile the code as simple as:

g++ mycode.cpp -o mycode

Am I correct?

If so, then another beginner-question comes to me: how do I locate the .h files I need?


Thank you again,
Panecasareccio.

boost has a utility that will extract the header files you need along with the dependencies: http://www.boost.org/doc/libs/release/tools/bcp/doc/html/index.html
