Hi, Thanks for your detailed instruction and I installed boost lib successfully and my code using the lib can return correct results. Thanks a lot! Best Regards Pan On 02/16/2013 10:14 AM, Giovanni wrote:

Greetings Pan, I am using Ubuntu 12.04 with one of my machines.

I used the Ubuntu Software Center to install the Boost C++ Libraries, which makes things so much easier. You can enter "Boost" into the search box on the top-right corner, and find the Boost C++ Libraries to install. There are a number of them, including versions that conflict with each other. I chose the default version, and packages that don't conflict with that. I suggest that you install Boost C++ that way.

After you have installed Boost C++ with Ubuntu Software Center, you should/"should" (it depends on how you set things up and if you have root access) see the following.

The collection of header files for the Boost C++ Libraries in the location: /usr/lib. The collection of dynamic libraries (to be dynamically linked) for the Boost C++ Libraries in the location: /usr/include/boost.

To test if you have installed the Boost C++ Libraries correctly, run a very simple C++ program that includes one of the Boost C++ Libraries and calls a function from that library. For example, you can try my attached toy program.

To compile and run the program, try: g++ -o static2.out get_sys_info.cpp -lboost_filesystem -lboost_system ./static2.out

As for your specific problem, I am guessing that it is a linking error that I also had. You need to include the Boost C++ Libraries at the end of the compilation command (for GCC/g++). Hence, I placed the filename (C++ source file) before including the libraries.

I suggest that you post your compilation/linking commands, or makefile or script for build automation, so that people can help you. In addition, I would include the relevant source code (make it a simple C++ program, like my example) to test your Boost C++ installation. Furthermore, I would include the transcript from the Terminal. Just copy and paste what appears on the Terminal as you compile the program.

Good luck, and have a great weekend!

Regards

Hi all,

I'm a beginner to use boost library for my c++ coding project. After I include the in my cpp file and compile the code, the compiling error indicates that: fatal error: boost/algorithm/string.hpp: No such file or directory I search on internet and knows that I need to install some boost library. But which library should I install? (I tried to install the whole library with "sudo apt-get install libboost*", but it doesn't work.)

Can any one help me? I'm compiling and executing c++ on ubuntu Version12.04 environment

Thank you so much.

Best Regards Pan
