This article mainly introduces how to install boost 1.69 library under Linux, the content is detailed and easy to understand, the operation is simple and fast, and has certain reference value. I believe everyone will have some gains after reading this article on how to install boost 1.69 library under Linux. Let's take a look at it.

Boost library is some extended functions for C++ language standard library, including algorithm library, template metaprogramming, data structure library, image processing library, iterator library, input and output library, which can greatly improve the efficiency of software development.

#UNICODE character sets that support regular expressions

linuxidc@linuxidc:~/www.linuxidc.com/Linux Public-$ sudo apt-get install Python-dev

#Python is needed

linuxidc@linuxidc:~/www.linuxidc.com/Linux Commune-$ sudo apt-get install libbz2-dev2, Download the installation package sourceforge.net/projects/boost/files/boost/1.69.0/

Here I downloaded boost 1.69, 0 unzipped to a directory

3. CD to this directory

There is a bootstrap.sh script file inside, run this script to run the script:

linuxidc@linuxidc:~/www.linuxidc.com/Linux Commune-/boost_1_69_0$ ./ bootstrap.shBuilding Boost.Build engine with toolset gcc... tools/build/src/engine/bin.linuxx86_64/b2Detecting Python version... 2.7Detecting Python root... /usrUnicode/ICU support for Boost.Regex?... /usrGenerating Boost.Build configuration in project-config.jam... Bootstrapping is done. To build, run: ./ b2 To adjust configuration, edit 'project-config.jam'.Further information: - Command line help: ./ b2 --help - Getting started guide:

According to the above diagram prompt, carry out compilation operation.

4. Start compiling boost

Compiling takes a little time, go jump rope, fight boxing, enter the command:

linuxidc@linuxidc:~/www.linuxidc.com/Linux Commune-/boost_1_69_0$ ./ b2Performing configuration checks - default address-model : 64-bit - default architecture : x86Building the Boost C++ Libraries. - C++11 mutex : yes - lockfree boost::atomic_flag : yes - Boost.Config Feature Check: cxx11_auto_declarations : yes - Boost.Config Feature Check: cxx11_constexpr : yes - Boost.Config Feature Check: cxx11_defaulted_functions : yes - Boost.Config Feature Check: cxx11_final : yes - Boost.Config Feature Check: cxx11_hdr_mutex : yes - Boost.Config Feature Check: cxx11_hdr_tuple : yes - Boost.Config Feature Check: cxx11_lambdas : yes

The screenshot after successful compilation is as follows:

5. Start installation

Install the boost library related files to/usr/local. Enter command:

sudo ./ b2 --prefix=/usr/local/boost install

Screenshot after installation:

Add the boost library to the environment variable. Enter command:

gedit /etc/environment

Add the following path to the file:

CPLUS_INCLUDE_PATH=/usr/local/boost/includeLIBRARY_PATH=/usr/local/boost/lib

After the addition is complete, save the operation.

6. Test cases

(1) Writing the code. Enter command:

linuxidc@linuxidc:~/www.linuxidc.com/Linux public-/boost_1_69_0$ gedit linuxidc.com.Boost.cpp

Open the editor, enter the following code and save:

#include #include using namespace std;int main(){ boost::gregorian::date d(boost::gregorian::day_clock::local_day()); cout ". " ". " return 0;}

(2) Code compilation. Enter command:

linuxidc@linuxidc:~/www.linuxidc.com/Linux public-/boost_1_69_0$ g++ -I /usr/local/boost/include -L /usr/local/boost/lib linuxidc.com-o linuxidc.com

(3) Implementation procedures. Enter command:

linuxidc@linuxidc:~/www.linuxidc.com/Linux Commune-/boost_1_69_0$ ./ linuxidc.com2019.Mar.20
