To automatically install the Boost libraries with Boost. The kind of library produced from a lib target is determined by the value of the link feature.
Building a Complex application Using – C++ Cookbook [Book]
The Boost libraries ship this program as source code and not as an executable. Specifying properties in target references is especially useful if you use a tutoriaal defined in some other project one you can’t change but you still want static or dynamic linking bnam that library in all cases.
They make it possible, for example, to tell whether a library has been built as a debug or release variant. Build to install all dependencies that are executables or shared libraries.
Building Hello World
It’s not necessary in any way to use bjam in order to build code that works with boost. This can take quite some time, which is why complete is not the default.
We’ve achieved our goal—if the library is moved to a different tutoriwl, only Jamroot must be modified. Post as a guest Name. Build attempts to use dependencies with the same value of propagated features. Note that project ids are global—two Tutorisl are not allowed to assign the same project id to different directories. If you want file names on Linux to be the same as those generated on Windows by default, set –layout to versioned.
For example, imagine that a library actually uses different source files depending on the toolset used to build it. After you download the Boost libraries, change to biam Boost directory and enter the following commands on the command line:. The tutorial example can be found in the directory: Multithread-enabled compilation is another example of a typical target requirement.
The meaning of system wide depends on the operating system.
Usage requirements are applied not to the target being declared but to its dependents. A complex application may need to be installed together with a number of additional executables and dynamic libraries on which it depends. There are so many ways to set up the build incorrectly. Sometimes, particular relationships need to be maintained among a target’s build properties.
Target alternatives can be used to associate multiple library files with a single conceptual buam. Note for non-UNIX system. The Jamfile fragment below illustrates how these requirements might be specified.
For example, debug and release variants of a prebuilt library might be declared as follows:. This example defines two alternatives for lib2and for each one names a prebuilt file. After this brief bjam tutorial, we should have built two DLLs:.
Jam executables are available for most platforms. Then you don’t need to build any of boost libraries manually, bjam will take care of that itself as necessary. All three Jamfiles involved in building the executable hellobeatles are named Jamroot.
We can express this situation using target alternatives:. Projects inherit all attributes such as requirements from their parents.

To declare a target for a prebuilt library that has several variants, you can use the following notation:. The command-line options stage and install specify whether the Boost libraries are installed in a subdirectory called stage or are made available system wide. There is some initial configuration effort uttorial be done to prepare an environment for using Boost.
It belongs to the Boost libraries 1. If we want the same requirements for our other target, hello2we could simply duplicate them. Before anything else, you should have the bjjam executable in your boost directory or somewhere in your path such that bjam can be executed bjxm the command line. Static and shared libaries.
Instead of validating and compiling individual libraries separately, Boost. A specific compiler can be selected using the –toolset option.
Each project can specify a set of attributesincluding requirements:.
Build can create and use both kinds. There, you can find:.
