BJAM TUTORIAL PDF

Run bjam from the directory containing Jamroot as described in Recipe bjam dist. This copies the executable hellobeatles and the dynamic library georgeringo live online training, learning paths, books, interactive tutorials, and more. To automatically install the Boost libraries with , the command-line program bjam is used. The Boost libraries ship this program as source code and . finally the boost configuration file: // Jamfile import python ; project tutorial When I execute from my cmd prompt (after properly.

The following command builds the project’s release variant with inlining disabled and debug symbols enabled:.

Create a Jamroot file in the directory where you want the executable to be created. Instead of validating and compiling individual libraries separately, Boost. A Jamfile to bjak the executable hellobeatles. No matter what arguments are specified on the bjam command line, important will only be linked with the static version of helpers.

Rather than specifying all these files individually, you can use the install-dependencies features, which allows you to specify only the top-level executable target and the type of dependencies that should be installed.

If a library is available as a prebuilt binary, however, you can declare a target for it as follows:. If you change to the directory containing Jamroot and run bjamthe three child projects tutorisl be built.

Target alternatives can be used to associate multiple library files with a single conceptual target. Sign up or log in Sign up using Google.

It’s also possible to build or clean specific targets. With the command-line option –layoutbjam can be told to generate other file names. Multithread-enabled compilation is another example of a typical target requirement.

Installation

The following two commands, respectively, build or clean only the debug version of hello2. If the gcc toolset were used to link an executable target to pythonlib-lpython22 would appear in the command line other compilers may use different options.

The debug and release options cause both debug and release builds to be generated. First, we need to specify our location in the boost project hierarchy. As explained in Recipe 1.

This can take quite some time, which is why complete is not the default. Run bjam from the directory containing Jamroot as described in Recipe 1.

In a large project, a library can be used by many targets, and if they all use Jamfile location, a change in directory organization entails much work.

When core is built as a shared library, it is linked directly into utils. However, as projects grow, that approach leads to a great deal of repeated boilerplate in Jamfiles. In this section, we shall outline the steps necessary to achieve that. Build will deduce the its identity just from the name of one of its values. The target directory can also be specified with the –prefix option. Now, to build the release variant of helloinvoke.

For example, imagine that a library actually uses different source files depending on the toolset used to build it. For a complete reference to building Boost. Usage requirements are applied not to the target being declared but to its dependents.

Build to build an executable that depends on several static and dynamic libraries. If you start bjam without any command-line options, a default configuration will be used. This example defines two alternatives for lib2and for each one names a prebuilt file. Now let’s remove all the built products:. That will also ensure your app always links with the boost libraries compiled with the tutoriap options.

A better approach is to introduce a level of indirection. 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.

They make it possible, for example, to tell whether a library has been built as a debug or release variant. To portably represent aspects of target configuration such as debug and release variants, or single- and multi-threaded builds, Boost.

Tip Some other build system have special syntax for listing dependent libraries, for example LIBS variable. See Building Boost Libraries for further details.
