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.

Invoking bjam without explicitly specifying any targets on the command line builds the project rooted in the current directory. Libraries can be either staticwhich means they are included in executable files that use them, or shared a.

Chapter Tutorial

This first builds the two projects on which the target hellobeatles depends, and then builds the target hellobeatles. By default, this option is set to minimalmeaning that only tutoriaal builds are created. 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 tutoriql work.

On Linux, system is the default setting. The above assumes that the Python installation is in c: As explained in Recipe 1.

Multithread-enabled compilation is another example of a typical target requirement. Projects inherit all attributes such as requirements from their parents.

In Windows for example, you can simply put these libraries inside the directory where the Python executable is.

For example, to build an executable from the source files listed in Examplecreate a file named Jamroot in the directory hellobeatles as shown in Example If you change to the directory containing Jamroot and titorial bjamthe three child projects will be built. The library probably has some headers that must be used when compiling app.


To portably represent aspects of target configuration such as debug and release variants, or single- and multi-threaded builds, Boost. When a building a target X depends on first building another target Y such as a library that must be linked with XY is called a dependency of X and X is termed a dependent of Y. The parent project of a subproject is defined by the nearest Jamfile or Jamroot file in an ancestor directory. But that’s a one-time effort and after that things are much easier than before.

Have a look at the following command:. As with any target, the alternative selected depends on the properties propagated from lib2 ‘s dependents. First, we need to specify our location in the boost project hierarchy. In all other cases, the most generic alternative 1 will be built. The kind of library produced from a lib target is determined by the value of the link feature.

Yes I ended up using a makefile, I just thought bjam had some kind of shortcuts for boost, but apparently it hasn’t. For example, in the following directory layout:. Tip Some other build system have special syntax for listing dependent libraries, for example LIBS variable. By default, debug variant is built. The target directory can also be specified with the –prefix option.

The solution is to use project ids—symbolic names not tied to directory layout.

Introduction – Installation

thtorial Then you don’t tutorjal to build any of boost libraries manually, bjam will take care of that itself as necessary. On Windows, the target directory is C: Instead of validating and tutoorial individual tuttorial separately, Boost. If a library is available as a prebuilt binary, however, you can declare a target for it as follows:.

Our objective will be to simply create the hello world module and run it in Python. However, as projects grow, that approach leads to a great deal of repeated boilerplate in Jamfiles.

Build, but surprisingly nothing on how to use it to build simple Boost applications. Here, library-name is the name that should be passed to the linker, which may differ from the actual file name, as discussed in Recipe 1. Sign up or log in Sign up using Google. There are many built-in features that can be combined to produce arbitrary build configurations.


For example, imagine that a library actually uses different tutirial files depending on the toolset used to build it. Static and shared libaries. For each library on which the executable depends—unless it is distributed as a prebuilt binary—create a Jamfile as described in Recipe 1.

One way to accomplish this in the present case is to change the names of the Jamfiles in the directories johnpaulgeorgeringoand hellobeatles from Jamroot to Jamfileand add to a Jamroot file in the parent directory with the following content:. Build testing facilities—the PATH variable will be automatically adjusted before running executable.


After a successful build, you can just link in these DLLs with the Python interpreter. Default value is sharedand to build static library, the value should be static. That will also ensure your app always links with the boost libraries compiled with the right options.

Be sure not to include a third number, e. When one library uses another, you put the second library in the source list of the first. When hello is built, the two requirements specified above will always be present. The answer is that some features are propagated —Boost.

Sometimes, particular relationships need to be maintained among a target’s build properties. Build, such as creating a user-config. They make it possible, for example, to tell whether a library has been built as a debug or release variant. Of course, any project can add include paths tutoroal those specified by its parents.

We’ve achieved our goal—if the library is moved to a different directory, only Jamroot must be modified.
