While trying to use Buckminster for both my Java and C++ projects, I realized that Java projects within Eclipse were pretty straightforward but C/C++ projects were much more difficult to manage.
Why is it so hard ?
Component materialization is much harder in non Java environments because :
- java projects dependencies are automatically described by the Eclipse plugin framework (no need to create CSpecs)
- Contrary to the C/C++ projects for which you have to write them.
- compiling, testing, your code requires to execute programs from outside ( shell scripts, compiler, unit tests and so forth ).
- some of the resources you need to materialize are libraries that are only available as zipped url resources.
- which implies you have to download and unzip them : Buckminster cannot do that for the moment despites its exactly what you expect it to do.
The toolchain I created to manage C/C++ projects dependencies is as follows :
- Create Spec components to describe dependencies
- Specify actions like build / clean / rebuild
- those actions have prerequisites pointing to other components (eg: the path to the libTiff include folder)
- Write ant scripts called from buckminster to
- retrieve libraries from urls or retrieve files from archives pointed by url
- execute commands with specific environment variables (eg. calling the compiler with paths to libraries)
- Create the script to compile the code ( Makefile or Boost Jamfile or SCons file )
This page is a proposal to extends Buckminster's actor in order to bring users from the non Java world a better experience in executing actions like
- downloading resources from the web
- executing shell scripts
