LibPkg

LibPkg is a package management library for RISC OS. It includes classes to:
The first use of LibPkg will be as the back-end of RiscPkg, but it is not tied to any particular user interface and there could be other front-ends in the future. Parts of LibPkg are likely to be useful for writing package development tools and other types of package management utility.
LibPkg is currently at an early stage of development and it has not yet received extensive testing. Package managers by their nature have the potential to do serious harm to your filesystem. At this time it would be unwise to use LibPkg on a system you do not consider to be expendable.
(If LibPkg does go wrong then it is most likely to corrupt software that it itself has installed, closely followed by the contents of the !Boot directory. It is much less likely to touch user data, however now would be a good time to review your backup policy.)
Supported operating systems include:
Supported compilers include:
The Acorn C/C++ compiler (up to version 3.19 at least) is not supported because there are important parts of the C++ language that it does not implement.
The !LibPkg application directory can be located anywhere.
Ensure that it has been booted and/or run before attempting to compile or link against it.
(If two or more versions are present, running !LibPkg will change the active version whereas booting it will not.)
When compiling, append -Ilibpkg: to the GCC command line. This adds libpkg: to the list of paths that are searched for include files.
When linking, append -LLibPkg: -lpkg.a to the GCC command line. This adds libpkg:libpkg.a to the list of libraries searched by the linker.
Include directives should be of the form:
Be aware that all LibPkg classes are declared within the namespace pkg. You must either specify the namespace expicitly:
or place a using directive at the start of each source file:
Documentation available from the RiscPkg web site currently includes:
To build LibPkg from souce code the following tools must be present on the Run$Path:
Also required are the libraries:
Suitable versions of make, gcc and libfile may be found within supported distributions of GCC. fixdeps can be downloaded from www.riscpkg.org or using !RiscPkg or !PackMan.
No configuration is necessary. Change the current directory to !LibPkg then issue the command:
Please note that some difficulties have been encountered when using recursive makefiles with the experimental 32-bit version of make. They can be overcome by executing the makefiles individually from an obey file.
The RiscPkg home page may be found at:
and the original version of the library can be downloaded from the same location. This branch is now hosted on GitHub at https://github.com/alanbu/LibPkg
