2) Lazarus only supports static packages. So installing a package
would always require to recompile Lazarus. I have no idea what the
progress on this topic is. Perhaps the wiki has something on it, or
someone from core can comment.
See
http://wiki.lazarus.freepascal.org/Lazarus/FPC_Libraries
When the ToDos are solved the IDE can be extended.
I added a few links to FPC wiki sites there.
Well, I have had a think about this library issue a bit further.
What I think we should devise or adapt is something a bit similar to the
python/perl library model.
This is what imho we should provide. The ideas are not so new I know:
- provide the ability to package up a directory containing all the
necessary files, source, docs, tests, examples data etc (ie akin to
the .deb or .rpm or .zip
- use/extend the existing fpc tools to load the package. They get
installed into a predefined directory like the /perl/site/lib directory
in perl.
- within fpc/lazarus, keep either an xml file or a database
holding names of all the installed packages.
- the tricky bit, is that within the package registration information
, there is a platform string and a version number somewhere.
- the package name, version and platform, go into the database.
- the compilable source files get compiled at package load time
and "integrated" into the system for use in the "uses" clause.
- it doesn't matter if the platform is different. The packages
can be compiled and installed on any platform. (Providing
they are marked as platform independant in their config
file)
- at run time, the libraries are kept within a specific directory
(/site/lib ?) as .dll or .so whatever files. All together with
all the other libraries. But away from the source files.
- fpc/lazarus uses these library files just as it would
internal functions...
Summary...
Maybe we already have some of the parts of this already.
It would be good to have something that works as simply as this.
Yes, I might be able to help with making it work if people want to go
this way.
