Yes, you are right. All this information is available through the 
fppkg-package. There's a Lazarus-package that also shows this 
information in the IDE, I'm not sure if it is still operational, though.


Trunk now supports 'fppkg info '

Okay, I'll check into more a bit later.

As a package manager, where is the description of packages? How is anyone
to know what webdesign is and what it does other than by just looking at
the package name and perhaps trying to google it?

The first google result for "fpc webdesign package" leads to a copy of a
mailing list question asking what the package does. After a bit more
googling it would seem that the OP is the author of the package.

To be of any value IMO, a package manager it ought to provide brief of
descriptions next to package names, otherwise people will have no idea what
they are looking at.

webdesign  add new form designer to Lazarus which can be used to build
websites

Also packages ought to be organized in such that the user knows what they
depend on or what is optional.

webdesign depends on lnet, gecko, embweb; optional jquery

I had to guess at the above and might be wrong. The only reason I picked
those packages is because they are only one which show up when libs isn't
configured they way fppkg expects.

I got it working, somewhat.

It would seem that you have to duplicate the entire FPC lib tree
underneath {UserDir}.fppkg/

The instructions at the page referenced in my last post are very unclear
about that.

I suppose under normal fpc install this is needed because the lib files are
typically only create as root under some folder other than your $HOME (done
during install). This copy (assuming everything in fpc/lib is needed)
results in an extra 900MB of files duplicated and eating up disk space (I
use small SSDs on my laptop),

However, since I always clone FPC and Lazarus from sources and build
somewhere under my $HOME folder (normally $HOME/Development/Base or
$HOME/Development/FreePascal), I was able to set LocalRepository
and GlobalPrefix in ~/.config/fppkg.cfg to my FPC folder
( $HOME/Development/Base/fpc) and then fppkg worked, sort of.

I found that almost all package were already "installed". I take installed
to mean the package source were are already included with FPC and compile
when I ran "make all" some time ago.

Of the 6 package not installed, I could only compile half. The rest
complained with results similar to the following:

That is not necessary. However, the request was to test with FPC  
3.0.0rc2 and from your previous mail it seemed that you were testing  
with 3.1.1 instead. I'm not familiar with all of the details of fppkg,  
but it's quite possible that
a) the official installer script sets up some global fppkg  
configuration (per version?)
b) the server where the package listings are stored also stores  
information per version

No, that should not be necessary. Fppkg uses two locations to install 
packages. One is {UserDir}.fppkg (the local version), but the other one 
should be the location where fpc is installed. That way there is no need 
to duplicate. Read the other mail for hints why it can not find your 
global configuration.


The instructions at the page referenced in my last post are very 
unclear about that.

This should have worked 'out-of-the-box', and it should work with fpc 
3.0.0-rc2, but it could be that you hane to tweak fpc 3.1.1.

Each compiler-version has it's own repository. I did test all packages 
in the 3.0.0 repository. I'll update the 3.1.1 packages later.

I had to start with *some* packages. I think that only lnet is of a real 
value, maybe I should remove the others. We should work on a decent list 
of packages. Maybe add 'libmicrohttpd', 'googleapi' and the new 
IPC-package...

You are using fpc 3.1.1. The repository for fpc 3.1.1 only contains the

This setting should point to the location where the packages are

/home/gigauser/Development/Base/fpc/bin/lib/fpc/3.1.1/fpmkinst/x86_64

And does this directory contain a lot of .fpm files?

It should...

[fpc-devel] FPC 3.0.0rc2 and fppkg

[Joost van der Sluis]

Hi all,

One of the new (or rather improved) features of fpc 3.0.0 is the Free 
Pascal packages repository, or shortly fppkg. Basically this is an 
online repository in which you can find several Free Pascal libraries 
that you can use in your projects.


It would be nice if some people can test if it works correctly. It 
should be configured correctly when you used one of the official 
3.0.0-rc2 releases.


First test would be to run 'fppkg list -l'. It should list the name of 
all available packages. All packages that come by default with fpc 
should be marked as installed. If this does not work, there is probably 
a flaw in the configuration. Or you are on Windows, in which case you 
should read the note below this mail. To troubleshoot the configuration, 
use 'fppkg listsettings'.


Second test is to install a package, for example fcl-base, by running 
'fppkg install fcl-base'. This should download the fcl-base package, 
compile it, install it, and thereafter recompile all packages that have 
a dependency on fcl-base. In case the code of these packages is not 
available it should also download those.


This test might look useless, as fcl-base is already installed, but try 
'fppkg list -l' after the installation. You will see that the fcl-base 
package is not installed into the default location (G, short for global) 
but in another location (L, short for local). The local-repository is 
user-specific and useful if you want to test a change in a package, or 
want to have the package compiled with different compiler settings.


So the next test is to install fcl-base with debug-information. You do 
this with 'fppkg install fcl-base -o -gl'. This will install fcl-base 
compiled with debug information and re-compile all depending packages. 
(With the same compiler-settings they were compiled with earlier - so 
normally without debug-information)


Now fcl-base is installed into the local repository with debug 
information, you can create an application using the contnrs unit, and 
see if you can step into it inside the debugger. If not, the Free Pascal 
compiler might not be configured correctly, so that is does not add the 
local repository to it's search path.


Instead of adding debug-information to a package, you could also try to 
add some new functionality to an unit in a package and install it 
without getting into troubles with packages that depend on the changed 
package, as they are automatically re-compiled.


Last, and real, test is to install a package that is not available in 
fpc by default. Like lnet.


Please test and send your findings here.

Regards,

Joost

Note for Windows users: It seems that there is a bug in the 
inno-installer of 3.0.0rc2, with as result that fppkg can not find the 
packages that are installed by the official installer. This should not 
be a big problem, as fppkg will download all the packages that it needs 
and install those. So in the case of fcl-base, it will also download and 
install all packages that fcl-base itself depends on.
There is one other issue, though, and that is that fppkg needs the 
fpmkunit-package to compile packages. There is a fallback-mode to work 
without fpmkunit, but this might not work in all cases due to another 
bug in 3.0.0rc2. You can work-around this bug by installing the fpmkunit 
package before you try to install any other package. ('fppkg install 
fpmkunit')
