PostgresSQL and SocketClient components available

[Blacktony]

Hi folks,
I developed two packages. The first one, PSQL, implements two classes (TPSQLDatabase, TDatabase descendant and TPSQLDataset, TDBDataset descendant) for connecting Postgresql database servers. The second one, Sockets, implements one class (TSocketClient, TComponent descendant) for connecting to generic server sockets on  TCP/IP networks. A second class for Sockets package, the TSocketServer class, is coming. Packages can be downloaded on the web pages at the address: http://infoconsult.homelinux.net.

I hope that this stuff may be useful to Lazarus community. Any comment is welcome.

Bye for now

How to install it?

How to install it?

The tar.gz archive shuold be expanded from / under Linux
systems (cd /; tar xzf xxxx.tar.gz) . So, it create a folder psql
in standard lazarus components folder (/usr/share/lazarus/components).
Then, you have to install the usual way: from lazarus IDE open 'Components' in main menu, then 'Open package file' then select the .lpk file of your package (ie: for psql package, browse directories, go into /usr/share/lazarus/components/psql then select psql_laz.lpk). In the package manager window, press 'Install' button and answer 'Yes' when you are asked about Lazarus rebuilding. That's all.  Under Win systems, same way, just directories are different : useually components are in folder <some-drive>:\lazarus\components. So you have to make the right folder inside components folder then uncompress file into new directory using ie. winzip: int such a case, you have to unselect the 'Use folder names' (or something so).

Of course, it's not mandatory to use the lazarus standard component folder for hosting new components; that's just my way for have one place for all lazarus component.

Blacktony, do you want your component to be hosted on the Lazarus Code and Components Repositry?

If so, add a page for it, similar the the TAChart page and I will upload your component to the sourceforge file server.

Thank you Vincent.
Yes,  it's nice for me to add my components on CCR :lol:. I've added articles 'PSQL' and 'Sockets' on  http://lazarus-ccr.sourceforge.net .  
The PSQL page refers to version 0.4.2 of package that will be available on my pages from 2:30PM of today (local time, GMT +2).
I'll wait news from you.  Sorry for my english.

Hi, Antonio!
When try to compile the component TPSQL, occours a error:

/usr/share/lazarus/components/psql/psqldatabase.pas(1,1) Fatal: Can't find unit LResources

As, I don't can install this component. Any suggestion?

I am using debian etch, fp 2.0 and lazarus 0.9.8 beta.

Thanks!

Did you try cleaning your Lararus directory? ie: [menu]->File->Clean directory

Did you try cleaning your Lararus directory? ie: [menu]->File->Clean directory

No! Clear ALL directory and subdirectories from Lazarus (/usr/share/lazarus)?

Thank. Rafael.

Yes, All directory and subdirectories, assuming that's where you are compiling Lazarus to and running Lazarus from. You can set where Lazarus compiles to in [menu]->Environment->Environment options->Files->Lazarus directory.

I've got the same message in a Debian machine and with my XP one too.
I've tried with install or Compil, there's nothing to do, Can't find lResources unit.
in the same way, the folder where the components are installed in my debian machine is usr/lib/Lazarus/components and not in the /usr/share/lazarus/components, is this matter ? (i've not choosed, the installation does)

I have the same problem.
I have solve this by adding followed directories to compiler oprions of this package.
Remember Lazarus i have installed on path "/usr/lib/lazarus"

1) Other unit files:
/usr/lib/lazarus/lcl/;/usr/lib/lazarus/lcl/widgetset/
2) Other sources:
/usr/lib/lazarus/lcl/include/

WARNING !!
Unit directory a cleared originally this was bin "unit"
