Re: repo update for free pascal and lazarus

Just get the uptodate versions by following the procedure on this chap's web page. The relevant bits start just before halfway down.

A brilliant guide and it ran straight through for me. The FPC/Lazarus procedure starts a little less than halfway down the page.

Thanks very much!

Re: Weather Station now running

Yes the rain gauge is a pair of tipping buckets on an arm with a magnet and reed relay, which is why mine used to read wrongly when it was up on a wobbly pole. The anemometer is the same, 1 magnet and a reed relay. Not looked inside the wind vane. but it's all only run from a single pair of wires.

Re: BMP085: two questions

Bought mine from a cheap Ebay seller. It arrived from China within a fortnight. It is within .1hPa of the one that's built in to my WH1081 weather station so I would think it's safe to buy cheaply.

Re: Lazarus and CodeTyphon.

I have to disagree strongly. Installed from a clean raspbian, with a good 16GB SD card, using the paths recommended by first Zog and then me in the main Lazarus thread, then it's very zippy and works well, even doing the development work over vnc. I've now got a modded version of the i2c library goi...

Re: Options for languages to use on the Pi

By day I'm a professional C#/F# developer, and an ex Pascal/C/C++ dev. When you say you've used Pascal, have you tried the full Lazarus graphics IDE on the Pi? It gives you an environment like Delphi and of course compiles down to ARM code executables very well. I run my Pi headless and use Lazarus...

Re: FPC/Lazarus - permissions to run app

You do need to run Lazarus as a root user to access the hardware. I do this at present using:

xhost +localhost
sudo /usr/share/lazarus/startlazarus

from a terminal window.
But there are probably prettier ways!

Re: free pascal / lazarus

After a lot of experiments, I came across the lnet package, which can be installed from the freepascal people and...

Re: free pascal / lazarus

I think it was plugwash who kindly packaged up the earlier version, looking back in this thread. So it needs someone with access to whatever autobuilder tools he used to put it into a form suitable for apt-get.

Re: free pascal / lazarus

The last time I looked at Real Delphi, it was vastly expensive and the firm that bought Inprise was still targetting it at corporate database stuff. I think, as a retired person, I shall support Lazarus! Now that I've finished hoovering, I've ordered the second 16GB card to install the new version on.

Thanks for your work Zog! I shall have to get myself another 16GB SD card so I can mirror my current one, which has the 0.9 version working OK, so I can safely try it.
Is there a reason why you went for 1.04 rather than the 1.06 that appears to be current?
