Dbase on Power PC

[freddynerk]

I am writing a database program for a client on her PowerPC.
It uses TDBF for all databases. On my Intel machine all is fine.
It compiles to Powerpc without errors.
On her machine the program opens and works until
she selects Inv.dbf in a OpenDialog.
She then gets an Access Violation error.

Does her mac need anything extra to run.

This is the most basic of database design.

I have a powerpc only version on my web site.
Could someone with a powerpc test this for me please.

thanks in advance

Forgot to mention.
When the program starts press open and find the Data/Inv.dbf then open.
This will locate the folder for all databases.

For me it does not start up on my machine (a G5 running 10.5.7). If I run it from the command line, I get:

I remember reading about that error and afaik it's supposedly solvable by configuring a printer, but I have a printer configured. Maybe the problem is that the printer name contains a space? I can't rename it though, it's a network printer of the department.

I've found a post stating that tdbf does not work on big endian machines: http://forum.lazarus.freepascal.org/index.php?topic=1259.0

Edit: it turns out that post is outdated, see below.

[freddynerk]

Does this mean that I have to go back to square 1 with with my design.
I used Tdbf since I thought it was the most stable and idiot proof (silly me)

OH Well what can I use now.
My sister is not a happy person. (I'm not either)

How about Tsdf or Fixed format.
I assume one is a csv type file.

I think it's best to ask that in this forum: http://forum.lazarus.freepascal.org/index.php/board,16.0.html

I'll disable it for the 2.4.0 release for big endian targets, since it is misleading to ship units for a platform where they are known to be broken.

Actually, it seems that information is outdated. According to the release notes, it should work on big endian systems nowadays: http://svn.freepascal.org/svn/fpc/tags/release_2_2_4/packages/fcl-db/src/dbase/history.txt (see the fourth entry for V6.9.1).

Are you using FPC 2.2.4?

[freddynerk]

Yes I am using 2.2.4
and Lazarus 0.9.29 beta

Maybe there is hope.

[Jonas Maebe]

Lazarus 0.9.29 beta from which svn revision? (see Help->About Lazarus or Lazarus->About Lazarus depending on from when your version is).

Can you try with the latest 0.9.29 beta? You're not using the latest version, since osprinters.pas no longer has a line 295 anymore (which is where an exception is raised in my case)

[freddynerk]

Just had a look
The SVN is blank.
I have had problems with svn.
Should I get the latest Daily snapshot or grab something else.

Try the latest 0.9.27 snapshot.

The osprinters.pas reorganisation seems to have happened somewhere in 2008 however, so I don't understand how you can have Lazarus 0.9.29 beta with such an old LCL. Somehow it seems that you are using a new Lazarus together with a very old LCL.

I'm no expert on Lazarus/LCL issues though, so maybe one of the Lazarus experts can chime in.

tom, svn2 (vers. 1.6.x)

[freddynerk]

I am downloading the Daily snapshots.
Also I am using a set of components from Brazil called ajlaz-ctrls.
Maybe it is using an earlier printer file.
I will delete anything to do with printers from the package.
It has some nice components that I would like to keep.

Tom

[freddynerk]

I have just uploaded a new version at

http://www.ctd.com.au/mac.html

It has the latest daily snapshots.

I am of to sleep now.
I hope when I get up I will have happy news that someone has tested it and found it works.

Thanks again.
