I added ssockets now I can compile it.
I have this working with the ssockets unit added:
Try

I'm trying to figure out how TList works. I found the code example below by
doing a search, but I can't compile it, I get Error: Illegal qualifier on the
line
MyRec.Value := tmp;
It's indicating the error is on the V of Value
I tried commenting that line out, then I get the same error
Two observations:
1. In Pascal you should use "new" and "dispose" to allocate and
deallocate record types - not GetMem and FreeMem.
2. MyRec is a pointer type and you should code the line as
MyRec^.Value := tmp

Can you please give me an example of the correct way to use new and dispose?
I'll try the pointer
Thanks for the advice

Another way is to declare TMyRec as class instead of record.
In this case, you don't need the dereference operator ^ .
No need of new and dispose, just Create and Free, as for TMyRecList.
I don't know if there is a better performance when you use a record,
but as far as I know, record/object/n
I am using RPi3 and RPi4 platforms when working on RPi projects with
Lazarus 2.0.8 and Fpc 3.0.4.
Now I realized that the binaries I create will probably not work on
PiZero and RPi2 devices because these are Arm6 and the dev platform is
Arm7.
Is there some project setting I can activate in order t

I used Project/ProjectOptions/ConfigAndTarget and:

Hi,
I used TFPObjectList only once, for visual component TECAccordion
(https://wiki.lazarus.freepascal.org/Eye-Candy_Controls#TECAccordion). Each
item of list is derived from TWinControl so it is possible to use it even for
visual components (like TCollection).
However, in your case (record

Do you want an array of pointers (objects allocated
Hi,
some crippled formatting, so again:
However, in your case (records) I would rather use TFPGList from FGL unit:
1) add {$modeswitch ADVANCEDRECORDS}
2) add FGL to uses
3) define class operator =
test = record Port :String; Size :Byte; Status :Word; class
operator = (A,B: te

Thank you for the help, I'll give it a try!

What’s the difference between TList and TFPGList? Which one is better for this
example?

Is your FPC installation itself also built for ARMv6? (rtl and packages)

I would like to create a buffer into which a thread can push incoming

Data are coming from the serial port in a worker thread and should be
consumed by the main thread. The data is a byte stream.
Are there any good examples available?

The main difference is that TFPGList ist a generic, thus when you
specialize it with your record you'll have a typesafe object where yo
