Hi All

I am having an issue with the Lnet visual component suite, I am trying
to use these on a Raspberry PI 3.

I am running Lazarus version 1.6 and FPC Version 3.0.0, because I need
to compile the Lazarus programs for the Raspberry PI Zero W as well
the Lazarus has been installed for the Armv6. I have installed the
LNet package with no issues and Lazarus subsequently builds with no
problems after the components have been installed.

The error I am getting is a run-time one, if I simply place a
TLUDPComponent on the form and then build the project and run I get
the following error.

Project project1 raised exception class 'External: SIGILL'. At address
75A82DE8. After I click the OK button I get an assembler window.

I have also tried the TLTCPComponent and this does exactly the same.

Any clues anyone

Regards Andrew

You might quickly try Control Terminal (http://www.ctrlterm.com/) to
make sure that networking is OK on your Raspberry Pi.

Hi Paul

I am pretty sure the networking is working correctly, there is another
package with the Lnet visual components and this is called lnetbase
these are added to your project but they are not installed as
components. I have made several applications with these and I can send
UDP packets from my PI 3 or my PI Zero with the programs compiled with
Lazarus. As these are not installed as components I have to have the
lnetbase files locally with each of the projects but they all work as
expected.
