FOLLOW-UP on the problem (for future reference)

After solving this problem as described earlier in this thread I went
on with my Delphi->FreePascal porting of an old project, which also
needed a serial port replacement component.
I chose LazSerial (available via Online Package Manager in Lazarus).
Now the same problem as outlined earlier in this thread popped up
again! In this case I found a few threads in the Lazarus forum where
the problem had a solution:
https://forum.lazarus.freepascal.org/index.php/topic,7143.msg33501.html
https://forum.lazarus.freepascal.org/index.php/topic,21998.msg129236.html
In the unit where LazSerial is referenced I added an extra uses item
like this:
{$IFDEF FPC}
interfaces, //Needed for LazSerial to work in a Console program
LazSerial, //The serial component
{$ELSE} //Delphi
When I now build the project the linker does not trigger any
complaints about missing Menu related identifiers and the build
succeeds!

That example used a form to display data rather than using the command line But I also had to remove that Indy unit before the errors went away. I have now tested that I can run the server on Win10 and connect to it. So I can now move forward.

The purpose is to check some Indy10 TCP communications items before
putting them into the main project.
So I have created a new project as a console application and
implemented my test Indy code.
When I use "Run/Quick compile" it reports no errors so then I tried to
use "Run/Compile" in order to get an executable but now it shows a
large number of errors of this kind:
IndyTest.lpr(76,1) Error: Undefined symbol: WSRegisterMenuItem
Looks like you have some GUI related code somewhere.
program IndyTest;
{$mode objfpc}{$H+}
uses
{$IFDEF UNIX}
cthreads,
{$ENDIF}
Classes, SysUtils, CustApp,
{ you can add units after this }
crt, //to check keypresses
remoteserver, //where the main action happens
indylaz;
I suggest to remove indylaz from the uses clause.
It pulls in some GUI related code, probably some design-time stuff.
Michael.
