Using LazSerial in Console application

[soitjes]

Hi,

I would like to write a console application that needs to access the serial port.  I would like to use LazSerial which I also use in LCL applications.

So I add LazSerial to the Uses clause, and then I need to add a bunch of directories to the search path in the Project Options.  I get a lot of hints and at the end some strange errors :

xPLRFXConsole.lpr(77,1) Fatal: There were 49 errors compiling module, stopping

Does somebody know how to solve those undefined symbols ?  Is it actually possible to use an LCL component in a console application ?

Thanks,

The same errors are discussed here:

Thanks, that helped partially.  Interfaces was not found, with the message that I needed to add a dependency for LCL, but then I get

xPLRFXConsole.lpr(11,3) Fatal: Can not find Interfaces used by xPLRFXConsole, ppu=C:\lazarus\lcl\units\i386-win32\win32\interfaces.ppu, package LCL

So something is still missing I guess.

Make sure you are using the correct interfaces.pp; best to open Project Inspector -> Add -> Add Files and add ../lazarus/lcl/interfaces/nogui/interfaces.pp   Answer 'yes' when asked if you want to add this  directory to the path.
Under the New Requirement tab, you should add LazSerialPort to the Package Name field as well.

If you still have problems, try using trunk (Laz 1.1 / FPC 2.7.1)  This solved  my issues with adding LazSerialPort to component palette.

If the message is like this, then the compiler is actually managed to find the ppu, but maybe incompatible (right click and copy hidden messages in the messages window to see the full messages). Try recompiling the package (Run->Clean up build files might help).

DON'T DO THAT! Only COMPILED units should be known to the compiler. Therefore, adding LCL as dependency should be the fix.

hmmm.... seems I tried that and it didn't work, maybe I am wrong there.  I will have to go back in and try it on my other system to verify what I was doing.
I had worked on this for a while, first trying to install the LazSerial component on this box with no success, and then installing it on the other system and troubleshooting the problems with the console app, so I was probably just confused

Thanks for your tips.

I did "Run->Clean up build files" than then it compiled.  Now I can compile it as well with a simple compile.

Thanks again,

Soitjes.
