Without knowing what the dependencies are, we can not answer this.
Can you provide information what units you are using or better:
provide a simple example?
I am on a pi every day, so I can test immediately.

I use onyl a button and form.  GUI is GTK. I cant send app. to you if
you want.

Thank u

Sounds like that you compiled the program for x86 architecture but try
to run it on arm! Although both run Linux, you will have to cross-
compile as the processor architecture is completely different!

I didnt change any thing about processor. I use default conf.

have to. A binary created with Ubuntu will not run under raspberry as
@dubst3pp4 already explained(different processor types). It's almost
like running a windows exe in linux or vice versa. You have two
solutions:
1. Compile the code under raspberry
2. Cross compile from ubuntu

What Getmem means you can not run an Ubuntu binary compiled for a
X86_64 or i386 intel architecture on an arm architecture. You need a
cross compiler for that or compile your code on the raspberry pi
itself.
You can install fpc using this link for RPi3:
https://www.freepascal.org/down/arm/linux-
netherlands.var#linuxbig302eabihf and this link for RPi1/2 :
ftp://freepascal.stack.nl/pub/mirrors/fpc/dist/3.0.4/arm-
linux/fpc-3.0.4.arm-linux-eabihf-raspberry.tar

That is recommended, because a standard ubuntu/armhf will installl fpc
2.6.2 which is very old. The above packages will install a current
release version (3.0.4)

Anyway: give us some code or the units you use and we will solve it.

You may need to install GTK2 libraries on Ubuntu on your pi , btw, did
you do that? It is no longer installed by default. Or are you simply
running Raspbian?
The first package link runs on Ubuntu/Raspberry pi since Ubuntu only
runs on RPi3 or newer Rpi2's (armv7a architecture)
