Running a program compiled by Lazarus in another linux
lazarus / 66-Unix

I tried to make a simple application using lazarus in linux (Ubuntu
16.04).
After compile it, I try to run the compiled app in another linux
machine but the app cannot run.
I've tried using chmod + x appname command but nothing happen. the App
can only run on ubuntu 16.04.
what the problem?

Try this simple program and see if that will run on both machines. If
it does, you have a dependency issue and probably have to install some
libraries on the other machine or link statically.
Save and compile it from a console as: fpc -CX -XXs test.pas run as
./test
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i program
test; // program without external dependenciesbegin  writeln('test'); 
readln;end.
Also:
- has the second machine a compatible processor? i.e. you can't run
arm code on an intel
- has the second machine the same bitness? you can't run 64 bit code
on a 32 bit installation

To check your application setting for machine compatibility (as what
Thaddy said), do this:
Lazarus main menu > Project > Project Options > Config and Target

thank you thaddy.
i think, it may i compiled on 64 bit and run it on 32 bit.

Nice to meet you here.

ldd ./appname

and

file appname

can give you some info. Specially if you compare it with binaries that
come with the distribution

Marco, he tried to run a 64bit compiled executable on a 32 bit
platform...

Why in windows there is no difference between 32 and 64.
app that are compiled on a 32 bit can also run on 64 bits.

But not the other way around. 64 bit won't run on 32 bit.
In linux this is the same, but on most systems you have to install
multi-arch to run 32 bit code on 64 bit linux.
sudo apt-get install multiarch-support for debians like ubuntu.

Alternatvely you can install a chrooted minimal 32 bit subsystem, but
that's more complex.
