How to find dependences of a created aplication
lazarus / 1-Linux

----------------------------------------------------------------------

Hi

I created some aplications (little programs for my little pupils   )
under delphi in the past, I ported it into lazarus to have the same
programs working under linux, all works great.

As I said I came from Delphi world in windows, where  after compile
the aplication you only have to copy the executable files (and
aditional files needed) to other computer and works without problems.

¿How can I use a lazarus program made under linux to another Linux
machine? In order to create rpm files to save dependences, ¿how can I
known which are the dependeces of my created programs?

Until now I found a "strange solution" that is to install lazarus in
the machines where I want to use this programs, but this is not a real
solution.

¿any sugestion?

Thanks

There is a tutorial about creating RPM packages for Lazarus software
here:

http://wiki.lazarus.freepascal.org/Deploying_Your_Application#Creating
_a_RPM_Package_on_Linux

Basically your program will depend on the toolkit library it was
compiled for. And also everything that library requires.

In the case of Gtk 1 you will depend on Gtk 1 and Gtk-pixbuf 1, and
also everything they depend, which is X11, glibc, etc, etc, etc...

To see exactly all the libraries any executable requires you can use
the command: ldd myexecutable

This command shows every library you depend on, directly or
indirectly.

When creating a RPM package you don´t have to worry about this because
RPM calls ldd on the executable automatically and adds the
dependencies for you.

I was trying to follow this wiki but I found a step that I don't know
how to follow.

"To build a binary package open a spec file with Emacs text editor. On
Emacs open the menu "RPM spec" --> "RPM Build" --> "Build Binary
Package". This will create a .rpm file under the directory RPM/RPMS"

I can't found this option in Emacs

[updated]

I have finally created my rpm packages.

I found a program named autospec what generates spec finles from a
tar.gz file very easy to create RPMS

It appears only when you are editing a file with .spec extension.

Even editing a file with .spec extension on emacs this option doesn't
apear anywhere


I'm using 21.3.1 under opensuse 10.1
