rpm building help SPEC.file

Question

I have a question to building an rpm package. I will bild an rpm package, which should copy some files on the computer. If no openssl is on the Pc I will also install it. At last I want to start some java programm to verify the succesfull installation.

Why is it not possible to just call a java class datei from the %post section. What did I do wrong? Is ist even possible to call one from inside rpm?

Also the $HOME Variable is not resolved in the %post section. How can I write to the coresponding file?

I am also open to idea of improvement. This is my first rpm package.

Thank you very much for your help

This ist the coresponding SPEC file.

Answer 1

1. No, you cannot call rpm from within an RPM.
2. If you require OpenSSL, you tag the RPM as requiring it - I know I sure don't want your version of it installed on my machine; I want the vendor's.
3. All the stuff in %install checking the versions of OpenSSL is being done on the build machine, not your target machine.
4. Don't put stuff in people's .bashrc or /etc/profile - that's what /etc/profile.d/ and others are for; you drop a file there, and then when uninstalled you remove it.
