I have four packeges to install gambas.
If i try gambas first, it tells me it needs the three others too (which are downloaded already)
If I try to install one of the libs, it tells me it needs the two other lib+gambas
I try them all, same result, they ALL need each other and there not way to disolve that problem, I can execut them all together.

help

thanks

I am assuming they are all rpm files. Put them all in a new directory, so they are the only files in there. Open a console. Change to that new directory (with the cd command). Run, as root using su, rpm -ivh *.rpm. And post back the results.

so cool, two minutes, jeremie, this is a LQ record or what!!!

error: Failed dependencies:

this though, above, is my fault, thanks a lot!

No probs - once you've fixed the dependencies all should be well.
