Case in point : I distinctly reember reading a convoluted thread in one of the Debian lists about this /etc/alternative issue for gcc... Was I drunk ? Or what ?

I don't know what all this rant is about

The idiocy of having a system perfectly able to handle alternative packages ... except when it isn't, for reasons too obscure to be understood by a 31-year computer user (yes, I wrote my first Fortran program in 1974..) when he isnt a dedicated system maintainer. I *use* computers, dammit, I have not too much time to play system administrator....

but it's always best to keep the system compiler as chosen by the distributor.

That's exactly what I was trying to do. Debian has switched to GCC 4 for kernels. But (parts of) QEMU) need gcc 3.4. Hence the raindance..

If you want to use alternatives, use CC overrides or other configure option.

I missed the doc-"howto" for these options. Last time I tried, I ended up with "Incorrect module format" errores and/or bad compilations errors. I gave up and learned to change compilers...

If you can suggest a more steamlined way, I'd be happy to hear from it, and even more happy to read it on Fabrice's pages or somewhere in the documentation...

Use DKMS for kqemu modules?

No such thing on Debian. They have a (supposedly) nice system ("module-assistant") for compilong out-of-tree modules... which I never quite figured out. When I need an out-oft-tree kernel (which is rare nowadays), I still roll my own kernel, à la Neanderthal...
