Recompile files

Recompile files

[Andrea Crotti]

I was wondering if I should recompile or not all my el files.  At the
moment I notice it takes quite long to boot at my emacs, and I guess
that would make it much faster.

But I also use the same configuration in different OS/versions.

So if I compile on one and then I copy the whole configuration on the
other I guess it might cause some troubles...

How do you handle this?  Should I keep everything compiled on each
machine and not transfer the *.elc files?

But then when I modify something I would again need to compile it
everywhere, and I would need some way to detect this automatically.

Someone has already solved this problem maybe?

Thanks

No, it won't.  The *.elc files are OS- and architecture-independent.
So you can use them on any platform without fear, provided that you
have roughly the same version of Emacs installed on all of them.

Ok good to know, but I would like to have this done automatically
- at boot recompile every new *.el file which doesn't have the compiled
  version

- check if the .el is newer than the compiled and compile it
  automatically if not

- check that the files are from more or less compiled with the same
  versions and print out a big warning otherwise...

By the way now emacs is eating too much memory, with nothing open
53Mb, just opening GNUS I reached 193Mb :O I don't think that's the normality

Yes, indeed! You should run GNU Emacs in a virtual machine with X11R1  
– then the number of shared libraries was negligible and their size  
very small. Dozens of them fit on a 20 MB disk. And there was still  
space for a dozen users and their data.

Ok good but I'm on a Mac, why should I use a virtual machine only to run
Emacs?

I also like the Cocoa version more than the terminal, and I think that
would not be possible right?

If I'm not wrong some time ago it was not eating so much memory, I guess
it's the configuration that needs a huge diet...

BTW, does this picture help a bit?

Or the OS... Use Activity Monitor and lsof a bit!

To most people solutions mean finding the answers. But to chemists  
solutions
are things that are still all mixed up.

Yes thanks, well running Emacs -q (always cocoa) and only loading gnus I
get more or less your values...
So I'll have to restructure my conf, which I'm already doing passing to
org-mode configuration...

But WTH is emacs-24? Are you ahead on time?

It's the new development version.

No. Right now I'am probably a few hours behind...
