I fixed the ecrm1000 bug that Javier Bevos hinted that it could be the
same thing, and you never got back to me, so I assumed it was solved.

You have to be more specific than "problem generating the format",
there can be many causes for a failure to find a font. I would
like to know:

* What operating system type are you on?
* Which format are you attempting to generate?
* Which version of luatex do you use?
* Where is the luatex executable on the filesystem?
* Where is the texmf tree (and that font) on the filesystem?

In the luatex distribution and the repository, there is a toplevel file
called INSTALL. This explains how to build luatex (albeit briefly).

Even shorter: you should run these two commands

	$ ./build.sh
	<wait for the build to finish>
	$ cp build/texk/web2c/luatex <texmf-bin-dir>

But that just for your information, the luatex source code is almost
certainly not the cause of luatex's inability to find and load
ec-lmr12.tfm.
