This is normal unix behavior (unless you have some kind of shell that I'm unfamiliar with.)

When you use & to create a subjob, it is still attached to your terminal session.

Take a look at the at(1) or batch(1) commands if you really want to execute a command and logout while it's still running.

Question about perl while bootstrapping gcc

[Dominique Dhumieres]

Hi!

I use to build gcc with a command line such as

make -j2 >& somelogfile &

I recently found that if I logout, the build fails with

perl: no user 501

Is this a bug or a feature? In the former case I'll open a PR.
In the later is it documented somewhere that you should not logout
while building gcc? If yes, is it possible to have a pointer?

TIA

Dominique

Try "nohup make ...".  See the man page or info manual for nohup.
