Question about perl while bootstrapping gcc

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.

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.
