Errore durante l'utilizzo di Make per compilare GLIBC-2.11.1 per Linux da zero

Question

Sto costruendo LFS e sono nella parte in cui dobbiamo installare GLIBC-2.11.1

http://www.linuxfromscratch.org/lfs/view/6.6/chapter05/glibc.html

L'ho configurato correttamente ma non riesco a eseguire il comando Make. Ogni volta che eseguo il comando viene eseguito per un po ', poi si ferma.

Penso che le seguenti righe mostrino che qualcosa che ho fatto non è corretto:

Non capisco dove siano andate storte le cose. Cosa dovrei correggerli?

Answer 1

Devi installare gawk.

sudo apt-get install gawk

---

Il regex on line 19 era

/\/[^/]+$/

È un problema noto che mawk non capisce non scaped '/' nelle classi di caratteri almeno fino alla versione 1.3.3-15 (quello fornito su Ubuntu 11.04 (Natty)). mawk Penserò il / All'interno della staffa termina il regex e interpreta come \/[^, che è sicuramente un errore di sintassi a causa di senza pari ].

La correzione per glibc è banale: basta aggiungere a \ prima di /. Ma questo può anche essere un "controllo" dedicato per garantire gawk viene usato. Almeno questo non è ancora cambiato su GLIBC-2.14 ...
