I am in in ch 6 and done with tools of ch 5 and chroot stuff.
Now rebuilding Glibc-2.16.0 worked fine with the tools like tar and xz i installed in /tools.

when i check it :

make -k check2>&1 tee glibc-check-log
grep Error glibc-check-log

this is what I get:
make[2]:[/sources/glibc-build/rt/tst-aio.out] Error 1 (ignored)
make[2]:***[/sources/glibc-build/rt/tst-aio.out] Error 1
make[2]:***[/sources/glibc-build/rt/tst-cpuclock2.out] Error 1
make[1]:***[rt/tests] Error 2
make[2]: [/sources/glibc-build/conform/run-conformtest.out] Error 1 (ignored)
make:***[check] Error 2

Now both of them are given in the book, cpu clockcycles and conform test that we may encounter,is this the Good output?
I am confused whether am doing it right or not?

Hi

Did you try it with the timeoutfactor-16 maybe run it with that see if that improves outcome

The only one not mentioned explicitly in the book is this one: Have a look at the log to see if this is a time-out issue. If so: Continue with the build.

spiky0011's solution should also work (if this is time-out related). Not sure which one is faster.....
