confused at chapter 5.6


I am confused at what needs to be done in chapter 5.6. Linux-2.6.27.4 API Headers.

do I need to unzip the linux kernel at this point?
which direction is this command executed from?

where is 'headers_check' defined for 'make headers_check' step?

Also in the prior step for building gcc, were we just to unzip and rename files mpfr and gmp without building
these packages?

Kind Regards,
Rajinder Yadav

Well firstly you would have untar
the tar ball from kernel.org, then
move into the new kernel's source tree
to execute those commands.
or if your distribution already has a kernel
move to it's source tree to execute those commands.

mpfr and gmp need to be built and installed before compiling
gcc(or use the hosts systems gmp/mpfr i.g. apt-get install *
if your on debian/ubuntu).

Re: confused at chapter 5.6


Hi Justin,

thanks that cleared things up and I was able to proceed. 

Also, I was able to build and install GCC without any issues but I didn't build the supporting packages (mpfr
and gmp) and I don't have the devel package for them installed.

I guess it would be safe to rebuild GCC =) after building mpfr and gmp!

Kind Regards,
Rajinder Yadav

Hi Michael,

thanks for pointing out the important step, I would have glossed over it had it not been for you.

Kind Regards,

Re: confused at chapter 5.6


Hi Justin,

after Michael Tsang feedback on where to put mpfr and gmp, I went to the GCC build page and it states that if the
sources are put under the gcc source, they will get built when gcc is built:

Ref: http://gcc.gnu.org/install/prerequisites.html

Multiple Precision Library (GMP) version 4.2 (or later)
Necessary to build GCC. If you do not have it installed in your library search path, you will have to
configure with the --with-gmp configure option. See also --with-gmp-lib and --with-gmp-include.
Alternatively, if a GMP source distribution is found in a subdirectory of your GCC sources named gmp, it
will be built together with GCC.

Kind Regards,
Rajinder Yadav

SELinux


I noticed one of the switch passed when building glibc is --without-selinux

I assume the resulting LFS system, will it be missing Security Enhancement? If so what is required to build a
SE LFS system.

I assume SE is part of the Linux kernel and thus needs to be built as part of the Linux kernel?
