Re: building GLIBC-2.4 header problem with ARM/NPTL/EABI

Forwarding to the list for their info...

There is an option "--enable-add-ons=ports,nptl" when building glibc
header. This option caused the error. I know the ports are used to
point the directory glibc-ports-2.4 unpacked. Well, can't NPTL be
supported by this way?

I have confirmed "--enable-add-ons=ports,nptl" should not be used to
build glibc header. I used "--enable-add-ons=ports," and got the
toolchain finally. (unfortunately, it has a lot of problems when
building modules and applications)

Hi
linuxthreads and nptl are two different implementations of the
threading mechanism. Up to glibc-2.3.6 you could use on or the other.
From glibc-2.4 linuxthreads does not exist, so NPTL is obligatory.
I currently build on two Debian x86 machines. On mine the build
works completely. It throws out "TLS is required" messages making the
gilbc headers, but carries on anyway.
glibc expects a native build so the default compiler is picks up should have the TLS support.
Currently these TLS checks are assembly files and while building glibc-headers we specify the host GCC
to be used. Hence these tests fail.

these tests could be changes so that they dont user CC but use AS in configure scripts (I have a patch for that which is attached)
and then we add --with-binutils=<path to cross binutils> option to glibc configure command to let it know where to pick the binutils
and since we already have built cross binutils before, so it will pick the right assembler at glibc-headers configure time


   On the other, the "TLS is required" stops the build. I don't know why.
   My only current lead is that the versions of "make" are slightly
different; mine is debian testing+stable updated to a few days ago
(make 3.81rc2); the other is the same + unstable, last upgraded in
January. (make 3.81beta4).
   I will be looking at this today; it may be that some of the options
are not being passed to the glibc-header-making step.
   I also have "Kernel version is too old" coming out as a #error in
the logs. Again, I need to look into this.
