Re: Busybox for powerpc doesnt compile

[Giriprasad Deviprasad <g_pr21@yahoo.in>]

Hi,

 Thanks for the details. Glibc configures, makes, and installs fine:
../glibc-2.9/configure --host=powerpc-linux --target=powerpc-linux- --prefix=/opt/mpc8250/tools/glibc2.9 --build=i686-pc-linux-gnu --with-headers=/opt/mpc8250/tools/ppc_6xx/usr/include/ --cache-file=config.cache

Now, I try to compile busybox.1.17.1 as :
 make ARCH=powerpc CROSS_COMPILE=powerpc-linux-

At the very end, errors as :
Trying libraries: crypt m
 Library crypt is not needed, excluding it
 Library m is not needed, excluding it
Final link with: <none>
powerpc-linux-strip: there are no sections to be copied!
make: *** [busybox] Error 1

.config:
CONFIG_EXTRA_CFLAGS="-I/opt/mpc8250/tools/ppc_6xx/usr/include/ -L/opt/mpc8250/tools/ppc_6xx/usr/lib/ -L/opt/mpc8250/tools/glibc2.9/opt/mpc8250/tools/glibc2.9/lib -nostdlib"


Can any please suggest why?

Thanks & Regards,
D.Giriprasad

This is not the right way to do this.  You need to use the proper flags
to configure.  config.cache is an implementation detail meant to speed
things up; it is acceptable for it to disappear at any time.

I strongly recommend you use a newer glibc.  There are definitely some
fixes to the PowerPC-specific parts of glibc, and that's just looking at
the Debian changelog, not upstream's.

You should look at config.log and see why it fails.  Search for the text
"size of long double" and you'll probably find the right place.
