Toolchain building

[Frank Schafer]

Hi,

I'm trying to build a custom Linux (something similar to LFS).

I've done so far:

Installed the kernel headers:
 mkdir /tools/include
 cp -HR include/asm /tools/include
 cp -R include/asm-generic /tools/include
 cp -R include/linux /tools/include

Installed glibc:
 ../glibc-x.x.x/configure --prefix=/tools \
                --disable-profile --enable-add-ons=nptl \
                --with-tls --with-__thread --without-gd \
                --enable-kernel=2.6.0 			--with-headers=/tools/include

 make
 make install
 mkdir -p /tools/lib/locale
 localedef -i de_DE -f ISO-8859-1 de_DE
 localedef -i de ...

Installed binutils:
 ../binutils-2.16/configure --prefix=/tools --disable-nls
 make configure-host
 make LDFLAGS="-Wl,--dynamic-linker /tools/lib/ld-linux.so.2" \
                 LIB_PATH=/tools/lib
 make install


Is it possible to bootstrap a dynamically linked gcc at this point.
Something like:
 ../gcc-3.4.4/configure ... --prefix=/tools ...
 make LDFLAGS="-Wl,--dynamic-linker /tools/lib/ld-linux.so.2" \
             CFLAGS="-nostdinc" \
             LIB_PATH=/tools/lib bootstrap
 make install

I can't figure out which BOOT_LDFLAGS / BOOT_CFLAGS or LDFLAGS / CFLAGS
I have to use for the step mentioned above.

Will I need all of the {,BOOT_}{LD,C}FLAGS or only some of them?

Did I get it right, that -nostdinc will lead to not using /usr/include?

Is there a common way not to run the fixincludes.sh or will I have to
edit the sources like the LFS nofixincludes-patch does?


Thanks for any idea
Frank
