Hmmm, well you can also try --without-zstd. There was a commit last
year to ensure this flags is respected.
commit 0fb0240a051df91d3c24385d1d3c17548b266544
Author: Martin Liska <mliska@xxxxxxx>

Fix handling of --with{,out}-zstd option.
PR lto/94259
* configure.ac: Respect --without-zstd and report
error when we can't find header file with --with-zstd.
* configure: Regenerate.

|--with-native-system-header-dir=dirname|
Specifies thatdirnameis the directory that contains native system
header files, rather than/usr/include. This option is most useful if
you are creating a compiler that should be isolated from the system
as much as possible. It is most commonly used with
the--with-sysrootoption and will cause GCC to searchdirnameinside
the system root specified by that option.

I'd like to build gcc for a chroot on my current system. Linux From
Scratch uses a method of faking a cross compiler by modifying the vendor
field of the target string. For example, changing x86_64-pc-linux-gnu to
x86_64-lfs-linux-gnu. I'd like to know if there's a way of avoiding
this. While GCC builds fine for my host natively and it builds fine with
the LFS method, I have so far been unable to build a host isolated copy
any other way.
I understand the recommended order is to build binutils and gcc first,
then build glibc with them and finally rebuild gcc against that glibc.
# I built binutils like this
../configure \
--prefix=$DISTRO/root/bootstrap \
--with-sysroot=$DISTRO \
--disable-nls \
--disable-werror
&& make -j6 && make -j1 install
# Then I tried to build gcc like this
../configure \
--prefix=$DISTRO/tools \
--with-glibc-version=2.11 \
--with-sysroot=$DISTRO \
--with-newlib \
--without-headers \
--enable-initfini-array \
--disable-nls \
--disable-shared \
--disable-multilib \
--disable-decimal-float \
--disable-threads \
--disable-libatomic \
--disable-libgomp \
--disable-libquadmath \
--disable-libssp \
--disable-libvtv \
--disable-libstdcxx \
--enable-languages=c,c++
&& make -j6 && make -j1 install
But this fails with a bunch of undefined references to the ZSTD
namespace such as ZSTD_getErrorName from gcc/lto-compress.c. I assume
this means that ./configure has detected that my host system has libzstd
but it's trying to look for them in the sysroot, where it obviously
can't find them. This happens even if I use --disable-lto.
Build System (Arch Linux): linux 5.13.13, glibc 2.33, binutils 2.36.1,
gcc 11.1.0
Target System: linux 5.13.12, glibc 2.34, binutils 2.37, gcc 11.2.0
So I'd like to know if I should continue like this, and if so how, or if
there is a better (maybe canonical) way of building a host-isolated
compiler?
