Hi All,
I've trying to build gcc-9.2.0 on a host with gcc-4.5.1, matching
versions of mpfr, gmp and mpc are symlinked into the top-level of the
tree.
This is my configure:
$ mkdir build
$ cd build
$ ../configure --prefix=/tmp/chroot-gcc/usr/ --enable-bootstrap
The following configure options don't sound sane at all :
--with-glibc-version=2.12 --with-newlib --without-headers
The glibc version should be automatically be found. The two next are for
embedded targets using newlib or nothing at all
as the target C library (no headers for it).
Better to check the current gcc-4.5.1, if configuring it included the
following :
--disable-nls
--disable-shared --disable-multilib --disable-decimal-float
--disable-threads --disable-libatomic --disable-libgomp
--disable-libquadmath
--disable-libssp --disable-libvtv --disable-libstdcxx
At least the '--disable-shared' isn't sane. The default for Linux etc
nowadays is to use shared ('.so*') files in linking and
when running apps.
