What you're seeing is exactly what is supposed to happen. If you
want GCC
to be built by the new compiler then don't use --disable-bootstrap.
Yes, but the full-build takes a whoppy ~ 111 minutes here, whereas
the non-bootstrap build takes only 12 minutes to make. A big
difference.
How can I use the quick build variant with the new compiler?
If I don't use --disable-bootstrap, as you suggest, then it takes,
as said, ~ 111 minutes to make... :-(
Can't you add CC=my_new_gcc and/or CPP=my_new_g++ to the make command
for the second step?
Yeah, that seems to be the way to go.
Currently trying a variant of that method, indeed:
configure --help does not mention these variables:
CC_FOR_BUILD
GCC_FOR_BUILD
CXX_FOR_BUILD
I'm currently trying via them.
If it fails, then I'll add also:
CC
CXX
and maybe also CPP and GCC (after consulting the Makefile)
Ok, finally solved! :-)
With the following ./configure params (each having the new name of the
respective compiler) it now works as desired:
../gcc_trunk/configure -v \
...
CC="$my_CC" \
GCC="$my_GCC" \
CXX="$my_CXX" \
\
CC_FOR_BUILD="$my_CC_FOR_BUILD" \
GCC_FOR_BUILD="$my_GCC_FOR_BUILD" \
CXX_FOR_BUILD="$my_CXX_FOR_BUILD" \
\
CC_FOR_TARGET="$my_CC_FOR_TARGET" \
GCC_FOR_TARGET="$my_GCC_FOR_TARGET" \
CXX_FOR_TARGET="$my_CXX_FOR_TARGET" \
\
...
