No. /tools/lib/libquadmath.so.* is useless now. After "6.10
Adjusting the Toolchain" the default dynamic linker should have
been changed to /lib64/ld-linux-x86-64.so.2 instead of
/tools/lib64/ld-linux-x86-64.so.2. Then it should search /usr/lib,
not /tools/lib.
MPFR configure script add "-lquadmath" if
echo "int main(){return 0;}" > conftest.c &&
cc conftest.c -lquadmath &&
./a.out
returns 0 (successful). But after 6.10 this should NOT succeed
because GCC spec has been changed to search /usr/lib instead
of /tools/lib and there is NO libquadmath.so in /usr/lib.
It's very likely you've made a mistake in 6.10. Please run:
echo "int main(){}" > dummy.c &&
cc dummy.c -Wl,--verbose | grep SEARCH | sed 's/; /\n/g'
It should contain "/usr/lib", and should NOT contain
"/tools/lib".
