Re: HUGEPAGE support in binutils/linux

Hi,


So, I am trying to use libhugetlbfs as recommended, and I get an error
like this:
-----
/usr/share/libhugetlbfs/ld.hugetlbfs --verbose --as-needed  --hugetlbfs-align --hugetlbfs-script-path=/usr/share/libhugetlbfs/ldscripts <long list of object files> -lcrypt -ldl -lm -o foobar


ld-linux-x86-64.so.2 needed by /usr/lib64/libdl.so
found ld-linux-x86-64.so.2 at /lib64/ld-linux-x86-64.so.2
/usr/share/libhugetlbfs/ld.hugetlbfs: line 84: 18478 Floating point exception(core dumped) ${LD} "${args[@]}" ${HTLBOPTS}

laddu$ /usr/share/libhugetlbfs/ld.hugetlbfs --version
GNU ld version 2.19.51.0.14-37.fc12 20090722

If I try the exact same link operation with /usr/bin/ld without the
--hugetlbfs-aling --hugetlbfs-script-path=/usr/share/libhugetlbfs/ldscripts,
then it all works.

Help!


Thanks,
