Hi,

I cloned a fresh xen-unstable tree and did:

# ./configure
# make dist
...
ld -r -d -nostdlib -L/home/hahn/Src/Xen/WorkingTree/xen-unstable.hg/stubdom/cross-root-x86_64/x86_64-xen-elf/lib  -m elf_x86_64 -\( /home/hahn/Src/Xen/WorkingTree/xen-unstable.hg/stubdom/vtpm/vtpm.a app.lds -\) -ltpm -ltpm_crypto -lgmp -lpolarssl --undefined main -o /home/hahn/Src/Xen/WorkingTree/xen-unstable.hg/stubdom/mini-os-x86_64-vtpm/mini-os_app.o
ld: warning: app.lds contains output sections; did you forget -T?
ld: cannot find -lgmp
make[2]: *** [/home/hahn/Src/Xen/WorkingTree/xen-unstable.hg/stubdom/mini-os-x86_64-vtpm/mini-os_app.o] Error 1
make[2]: Leaving directory `/home/hahn/Src/Xen/WorkingTree/xen-unstable.hg/extras/mini-os'
make[1]: *** [vtpm-stubdom] Error 2

What I found is that libgmp gets built and stored in
.../stubdom/cross-root-x86_64/x86_64-xen-elf/lib64
while on linking only the path
.../stubdom/cross-root-x86_64/x86_64-xen-elf/lib
gets used where all other libs are located.

The solution for me was:

--- a/stubdom/Makefile  Thu Feb 28 09:22:41 2013 +0100
+++ b/stubdom/Makefile  Thu Mar 07 10:00:10 2013 +0100

Id had this behavior on different machines but all with opensuse-12.2.
Do I something wrong in configure/compiling?
Thanks.

Dietmar.
