I disable VT using “—enable-contrib-no-build=vt”, and it works. You should try
with this instead of “—disable-ft”.

Yes, thats what I thought and thats why I didn’t mention it as my main issue.
I’m rather stuck because cuda support and ob1 don’t
VT is getting out of sync with CUDA from time to time, this already
happened before.

I’m actually compiling with
./configure —with-cuda —disable-vt
because otherwise I get a compile time error:
make[5]: Entering directory
Hello,
I’m trying to evaluate the CUDA support in OpenMPI and I’m failing to get it to
work for both 1.7.3 and openmpi-1.9a1r29736. I tried on Ubuntu 13.04 and on
Fedora 14. I’m typically compiling with
./configure —with-cuda
but I tried combining it with various other options.
