How to build openmpi rpm from srpm cuda aware

Question

I would like to build the OpenMPI 1.10.2 rpm from the srpm. But I need to build it cuda aware.

According to the documentation (https://www.open-mpi.org/faq/?category=buildcuda) I need to add ./configure --with-cuda

Is there any way to do that while creating the rpm? I tried:

• rpmbuild -bb --with cuda openmpi-1.10.2.spec
• rpmbuild -ba openmpi-1.10.2.spec --define '--with-cuda'

But no success.

Answer 1

Use the second one, but edit the spec file. Find the call to ./configure or the %configure macro being called, and add your --with-cuda to that line.

rpmbuild -ba openmpi-1.10.2.spec
