failed to link against CUDA Driver API

[Aditya Bandla]

Hello,

I am new to UPCC & am trying to install it on a Cray EX HPC to ultimately install metahipmer.  I tried all the suggestions in the INSTALL.md file to enable GPU, but it always fails with the error "failed to link against CUDA Driver API"

Attached is the config.log file, any help would be much appreciated.

Thanks, Adi

Adi,

The HPE Cray EX instructions in INSTALL.md include the following arguments to configure, which I don't see in your config.log:

         --with-cc=cc --with-cxx=CC --with-mpi-cc=cc

Can you please try again with those included?

It is also possible that you need to `module load cudatoolkit` or something like that (can be system specific).

Sending us the output of `module list` might help.

If there are public webpages documenting use of the particular system you are using, please point us at them and we might be able to understand more about this particular system's configuration.

-Paul

Thanks, Paul! I did try using the flags, but it still failed with the same error.

The output of module list is as follows:  

1) craype-x86-rome
4) craype/2.7.15
7) craype-network-ofi
10) cray-pals/1.1.6
13) cray-pmi/6.1.1
2) perftools-base/22.04.0
5) cray-dsmml/0.2.2
8) cray-mpich/8.1.15
11) PrgEnv-gnu/8.3.3
14) cuda/11.6.2
3) gcc/11.2.0
6) libfabric/1.11.0.4.125
9) cray-libsci/21.08.1.2
12) openmpi/4.1.5-gcc11
15) craype-accel-nvidia80

I navigated to the specific part of the configure file, throwing an error. It was unable to locate the cuda library -lcuda. I found those files under the stubs directory within the cuda library directory. Adding this to LD_LIBRARY_PATH did the trick. I was able to compile & install upcxx, thanks once again for the support.

Regards, Adi
