How does it not compile?  In addition to config.log, we need the error
message, otherwise we ca not say anything else than "works for us" :)

 

The problem with cholesky was resolved with libblas install.
sudo apt-get install libblas-dev liblapack-dev

What Linux distro do you use? Debian latest?

Config.log is a big file, so I posted mine on github: https://github.com/franciscoalecrim/starpunotes/blob/master/config.log

Wow, that's very odd.  You can run it by hand with
./datawizard/data_implicit_deps , does it fail everytime? Does it fail
with export STARPU_NCUDA=0 ? Does it fail without that variable but one
of ".cuda_funcs = {g_cuda}," or ".cuda_funcs = {h_cuda}," commented out?

Samuel

It does not fail when I run it by hand. FAIL only during the 'make check'.
export STARPU_NCUDA=0
$ ./tests/datawizard/data_implicit_deps
[starpu][starpu_initialize] Warning: StarPU was configured with --with-fxt, which slows down a bit

VAR 42 (should be 42)

I found two other problems with examples/binary/binary and examples/heat/heat.sh. But both works fine when I run it by hand. Minor problems! Not blocking my development.

examples/binary/binary - it's a permission denied solved with sudo.
[starpu][_starpu_opencl_compile_or_load_opencl_from_string] Error: Failed to open file </home/alecrim/.starpu/opencl///incrementer_kernels_opencl_kernel.gpu.vendor_id_4318_device_id_0>

and

examples/heat/heat.sh - Error below happens during 'make check' but works fine when I run by hand.
