Re: [Starpu-devel] StarPU gcc plugin not building

[Miguel Palhas <mpalhas@gmail.com>]

Is it possible that this is due to the fact that i'm using a hybrid GPU laptop? I've had problems setting up CUDA, and currently it is installed but the NVidia GPU is not detected. I would expect it to just detect the CPU and ignore the GPU, since the driver itself does not detect it

Aparently, i didn't have Guile installed, but that didn't seem to make any difference.

I deleted /usr/local/lib/starpu and /usr/local/include/starpu, re-configured an recompiled starpu. The configure output included the following

checking for guile... /usr/bin/guile

...

StarPU Extensions:

...

   GCC plug-in: yes

   GCC plug-in test suite (requires GNU Guile): file

The output of gcc -v:

 % gcc -v

Using built-in specs.

gcc version 4.6.3 20120918 (prerelease) (Ubuntu/Linaro 4.6.3-10ubuntu1) 

I also just ran make check and everything passed (with 2 tests skipped, but i suppose that's not a problem).

Ouch.  It definitely works with 4.6.2 on x86_64-linux-gnu.

What’s the output of ‘gcc --version’, and what platform is it?

I suppose you didn’t run ‘make check’, did you?  (The GCC plug-in test
suite requires GNU Guile, as noted in the manual.)

Thanks,
Ludo’.
