Custom Makefile in sandbox

[Nicolas Le Moine]

Dear all,

I have a couple of Basilisk test cases with extra library dependencies (namely FFTW) and I am struggling to create a Makefile for running them on the server. On my local machine I have these two files in a same directory, just as in my sandbox:

http://basilisk.fr/sandbox/nlemoine/SWE/MacDonald/

I can successfully run "make subcritical.tst" locally, but the same setup does not work in the sandbox. Where do I have to put the "custom" Makefile so that it is taken into account ? Maybe the FFTW library is just not installed on the server, but it does not seem to be the problem in the first place as the compiling instruction displayed in the sandbox reads:

qcc -autolink -g -Wall -pipe -D_FORTIFY_SOURCE=2 -Wall -O2 -o subcritical/subcritical subcritical.c -lm

compared to the one I get locally:

qcc -autolink -Wall -O2 -g -Wall -pipe -D_FORTIFY_SOURCE=2 -DDUMBGL -o subcritical/subcritical subcritical.c -lfftw3 -lm

Thanks for any hint and sorry for the trouble, I am completely new to these Makefiles.

Cheers,

Nicolas

Hi Nicolas,

I have installed fftw3 on the server and fixed your Makefile, see:

http://basilisk.fr/sandbox/nlemoine/SWE/MacDonald/Makefile?changes=20211112170946

Another, simpler option is to add the line:

#pragma autolink -lfftw3

in subcritical.c

cheers,

Stephane

Ah, yes, also to make subcritical.c into a proper test case, you should
add a 'subcritical.ref' file and/or exit with an error status if some
threshold on the error is not verified. See:

http://basilisk.fr/src/test/README#error-checking

cheers,

Hi Stephane,

Thanks a lot for the fix, the #pragma option is much simpler indeed.

Cheers,

Nicolas
