Hi Kenneth,
I needed this because while compiling an internal application I
noticed that it requires "libfftw3f_threads.so". As my compute nodes
have fftw-devel rpm installed the build system was using this library
from the system. After recompiling my FFTW module with --enable-shared
the application uses the libfftw3f_threads.so lib provided by my FFTW
module instead of the system one.
These are the contents of my $EBROOTFFTW/lib/ folder when compiling
with --enable-shared. It includes both the static and dynamic libraries:

IMHO, it makes sense that the FFTW installation in easybuild provides
both the dynamic and static libraries so applications depending on the
fftw dynamic libs can use the easbuild FFTW module. Does this have any
drawback I am missing?
Note that I'm aware of, it's probably that nobody has needed the dynamic
libraries specifically...
So, a PR to add --enable-shared would be nice. ;-)
Ideally, also with updating the sanity_check_paths...

Pablo.

Hi,
I have noticed that FFTW-3.3.3-gompi-1.4.10.eb is not building
the dynamic FFTW libraries. For this I think the fix would be to
change configopts from this:
common_configopts = "--enable-threads --enable-openmp --with-pic"
to
common_configopts = "--enable-threads --enable-openmp --with-pic
*_--enable-shared_*"
Is there any reason why the provided FFTW easyconfig is not
building the dynamic libraries. Would it be safe to apply this
change so the dynamic libs are built? or is there any issue which
could be triggered by doing this change which I am missing?
It's probably just because nobody has had a strict need for the
dynamic libraries yet? What's your use case for needing them?
The only thing I can think of is that by using --enable-shared the
static libraries may not be built anymore, but you'll have to
check that (and the sanity check should fail anyway in that case).
regards,
Kenneth
