Let's see which wisdom file gets loaded:
$ strace fftw-wisdom 2>&1 |grep open
openat(AT_FDCWD, "/etc/ld.so.cache", O_RDONLY|O_CLOEXEC) = 3
openat(AT_FDCWD, "/lib/x86_64-linux-gnu/libfftw3_threads.so.3",
O_RDONLY|O_CLOEXEC) = 3
openat(AT_FDCWD, "/lib/x86_64-linux-gnu/libfftw3.so.3", O_RDONLY|O_CLOEXEC) = 3
openat(AT_FDCWD, "/lib/x86_64-linux-gnu/libc.so.6", O_RDONLY|O_CLOEXEC) = 3
openat(AT_FDCWD, "/lib/x86_64-linux-gnu/libpthread.so.0", O_RDONLY|O_CLOEXEC) =
3
openat(AT_FDCWD, "/lib/x86_64-linux-gnu/libm.so.6", O_RDONLY|O_CLOEXEC) = 3
openat(AT_FDCWD, "/etc/fftw/wisdom", O_RDONLY) = 3
Seems legit. What about the other wisdom binaries?
$ strace fftwf-wisdom 2>&1 |grep open
openat(AT_FDCWD, "/etc/ld.so.cache", O_RDONLY|O_CLOEXEC) = 3
openat(AT_FDCWD, "/lib/x86_64-linux-gnu/libfftw3f_threads.so.3",

Looks good.

openat(AT_FDCWD, "/etc/fftw/wisdoml", O_RDONLY) = 3
This is ok too.
$ strace fftwq-wisdom 2>&1 |grep open

3
openat(AT_FDCWD, "/lib/x86_64-linux-gnu/libquadmath.so.0", O_RDONLY|O_CLOEXEC)
= 3
openat(AT_FDCWD, "/lib/x86_64-linux-gnu/libm.so.6", O_RDONLY|O_CLOEXEC) = 3
openat(AT_FDCWD, "/etc/fftw/wisdom", O_RDONLY) = 3
LOLWUT?
When I explicitly read the wisdom file with `fftwq-wisdom -w /etc/fftw/wisdomq`
it works
Alas, concatenating all of the wisdom files together doesn't work.
