image reading: Magic++ exception

[Евгений Алексеевич Нурм инский]

Finally I managed to install 3.6.4 with Magic++. However when I tried to
read simple jpg-file just by copying the example from info,

I = imread ("myimage.jpg");

it complained:

error: imread: invalid image file: Magick++ exception: Magick: No decode
delegate for this image format (/dev/shm/my-pic-doc.jpg) reported by
magick/constitute.c:1528 (ReadImage)

The file itself is nothing special:

-r-------- 1 nurmi2 users 2063506 авг 18 10:57 my-pic-doc.jpg


Where to look for the cause ?
