There is a weird error due to ImageMagick in travis CI ...

Any idea ?

[dcoeurjo]

Nope... works fine on my mac.
It seems to be Travis related

[JacquesOlivierLachaud]

Was there a change in version of ImageMagick in the travis CI ?
This error seems completely unrelated to this PR.

[dcoeurjo]

travis is using the last (brew) version of imagemagick. Weird because on my mac, I have the exact same version and no problem for me

[rolanddenis]

Also with the -DWARNING_AS_ERROR=ON option ? Because it seems to be a warning initially, but transformed into an error...

[dcoeurjo]

correct.. I see it as a warning also on my mac
we should deactivate the warning (using pragmas around the header files inclusion)

[dcoeurjo]

all good, thx, merging
