Log in a file as the formatting has eaten the original paste.

wget-ing from the command line retrieves a file with the right checksum - I'll try again...

It's zero-length when retrieved via make

I don't think it is following the redirect.

Manually downloading to the expected location allows the build to proceed:

Grrr. Attached as a file again.

The make prior to the maual download failed fast - too fast to be actually trying to download the real file. Either it's not following the redirect or it doesn't like the surprising '*' in one of the returned urls along the redirection chain.

I think this is caused by the same thing as issue #2 (see my last comment in that issue), that is your cmake version does not have SSL-support. I'm looking for a way to require this during configuration, i.e. stating to the user that SSL is needed, or another way of downloading the source build-time. I think it's fair to say the user should not have to encounter the terse output you see here, which isn't really notifying you of the real issue.

This is indeed a duplicate of #2. I can make it go away by:

mkdir -p ../external/fltk
wget -O ../external/fltk/fltk-1.3.3-source.tar.gz "https://drive.google.com/uc?export=download&id=0B942d76zVnSeazZWcExRaXIyVDg"

after the call to cmake and before the call to make.

Great, I will resolve this issue once we figure out the permanent solution.

Any reason not to use the one hosted by fltk's site?

When we implemented this on-the-fly download and install, I kept getting different checksums and subsequent hash-mismatches. As soon as I got hold of one with the correct checksum I opted to have that in a more reliable location, but in principle there's no reason not to use the fltk-site version.

My cuda build box can't see the external network so I'm having to work round it anyway! Downloading separately and copying into place does the trick for both fftw and fltk.

Duplicate of #2.
