Thank you @djsegal ! Success!
To clarify @djsegal’s suggestion a little, I:
- Went to the Homebrew website, downloaded and installed Homebrew normally (i.e. not through Julia)
- ran
brew install hdf5
in the terminal (not in julia) - THEN did
Pkg.build("HDF5")
in julia (0.6.3).
Success!
More generally, though, this still seems like a big general problem for new users – being able to read data and save things seems pretty central to Julia. Surely we can make this install work better?
(Sorry – I know it’s bad form to push for a fix to something open source if you aren’t in a position to do it oneself, but in this case I know NOTHING about gcc or homebrew, so am really not in a position to offer PRs. )
