Hi there,

(not sure this is the correct way or place to ask for this…)  
I just started playing within Julia, and I wanted to load a `.mat` file. So I tried to add the MAT package by typing `Pkg.add("MAT")`, but then during the brew install of the HDF5 dependency package, I got some errors. More specifically (I erased parts of the output):

```julia
==> Pouring gcc-8.1.0.high_sierra.bottle.1.tar.gz
Error: Failed changing install name in (...)
Error: Updated load commands do not fit in the header of (...)
Warning: Bottle installation failed: building from source.

```

It then goes on to build from source, but the `make` just hangs there for a looooong time… (Still running as I write this). Am I doing something wrong?

Please let me know,  
Cheers,  
Ben.

I had the exact same problem. Reading from the [HDF5 git repo](http://mirror.vsibiri.info/libraries.io/julia/HDF5.htm), HDF5 needs to be installed on your system before you can install it in Julia.

Try running

```julia
brew install hdf5

```

and then try building it with Pkg.build(“HDF5”).

Good luck m8

Oh thanks! Well eventually after an hour or so it finished building from source 🙂

Had the same problem, this helped.  
Still strange it doesn’t work automatically though…

It’s a problem with gcc bottle, it was reported to Homebrew, but it doesn’t seem to have been correctly fixed:

[https://github.com/Homebrew/homebrew-core/issues/27751](https://github.com/Homebrew/homebrew-core/issues/27751)

I would try to avoid updating packages in the meanwhile, unless you’re willing to recompile gcc.

I had the same issue. Running a `brew install hdf5` also resolved things for me.
