Context: A lot of packages that have binary dependencies on macOS use Homebrew to install them. A few months ago there was some changes that caused Homebrew to build GCC from sources instead of just downloading it. Building GCC from scratch take hours (and all your CPUs) and since a lot of packages …

is this at all related to: [image] Anyone know status of HDF5 build problems? New to Julia Just got this working about the same time you posted this. I think the thing that got me closest to the solution was doing: brew install hdf5 in the terminal. And then Pkg.buil…

Maybe I overestimate the issue, I don’t know if other packages beside hdf5 depends on gcc (I haven’t found a way to check this with homebrew). If HDF5.jl is the only packages suffering from this a solution might be to switch to BinaryProvider.jl for distributing the binaries and avoid problem altog…

Using BinaryBuilder/Provider would be a good solution but I’m not sure what to do with MPI. Do people generally need a HDF5 build that works with MPI or can the default be non-parallel? If people need an MPI linked HDF5 they might have HDF5 on their system already which BinaryProvider might be able …

If people need an MPI linked HDF5 they might have HDF5 on their system already which BinaryProvider might be able to detect Pretty sure that’s against the core philosophy of BinaryProvider + BinaryBuilder. But there should be no problem in adapting the build script to do this. Just have somethi…

I think having some standardized functionality for this would be useful. It doesn’t seem ideal that each package has custom code to handle these cases.

Well, if we have the write_deps in BinaryProvider, that’s probably all we can ask for. Base.Libdl.find_library is the closest a library can offer to help finding a system library, and check_version is highly library specific! :wink: It could be bundled in one function, but I’m not sure how that sh…

Not sure it is related but installing Cairo and Makie is quite troublesome now on macOS.

I hope mostly Cairo? That’s kind of unrelated, but hopefully soon fixed in some way by https://github.com/JuliaGraphics/Cairo.jl/pull/229 !

You are right. I cant get Cairo.jl to work on osx.

Cairo is being very awkward on both v0.6 and v0.7 at the moment. In https://github.com/JuliaGraphics/Cairo.jl/issues/230 you might find a temporary workround.
