Henh, I'm sorry, I'm not sure what's going on there. It's possible that this is a bug in the build system or that I'm wrong and you do in fact need gcc 4.7 when building with intel. I thought I'd done a purely intel build before but turns out I used the intel fortran compiler and gcc

Yep, using that version of gcc definitely won't work. However, if you're using the intel compilers then you don't need gcc. If you haven't seen it, instructions for using the intel compilers are here . Cheers,

Using @eval in a macro is generally the wrong thing to do. A macro should simply transform an expression to another expression. If you give an example function body and what you want the macro to transform it to it would be easier to visualize what you want to do.

With respect to Eric's original issue, I suspect this is due to some global git configuration setting change you may have made. Julia's embedded git might be reading from your system-wide global git configuration settings by default. Run `git config -l` and see if anything jumps out at you.

Re: [julia-users] Re: Git-maggedon

There's an issue on that, Pkg.rm doesn't actually delete the files, it moves them to a .trash folder. There are reasons for this but it's counterintuitive and can lead to issues, so in future refactorings of Pkg it will be revisited. The .cache is not shared between Julia versions on Windows.

Normally installed packages are not supposed to (and never have been) on a branch – they are checked out to a specific commit for p package version. If you want to checkout a branch of a package, you can do Pkg.checkout("Foo") to checkout master or Pkg.checkout("Foo", "br") to checkout the "br"

I’ve never understood the various .cache folders that hang around, but if you want to be sure to start from a clean .julia package folder you might want to make sure all the .cache folders are also removed. In particular I guess the .julia/.cache folder. And then retry the whole Pkg.init()
