Update README with install note #149

I suspect this advice is quite specific to OSX, and it might be good to clarify that before you get to the part about "removing Cairo from your system." On Linux, it would probably be bad advice to remove Cairo, since that seems likely to also force removal of the majority of graphical programs on the user's system. |
|
Oh I see. I wasn't aware of the Linux issue. I'll modify this. |
|
I trust this is good advice, but I'm going to let someone with a Mac make the merge decision---having literally zero experience with the beasts, I'm not the one to do it. |
|
What part of the tests fail? Ideally that would be in the binary verification hook to disallow loading that library. |
|
The build for this PR is failing because the AppVeyor build is failing on the latest 32-bit version, and the latest Mac version is segfaulting on Master. |
|
That's not what Keno meant. He was asking about what happened before you ran the steps you're describing here. What didn't work about Homebrew's version of Cairo? |
|
Oh I see. |
|
What version of Cairo.jl are you using? |
|
I did a |

Could we actually get steps to reproduce the bug so we can attempt to fix it? |
|
Ah, sorry, I was travelling a fair bit. I'll work on reproducing it now. |
|
I think this is a way to reproduce this on Mac. Have a fresh install of Julia v0.5 with Pkg.update()
Pkg.add("Cairo")
Pkg.test("Cairo")You're likely to see the same Now, after |

This is an auto-generated file; do not edit
# Pre-hooks
# Macro to load a library
macro checked_lib(libname, path)
((VERSION >= v"0.4.0-dev+3844" ? Base.Libdl.dlopen_e : Base.dlopen_e)(path) == C_NULL) && error("Unable to load \n\n$libname ($path)\n\nPlease re-run Pkg.build(package), and restart Julia.")
quote const $(esc(libname)) = $path end
end
# Load dependencies

And Pkg.build succeeds without an error? We should track that through to find out why that file is coming out empty. |
|
Yeah. Only once I unlink my system's cairo does Pkg.build do anything. |
|
please be more specific than "do anything." Exactly what do you see happen? |
|
Alrighty. Please forgive me for the long comment. In the beginning, I have cairo on my system, installed through Homebrew, and I have a blank Now after that, it begins to download And then it begins to build Cairo:
And that's it; it returns to |

Okay. So we need to figure out what happened with that first build, why |

This is not necessary anymore |
Does not seem obvious to me, so this note may be useful. Thanks.
