Unable to install

[balkierode]

First, I got an error that cmake was not installed. I installed cmake and then I get the following error

rust version 1.8.0. I don't think that matters though

Update Rust to 1.18.0. How old even is 1.8.0 at this point?

This is an issue of libgit2 (or, well, technically, libssh2-sys, but it's pulled in by libgit2) I've run across in the past (or one similar thereto, anyway). You're in terra incognita for me now, probably best course of action would be to yell at libssh2-sys maintainer.

[balkierode]

My bad (typo). it is 1.18

[nabijaczleweli]

Aye. Anyway, that "solution" still stands. It's shit, I know (I even wasted a good six hours on it or a similar one but I thought it was just my setup because it's weird), but yelling at the maintainers of libssh2-sys might get us somewhere.

[baileyn]

@balkierode you may need to try upgrading GCC. GCC <= 4.4 only accepted the flag -std=gnu89, but support was later added (after 4.4) to support -std=gnu90. I can't say that's the primary error, but I believe that's your main compiler errors when rust is building libssh2.

[perryprog]

Getting the same problem. Any solution? I kinda want to update my things...

[nabijaczleweli]

@perryprog Did someone finally open an issue over at the libssh2-sys repository? If not, that's the solution. If they did, then the solution is probably there. I have no idea why the libssh2-sys build error happens (and it seems to have different solutions on different systems) so I don't think I can provide anything beside that.

[perryprog]

Paging @balkierode: did you make an issue?

@nabijaczleweli Fair enough, I’ll do some research I suppose.

[mati865]

The only solution is updating system compiler (GCC in this case).

[perryprog]

@mati865 that’s lovely. I can’t update GCC right now, cause Homebrew doesn’t support High Sierra enough yet. I guess I’ll have to wait!

[balkierode]

@perryprog I didn't open an issue as I moved on to different system now.

[nabijaczleweli]

What's the status on this? @perryprog, does it work after updating GCC? @balkierode, does the issue persist on that "different system"?

[perryprog]

I'm not sure what I changed, (I assume I've updated GCC by now probably) but it installs fine now.

[nabijaczleweli]

Cool and good 👍
