Yep, I figured it out, installed Berkeley DB via brew, compiled it, launched. All good. Now I need a blockchain

Nothing on your part. It's a bad build.

Hidden behind the exuberant splash screen lurks a hidden dialog box reporting a BDB error.

(Turn off the splash screen with splash=0 either in config or command-line arg.)

I'll fire up the Sierra VM, see if I can guess what I did wrong.

Edit: But not before setting up that cron job

Aha, a hint. While the daemon was halted, I checked the server's db.log:


That's the cause of the problem, I reckon. Next step is understand precisely what the log message means.

Thanks to @gihiggins I now have a working OSX Slimcoin client (didn't work out smoothly, I had to reinstall Berkeley DB, but in the end it worked). Now the network seems very slow, I estimate that a full blockchain download will take about 4-5 days.

Any suggestions?

Thank you. Glad to be part of this. Looks promising.

It should continue syncing after some time. If not try restarting slimcoind, this fixed it for me.

stuck at block 845745... Linux, slimcoind

an easy one ...


Xcode 8.2 hadn't been released at the time, the pre-release installed as Xcode-beta.

Re-pull from github, I just edited the slimcoin-qt.pro file:

Got rid of that error, now it stops at make:

It isn't much of a change per se, just a tweak to the QT config settings. The error report sounds promising in that webkit was removed in Qt 5.6 iirc, so it looks like you have Qt5.6/7 installed.


In the “master” branch of https://github.com/slimcoin-project/Slimcoin

See the README (c.f. my caveat about the OSX build instructions being from memory, not actual note-taking, you might want to try allowing brew to first install the Qt binaries, see if that works for you).

NB: above repos properly has “slimcoin” (last released version) as default branch. To use the most recent (as yet unreleased) version, checkout and compile the “master” branch.

I couldn't be arsed to muck about with the png used for the dmg finder window background image, it still says “Bitcoin”. Fortunately, the latest Bitcoin Core's contrib/macdeploy offers an opportunity for theft er, adaptation.

If you updated the sources to work with QTWebengine that would be great. My compilation stops at "Project ERROR: Unknown module(s) in QT: webkit webkitwidgets".

What Where is the latest source for Slimcoin OSX?

Thanks!

I used the Qt5.7 binaries from Stevan Binner's qt57 ppa for my Linux app, the Windows build uses the MXE qt binary (which is 5.7, I *think*) and I have updated the source to use QWebEngine/QWebEngineWidgets on Qt 5.7 by default. (I was trying to get a reliable foundation for tackling the halting problem with the Linux client).

The build instructions for OSX in the README are from memory. I seem to recall that it was “merely” a matter of homebrew-installed bottles and kegs. I repeatedly tried to compile Qt from source but every attempt was ultimately thwarted by a laptop crash, so I infer that in the end, I simply installed the binaries - which would be Qt5.7, I guess. I'd need to start the OS X Sierra VM to check. Which I will do sometime this week, uninstall brew, wipe its footprint and re-do the build from start, making more accurate/precise notes of each build step.

Thank you, appreciate that.

Any thoughts about webkit and webkitwidgets issue for qt 5.7?

I'll ask Ngaio if she would be kind enough to d/l the latest OSX binary to her MB and check its operation.

The OSX binary was compiled on Sierra, for Sierra and its operation has only been checked on OSX Sierra.

Well, gave it a try again, and after 38 minutes, no luck... It's most likely something on my part.

It took a few minutes on an i5 macbook pro to load. No problems with the binary.

It's i7 2Ghz, with 8GB RAM and 256 SSD. Sierra version is 10.12.1.

The newest build shall load faster, a couple of minutes but depend i think what machine do you have

I waited 15 minutes

You have to wait a little bit. I dont have any problem with loading

Also, the precompiled binary from minkiz doesn't get past the round welcome screen which says "Loading addresses". Is that meaning it's downloading the blockchain, or it loads the wallet addresses? A bit confusing

Thanks!

Hi, I am on a Mac OS, Sierra.

I got to the point where I compiled QT 5.7.1 but when I run qmake it says it doesn't find webkit and webkitwidgets. Apparently, in 5.7.1 they dropped these and replaced them with something else. Is there another way I could compile slimcoin on Mac OS?

Thank you!

Happy New Year, btw!
