Swift "Build" not working on Ubuntu 16.04 - swift

I have recently installed swift by following the commands described on https://github.com/PerfectlySoft/PerfectDocs/blob/master/guide/gettingStarted.md
Installation seems to be OK.
swift --version is python-swiftclient 3.2.0
but when go swift build it says "no such command: build"
What am I supposed to do?

"python-swiftclient" has nothing to do with Apple's Swift, it's a library for the OpenStack Object Storage API.
To install Apple's Swift on Ubuntu, you need to follow the instructions detailed at swift.org as told on the Perfect document you're referring: "After you have installed a Swift 3.0 toolchain from Swift.org..."
You will have to install dependencies with:
$ sudo apt-get install clang libicu-dev
then extract the .tar.gz file downloaded from swift.org and set the PATH to the executable - all of this is explained on the site.

Mongodump/OpenSSL - "image not found" error

I recently updated macOS to Catalina and mongodump is no longer working. I've updated
dyld: Library not loaded: /usr/local/opt/openssl/lib/libssl.1.0.0.dylib
Referenced from: /usr/local/opt/mongodb#3.6/bin/mongodump
Reason: image not found
I see a few questions out there such as this one: dyld: Library not loaded: /usr/local/opt/openssl/lib/libcrypto.1.0.0.dylib. This is the accepted response:
brew update && brew upgrade
brew uninstall openssl
brew install https://github.com/tebelorg/Tump/releases/download/v1.0.0/openssl.rb
However, I get this error when trying to install version 1.0.0:
Error: Calling Non-checksummed download of openssl formula file from an arbitrary URL is disabled! Use 'brew extract' or 'brew create' and 'brew tap-new' to create a formula file in a tap on GitHub instead.
Is there any way around this? I'm not really sure where to go from that message.
You can check which version of Homebrew is installed by running brew --version
You can use my previous response to implement how Homebrew now suggests it. Or if you want to use previous version of Homebrew to use these commands then follow this:
Go to Homebrew folder cd /usr/local/Homebrew/
Checkout to the previous version by running git checkout 2.3.0
To install OpenSSL HOMEBREW_NO_AUTO_UPDATE=1 brew install https://github.com/tebelorg/Tump/releases/download/v1.0.0/openssl.rb

How to run swift and libDispatch on ARM (Raspberry Pi)

The aim is to run swift and libDispatch on a Raspberry Pi 3. I’m using Ubuntu Core 16.04
Where I’m at: I’ve tried to get SR-397 (https://bugs.swift.org/browse/SR-397) to compile - it is a minimal Swift libDispatch example.
The projects for this SR are here: https://github.com/sheffler/gcd4 and here: https://github.com/sheffler/CDispatch
When I try to compile the gcd4 project, I get this error: “error: Empty manifest file is not supported anymore. Use swift package init to autogenerate.”
I assumed the error message was due to the empty Package.swift file, so then I copied the Sheffler CDispatch project to https://github.com/tree700/CDispatch and added a Package.swift file. I still get the same error and haven't been able to get past it.
By way of background, I’m using a precompiled download of Swift 3.1.1 from https://github.com/uraimo/buildSwiftOnARM, and have installed Ubuntu libdispatch0 and libdispatch-dev packages and dependencies on my system. The swift compiler and Swift Package Manager are working fine,
I’d love to get this going, I use Dispatch on OS X, and it makes concurrency a breeze. Thanks
The answer was simple... the extra information required is in the associated blog. To obtain and install Swift 3.1.1 go to https://www.uraimo.com/2017/09/06/A-small-update-on-Swift-for-raspberry-pi-zero-1-2-3/
Which says to do this...
sudo apt-get install git cmake ninja-build clang-3.8 python uuid-dev libicu-dev icu-devtools libbsd-dev libedit-dev libxml2-dev libsqlite3-dev swig libpython-dev libncurses5-dev pkg-config libblocksruntime-dev libcurl4-openssl-dev autoconf libtool systemtap-sdt-dev
sudo update-alternatives --install /usr/bin/clang++ clang++ /usr/bin/clang++-3.8 100
sudo update-alternatives --install /usr/bin/clang clang /usr/bin/clang-3.8 100
After that, there is the the usual process of decompressing the compressed project file and adding the usr/bin directory into one's path (or run swift, swift etc from inside usr/bin)
Note: I also had to install the package libpthread-workqueue-dev. If running on Raspbian, requires an upgrade to Stretch .
———
By the way, I posted the SO question when using a Raspberry 3. In fact, I was on an early Pi model B when I got this working. The Pi 3 will soon have Swift also. Here is a simple Swift program to test libdispatch:-
import Foundation
import Dispatch
let queue = DispatchQueue(label: "queueName")
let workItem = DispatchWorkItem(qos: .userInitiated, flags: .assignCurrentContext) {
print("Hello")
}
queue.async(execute: workItem)
DispatchQueue.main.async {
print("Hello2")
}
dispatchMain()

Problems with Swift 3 dev toolchain

I have installed Swift from the dev downloads and am currently using
swift-DEVELOPMENT-SNAPSHOT-2016-04-12-a-ubuntu14.04
When I run
swift build
I get this terse message:
error: invalid inferred toolchain
I have had this configuration running earlier this week, but I seem to have broken something. Any suggestions on how to proceed?
Did you install the required dependencies?
sudo apt-get install clang libicu-dev

installing ruby 1.9.3 in michael hartl's ruby on rails tutorial

I'm working on Michael Hartl's ruby on rails tutorial http://ruby.railstutorial.org/ruby-on-rails-tutorial-book#sec-development_tools.
I installed Git, updated my OS to 10.8.2 and downloaded XCode 4.5.2.
when I type in
rvm install 1.9.3
this long thing comes up...
Ruby (and needed base gems) for your selection will be installed shortly.
Before it happens, please read and execute the instructions below.
Please use a separate terminal to execute any additional commands.
Notes for Mac OS X 10.8.2, Xcode 4.5.2.
For JRuby: Install the JDK. See http://developer.apple.com/java/download/ # Current Java version "1.6.0_26"
For IronRuby: Install Mono >= 2.6
For Ruby 1.9.3: Install libksba # If using Homebrew, 'brew install libksba'
For Opal: Install Nodejs with NPM. See http://nodejs.org/download/
To use an RVM installed Ruby as default, instead of the system ruby:
rvm install 1.8.7 # installs patch 357: closest supported version
rvm system ; rvm gemset export system.gems ; rvm 1.8.7 ; rvm gemset import system.gems # migrate your gems
rvm alias create default 1.8.7
And reopen your terminal windows.
Xcode and gcc:
Right now Ruby requires gcc to compile, but Xcode 4.2 and later no longer ship with gcc. Instead they ship with llvm-gcc (to which gcc is a symlink) and clang, neither of which are supported for building Ruby. Xcode 4.1 was the last version to ship gcc, which was /usr/bin/gcc-4.2.
Xcode 4.1 and earlier:
- Ruby will build fine.
Xcode 4.2 and later (including Command Line Tools for Xcode):
- If you have gcc-4.2 (and friends) from an earlier Xcode version, Ruby will build fine.
- If you don't have gcc-4.2, you have two options to get it:
* Install apple-gcc42 from Homebrew
* Install osx-gcc-installer
Homebrew:
If you are using Homebrew, you can install the apple-gcc42 and required libraries from homebrew/dupes:
brew update
brew tap homebrew/dupes
brew install autoconf automake apple-gcc42
rvm pkg install openssl
Xcode 4.2+ install or/and Command Line Tools for Xcode is required to provide make and other tools.
osx-gcc-installer:
If you don't use Homebrew, you can download and install osx-gcc-installer: https://github.com/kennethreitz/osx-gcc-installer.
Warning: Installing osx-gcc-installer on top of a recent Xcode is known to cause problems, so you must uninstall Xcode before installing osx-gcc-installer. Afterwards you may install Xcode 4.2+ or Command Line Tools for Xcode if you desire.
** NOTE: Currently, Node.js is having issues building with osx-gcc-installer. The only fix is to install Xcode over osx-gcc-installer.
Press 'q' to continue.

Originally I had to get homebrew and
brew install libksba
but I did that already and it works. That leads to "Xcode and gcc:" and everything below it.
So, I have homebrew, and the following three commands work:
brew update
brew tap homebrew/dupes
brew install autoconf automake apple-gcc42
But when I try
rvm pkg install openssl
this is what happens
Fetching openssl-1.0.1c.tar.gz to /Users/adamzerner/.rvm/archives

Please note that it's required to reinstall all rubies:
rvm reinstall all --force
Updating openssl certificates
Error running 'update_openssl_certs', please read /Users/adamzerner/.rvm/log/openssl.certs.log
And this is what happens when I try what it says...
Adam-Zerners-MacBook-Pro:~ adamzerner$ rvm reinstall all --force
Adam-Zerners-MacBook-Pro:~ adamzerner$
some other information...
I don't see a .rvm folder under adamzerner, so I can't read what it tells me to (not that I would understand what I'd be reading anyway).
It seems that I have 1.8.7 installed:
Adam-Zerners-MacBook-Pro:~ adamzerner$ ruby -v
ruby 1.8.7 (2012-02-08 patchlevel 358) [universal-darwin12.0]
So... to summarize... when I try to run
rvm install 1.9.3
I get the gcc/Xcode problem. To fix that it says to download apple-gcc42 from Homebrew. When I do that, I get a problem after doing
rvm pkg install openssl
The problem being that I need to reinstall all rubies. When I do that:
rvm reinstall all --force
it seems that nothing happens.
Thanks in advance to anyone willing to help me with this problem!
EDIT: I forgot to say this before. For the "long thing" up above, when I press q to continue, this is what happens...
Searching for binary rubies, this might take some time.

Adam-Zerners-MacBook-Pro:~ adamzerner$
I've successfully downloaded Ruby 1.9.3 now!
I think the problem was that I hadn't downloaded Command Line Tools from XCode. See http://robots.thoughtbot.com/post/27985816073/the-hitchhikers-guide-to-riding-a-mountain-lion
note that for whoami, it's using the backtick key, which is right above the tab key. It is NOT using quotes.
After I downloaded Command Line Tools, I then typed in rvm install 1.9.3. I got the same "long thing" as before, but at that point I had everything I needed, so I just pressed q to continue, and ruby 1.9.3 was successfully installed!
note: although it was successfully installed, when I typed ruby -v, it still said it was 1.8.7 even though it wasn't. However, after closing and reopening the terminal, it then said that the version was indeed 1.9.3.

Thus, I cannot use TERMINAL to install YAJL to get my app to build. Help needed.
P.S.
In terminal preferences, Shells Open With is either /usr/bin/login or /bin/bash
YAJL is supposedly installed at /Users/Rex
I am using OSX 10.6.2
Solution was that my OS is snow leopard and the version of Xcode i was using was not. Re-installing the proper xcode update solved it.
