How to Install nim on Ubuntu 16.04

Overview

In this tutorial we’ll learn how to install Nim on Ubuntu 16.04. We will install Nim from Ubuntu repository and also install nim from source.

Nim is :

a systems and applications programming language. Statically typed and compiled, it provides unparalleled performance in an elegant package.

Nim Provides :

  • High-performance garbage-collected languag
  • Compiles to C, C++ or JavaScript
  • Produces dependency-free binaries
  • Runs on Windows, MacOS, Linux and more

Install nim From Repository

Nim is available on Ubuntu 16.04 repository. To install Nim we can run command below


$ sudo apt-get update
$ sudo apt-get install -y nim

Now we can check Nim version installed with contents below:


$ nim -v
Nim Compiler Version 0.12.0 (2015-11-02) [Linux: amd64]

active boot switches: -d:release

Hello Nim

Let’s create hello world application for Nim. Create new file called hello.nim with contents below:


echo "Hello Nim! - howtodojo.com"

Compile the source code using command below


$ nim c hello.nim 
Hint: system [Processing]
Hint: hello [Processing]
CC: hello
CC: system
Error: execution of an external compiler program 'gcc -c  -w  -I/usr/lib/nim -o /home/ubuntu/nimcache/hello.o /home/ubuntu/nimcache/hello.c' failed with exit code: 32512

/bin/sh: 1: gcc: not found

We still get error since we don’t have gcc installed. Yes, nim rely on c / c++ compiler to compile.

Install gcc using command below


$ sudo apt-get install gcc

Now let’s recompile our hello.nim source code.


$ nim c hello.nim
Hint: system [Processing]
Hint: hello [Processing]
CC: hello
CC: system
Hint:  [Link]
Hint: operation successful (9852 lines compiled; 0.910 sec total; 14.148MB; Debug Build) [SuccessX]

Source code compiled sucessfully. The binary file name is hello. We can check the file type using file command.


$ file hello
hello: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.32, BuildID[sha1]=fe9a2d66209c2adb082ae63e15fc35e8f991a322, not stripped

We can see above that hello is a ELF / Linux binary file.

Now let’s execute the hello application.


$ ./hello 
Hello Nim! - howtodojo.com

The application run successfully.

Install nim From Source

As you can see above, Nim version shipped with Ubuntu 16.04 is 0.12.0.

At the time of this writing, the latest stable version of Nim is 0.17.2. In this section we’ll learn how to install nim from source.

We can download the latest version of Nim from Nim install Unix page.

Download nim source code using wget.


$ wget -c https://nim-lang.org/download/nim-0.17.2.tar.xz

Download sha256 file that contain hash for nim source code file. We will use this file to ensure the integrity of nim source code.


$ wget -c https://nim-lang.org/download/nim-0.17.2.tar.xz.sha256  

Now let’s check nim source code integrity using sha256sum command


$ sha256sum -c nim-0.17.2.tar.xz.sha256
nim-0.17.2.tar.xz: OK

If should output OK as shown below. If not then you will need to redownload nim source code.

Extract nim source code using command below.


$ tar xJf nim-0.17.2.tar.xz

Go to extracted directory


$ cd nim-0.17.2    

Run commands below to build nim and tools. We assume that you already install gcc before compiling Nim.


$ ./build.sh
$ bin/nim c koch
$ ./koch tools        

Install nim to /opt directory


$ sudo ./install.sh /opt

Check Nim version on opt


$ /opt/nim/bin/nim -v

Summary

In this tutorial we learned how to install Nim from Ubuntu repository. We learned how to compile Hello Nim! source code to test our installation.

We also learned how to install Nim from source code. Have fun with Nim!
