Install IO on Linux

Generally on my development machine when I compile from source I like to install locally to my home directory rather than system wide. This way sudo privileges are not needed plus I just like the idea of keeping these items close to home.
First Io requires the cmake build system so make sure that is available.

$ sudo apt-get install cmake

Next download and extract the source code.

$ wget --no-check-certificate 

http://github.com/stevedekorte/io/zipball/master -O io-lang.zip 

$ unzip io-lang.zip
$ cd stevedekorte-io-[hash] 

Io provides a build script, however it is setup to install the language to /usr/local. Since I want it to go in $HOME/local you just need to modify that file. Here is a quick one liner:

$ sed -i -e 's/^INSTALL_PREFIX="\/usr\/local/INSTALL_PREFIX=

"$HOME\/local/' build.sh

Now build and install.

$ ./build.sh
$ ./build.sh install

Since we are installing into a location our OS doesn’t really know about, we need to configure a few paths.

$ vim ~/.bashrc
export PATH="${HOME}/local/bin:${PATH}"
export LD_LIBRARY_PATH="${HOME}/local/lib:${LD_LIBRARY_PATH}"
 
# You might want these too
export LD_RUN_PATH=$LD_LIBRARY_PATH
export CPPFLAGS="-I${HOME}/local/include"
export CXXFLAGS=$CPPFLAGS
export CFLAGS=$CPPFLAGS
export MANPATH="${HOME}/local/share/man:${MANPATH}"

Lastly restart your shell and type ‘io’ and Enjoy!
