Compiling X 13ARIMA SEATS from Source for Ubuntu - christophsax/seasonal GitHub Wiki

Since version 1.2, seasonal relies on the x13binary package to access prebuilt binaries of X-13ARIMA-SEATS. No manual compilation needed anymore!

This is a step-by-step guide on how to compile the HTML version of X-13 for Ubuntu, using gfortran, which is part of the Ubuntu installation. It has been tested on an Ubuntu 14.04.2 LTS server, but should be easily adaptable to other Linux versions. Parts of this post have been borrowed from [askubuntu](http://askubuntu.com/questions/444354/how- do-i-install-x13-arima- seats-for-rstudio-from-source).

1. Download the source code package x13ashtmlsrc_V1.1_B19.tar.gz from the Census website.

    wget http://www.census.gov/ts/x13as/unix/x13ashtmlsrc_V1.1_B19.tar.gz
   

   (If you want to install the non-html version, e.g., for the use in Python's statsmodels, use the x13assrc_V1.1_B19 file and drop the html from the filenames below.)

2. Unpack the file to a new directory. Then, go there:

    mkdir myx13
    tar zxvf x13ashtmlsrc_V1.1_B19.tar.gz -C myx13
    cd myx13
   

3. In the April 2, 2015 version, there are misspellings of filenames. Make sure all filenames are lower case. I had to change Acf.f to acf.f and ADJREG.f to adjreg.f.

    mv Acf.f acf.f
    mv ADJREG.f adjreg.f
   

   In the newer source file x13ashtmlsrc_V1.1_B19.tar.gz, these already existed as lowercase-named files so

    rm Acf.f ADJREG.f
   

   also worked.

4. Compile the code:

    make -f makefile.g77
   

   While the filename ends in g77, it does invoke the gfortran compiler.

5. You can test your compilation:

    ./x13ashtml
   

   If everything went fine, you should get the following error that proves the working of your binary file:

    X-13ARIMA-SEATS Seasonal Adjustment Program
    Version Number 1.1 Build 19
    Execution began  Jul 17, 2015  07.28.47 
   
    ERROR: Must specify either an input specification file name
           (-i infile or infile) or an input metafile name (-m metafile).
   
           See Section 2 of the X-13ARIMA-SEATS Reference Manual for more
           information on how to run X-13ARIMA-SEATS.
   

6. You can move the newly created x13ashtml binary file to anywhere you want and configure it for the use in seasonal as described in the vignette.
