This blog is about compiling the 1.7 release of Typica and the Phidgets libaries for Linux. Neal is currently working and hoping to release 2.0 sometime in the future and all this will drastically change.
Linux is a fantastic community driven operating system. It is Free and Open Source Software (FOSS), meaning someone cannot charge for the software and also provide you the source code to do what you want with it.
Typica is also FOSS. Neal provides binaries that will run in the Mac OSX world and Windows world so that you do not have to compile it. And this works for probably 90% of the people.
I like Linux for many reasons — the freeness, the freedom, the community driven development, and also the ability to re-use hardware that might not run the ever larger and slower Windows or Mac OSX operating systems. Sometime the cast away hardware from those operating system spheres still has good life left in it and it doesn’t have to be junked.
I was using the Mac Mini for my database server and am still using an Dell laptop for my Linux compile environment and roast-logger. It is a very old system, while this XT has a touch screen it is only a 32-bit CPU. If you follow my guide you will have to keep this in mind and figure out some of the 64-bitness differences. Feel free to leave those as comments to this article.
I am using Linux Mint, a debian/ubuntu based system.
You will need to update your system to the latest release. Following that, install some additional packages.
sudo apt-get update sudo apt-get upgrade (possibly reboot) sudo apt-get install libqt4-sql-psql libqt4-dev libqt4-dev-bin \ libusb-1.0-0-dev libc-dev-bin gcc-multilib g++-4.6 g++ \ libqtwebkit-dev libqtwebkit4
You need a directory for source code if you do not already have one. Make a directory called something like “src” in your home directory unless you have a preference already setup. In this directory you will setup two trees — one for Phidgets libraries and one for Typica itself.
Phidgets Library Compiling
Go ahead and open a terminal window and CD into your source (or src) directory. You need to download the latest Phidgets source into this directory. I like to browse to their page for Linux support and copy the URL and then use “wget” to fetch the file to my current directory on the system where I will compile. It saves a step or two of having to copy it later.
The current directory is here, but that could change and you can use Google or whatever search engine you like best in the future… Once you have downloaded the file, extract it, cd into the new directory, and compile the libaries. Since you have installed all the packages listed above, it should just be as simple as the instructions on the Phidgets site, also included below:
wget http://www.phidgets.com/downloads/libraries/libphidget.tar.gz tar xfvz libphidget.tar.gz cd libphidget-184.108.40.20651217 ./configure make sudo make install
If your Phidgets source directory looks differently than mine you will need to update that in the instructions below for Typica where we modify the project to include the headers for Typica.
You should “cd” up one directory to the “src” parent directory. Now download the Typica (probably 1.7) source code from the Git site. If you hover over the “Download Zip” link this should be a URL to a “master.zip”; copy the URL and use it with wget again. After downloading the zip we will uncompress it which will create many directories. We will “cd” into the first level and then into the src sub directory and we will create a backup file of one file that we will change.
wget https://github.com/N3Roaster/typica/archive/master.zip unzip master.zip cd typica-master/src cp Typica.pro Typica.pro.orig
Now we are ready to get nitty gritty. In previous blogs I was able to get around the Vi vs. Emacs vs. Nedit debate by having you use an echo command to append new statements to a file. This appears to hold true. So even though I would really love to make sure you embrace the power of the Vi side, I will again use the echo-append statement in my examples for brevity’s sake. It is very important that the you add three separate and distinct lines to the file.
echo "include(3rdparty/qextserialport/src/qextserialport.pri) INCLUDEPATH += /home/kevin/src/libphidget-220.127.116.1151217/ LIBS += -lphidget21 " >> Typica.pro
You are now ready to build the Makefile and then compile the program. First you execute the “qmake” program to create the Makefile, and then you run the “make” program to compile the code into executable binaries.
Bam! You are ready to execute the new compiled program. Unfortunately because of the libraries you will need root privilege again, so you must execute the “Typica” binary with sudo in order to run it as yourself but with root privileges.
If everything worked successfully, the program is now running and asking how to connect to your database.
