Compiling Ctrlr: For Windows 10

Ported from a wonderfully crafted PDF by author Sjoerd W Bijleveld

• This document describes the steps I took to compile Ctrlr with Visual Studio 2019 on Windows 10.
• Disclaimer: I’m primarily a Mac/Apple user, so I’m probably not able to answer typical technical Windows/Visual Studio questions.
• Below is the About Ctrlr window of the compiled version.

The publishing date of this version is: April 8, 2021 My version of Visual Studio 2019 is: 16.9.4 and I installed it for the following 2 workloads: • Universal Windows Platform development; • Desktop development with C++. I did use Windows 10 Pro English running virtual on my iMac with VMWare Fusion. I did use a fresh (but rather old) installment of Windows 10 and before I could install and run Visual Studio 19, I had to do every update available for Windows 10. (My copy of Windows 10 dates back from August 2015 and was originally probable too old.)

Download the Ctrlr source files

• The first thing you have to do of course is download the latest master from the Ctrlr Github[https://github.com/RomanKubiak/ctrlr]. First step you have to after downloading is unzipping boost.zip
• You will find this file in ..\ctrlr-master\Source\Misc\boost\
• Just unzip it and do nothing further.

Run shell scripts when compiler complains about "final"

• If the compiler complains you need to run shell scripts, otherwise you're lucky and may skip this part and continue with the section Using the Projucer app!
• I refer to this comment of Roman Kubiak: [https://github.com/RomanKubiak/ctrlr/commit/c1f67d2f4033cb9f5dd20a123854fcddcd99b81d]
• This means that part of compiling Ctrlr is first running so called shell scripts (files with extension .sh).
• These scripts only run in a Unix-like environment and from the terminal.
• Cygwin64 does provide this functionality for Windows, so first thing I had to do was installing Cygwin64: [https://cygwin.com]
• In the Ctrlr folder I found 2 .sh files. I decided to run both, because both seem to address the “final” issue.

Running the shell scripts

• Open Cygwin64 Terminal. Type cd (without the quotes) and drag your Ctrlr folder into the terminal window and hit ENTER. This way you set the terminal to the Ctrlr directory.
• Next type ‘bash’, again without the quotes, and drag the script file ‘remove_finals_from_JUCE.sh (located in the scripts folder) into the terminal window and hit ENTER. A long list of files scrolls by.
• The window looks like this:

• Do the same with the script file remove_final.sh found in the JUCE directory.
• I’m not sure if this is really needed, but it seemed not doing any harm.

Using the Projucer app

• Projucer is needed as an intermediate step to load the Ctrlr project properly into Visual Studio.
• So after you have downloaded and installed JUCE go to the JUCE folder, where you’ll find Projucer.exe.
• Start the program.

Building Ctrlr

• Before you export to Visual Studio make sure you set the right global paths.
• Path to JUCE is the path to the Juce folder in your ctrlr-master folder.
• Path to JUCE Modules is the path to the modules folder inside the Juce folder of the ctrlr-master folder.

• Now choose File>Open... and pick the file: \ctrlr-master\Ctrlr.jucer
• This file contains all the (source) files you need to build Ctrlr. Click on the export button of Projucer.
• Visual Studio will start and the Ctrlr project is loaded.

Building the Ctrlr_SharedCode

• First step in building is to build the Ctrlr_SharedCode.
• Before you can do the actual building you have to adjust some settings in Visual Studio.
• The first one is the set the Preferred Build Tool Architecture to 64-bit (x64).

• Choose option Properties and in the Properties window choose Advanced and set the architecture:

• The second setting has to do with the so called C/C++ Output File.
• Before you set this, make sure you have selected the Ctrlr_SharedCode item in the Solution Explorer side pane, because the setting will affect this item.

• Now go again to Project>Properties (the same menu option when setting the Build Architecture, see above) and choose C/C++> Output Files>Program Database file Name, and choose (or in case of not showing the text, type): <inherit from parent or project defaults>

• This has to be done because of the problem discussed here.
• Click OK and set the build to Release and x64, you may choose otherwise:

• Next start the actual building:

• After a few minutes and many warnings, mostly of type C4459, if all is well the build succeeds. Next task is building the Ctrlr_StandalonePlugin project.

Building Ctrlr_StandalonePlugin

• In fact the procedure for building this plugin is pretty much the same as for the Ctrlr_SharedCode project.
• First you select in the Solution Explorer the Ctrlr_StandalonePlugin item and then make sure that firstly the Preferred Build Tool Architecture is set to 64-bit (x64) as explained in the build for Ctrlr_SharedCode section above and secondly the Program Database File Name for the C/C++ Output File is set to <inherit from parent or project defaults>
• After this settings you can build the plugin, which takes a rather long time, so be patient.
• If again all is well, the build succeeds.
• You will find the generated Ctrlr-x64.exe in: ..\ctrlr-master\Builds\VisualStudio2019\x64\Release\Standalone Plugin\
• So this is the build for CTRLR 64-bit. Building for 32-bit does succeed only in Debug mode, but this build gives problems when running on a computer without Visual Studio installed or the proper redistributable VC_redist.x86 for the 32-bit architecture installed.
• (See my post further down in this thread about running the application without an installment of Visual Studio.)

About this build

• I did test the application on my laptop with Windows 7, using a simple USB MIDI interface.
• The interface was connected to my Kurzweil K2500R.
• The panel for this instrument loaded OK and the K2500R responded as expected to the various sysex messages send from this panel.
• I will test this build further and keep you of course posted about my findings.
