Download Xcode11.xip from the Apple Developer website ( ) - requires registration (free) at developer.apple.com website.

Unzip and install Xcode11.

Download CommandLineToolsforXcode11.dmg from the Apple Developer website ( ).

Regardless of Xcode version, older OS () X SDK is not needed to build with support for older versions of macOS, but support for older macOS versions has to be explicitly turned on during the build of OpenCPN, wxWidgets and other libraries as described below.

There are required development tools that can be installed via Homebrew ( ) (or similarly from MacPorts, but it is unsupported and untested).

Add the gettext tools to your PATH environment variable using.

And either restart Terminal.app or reload your environment using.

If you are building OpenCPN with SVG support (default), Cairo library is needed, install it using.

Additionally, to support all the features of the wxSVG component, libexif should be installed using.

If you are building OpenCPN with extended archive support (default, required to download and unpack up to date GSHHG basemaps and pilot charts using the chart downloader plugin), libarchive library is needed, install it using.

Read following note - install only if necessary - To produce binaries fully compatible with older macOS versions on newer macOS, libarchive must instead of from Homebrew, be built as follows.

OpenCPN is built upon wxWidgets, a package providing a cross-platform UI SDK.

But to get results fully compatible with the official OpenCPN builds, which retain compatibility with macOS Mavericks (10.9) and newer, wxWidgets must be version 3.1.2 built manually as follows: Download wxWidgets-3.1.2.tar.bz2 from: Unzip and move wxWidgets-3.1.2 folder to Desktop.

To create.pkg files for plugins, download the Packages tool from ( ).

Install Packages.dmg by double-clicking the file and following the instructions - no need to open Packages.app as the installer configures the necessary command line tools for Packages.

If everything is installed OK, you should get the message Your system is ready to brew.

Officially OpenCPN is built from the command line, but its also possible to use Apples Xcode IDE for development.

Regardless of which method we choose, the first steps are the same: Get the OpenCPN source.

Create the build directory, where our local builds will take place, so that we dont work directly in the source tree.

Open the OpenCPN.xcodeproj file in Xcode, and use the Build, Run, Debug, etc features as normal.

To use the Run action you need to build the OpenCPN target rather than the default ALLBUILD target.

Everything from usrlocalbin gets packaged into your DMG which is not desirable.

To avoid this, change the install location with cmake as follows.

Some developers have reported that the install step copies a redundant set of the wxWidgets dynamic library into the install directory, causing OpenCPN to fail.
