RNBO + JUCE app build for iOS

Hi Uasmi,

Which directory are you running your cmake command from?

The ".." in your cmake command assumes that you're in a sub-directory of our example checkout, then the -B means cmake should use the "build-ios" directory for its build scripts and artifacts.

So, if you're in the "build" directory and you've issued that command you detailed, your xcode project should be in "build-ios".

If you're in the top level checkout, remove a "." from your command, that will create "build-ios" and then your xcode project should be in "build-ios".

Could it be that you've also generated a xcode project in "build" and you're opening that instead of "build/build-ios" ?

Anyways, let me detail how I got this setup.

In a fresh checkout of the "rnbo.example.juce" project, I edit the "CMakeLists.txt" file to comment out the Plugin include (I just added a # at the start of the line):

#include(${CMAKE_CURRENT_LIST_DIR}/Plugin.cmake)

After saving that, I use Max to export my generated c++ and the rnbo library into the "export/" directory.

Then, in a terminal, I navigate to the build directory and generate the project file (the "build/" directory should be empty before I do this, also notice that I don't supply the -B option):

cd build/
cmake .. -G Xcode -DCMAKE_SYSTEM_NAME=iOS -DCMAKE_OSX_DEPLOYMENT_TARGET=15.0

Here is the output I see from that (my example project checkout is in /Users/xnor/dev/rnbo.templates/) :

-- Build files have been written to: /Users/xnor/dev/rnbo.templates/rnbo.example.juce/build

Then I open the resultant Xcode project:

open RNBO_JUCE_EXAMPLE.xcodeproj

If I look at the destinations I can see that I don't have the iOS setup installed:

After I click the "Get" and install the iOS simulators, I can see more destinations, I switch from the "install" scheme to "RNBOApp" and select one of those simulators, then click the run button:

and after that, I have the app running in an iPhone simulator.
