Beginner encountering difficulty building local dependencies (Mac)

Hello all,

Recently, I have been toying with the idea of writing some of my own modules. I was introduced to programming as a life-science student less than a year ago and have been looking for ways to develop C++ experience. In short, I am a total noob with a basic understanding of the command line and git.

I was following the build guide and keep running into an error building dependancies. I think it might have something to do with my CommandLineTools or libtool but, to be honest, I am not at all sure.

I installed dependancies with homebrew:

brew install git wget cmake autoconf automake libtool jq python zstd pkg-config

I cloned the repository:

git clone https://github.com/VCVRack/Rack.git
cd Rack
# Clone submodules.
git submodule update --init --recursive

I get this error when running make dep:

This error seems highly similar to this other thread, except they are on a windows machine.

Possibly my libtool is having difficulties or some path is not set up correctly. I reinstalled libtool with brew but it did not solve the issue. I also just tried running make to see if maybe this error was inconsequential, but make returned:

These files exist in dep. Not sure what is going wrong.

Has anyone else encountered this? Does anyone have ideas about what is going wrong? I have a suspicion that the solution is simple, I am just out of my depth. Or it is possible that there is no way for any of you to know whats going on without more info.

Thank you! And be warned, if you respond and help me fix this, there will likely be more noobie questions to come.

I don’t know if you omitted some steps in what you’ve told us but following along with the instructions at https://vcvrack.com/manual/Building#Building-Rack

  • When you have done cd Rack what is the output of running pwd ? (“Make sure there are no spaces in your absolute path, since this breaks the Makefile-based build system.”)

  • It seems you went from cd Rack straight to make dep and if that’s true you skipped a pretty important step:

# Clone submodules.
git submodule update --init --recursive

Thank you for your response.

I did run the submodule update, but forgot to put that in the post. Apologies!

There are no spaces in the absolute path to the Rack dir. ‘/Users/morganmiller/rareairbikeco/Rack’

Could you submit this to VCV Support so we can look into it? I believe I’ve seen the same thing on my Intel Mac.
