Getting Started Guide for Projucer on Raspberry Pi

[mk1]

Hi All,

Is there any guidance on how to build Projucer for a Raspberry Pi? (I assume I should be using cmake but I’m failing to make any sense out of it at the moment) I’m a complete beginner and I’m happy to follow instructions - I just can’t find any.

Thanks!

Do you really need it?
For instance I develop my projects on macOS and build on RPI/Linux without the Projucer.
But if you need it have a look in the post below.

Building Projucer on RPI4

FYI. I followed that blog in order to build the Projucer on my Raspberry Pi 4 (with Raspbian Buster). After installed the recommended packages i tested without success the following command: cd ~/JUCE/extras/Projucer/Builds/LinuxMakefile make Compiling jucer_NewProjectWizard.cpp Compiling jucer_StartPageComponent.cpp Compiling jucer_AutoUpdater.cpp Compiling jucer_CommandLine.cpp Compiling jucer_Main.cpp In file included from /usr/include/c++/8/map:61, from ../../../../mod…

Many thanks for your reply. I have just tried that and it has already got me further than I was!

I will do some more research…

[nicolasdanet]

It should compile (more or less) out of the box. If not it’s a bug!

Hi Nicolas,

Just tried it and it seems to have failed at the last hurdle:

Have you tried with make CXX=clang++ instead?

On RPI4 / juce7 branch : it works for me.

Linking Projucer - App

With gcc (Raspbian 8.3.0-6+rpi1) 8.3.0 there’s a bunch of warnings.
And it fails to link with libatomic as usual.

You need the development libraries for curl: libcurl4-openssl-dev on Debian for example.

[mk1]

Hi Nicolas, I did try make CXX=clang++ but I got and error saying:

Compiling include_juce_core.cpp
/bin/sh: 1: clang++: not found
make: *** [Makefile:401: build/intermediate/Debug/include_juce_core_f26d17db.o] Error 127

BTW, I don’t really know enough to understand your:

“With gcc (Raspbian 8.3.0-6+rpi1) 8.3.0` there’s a bunch of warnings.
And it fails to link with libatomic as usual.”

…but I’m running the latest version of Raspberyy Pi OS.

Also, see my reply to oli1 below…

[mk1]

Hi oli1,

When I read your post I tried sudo apt-get install libcurl4-openssl-dev which didn’t cause any errors but then when I tried to do the build again it didn’t change the outcome of make CXX=clang++.

[oli1]

You don’t need make CXX=clang++ unless you have clang installed, which doesn’t appear to be the case.

I just built Projucer on my Pi 4. (Unofficial steps)

• sudo apt install git cmake build-essential libx11-dev libxinerama-dev libxcursor-dev libxrandr-dev libcurl4-openssl-dev

• wget https://github.com/juce-framework/JUCE/archive/refs/heads/master.zip

• unzip master.zip && mkdir juce_build && cd juce_build

• cmake -DCMAKE_BUILD_TYPE=Release -DJUCE_BUILD_EXTRAS=TRUE ../JUCE-master

• make Projucer -j4

Building juceaide in the CMake configuration stage and building Projucer will take about 4-5 minutes.

[mk1]

I have just documented my process to post - but I can see that it looks a lot different to yours!
Very many thanks indeed for that - I will try that now…

[nicolasdanet]

I use clang since gcc doesn’t work out of the box with the provided Makefile.
At least on my RPI (since many years now).
Sorry for the noise.

[oli1]

Not at all. You’re correct. It looks like the RPI handles linking atomic differently. This should be fixable with a flag passed to make. I will confirm.

[nicolasdanet]

It seems that simply add it to the core module requirements fix it.

RaspberryPi 3 Warnings & Errors

Note that this affects all branches. First, I’m running into the same warnings as in this post: Lots of warnings like "parameter passing for argument of type ... changed in GCC 7.1" when compiling with GCC 8 . From the looks of it passing -Wno-psabi into all projects could fix the issue, but blanket warning disabling kind of sucks… so I’ll leave that up to you. As for the errors: When unit tests are enabled, the DSP module tests SIMDRegister in an environment that doesn’t apply. We need to …

[mk1]

Sorry, wrong box! This is what I meant to post:

This is a script which will install Projucer on a newly created Raspberry Pi image. It is basically just what Oli posted, placed into a script file. Many thanks to Oli!
