RNBO on Patchbox OS

maceq687 · March 19, 2026, 8:21am

The steps I took:

Basic setup
1. Installed clean Patchbox OS Bookworm ARM64 2024-04-04 image on an SD card and put it in my RPi 3B+ (I was on the bullseye based Patchbox OS before, but c74 has stopped supporting it since RNBO 1.3.0)
2. Completed the initial wizard, set jack setting, installed puredata module and set my wifi so that I could ssh to RPi
3. Updated installed packages

rnbooscquery build steps base on source repo readme

installed dependecies:
sudo apt-get -y install cmake build-essential libavahi-compat-libdnssd-dev libssl-dev libjack-jackd2-dev libdbus-1-dev libxml2-dev libgmock-dev google-mock libsdbus-c++-dev python3-pip ruby libsndfile1-dev
copied the rnbo src files from my Win machine to RPi. I have RNBO 1.4.3 installed via package manager so I took the source from %HOMEPATH%\Documents\Max 9\Packages\RNBO\source\rnbo and put it in ~/Downloads/rnbooscquery so that now I have this:
making the build:
mkdir build/
cd build/
cmake .. -DRNBO_DIR=~/Downloads/rnbooscquery/
cmake --build .
cpack

result:

The source code you copied is not for rnbooscquery, but for RNBO itself, keep it as is, but do this:

cd ~
git clone https://github.com/Cycling74/rnbo.oscquery.runner
cd rnbo.oscquery.runner
mkdir build
cd build
cmake .. -DRNBO_DIR=~/Downloads/rnbooscquery/
cmake --build .

Makes sense. Tried your suggestion, found out that conan was missing:

Installed conan (basing on the steps from the manual)
pip3 install --break-system-packages --user conan==1.61.0
, added /home/patch/.local/bin to PATH in ~/.bashrc as suggested when the conan installation completes, verified that conan works by calling it from command line.

Cleared content of the ~/rnbo.oscquery.runner/build directory and tried to make the build once more

Delete all the contents in ~/rnbo.oscquery.runner/build/ and try with this cmake command:

cmake .. -DRNBO_DIR=~/Downloads/rnbooscquery/ -DWITH_DBUS=Off

It should skip using the sdbus library, not sure what it is being used for exactly, peeking at the code, it has something to do with ‘Update Service’.

maceq687 · March 19, 2026, 9:47am

I have now renamed the directory with rnbo source files for it to have a less misleading name.

I believe the sdbus is used for the rnbo-update-service that handles updates and allows for managing the rnbooscquery versions, but it only makes sense to use it if the rnbooscquery package was coming from the c74 repository, so skipping it should be fine in the case that I make the package build manually

You have to solve the conan compiler detection issue somehow. Maybe try using the latest conan version available, or provide the config manually, see issues like these:

Conan fails to detect the compiler although `CC` and `CXX` are set

### Environment details * Operating System+version: ubuntu-22.04 * Compiler+…version: 13.1.0 * Conan version: 2.0.9 * Python version: 3.11.4 ### Steps to reproduce I am creating a Conda package of my software, as part of a Github C/I workflow. My software depends on other software (e.g.: Boost). For dependencies for which there isn't a Conda package available I use Conan to install them. Here is the idea, scattered over the various files (`.github/workflows/linux-conda.yml`, `environment/conda/build.sh`): - Create a Conda environment - Install the boa Conda package builder and execute: `conda mambabuild environment/conda --override-channels --channel conda-forge` Then `build.sh` is executed which includes: ```bash conan profile detect conan install . \ --profile=default \ --settings:host compiler.cppstd=17 \ --settings:build compiler.cppstd=17 \ --settings:build build_type=Release \ --build=missing \ --output-folder=build ``` This results in an error (see log below). Conan is not able to correctly detect the compiler. The `CC` and `CXX` variables are set, so I would expect that those are used to detect the compiler. I tried passing in the compiler explicitly, when calling `conan install`, using `--setting compiler=$CXX`, but that failed with `ERROR: 'settings.compiler' value not defined`. Maybe because the whole compiler section is missing from the profile? I think this is a bug, given that the compiler is installed and pointed to by the standard variables. If not, then my question is how to get Conan to detect the compiler correctly in this situation. I use the same conan commands to install Conan packages outside of the Conda build environment (on Linux, macOS, Windows), and those work fine. It seems that the Conda build environment is confusing Conan. Maybe because of the atypical setting of `CC` and `CXX`? ### Logs ``` 2023-08-24T16:10:09.7983374Z CC and CXX: /usr/share/miniconda/envs/test/conda-bld/lue_1692893106258/_build_env/bin/x86_64-conda-linux-gnu-cc, /usr/share/miniconda/envs/test/conda-bld/lue_1692893106258/_build_env/bin/x86_64-conda-linux-gnu-c++ 2023-08-24T16:10:09.7984827Z ERROR: Not able to automatically detect '/usr/share/miniconda/envs/test/conda-bld/lue_1692893106258/_build_env/bin/x86_64-conda-linux-gnu-cc' version 2023-08-24T16:10:09.7985898Z No compiler was detected (one may not be needed) 2023-08-24T16:10:09.7986712Z WARN: This profile is a guess of your environment, please check it. 2023-08-24T16:10:09.7987819Z WARN: The output of this command is not guaranteed to be stable and can change in future Conan versions. 2023-08-24T16:10:09.7988301Z WARN: Use your own profile files for stability. 2023-08-24T16:10:09.7988673Z Saving detected profile to /home/runner/.conan2/profiles/default 2023-08-24T16:10:09.8382941Z + conan install . --profile=default --settings:host compiler.cppstd=17 --settings:build compiler.cppstd=17 --settings:build build_type=Release --build=missing --output-folder=build 2023-08-24T16:10:10.1836158Z ERROR: 'settings.compiler' value not defined ``` Somewhat later on in the log: ``` 2023-08-24T16:10:10.3898835Z Detected profile: 2023-08-24T16:10:10.3899230Z [settings] 2023-08-24T16:10:10.3899457Z arch=x86_64 2023-08-24T16:10:10.3899668Z build_type=Release 2023-08-24T16:10:10.3900101Z os=Linux ```

type: bug priority: low stage: queue complex: low component: Build

To help us debug your issue please explain: According Conan [code](https://gi…thub.com/conan-io/conan/blob/ecbb985897633f90f532fee23685e835f9b27add/conans/client/conf/detect.py#L94), to detect the default compiler, if CC or CXX are configured and there is a valid compiler named there, then it will be used as the default one. However, when we are running cmake-cmake, CXX is configured by CMake, and it could be valuated as `/usr/bin/c++` and Conan will not be able to detect the correct compiler. I see two possibilities in this case: - Declare CC and CXX before to run cmake, forcing Conan to detect the correct compiler. - Update `_get_default_compiler` to detect the correct compiler. NOTE: This situation only affects the scenario where cmake-conan is used AND there is no default profile. #### Steps to reproduce For this example we will need to use cmake-conan, because CMake has a custom CXX. ```cmake # CMakeLists.txt cmake_minimum_required(VERSION 2.8) project(MyHello CXX) file(DOWNLOAD "https://raw.githubusercontent.com/conan-io/cmake-conan/v0.13/conan.cmake" "${CMAKE_CURRENT_BINARY_DIR}/conan.cmake") message(STATUS "CXX: $ENV{CXX}") include(${CMAKE_CURRENT_BINARY_DIR}/conan.cmake) conan_cmake_run(CONANFILE conanfile.txt BASIC_SETUP) add_library(hello hello.cpp) ``` At this point we dont care about conanfile.txt or hello.cpp. docker run -ti -v ${PWD}:/home/conan/project conanio/gcc72 mkdir build && cd build cmake .. The output shall be: > -- The CXX compiler identification is GNU 7.2.0 -- Check for working CXX compiler: /usr/bin/c++ -- Check for working CXX compiler: /usr/bin/c++ -- works -- Detecting CXX compiler ABI info -- Detecting CXX compiler ABI info - done -- Detecting CXX compile features -- Detecting CXX compile features - done -- Downloading conan.cmake from https://github.com/conan-io/cmake-conan -- Conan: Automatic detection of conan settings from cmake -- Conan: Settings= -s;build_type=Debug;-s;compiler=gcc;-s;compiler.version=7;-s;compiler.libcxx=libstdc++11 -- Conan executing: conan install /home/conan/project/conanfile.txt -s build_type=Debug -s compiler=gcc -s compiler.version=7 -s compiler.libcxx=libstdc++11 -g=cmake -- WARN: Remotes registry file missing, creating default one in /home/conan/.conan/registry.json Auto detecting your dev setup to initialize the default profile (/home/conan/.conan/profiles/default) CC and CXX: None, /usr/bin/c++ ERROR: Not able to automatically detect '/usr/bin/c++' version ERROR: Unable to find a working compiler Default settings os=Linux os_build=Linux arch=x86_64 arch_build=x86_64 build_type=Release *** You can change them in /home/conan/.conan/profiles/default *** *** Or override with -s compiler='other' -s ...s*** > Configuration: [settings] arch=x86_64 arch_build=x86_64 build_type=Debug compiler=gcc compiler.libcxx=libstdc++11 compiler.version=7 os=Linux os_build=Linux [options] [build_requires] [env] As you can see, **CXX** was detected by Conan, because CMake found /usr/bin/c++ as a valid C++ compiler.
