Hello,
I am reviewing this package for submission at JOSS. When I tried to run the example.R file from the bridgestan/R folder, I get the following error:

Error in .C("bs_model_construct_R", as.character(data), as.integer(seed),  : 
  "bs_model_construct_R" not available for .C() for package "bernoulli_model"

My guess is that it originates here

bridgestan/R/example.R

Line 7 in 7267e83

model <- StanModel$new("../test_models/bernoulli/bernoulli_model.so", "../test_models/bernoulli/bernoulli.data.json", 1234)
,
is something missing in this call

bridgestan/R/R/bridgestan.R

Line 42 in 7267e83

ret <- .C("bs_model_construct_R",
?

Hi @saumil-sh -

Can you share a bit more about how you downloaded bridgestan and what commands you ran before receiving this error? We had an issue in the R example (#121) which was fixed recently, but if you downloaded one of the .tar.gz from the GitHub releases page I do not believe it would have been updated yet.

I had a look at #121 before posting this and I belive it is a different issue.

I followed the documentation and used git clone --recurse-submodules https://github.com/roualdes/bridgestan.git.
Here is the relevant lines of the output of my git log

commit 6dd7d3a8a80b9027145fb20d230aa86e5fcf99df (HEAD -> main, origin/main, origin/HEAD)

    Python: Warn if user has 5+ copies downloaded in .bridgestan (#128)

I am on Mac M1 running Ventura 13.4 and tested the installation according to the documentation running make test_models/multi/multi_model.so from the root directory of the repo.

Next, I created a mamba/conda environment using mamba create -n stan -c conda-forge and installed r-base and radian. Then I followed the relevant documentation to install the R bridgestan package. Here is the relevant version information:

$ mamba --version     
mamba 1.4.2
conda 23.3.1

$ mamba list | grep r-base
r-base                    4.3.0                h4b3f977_1    conda-forge

$ mamba list | grep radian
radian                    0.6.6              pyhd8ed1ab_0    conda-forge

I am aware of 2 ways of running an R script, one using Rscript example.R and another source("example.R") from radian both threw the same error mentioned in the first post in this thread.

Please let me know if I missed any information.

Did you build the bernoulli_model library before running the example? If you were able to build the multi_model.so file your installation is most likely working, but you may need to build the specific model the example is using first

bridgestan/R/example.R

Lines 1 to 3 in 7267e83

# Before running this:
# - In the terminal, run `make test_models/bernoulli/bernoulli_model.so` from inside the bridgestan folder
# - In R, make sure you are in the directory bridgestan/R

I forgot to mention this. I did run make test_models/bernoulli/bernoulli_model.so and if I run it again it says:

$make test_models/bernoulli/bernoulli_model.so
make: 'test_models/bernoulli/bernoulli_model.so' is up to date.

Should I "remake" it using the make -B flag?

@WardBrian

That all seems correct, then.

Could you try running the following command:
nm test_models/bernoulli/bernoulli_model.so | grep " bs_"

This should print out the names of the functions available in bernoulli_model. It should be the case that bs_model_construct_R is on this list, but it is good to check

Can you share your C++ compiler version and how you installed it (xcode, brew, mamba, etc)? The output of nm suggests it is mangling the C function names with a leading underscore. I've known of some macos compilers to do this, but it hasn't previously come up for us in this project.

You may be able to delete the model library and then use CXXFLAGS=-fno-leading-underscore make test_models/bernoulli/bernoulli_model.so to fix this (to be verified either with nm or with the example script), but it would be great to understand why this is occuring/why we haven't encountered it with other Macs we've used

It may also be worthwhile to test either the Python or Julia example if you are able to - it's possible the issue is that the build of R you installed is not properly handling the leading underscores which can appear in macos libraries

I will share my C++ compiler and relevant setup and I try your suggestions when I get to it tomorrow.

Python and Julia examples ran as expected.
python:

$python example.py
This model's name is bernoulli_model.
It has 1 parameters.
log_density and gradient of Bernoulli model: (-27.455880681398384, array([-7.67408425]))

julia:

$julia -e 'using Pkg; Pkg.activate(".."); include("example.jl")'
  Activating project at `/Volumes/shah/projects/reviews/bridgestan/bridgestan`
This model's name is bernoulli_model.

Hey,
Here is relevant information about my setup:
When I try xcode-select --install It directs me to I updated xcode using System Settings > Software Update, and that is how I updated it just before cloning the repo.

$xcode-select --version                    
xcode-select version 2397.

clang and make were installed as the dependency in the mamba environment I created.

$clang --version  
clang version 16.0.5
Target: arm64-apple-darwin22.5.0
Thread model: posix
InstalledDir: /Users/shah/mambaforge/envs/stan/bin

$clang++ --version
clang version 16.0.5
Target: arm64-apple-darwin22.5.0
Thread model: posix
InstalledDir: /Users/shah/mambaforge/envs/stan/bin

$make --version
GNU Make 4.3
Built for arm64-apple-darwin20.0.0

The xcode command line tools provide other compilers.

$g++ --version
Apple clang version 14.0.3 (clang-1403.0.22.14.1)
Target: arm64-apple-darwin22.5.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin

I will rebuild with no leading underscore flag and let you know how it goes.

I ran make clean and then built the multi model again. There are 43 warnings generated, I am putting them here in case it may be useful.

Python and Julia examples ran as expected.

Because of this, I believe the issue is with R, not with the compiler, since all three languages will be using the same dylib. The Python and Julia clients both request the function names without the leading underscore, and their standard libraries seem to know to add it. But R isn’t, at least not the build from conda (I know several Mac/R users who this problem has not surfaced for).

Just to confirm I’d like @roualdes to check (using nm) if the symbols on his Mac have the leading underscore. If so we can be fairly confident that the issue is not with compilation but in the R runtime

I tried R 4.2 and 4.3 on Platform: x86_64-apple-darwin20 (64-bit), Running under: macOS Monterey 12.6.6 with both the R console and radian and the R example works as is, for me.

As far as I understand this, we've narrowed the issue down to either a aarch64-apple-darwin20.0.0 issue and/or a mamba/conda issue. I can't do anything about not having an M1 and I'm hesitant to install mamba/conda, because I don't know how to sandbox the install.

@saumil-sh would you mind trying to install R outside of a mamba/conda environment, and then trying the R example again?

Hi,
I installed an R instance outside mamba using brew install r

$R --version      
R version 4.3.1 (2023-06-16) -- "Beagle Scouts"
Copyright (C) 2023 The R Foundation for Statistical Computing
Platform: aarch64-apple-darwin22.4.0 (64-bit)

Made sure Bernoulli example is compiled, R6, and bridgestan are installed.
et voilà

r$> source("example.R")
[1] "This model's name is bernoulli_model."
[1] "This model has 1 parameters."
[1] "log_density and gradient of Bernoulli model: -8.8324194103925, -4.27513683401048"

So, the conda distribution of the R is the culprit here.

This is good to know. Thanks @saumil-sh for discovering and helping us find the root of this issue.

What do you all think is the appropriate action item from this? Add a note in the install doc for R? Do nothing until this issue surfaces again? Other?

I can file an issue against https://github.com/conda-forge/r-base-feedstock, which is where the Conda recipe is maintained

A note in the documentation is certainly a good idea until this is resolved.
