Tried calling rust_function() from the documentation and it produces an error:

What is the output of rust_sitrep()?

Hi. This is the output of rust_sitrep()

@studsttat notice the last line. From your terminal run rustup target add x86_64-pc-windows-gnu

This is my rust_sitrep after running rustup target add x86_64-pc-windows-gnu in terminal:

I'm sorry, I'm not a windows user and don't know how to further help other than rustup default stable-x86_64-pc-windows-msvc

Ilia-Kosenkov commented 9 months ago

I am puzzled as well. Let us try to debug further. Can you please run 

pkgbuild::has_rtools(debug = TRUE)

and post here the output? (You might need to install {pkgbuild} if it is not available for you)

studsttat commented 9 months ago

This is the output of pkgbuild::has_rtools(debug = TRUE):

> pkgbuild::has_rtools(debug = TRUE)
Found in Rtools 4.3 installation folder
[1] TRUE
Ilia-Kosenkov commented 9 months ago

Ok then I have no idea. Let us try something different then? If you could install {usethis} (unless it is already available), then run in some temporary folder:

usethis::create_package("build.test")
rextendr::use_extendr()

Wait till it finishes, then try

rextendr::document()

If you get any errors, please post them here. If you get here without an issue, try

hello_world()

which calls into Rust library and should print out "Hello world!".

studsttat commented 9 months ago

Ok, I tried everything so here's what I got:

When I run

usethis::create_package("build.test")
rextendr::use_extendr()

It gave me this result:

> usethis::create_package("build.test")
New project 'build.test' is nested inside an existing project './', which is rarely a good idea.
If this is unexpected, the here package has a function, `here::dr_here()` that reveals why './' is regarded as a project.
Do you want to create anyway?

✔ Opening 'D:/R/R-INT/build.test/' in new RStudio session
✔ Setting active project to '<no active project>'

I'm surprised that it was redirected into new session and it automatically creates an R project named `build.test'.

In that new session, I ran and it gave me this result:

Lastly, I ran the hello_world() and it didn't work.

Ilia-Kosenkov commented 9 months ago

You did it from an existing project (that is what usethis tells you). Could you please run it from an empty directory?

studsttat commented 9 months ago

Ok, I am sorry. So, I closed my R Project and evaluate this code

usethis::create_package("build.test")
rextendr::use_extendr()

in an empty project. After I run them:

usethis::create_package("build.test") ✔ Creating 'build.test/' ✔ Setting active project to 'C:/Users/Lenovo/Documents/build.test' ✔ Creating 'R/' ✔ Writing 'DESCRIPTION' Package: build.test Title: What the Package Does (One Line, Title Case) Version: 0.0.0.9000 Authors@R (parsed):

Read more in the help for proj_get(). ✔ Setting active project to ''

And again, it redirected into new session, an R project, named build.test in new session (new RStudio window).

After this, I tried to run rextendr::document() in the build.test() project session and I got an error.

Ilia-Kosenkov commented 9 months ago

Oh this is Rstudio toying with us. I am not a n expert in Rstudio. @JosiahParry, can you help us create a new rextendr-based package in Rstudio? If not, I will try it myself in the evening or later tomorrow.

JosiahParry commented 9 months ago

Hm. It says src/entrypoint.c does not exist. I feel like this might be a working directory issue? I've included a gif of how I would go about creating a new package using RStudio.

Another thing that I can imagine happening is that theres a suggested package that you don't have installed and {rextendr}'s code to work without it is making a bit of a bug.

What does the src/ directory look like for you?

After creating build.test, I immediately ran rextendr::use_extendr() to create source file for Rust.

But then, again, the issue still persists.

Ah yes, now it makes sense -- I actually saw a similar thing myself on my laptop, where I accidentally nuked my VS installation. It is a rust toolchain issue, see this:

note: in the Visual Studio installer, ensure the "C++ build tools" workload is selected

Check this link for installation guidelines.
