=============================
Hello Adam, 

Here is my [ failed ] experience to have the V8 R package on opensuse leap 15.4
.

A)
The https://cloud.r-project.org/ describes the V8 packages as ..... 

V8    Embedded JavaScript and WebAssembly Engine for R
canonical url : https://CRAN.R-project.org/package=V8

Package source:     V8_4.2.0.tar.gz

An R interface to V8: Google's open source JavaScript and WebAssembly engine.
This package can be compiled either with V8 version 6 and up or NodeJS when
built as a shared library.

SystemRequirements:     V8 engine version 6+ is needed for ES6 and WASM
support. On Linux you can build against libv8-dev (Debian) or v8-devel
(Fedora). We also provide static libv8 binaries for most platforms, see the
README for details.

Extract configure file from the V8_4.2.0.tar.gz ------>attachment
V8_4-2-0_configure_file.txt 

B) 
I tried to install V8 in opensuse leap 15.4 / R 4.2.1 using :
1) the configure file of V8_4.2.0,tar.gz distribution, and  
2) deb packages mentioned in configure file converted to rpm via  sudo alien -r
-c xxxxxxxx.deb 

Used deb files ...
basic :  
        libnode64_10.24.0~dfsg-1~deb10u1_amd64.deb
        libnode-dev_10.24.0~dfsg-1~deb10u1_amd64.deb

dependencies :
                libicu63_63.1-6+deb10u3_amd64.deb     
                libicu-dev_63.1-6+deb10u3_amd64.deb    
                libssl-dev_1.1.1n-0+deb10u1_amd64.deb
                libuv1-dev_1.24.1-1+deb10u1_amd64.deb
                icu-devtools_63.1-6+deb10u3_amd64.deb
Note : some of them conflict with leap 15.4 dist libs 

sudo zypper se -s -i -r 21

The contents of /usr/lib/x86_64-linux-gnu after intstalling the corresponding
rpm-s are 
in the attachment UsrLibx86_64-linux-gnu_lib-contents.txt

C)
Install V8_4.2.0.tar.gz  via rstudio under root authority 
[ to write on /usr/lib64/R/library]

case 1 
        > Sys.unsetenv("DOWNLOAD_STATIC_LIBV8")
        > Sys.setenv(LIB_DIR="/usr/lib/x86_64-linux-gnu")
        > Sys.setenv(INCLUDE_DIR="/usr/include/nodejs/deps/v8/include")
        > install.packages("V8",lib="/usr/lib64/R/library",dep=TRUE)

case 2  
        > Sys.setenv(DOWNLOAD_STATIC_LIBV8=1)
        > Sys.setenv(LIB_DIR="/usr/lib/x86_64-linux-gnu")
        > Sys.setenv(INCLUDE_DIR="/usr/include/nodejs/deps/v8/include")

Is it possible to have : 
i) the necessary V8 components ported to opensuse leap 15.x 
   to make CRAN V8 package installable  via rstudio, 
OR 
ii) to convert CRAN V8 to an rpm available via AutoCran repository?

]

Thanks,
