Failure to install package on OSX

[Ic3fr0g]

Here's what I tried

> install_github("jmp75/rClr", build_vignettes=TRUE)
Downloading GitHub repo jmp75/rClr@master

Ok. So here's how far I got -

brew install mono
Might have linking errors, in which case I Super-Usered it based on reading several different links.
sudo chown -R (username-here) /usr/local/share/man/man5
Similarly, brew install pkg-config and brew install glib

However reinstalling in R still threw an error -

Oh btw Mono JIT compiler version 5.0.1.1 (2017-02/5077205 Wed May 31 14:47:04 BST 2017)

Thanks for the information, this is comprehensive. I do not have access to MacOS so not sure, but what seems to be likely is that the .Net assembly ClrFacade.dll is not present in the 'inst' folder, so probably a compilation failure.
I have been trying to refresh rClr on a branch, after a lull due to changing daytime job tech stack. I should be in a position to merge to master soon, but I need to do a few more checks.

@jmp75 that ClrFacade.dll line isn't doing anything as it's commented out. It's from Makevars.in

The error is actually

cp: illegal option -- u

which is valid on Linux but not macOS.

@Ic3fr0g I'd also try installing Mono 3.12 as this was the most recent version that I could get working

Removing -u from Makevars.in produces the following build failure:

Hi @scottmmjackson!

** testing if installed package can be loaded
Assembly '/Library/Frameworks/R.framework/Versions/3.3/Resources/library/rClr/libs/ClrFacade.dll' doesn't have an entry point.
Error : .onLoad failed in loadNamespace() for 'rClr', details:

Stuck at the same place with Mono v6.12.0.18 and R v4.2.2. Did you manage to make it work somehow?

[scottmmjackson]

Sadly no

[king-of-poppk]

Looks very similar to #49.
