Hi @hellomissingdata, can you check your Makevars.win file using

file.edit(file.path(Sys.getenv("HOME"), ".R", "Makevars.win"))

and share what the contents are? I think there could be some duplicate entries.

[SteveBronder]

@jgabry can we merge #857 ? I think that should help here

[hellomissingdata]

Hi, Jonah, Thank you for the suggestion. You are absolutely correct. I have multiple entries there. Now I wiped them. It worked finally. Thanks!

Yeah that's fine by me. I usually let @bgoodri merge RStan stuff but I'll reply to the PR and ask if if he's ready. I couldn't quite tell from his comments on the PR if he's ready to merge it yet.

@hellomissingdata Great, glad it's working! Did you remove everything or just the duplicate? I think currently on Windows this line should work well:

CXX14FLAGS = -O3 -g0 -Wno-ignored-attributes -Wno-deprecated-declarations

The -O3 should speed things up a bit and the Wno-** lines should silence some messages during compilation

[hellomissingdata]

I deleted the duplicates. Thanks! Jing

[bgoodri]

In RStudio, execute file.edit("~/.R/Makevars")

Thanks!! It prints this:

CC=clang
CXX=clang++

CXXFLAGS=-O3 -Wno-unused-variable -Wno-unused-function

CXXFLAGS=-O3 -Wno-unused-variable -Wno-unused-function

CC=clang
CXX=clang++ -arch x86_64 -ftemplate-depth-256

So I just delete the duplicate line in the middle?

[bgoodri]

And the first line probably
