Webb Phillips commented on ARROW-12802: --------------------------------------- Oops you're right. WIth further testing, I find that: • R apache-arrow-3.0.0 builds and works on Ubuntu 18.04, R 4.0.3, devtools: {code:java} install_github('apache/arrow',subdir='r',ref='apache-arrow-3.0.0',clean=T,force=T) {code} • R apache-arrow-4.0.0 and current HEAD builds but crashes on use on Ubuntu 18.04: {code:java} Error in io___MemoryMappedFile__Open(path, mode) : Cannot call io___MemoryMappedFile__Open(). See https://arrow.apache.org/docs/r/articles/install.html for help installing Arrow C++ libraries.{code} • R apache-arrow-1.0.1 builds and works on macOS 10.13.6, R 4.0.4, devtools: {code:java} install_github('apache/arrow',subdir='r',ref='apache-arrow-1.0.1',clean=T,force=T){code} • R HEAD, apache-arrow-4.0.0, 3.0.0 (and probably 2.0.0) don't build on macOS 10.13.6, R 4.0.4, devtools because of ARROW_CSV=OFF • If I build and install libarrow apache-arrow-4.0.0 with ARROW_CSV=ON first, then R apache-arrow-4.0.0 builds and works (because it uses already installed libarrow) on macOS 10.13.6, R 4.0.4, devtools By hypothesis, I could also skip libarrow and manually build only R arrow with ARROW_CSV=ON. > No more default ARROW_CSV=ON in libarrow build breaks R arrow > ------------------------------------------------------------- > > Key: ARROW-12802 > URL: https://issues.apache.org/jira/browse/ARROW-12802 > Project: Apache Arrow > Issue Type: Bug > Affects Versions: 4.0.0, 4.0.1 > Reporter: Webb Phillips > Priority: Major > > libarrow build succeeds, but include/arrow/csv/type_fwd.h isn't installed > since 4.0.0.
