Bug #19329
Updated by apteryx (Maxim C.) over 2 years ago
Hello, Ruby! When building/installing C extensions via `gem install`, log files produced during the build get installed to the `GEM_VENDOR` location. This is undesirable because these files are not functional and they contain non-reproducible information such as temporary compilation file names or similar. Would it be possible to *not* have any log file installed, or have an option to turn it off? Reproducer, using nokogiri as an example: ``` $ GEM_VENDOR=output gem install nokogiri-1.13.10.gem --verbose --local --ignore-dependencies --vendor --bindir output/bin ``` ``` $ find
