When I run my script with Ruby 2.5, I get the following output from irb: ~~~ ruby puts RbConfig::CONFIG['LIBS'] # -lpthread -ljemalloc -ldl -lcrypt -lm ~~~ However, if I build Ruby 2.6 in the exact same way, I do not see -ljemalloc flag: ~~~ ruby puts RbConfig::CONFIG['LIBS'] # -lm ~~~ I've attached the output from the configure and make steps to this. Did something change? Or do I need to change the way I do jemalloc detection with Ruby 2.6? ---Files-------------------------------- 2-5.log (62.8 KB) 2-6.log (71.1 KB) rubyinstall.sh (1.97 KB) -- https://bugs.ruby-lang.org/ Unsubscribe:
