From: Tom M Date: 2008-11-11T06:22:36+09:00 Subject: ruby 1.9.1 without native threads? I downloaded ruby 1.9.1-preview1 and ran ./configure --enable- threads=no on both Leopard and an old RH box. According to the configure script, this is a valid option. However, when I try to run make, I get an error: gcc -O2 -g -Wall -Wno-parentheses -pipe -fno-common -I. -I.ext/ include/i386-darwin9.5.0 -I./include -I. -DRUBY_EXPORT - D_XOPEN_SOURCE -D_DARWIN_C_SOURCE -o dmyencoding.o -c dmyencoding.c make: *** No rule to make target `thread_.h', needed by `miniprelude.o'. Stop. Is this an actual bug in the build, or is the configure script simply wrong in saying that ruby 1.9 can build w/o pthread? Thanks, Tom Macklin
