Even if configure.in would check that posix_memalign is broken, there seems to be no other way to do aligned alloc for OpenBSD. One would need to edit gc.c to do something different for OpenBSD. ---------------------------------------- Bug #5901: OpenBSD "[FATAL] failed to allocate memory" https://bugs.ruby-lang.org/issues/5901 Author: George Koehler Status: Assigned Priority: Normal Assignee: Narihiro Nakamura Category: Target version: ruby -v: ruby 2.0.0dev (2012-01-16 trunk 34316) [x86_64-openbsd5.0] =begin Ruby trunk fails to build with OpenBSD. During the build, miniruby fails with message [FATAL] failed to allocate memory OpenBSD has a broken posix_memalign(). Ruby fails in gc.c, because posix_memalign() fails and aligned_malloc() returns NULL. OpenBSD's manual for posix_memalign (()) says: BUGS Only alignments up to the page size can be specified. Ruby wants alignment of 16 kilobytes, but my page size is only 4 kilobytes. I tried to edit gc.c. My first attempt (bad-fix-never-apply.diff) was good enough to build Ruby, but it did not always work, and some tests failed. So I reverted gc.c and tried again. My second attempt (smaller-heap-for-openbsd.diff) was much simpler. I changed the values of HEAP_ALIGN*, shrinking the heap size from 16 kilobytes to 4 kilobytes, which is not larger than my page size. More tests pass. The only failures in 'make test' are in bootstraptest/test_thread.rb. Those tests seem to create an infinite loop in Ruby, and I needed to kill -9 those processes. Some tests in 'make test-all' failed the same way, with the infinite loop. =end -- http://bugs.ruby-lang.org/
