Issue #20151 has been updated by shyouhei (Shyouhei Urabe). This has to be related: https://github.com/freebsd/freebsd-src/commit/af3c78886fd8d4ca5eebdbe581a459... Because `ruby_qsort` is now a macro that ultimately expands to a `_Generic`, which is an expression, which cannot exist at the toplevel. We already have a sane `qsort_r` implementation in that environment. We don't have to reinvent the wheel. I guess reaching at util.c:255 is already something wrong. ---------------------------------------- Bug #20151: Can't build Ruby 3.1 on FreeBSD 14.0 https://bugs.ruby-lang.org/issues/20151#change-106097 * Author: hsbt (Hiroshi SHIBATA) * Status: Open * Priority: Normal * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN ---------------------------------------- I couldn't install Ruby 3.1.3 on FreeBSD 14.0. ``` compiling util.c util.c:255:1: error: expected identifier or '(' ruby_qsort(void* base, const size_t nel, const size_t size, cmpfunc_t *cmp, void *d) ^ ./include/ruby/util.h:124:21: note: expanded from macro 'ruby_qsort' # define ruby_qsort qsort_r ^ /usr/include/stdlib.h:356:5: note: expanded from macro 'qsort_r' __generic(arg5, int (*)(void *, const void *, const void *), \ ^ /usr/include/sys/cdefs.h:322:2: note: expanded from macro '__generic' _Generic(expr, t: yes, default: no) ^ 1 error generated. *** Error code 1 Stop. ``` Compiler version is here: ``` FreeBSD clang version 16.0.6 (https://github.com/llvm/llvm-project.git llvmorg-16.0.6-0-g7cbf1a259152) ``` I could install Ruby 3.2.2. -- https://bugs.ruby-lang.org/
