From: "shyouhei (Shyouhei Urabe)" Date: 2022-04-14T07:39:50+00:00 Subject: [ruby-core:108230] [Ruby master Misc#18726] CI Error on c99 and c2x Issue #18726 has been updated by shyouhei (Shyouhei Urabe). The problem is whether we are allowed to do this. ```patch From b60e5fdfa540a0ddef35f5dc904d004d226dac25 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?=E5=8D=9C=E9=83=A8=E6=98=8C=E5=B9=B3?= Date: Thu, 14 Apr 2022 16:34:22 +0900 Subject: [PATCH] require autoconf 2.70 Fixes [Misc #18726] See also https://lists.gnu.org/r/autoconf-patches/2020-08/msg00000.html --- configure.ac | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/configure.ac b/configure.ac index cbc53231d8..9f5ae83254 100644 --- a/configure.ac +++ b/configure.ac @@ -3,7 +3,7 @@ AC_INIT { AC_CONFIG_AUX_DIR(tool) -AC_PREREQ(2.67) +AC_PREREQ(2.70) tooldir="$srcdir/tool" -- 2.17.1 ``` ---------------------------------------- Misc #18726: CI Error on c99 and c2x https://bugs.ruby-lang.org/issues/18726#change-97251 * Author: znz (Kazuhiro NISHIYAMA) * Status: Open * Priority: Normal * Assignee: shyouhei (Shyouhei Urabe) ---------------------------------------- https://github.com/ruby/ruby/runs/6013849896?check_suite_focus=true ``` checking char bit... 8 checking size of int... 0 checking size of short... 0 checking size of long... 0 configure: error: in `/__w/ruby/ruby/build': configure: error: cannot compute sizeof (long long) See `config.log' for more details checking size of long long... Error: Process completed with exit code 77. ``` I investigate it, the cause is that autoconf is old in `ghcr.io/ruby/ruby-ci-image:clang-15`. (Autoconf 2.69) Autoconf 2.71 generates with `void`. How to reproduce: ``` % docker run --rm -it ghcr.io/ruby/ruby-ci-image:clang-15 $ sudo apt update $ sudo apt install git $ git clone --depth=1 https://github.com/ruby/ruby $HOME/src $ mkdir $HOME/build $ cd $HOME/build $ ../src/autogen.sh $ ../src/configure -C --enable-debug-env --disable-install-doc --with-ext=-test-/cxxanyargs,+ --without-valgrind --without-jemalloc --without-gmp --with-gcc="clang-15 -std=c99 -Werror=pedantic -pedantic-errors" --enable-shared optflags=-O1 debugflags=-ggdb3 ``` Tail of configure output: ``` checking char bit... 8 checking size of int... 0 checking size of short... 0 checking size of long... 0 checking size of long long... configure: error: in `/home/ci/build': configure: error: cannot compute sizeof (long long) See `config.log' for more details ``` Quote from config.log: ``` configure:13939: checking size of int configure:13944: clang-15 -std=c99 -Werror=pedantic -pedantic-errors -o conftest -O1 -fno-fast-math -ggdb3 -fdeclspec -fstack-protector-strong conftest.c -lm >&5 conftest.c:107:25: error: a function declaration without a prototype is deprecated in all versions of C [-Werror,-Wstrict-prototypes] static long int longval () { return (long int) (sizeof (int)); } ^ void conftest.c:108:35: error: a function declaration without a prototype is deprecated in all versions of C [-Werror,-Wstrict-prototypes] static unsigned long int ulongval () { return (long int) (sizeof (int)); } ^ void 2 errors generated. ``` -- https://bugs.ruby-lang.org/ Unsubscribe:
