Issue #19353 has been updated by eightbitraptor (Matthew Valentine-House). I recently encountered a CI failure when testing against `C++98` due to the lack of variadic macros. `internal/gc.h` states that ``` * @note To ruby-core: remember that this header can be possibly * recursively included from extension libraries written in C++. * Do not expect for instance `__VA_ARGS__` is always available. * We assume C99 for ruby itself but we don't assume languages of * extension libraries. They could be written in C++98. ``` If we're assuming that Ruby itself targets `C99`, does this mean that dropping `GCC6` would allow us to relax the testing requirement for `C++98`? ---------------------------------------- Misc #19353: Drop gcc <= 6 and clang <= 9 https://bugs.ruby-lang.org/issues/19353#change-101331 * Author: shyouhei (Shyouhei Urabe) * Status: Open * Priority: Normal ---------------------------------------- We test those old compilers using Ubuntu bionic.

OpenBSD/sparc64 uses gcc 4.2.1 (last GPLv2 version) as the system compiler. The sparc64 backend for clang is not yet mature (last I checked), so this would make it so Ruby 3.3+ would be unlikely to be supported on OpenBSD/sparc64 (at least, until the clang sparc64 backend matures). I would like to keep support for gcc 4.2.1 if possible, but I certainly understand if support has to be dropped.

Since writing this, we've found out that we can compile Ruby 3.2 on OpenBSD/sparc64 using the system compiler (gcc 4.2.1), but compiling gems with C extensions fails with the system compiler and we have to use an ports compiler (gcc 8.x I think). This wasn't the case for Ruby 3.1. Considering this, I withdraw my objection to dropping gcc < 6 support, since we can switch to compiling Ruby itself with the ports compiler on OpenBSD/sparc64. ---------------------------------------- Misc #19353: Drop gcc <= 6 and clang <= 9 https://bugs.ruby-lang.org/issues/19353#change-101860 * Author: shyouhei (Shyouhei Urabe) * Status: Open * Priority: Normal ---------------------------------------- We test those old compilers using Ubuntu bionic.
