Subject: [ruby-core:111093] [Ruby master Bug#19161] Cannot compile 3.0.5 or 3.1.3 on Red Hat Enterprise Linux 7

Issue #19161 has been updated by werebus (Matt Moretti).





Thanks everyone,



I can confirm that adding `cflags="-std=gnu99"` to the configure step worked around my issue. Re-running `./autogen.sh` on the server in question also worked.

Bug #19161: Cannot compile 3.0.5 or 3.1.3 on Red Hat Enterprise Linux 7

https://bugs.ruby-lang.org/issues/19161#change-100358



* Author: werebus (Matt Moretti)

* Status: Closed

* Priority: Normal

* Backport: 2.7: DONTNEED, 3.0: REQUIRED, 3.1: REQUIRED

----------------------------------------

When attempting to run `make` on either the 3.0.5 or 3.1.3 release, I get the following error (I included the whole output as it's pretty short):

```



Both Ruby 3.0.4 and 3.1.2 build without error and pass (all but one of) the `make check` tests.



I know RHEL 7 is getting to be pretty old; I suspect a factor here are the ancient build tools available to me. But... EOL for Ruby 2.7 comes before the one for RHEL 7, so I'm trying to prioritize.
