[ruby-core:120314] [Ruby master Bug#20967] Oracle Developer Studio 12.5 on Solaris 10 miniruby symbol referencing error: Undefined symbol: atomic_signal_fence

["ngoto (Naohisa Goto) via ruby-core" <ruby-core@ml.ruby-lang.org>]

Issue #20967 has been updated by ngoto (Naohisa Goto).

Status changed from Open to Closed

I think that it is difficult to add `-xatomic=studio` or `-xatomic=gcc` automatically to `cflags` or `CFLAGS` by `./configure` because it is difficult to determine which is appropriate or better option.
I think installing users should determine this.
Generally, I think `-xatomic=gcc` is preferred on system with GCC installed.

So, closing this issue.

----------------------------------------
When compiling Ruby 3.3 or head by using Oracle Developer Studio 12.5 on Solaris 10, failed to make miniruby with the following error messages:

```
Undefined                       first referenced
 symbol                             in file
atomic_signal_fence                 vm.o
ld: fatal: symbol referencing errors. No output written to miniruby
make: *** [miniruby] Error 2
```

Ruby 3.3.4 or later may be affected.

This error occurred because of improper selection of atomic library in Oracle Developer Studio.
https://docs.oracle.com/cd/E77782_01/html/E77789/gqhbq.html

Adding `cflags` to `-xatomic=studio` or `-xatomic=gcc` when running `./configure` solved the problem.

For example,
```
./configure --prefix=/opt/ruby340 cflags="-xatomic=gcc"
```
