Issue #15726 has been updated by robin850 (Robin Dupret).


Okay, I'm sorry for the noise here. Actually this was a setup problem.

As for the strange file names, this was due to the fact that I was using Fish as the \
shell to compile Ruby ; switching to Bash fixed the problem.

As for the `ar` command being killed, this was due to the overcommit settings. \
Switching `overcommit_memory` to 1 fixed the problem.

Sorry again.

Bug #15726: Error compiling Ruby

----------------------------------------
Hello,

I'm sorry if I'm reporting that to the wrong place but the errors are so meaningless \
that it's hard to know where the issue really comes from.

Trying to install Ruby by compiling it, several errors happen. The process follows \
these commands:


``` shell
$ wget https://cache.ruby-lang.org/pub/ruby/2.6/ruby-2.6.2.tar.gz
$ tar -xvf ruby-2.6.2.tar.gz
$ cd ruby-2.6.2
$ ./configure
$ make V=1
```

Actually the `make` task fails. The first time, it fails at the `ar` step:

```
Makefile:283: recipe for target 'libruby-static.a' failed
make: *** [libruby-static.a] Interrupt
```

Running `make` in verbose mode show that the error happens running:

```
ar rcD  libruby-static.a dln.o localeinit.o loadpath.o array.o ast.o bignum.o class.o \
compar.o compile.o complex.o cont.o debug.o debug_counter.o dir.o dln_find.o \
encoding.o enum.o enumerator.o error.o eval.o file.ogc.o hash.o inits.o io.o iseq.o \
load.o marshal.o math.o mjit.o mjit_compile.o node.o numeric.o object.o pack.o \
parse.o proc.o process.o random.o range.o rational.o re.o regcomp.o regenc.o \
regerror.o regexec.o regparse.o regsyntax.o ruby.o safe.o signal.o sprintf.o st.o \
strftime.o string.o struct.o symbol.o thread.o time.otranscode.o transient_heap.o \
util.o variable.o version.o vm.o vm_backtrace.o vm_dump.o vm_trace.o \
coroutine/amd64/Context.o  enc/ascii.o enc/us_ascii.o enc/unicode.o enc/utf_8.o \
enc/trans/newline.o explicit_bzero.o setproctitle.o strlcat.o strlcpy.o addr2line.o  \
prelude.o dmyext.o dmyenc.o ```

Running it manually says :

```
ar: file.ogc.o: No such file or directory
```

And ditto for `time.otranscode.o` once `file.ogc.o` has been replaced with `file.o`. \
Replacing `time.otranscode.o` with `time.o` makes the error go away but running the \
command for a few seconds, then it exits with `Killed` but nothing is present in \
`dmesg`.

Trying to rerun `make`, the standard library gets compiled but it fails trying to \
compile BigDecimal with the following error:

Is that a bug in the compilation process or something I do wrong or missing in my \
setup ?

System configuration:

* System: Debian 9.8 Stretch (Linux Kernel 2.6.32)
* GCC: 6.3.0 20170516
* Make: 4.1
* ld: GNU ld (GNU Binutils for Debian) 2.28
* OpenSSL : 1.1.0j  20 Nov 2018
* Yacc: Bison 3.0.4

Thanks for your time !
