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:

$ 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 !

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.
