Date: 2018-11-10T11:28:43+00:00 Subject: [ruby-dev:50667] [Ruby trunk Bug#15292] Since r64852, on Solaris with Oracle Developer Studio 12.6, compile error of iseq.c Issue #15292 has been updated by ngoto (Naohisa Goto). iseq.c のコンパイルは通りましたが、謎のリンクエラーが発生していました。 コンパイラまたは周辺のバグかもしれませんが全く不明です。 ~~~ cc -errtags=yes -xO4 -xtarget=sparc64xplus -m64 -L. -L/usr/local/64/lib -R/usr/local/64/lib main.o dmydln.o miniinit.o dmyext.o miniprelude.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.o gc.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.o transcode.o transient_heap.o util.o variable.o version.o vm.o vm_backtrace.o vm_dump.o vm_trace.o probes.o enc/ascii.o enc/us_ascii.o enc/unicode.o enc/utf_8.o enc/trans/newline.o sparc.o explicit_bzero.o flock.o isinf.o setproctitle.o addr2line.o -lpthread -lrt -lrt -lrt -lgmp -lsocket -ldl -lcrypt -lm -lm -o miniruby Undefined first referenced symbol in file .L10394 iseq.o .L10395 iseq.o .L10396 iseq.o .L10397 iseq.o .L10398 iseq.o .L10399 iseq.o .L10400 iseq.o .L10401 iseq.o .L10402 iseq.o .L10403 iseq.o ld: fatal: symbol referencing errors.
