[genie (Genie Sol)]

Dear team,

I'm trying to compile ruby 2.1.1 on Solaris Oracle Solaris 11.1 SPARC, with gcc version 4.5.2 (GCC).

I wonder that maybe you can help on the issue.

Here is the result of the configure :

It complains for the conftest.c

gmake: *** [.rbconfig.time] Abort (core dumped)

[genie (Genie Sol)]

Just to give an update.

After many different tries, the solutions for compiling ruby 2.1 is to use Sunstudio rather than gcc.

This has working well.

• Status changed from Open to Feedback

It might be due to GCC bug, because GCC 4.5.2 is too old. Could you please try latest GCC?

[ngoto (Naohisa Goto)]

Thank you very much!

In my experience, compiling ruby with --enable-dtrace (enabled by default on Solaris during configure) and relatively higher compiler optimization flags (-O2, -O3 or higher) fails with bus error or segmentation fault. I still cannot specify whether the error is caused by compiler's optimization bug or Ruby source code.

Could you please also try gcc with optflags="-O1 -fno-fast-math" ?

[nichogl (Geoff Nichols)]

Hello, are there any plans to fix this issue in Ruby 2.1.4?

[ngoto (Naohisa Goto)]

Hello, are there any plans to fix this issue in Ruby 2.1.4?

No, because no one can identify the cause of the problem, and no one have provided patches.

Could you please try the following three configure options?

% ./configure --disable-dtrace
% optflags="-O0" ./configure
% optflags="-O0" ./configure --disable-dtrace

In addition, please confirm all available OS patches provided by Oracle are correctly applied.

I was bothered by bugs in dtrace command bundled in Solaris 10. Most of these bugs have been fixed by Solaris OS patches. Without patches, compiling ruby with optimization may fail.

[nichogl (Geoff Nichols)]

The issue still exists using the suggested ./configure and optflags. Not sure if this is obvious from the thread, but a compile builds a miniruby, but a bus error results from execution of that compiled miniruby. The miniruby gives expected output to ./miniruby --version or ./miniruby --help, but produces the bus error when called without any arguments.

$ ./miniruby --version

It looks like building with the compile.c patch still produces a miniruby with the bus error. Here's the backtrace:

please try another patch (file 20141023-compile_data_alloc-word-align.patch in https://bugs.ruby-lang.org/issues/9681 )

Please try to add "-mcpu=v9" to gcc, e.g.

% ./configure CFLAGS="-mcpu=v9" CXXFLAGS="-mcpu=v9" LDFLAGS="-mcpu=v9"

I can reproduce the Bug Error on SPARC Solaris10 with /usr/sfw/bin/gcc (gcc 3.4.3, SUNWgcc package).

The reason why this only occurs with gcc is that gcc generates SPARC V7 code by default, and 8-byte aligned memory access for 8-byte word (long long) may be required.

On the other hand, Oracle Solaris Studio seems to generate code using instructions extended in SPARCV8PLUS that allows unaligned memory access.

• Status changed from Feedback to Closed
• % Done changed from 0 to 100

Applied in changeset r48288.

• compile.c (compile_data_alloc): add padding when strict alignment
  is required for memory access. Currently, the padding is enabled
  only when the CPU is 32-bit SPARC and the compiler is GCC.
  [Bug #9681] [ruby-core:61715]

• compile.c (STRICT_ALIGNMENT): defined if strict alignment is required

• compile.c (ALIGNMENT_SIZE, ALIGNMENT_SIZE_MASK, PADDING_SIZE_MAX):
  new macros for alignemnt word size, bit mask, max size of padding.

• compile.c (calc_padding): new function to calculate padding size.
