[oi-dev] ruby 3.1.0preview1

[stes@PANDORA.BE]

Hello,

I tried compiling ruby 3.1 preview on OpenIndiana (Illumos) and this works:

./configure --prefix=$HOME/ruby-31 --with-gcc --disable-dtrace
gmake
gmake install

It works:

$HOME/ruby-31/bin/ruby --version
ruby 3.1.0preview1 (2021-11-09 master 5a3b2e6141) [i386-solaris2.11]

It succesfully compiles with the above config line and seems to work.

You can see in the above that it builds a 32bit by default, I did not yet try a full 64bit compile.

Note that I use the --with-gcc to select the OpenIndiana GCC compiler (not OpenIndiana clang).

Also for some reason it seems I have to use --disable-dtrace.

In older versions < 3.0 this works with DTRACE enabled, but this is apparently broken since 3.0.x

If I compile with dtrace enabled I get:

checking whether dtrace USDT is available... yes(-xnolibs)
checking whether dtrace needs post processing... rebuild


and then during compile

Does anyone know what ruby-glommed is and what exactly broke here ?

It seems some sort of rebuild code generation is done in the dtrace case ,
but I am not familiar with the ruby config/build system to see what exactly.

I've asked the Ruby list what the error with gar (GNU ar) is precisely,
but chances are they are not so familiar either with DTRACE.

There exist similar reports for FreeBSD like

https://bugs.ruby-lang.org/projects/ruby-master/repository/git/revisions/95aff214687a5e12c3eb57d056665741e734c188

"The latest ruby cannot compile with FreeBSD Dtrace enabled."

I'll log a ruby issue about this for OpenIndiana as well.

Thanks,
