Bug #13041: ruby 2.4 rc1 dtrace build fixes

• Status: Closed
• Assignee: -
• Target version: -
• Backport: 2.1: UNKNOWN, 2.2: UNKNOWN, 2.3: UNKNOWN

[swills (Steve Wills)]

In FreeBSD before 11.0, using dtrace -G or -h will not work in a jail or without dtrace kernel modules loaded unless the -xnolibs flag is passed as well. Since we build in jails, this is needed during our build, so we have this patch:

https://svnweb.freebsd.org/ports/head/lang/ruby22/files/patch-Makefile.in?revision=369732&view=markup

We have used it with ruby 2.2, and 2.3 for a long time. Please consider it or a similar change for Ruby 2.4

[swills (Steve Wills)]

Sorry, forgot the configure fix as well:

https://svnweb.freebsd.org/ports/head/lang/ruby20/files/patch-configure.in?view=markup&pathrev=369732

(first part only, rest is other fixes)

[vo.x (Vit Ondruch)]

The "-xnolibs" is not supported by SystemTap :/

$ dtrace -xnolibs
/usr/bin/dtrace invalid option -xnolibs
Usage /usr/bin/dtrace [--help] [-h | -G] [-C [-I<Path>]] -s File.d [-o <File>]

Not sure if Nobu's patch covers this ...

SystemTap is not DTrace.

SystemTap is not DTrace.

SystemTap is Linux equivalent of DTrace and provides the dtrace tool with the same purpose of DTrace one ...

I suspect the build failure is due to the fact that dtrace -G modifies the .o files to remove the dtrace symbols.

It may provide a program with the same name, but it is not equivalent. If it did, this fix wouldn't break it for you.

On Solaris 10, the origin of dtrace, it seems "-xnolibs" is not supported.
List of available options that can be specified with "-x" on Solaris: http://docs.oracle.com/cd/E19253-01/817-6223/chp-opt/index.html

According to my testing, the patch committed r57093 works just fine even when the "-xnolibs" is not supported. So thanks to Nobu.

Unfortunately, that page is a bit out of date. Here's one page which has examples with -xnolibs:

Tried everything I could, but still can't get things to link, on 11.0 or 12-CURRENT. If I'm doing something wrong, please let me know.

Looks like r57101 r57102 r57103 and r57104 fixed this. Thanks!
