FreeBSD Build --with-dtrace fails

[No9]

Apologies if this is a known issue as I seem to recall from a nodeup that there was some significant changes for DTrace going into 0.12.

Anyway I hope this is useful

The same issue presents on node v0.11.14 on the same system.
But on the same system v0.10.35 compiles OK
(But has the post compilation problem highlighted here
https://gist.github.com/indutny/d3fee964995eea206fb3)

On a digital ocean droplet..
Full info on all the ENV config I did here:
http://venshare.com/2015/01/16/dtrace-with-iojs-on-freebsd-10-1-using-digital-ocean/

So the following:

> sudo ./configure --with-dtrace --dest-cpu=x64
> sudo gmake

Fails with

@indutny or @jbergstroem, maybe one of you can take a look?

[jbergstroem]

Pretty busy at the moment, but the issue at least seems to start from tools/genv8constants.py not generating a proper header; the output is essentially empty from this:

builder% tools/genv8constants.py foo.h /usr/home/jbergstroem/io.js/out/Release/obj.target/deps/v8/tools/gyp/libv8_base.a && cat foo.h 

/*
 * File automatically generated by genv8constants. Do not edit.
 *
 * The following offsets are dynamically from libv8_base.a.  See src/v8ustack.d
 * for details on how these values are used.
 */

#ifndef V8_CONSTANTS_H
#define V8_CONSTANTS_H



#endif /* V8_CONSTANTS_H */

[indutny]

Oh gosh, need to look into it.

[No9]

So @indutny @jbergstroem spent a little time on this tonight.

objdump -z -D /usr/home/freebsd/io.js/out/Release/obj.target/deps/v8/tools/gyp/libv8_base.a | grep frametype_EntryFrame
Returns nothing

But
objdump -z -D /usr/home/freebsd/node/out/Release/obj.target/deps/v8/tools/gyp/libv8_base.a | grep frametype_EntryFrame
In the node v.0.10.35 build returns
0000000000000000 <v8dbg_frametype_EntryFrame>:

So it would seem that the technique used to identify the V8_CONSTANTS in tools/genv8constants.py is not going to work with the current build output of
/usr/home/freebsd/io.js/out/Release/obj.target/deps/v8/tools/gyp/libv8_base.a

Could there be an option missing on the V8 build part that is preventing the inclusion of the v8dbg sym?
Or have they gone away completely in this version of V8?

[indutny]

Oddly, I got this:

clang++: error: no such file or directory: '/usr/home/indutny/io.js/out/Release/obj.target/iojs/src/node_dtrace_ustack.o'
clang++: error: no such file or directory: '/usr/home/indutny/io.js/out/Release/obj.target/iojs/src/node_dtrace_provider.o'
iojs.target.mk:198: recipe for target '/usr/home/indutny/io.js/out/Release/iojs' failed

When trying to build it... Will figure out details.

[indutny]

Should be fixed by https://codereview.chromium.org/894003003/, I guess.

[indutny]

And by partially reverting: 8a83eba

[No9]

@indutny Cheers Ill apply that and see where I get to.

Also can you verify that I will need to patch FreeBSD with
https://svnweb.freebsd.org/base/head/cddl/contrib/opensolaris/lib/lib0dtrace/common/drti.c?pathrev=276250&view=log&r1=276250&log_pagestart=0

Because of dtrace DOF node: .SUNW_dof section corrupt

As mentioned here https://gist.github.com/indutny/d3fee964995eea206fb3#comment-1373787

Thanks again for finding time to dive into these issues 👍

[indutny]

That svnweb link gives me 404... :(

[No9]

Hmmm yup broken for me too :(

This is the another view here.
https://svnweb.freebsd.org/base?view=revision&revision=276250

[indutny]

Yeah, this is the fix. Luckily, it does not require rebuilding kernel.

[No9]

So applyied the patches to
globals.h
objects.h
gen-postmortem-metadata.py
And common.gypi has the patch you mention
But still getting

clang++: error: no such file or directory: '/usr/home/freebsd/io.js/out/Release/obj.target/iojs/src/node_dtrace_ustack.o'
clang++: error: no such file or directory: '/usr/home/freebsd/io.js/out/Release/obj.target/iojs/src/node_dtrace_provider.o'
iojs.target.mk:198: recipe for target '/usr/home/freebsd/io.js/out/Release/iojs' failed
gmake[1]: *** [/usr/home/freebsd/io.js/out/Release/iojs] Error 1
gmake[1]: Leaving directory '/usr/home/freebsd/io.js/out'
Makefile:52: recipe for target 'iojs' failed
gmake: *** [iojs] Error 2

Have I missed something?

[indutny]

Looking...

[indutny]

@No9 see https://github.com/indutny/io.js/tree/fix/postmortem for progress. So far getting:
