make all fails because: error: request for member 'val' in something not a structure or union

[mikey-]

Hi ^___^

Firstly, here is what I'm working with:

mikey@some-server:~/linux$ lsb_release -a
No LSB modules are available.
Distributor ID:  Ubuntu
Description:     Ubuntu 12.04.5 LTS
Release:         12.04
Codename:        precise

mikey@some-server:~/linux$ uname -a
Linux some-sever 3.2.0-69-virtual #103-Ubuntu SMP Tue Sep 2 05:21:29 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

--------------------The Problem------------------- I'm trying to run make all and I received the exact same error that was reported in #91

I followed the advice ("comment out the offending lines. They aren't used") It made the problem go away for ctl.c (though note the warning about uid in the output below) but I'm now seeing a lot more errors. Not really sure what to do at this point. Any help would be super mad ^_^

Here is the output from make all:

try modifying dtrace_linux.h to use the other branch of the #if where the Kxxx_VALUE macros are defined.

I'll give it a go :sparkles::sparkling_heart::sparkles: thanks

okay so here's the change I made:

After that I was able to make all. I did get the following warning though:

build/ctfconvert not available - so not building the linux.ctf file
NOTE: The build is complete, but build/ctfconvert is not available.
      This means you will get run time errors from the io.d and sched.d files
      due to undefined kernel structure definitions. Simply delete or rename
      these files until a fix can be put in place to handle older
      distros which do not have the required libdwarf dependencies.

      (Typical error is references to undefined struct definitions such
      as dtrace_cpu_t).

I'll let you know how it goes...

I gave up on trying to make it work with 12.04 I upgraded what I was working on to 14.04 and I had no problems doing make all, make install, make load

Thanks for all your help.

[phamtranquocviet]

I am trying to install dtrace for the first time too and got the same error. What is 12.04?

[mikey-]

Dunno if you worked it out but 12.04 was the version of Ubuntu I was working with
