compilation problem

[Jun Koi]

Hi,

I am trying to compile systemtap 0.7. To do so, I first try to compile
and install elfutils-0.131 (latest version?). However, this failed!
Here is how I did:

- Get elfutils-0.131.tar.gz and elfutils-portability.patch from
http://sourceware.mirrors.tds.net/pub/sourceware.org/systemtap/elfutils/
- Patch elfutils-0.131 with elfutils-portability.patch (Is this really
necessary? If so, why it is separated?)
- Run ./configure, then make inside elfutils-0.131/.

This results in error like below:

..........

My machine is x86, compiler gcc 4.2.3 on Ubuntu 8.04

How can I fix this?

Many thanks,

The latest version of elfutils can be found at
https://fedorahosted.org/elfutils/ and is 0.135.

I don't really remember. I believe the portability.patch isn't needed
anymore with newer elfutils. If a newer elfutils build works for you
without needing the patch then please let us know.

This sounds like the problem reported here:

I revised the README file to point out elfutils' new home.  But are
you sure you need a custom build of elfutils at all?  On my ubuntu 8
box, the system elfutils is sufficient; have you tried follow the
"SystemtanOnUbuntu" wiki page?

Because I want to play with the source code of Systemtap.

Thanks,

Thanks, that works perfectly! So the portability patch seems not necessarily.

I compiled 0.135 with the below command:

./configure CFLAGS=-fgnu89-inline
make

So, how about having the -fgnu89-inline default option??

Many thanks,
Jun

Thanks for checking!

I don't really know how inline works across different gcc versions or
across distro versions. I see that various distributions patch elfutils
to contain something like:

#if defined(__GNUC_GNU_INLINE__) || defined(__GNUC_STDC_INLINE__)
#define inline inline __attribute__ ((gnu_inline))
#endif

Maybe that can be pushed upstream if it is the correct behavior that is
needed by elfutils.
