new pahole packet structure

new pahole packet structure

[Hagen Paul Pfeifer]

First one! ;-)

I re-structured the packet layout, droped cmake support with a lightweight
./configure replacement and fix some new occurred compiler warnings.

Hello Arnaldo, I replaced the current build system with a more common
configure && make && make install tuple. I drooped the cmake dependencies
completely - now a hand-crafted configure script replace the functionality.
There are some tiny issues for further releases: e.g. check for a valid
elfutils package (version > elfutils-0.128), sqlite checks, etc.

The current version doesn't utilize any auto-helltools, but the fundamental
structure is prepared. So if there is a demand in the future: no problem! ;)

I doesn't touched any functionality - no code is altered (expect some compiler
warnings, due to additional compiler flags. But there are some additional
warnings!).

The whole tarball is a packed git archive (master branch). The last commit was
b4d6de9b6f6. You can pull (and merge) it therefore locally. ;)

Doesn't work in my workstation:

Fixed!

The fix isn't yet git commited - I want a clean history. So Arnaldo, check
the new structure and post some comment! ;-)

Next problem:

[acme@doppio pahole]$ ./configure
*** configure-ng ***
checking for compiler...  /usr/lib64/ccache/gcc
checking for rm... /bin/rm
checking for ar... /usr/bin/ar
checking for ranlib... /usr/bin/ranlib
checking for mkdir... /bin/mkdir
checking for install... /usr/bin/install
checking for alloca... yes
checking for posix_memalign support... yes
checking for libdw... no
 Configure doesn't found libdw. Libdw is an essential package
 for this package! If this library (or header files) are not
 installed in a common directory you can specify it via
 --libdir=/PATH/TO/LIBRARY and/or --inludedir=/PATH/TO/HEADER
 Tip: libdw is bundled with elfutils
 URL: ftp://sources.redhat.com/pub/systemtap/elfutils/
rmdir: /tmp/tmp.cGoUy28831: Directory not empty
[acme@doppio pahole]$

On a Fedora 8 system:

[acme@doppio pahole]$ rpm -ql elfutils-devel
/usr/include/dwarf.h
/usr/include/elfutils
/usr/include/elfutils/elf-knowledge.h
/usr/include/elfutils/libdw.h
/usr/include/elfutils/libdwfl.h
/usr/include/elfutils/libebl.h
/usr/lib64/libdw.so
/usr/lib64/libebl.a
[acme@doppio pahole]$ rpm -ql elfutils-libelf-devel
/usr/include/gelf.h
/usr/include/libelf.h

ldconfig can also live in /sbin/ and variants of that... make sure you check those.

Strange! This should only be happens if libwd.so isn't in the standard search
path!

The configure script probe for libdw via:

gcc -ldw -o /dev/null dwtest.c

gcc -print-search-dirs | grep /usr/lib64/ should[tm] match! I tested the
configure script on Debian and Arch linux - NULL problems there. Anyway: I
will install fedora and test it one more time.

99% in /sbin - but I will catch the other percent too! ;-)

The library is installed in a standard library path, we can therefore skip the
ldconfig call and instead output

@echo
@echo "Please run ldconfig"
@echo

It is often the preferred way by distribution to start ldconfig by them self.
So the @echo "You can now run ldconfig" is the better solution.
