If we build perf with NO_LIBPYTHON=1 NO_LIBPERL=1 the '-ldl'
is not added to libs build fails if we have gtk2 code in,
because it depends on it.

We fail build with NO_DEMANGLE with missing -lbfd externals error.
The reason is that we now use bfd code in srcline object:
  perf tools: Implement addr2line directly using libbfd

So we need to check/add -lbfd always now.

We're missing ifdef LIBAUDIT_SUPPORT condition check
for calling cmd_trace, otherwise the NO_LIBAUDIT=1
build fails.

Introduced by commit:
  perf trace: Add 'trace' alias to 'perf trace'

When building minimal perf via:
  NO_LIBPERL=1 NO_LIBPYTHON=1 NO_NEWT=1 NO_GTK2=1 NO_DEMANGLE=1
  NO_LIBELF=1 NO_LIBUNWIND=1 NO_BACKTRACE=1 NO_LIBNUMA=1 NO_LIBAUDIT=1
  NO_LIBBIONIC=1

We dont link -ldl and that's causing error for gtk2 related code,
which is disabled on command line (NO_GTK2), but not in the code
(GTK2_SUPPORT).

We probably need some global fix/change for this browser
enabled/disable code.

Tested just by building it corretly.

But for now what you did is enough, since the only module that uses
the dl mechanism is the GTK+ one, so I'm applying it.

I should have detected this before pushing out perf/core with the
changes that introduced this problem, that is what:

  make -C tools/perf -f tests/make

was made to catch, my bad, Namhyung, please use those tests next time
too :-)

> Tested just by building it corretly.

Yeah, now tests/make completes without problems.

Thanks,

Is it enough to check on -lbfd only?  I guess libbfd can have additional
dependencies to libiberty and libz.  If so, this patch can fail to set
-DLIBBFD_SUPPORT, right?

Thanks,
Namhyung

hum, you're right.. so it's 2 bugs fixed by removing that code ;-)

I tested this on my system.  At first I guessed (without testing) it
cannot build SOURCE_BFD with -lbfd only due to additional -liberty and
-lz dependency, but it's not.  Actually the libfd.so is a plain text
file which contains linker script like this:

  $ file /lib64/libbfd.so
  /lib64/libbfd.so: ASCII text

  $ cat /lib64/libbfd.so
  /* GNU ld script */
  
  /* Ensure this .so library will not be used by a link for a different format
     on a multi-architecture system.  */
  OUTPUT_FORMAT(elf64-x86-64)
  
  /* The libz dependency is unexpected by legacy build scripts.  */
  INPUT ( /usr/lib64/libbfd.a -liberty -lz )


So it should handle external dependencies.  But it doesn't.

  $ cat bfd.c
  #include <bfd.h>
  
  int main(void)
  {
  	bfd_demangle(0, 0, 0);
  	return 0;
  }

  namhyung@sejong:tmp$ gcc bfd.c -lbfd
  /usr/lib64/libbfd.a(plugin.o): In function `try_load_plugin':
  (.text+0x1ab): undefined reference to `dlopen'
  /usr/lib64/libbfd.a(plugin.o): In function `try_load_plugin':
  (.text+0x1ca): undefined reference to `dlsym'
  /usr/lib64/libbfd.a(plugin.o): In function `try_load_plugin':
  (.text+0x263): undefined reference to `dlerror'
  collect2: error: ld returned 1 exit status


It seems that it needs libdl for loading plugins.  Adding -ldl makes
above build successfully.  So we need to add -ldl for EXTLIBS IMHO.
Without it, make NO_GTK2=1 NO_LIBPERL=1 NO_LIBPYTHON=1 will fail to
check libbfd correctly (FYI, libperl and libpython add -ldl to the
dependency list).

Thanks,
Namhyung

hum, so on my system -liberty check wins without -lbfd,
so 'NO_GTK2=1 NO_LIBPERL=1 NO_LIBPYTHON=1' passes

I need to check Ingo's latest changes on this, not sure how
if this problem is relevant any longer ;-)

AFAICS, Ingo's patch does "-lbfd -ldl" rather than "-lbfd".  So probably
there's no problem then. :)

I didn't fully demangle the maze of demangler feature tests yet :-) I 
added a single testcase, the rest is still detected using the old method.

Any assymetry in detection is probably a bug in my patches.

If that nested series of conditions is really necessary then we can add 
separate testcases for each, the same file built with different linker 
flags.

Thanks,

	Ingo

perf tools: Add missing -ldl for gtk build

If we build perf with NO_LIBPYTHON=1 NO_LIBPERL=1 the '-ldl' is not
added to libs build fails if we have gtk2 code in, because it depends on
it.
