Re: [PerfSuite-users] perfsuite on x86_64

[Rick K. <rk...@nc...>]

Steve,

Coincidentally, another user reported this to the perfsuite-users mailing 
list on SourceForge, so I will answer and hopefully move towards solving 
two problems at once...

This error is similar to one that has occurred on IA-64 machines where 
32-bit libraries are mixed with 64-bit.  It comes into play when the BFD 
extension that is used by psprocess is being built (libbfd.a).  I had 
difficulty resolving this on an x86-64 machine as well, and as I recall 
the solution I ended up using was to avoid attempting to build that 
particular extension for PerfSuite.  This is done by adding 
--disable-binutils to the configure command line, and rebuilding the 
package.  It wouldn't hurt to do "make distclean" first, to get everything 
back to its original state.

There should be no loss of functionality when configured with 
--disable-binutils, but what will happen is that PC->source line mapping 
will be done by an external "addr2line" process rather than purely through 
psprocess/Tcl.

It may also help to explicitly request the "bitness" of the build, which I 
believe is done through the gcc option "-m32" or "-m64", depending on 
which you want.  This is also done at configure time, through the CFLAGS 
variable, e.g.:

    ./configure [options] CFLAGS="-m32 <others>"
