How to run Valgrind/Helgrind on 32bit apps, in 64bit OS

[b_dutta]

Hi,

I have a x86_64 arch system, running RHEL4.6 x86_64. However, the application
I would like to use Valgrind on, is a 32-bit application (due to some legacy
library dependencies, which are available 32-bit only).

Should I be using the Valgrind v3.5.0 x86_64 version, or the i386 version (x86)
in this environment ? Also, I believe, installation of the x86 version might
meet with lot of unfulfilled dependencies (glibc specific version, x86 flavour
etc.)!

Any known best-practices for the above scenario ?

Thanks,
BDutta

Use the x86_64 version.  It builds two versions of Valgrind, one that
handles 64-bit programs and one that handles 32-bit programs, and it
will transparently choose the appropriate one.  In other words, It
Should Just Work.

So, if I install the x86_64 version package (.rpm, .deb etc., on my favourite
Linux distro), it should work out of the box ? Or, do I need to build the
package on the target platform, from source ?

Also, is the same true for the tool, Helgrind ? Does the Helgrind tool, part of
the Valgrind x86_64 package, work for both 32bit & 64bit applications ? Asking
because --
when we tried to run Helgrind on RHEL 5.3 (Valgrind - 3.2.1-6.e15 ), it says
Helgrind not supported and says use Valgrind - 2.4 for Helgrind support !!

Thanks for the response.

The packaged version should be fine. Assuming of course that it is an
appropriate version for what you want.

It is true of all tools, yes.

That's because helgrind was not supported on any platform in that
version of valgrind - it is supported again in newer versions.

I have the same problem building Valgrind 3.5.0 on Debian. However, it
seems to be a gcc-4.{3,4} issue. This is the result of the configure
test when trying to build a 32 bit code:

configure:4326: checking for 32 bit build support
configure:4349: gcc -o conftest -m32   conftest.c  >&5
/usr/bin/ld: skipping
incompatible /usr/lib/gcc/x86_64-linux-gnu/4.3.4/libgcc.a when searching
for -lgcc
/usr/bin/ld: skipping
incompatible /usr/lib/gcc/x86_64-linux-gnu/4.3.4/libgcc.a when searching
for -lgcc
/usr/bin/ld: cannot find -lgcc
collect2: ld returned 1 exit status

Well the simple answer is that you haven't got a 32 bit libgcc installed.

I think you probably want to install lib32gcc1 on Debian, but that's a
bit of a guess and I'm not sure if that is a development package or just
a runtime.
