[Valgrind-users] Analyzing 32bit applications on X86_64 - no more supported?

[Avi G. <av...@ch...>]

Hi,

In the past it was possible to analyze 32bit applications on 64bit OS as mentioned in this post: http://sourceforge.net/p/valgrind/mailman/message/23606386/

I have a similar situation, thus I crossed compiled Valgrind to run it on a X86_64 target. It analyzes 64bit applications very well. However, when trying to analyze 32bit applications I get:
valgrind: failed to start tool 'memcheck' for platform 'x86-linux': No such file or directory

It appears that memcheck-x86-linux is not generated when cross compiling Valgrind 3.9.0 for X86_64.

I tried to work around this by copying the relevant tools from i386 compilation to /usr/lib. Valgrind run but failed to find most of memory errors.

Is there a way to analyze 32bit applications on X86_64 using Valgrind?

Thanks,
Avi

Still is.

Then it appears that it probably didn't find the 32 bit toolchain when 
you built it - check the output of configure to see what it says.

It appears that the x86_64 cross compiler does not support 32bit:
checking for 32 bit build support... no

I'll try to figure this out.
Thanks for your help,
Avi
