I am using Ubuntu 25.10 running in a WSL2 box on win 10.
Didn't realize I needed to rebuild after installing 32bit runtime. All is looking much better. Except now I have to debug our tool running on 32 bits. 😊 Thanks, Mark -----Original Message----- From: Paul Floyd via Valgrind-users <[email protected]> Sent: Friday, January 16, 2026 12:55 PM To: [email protected] Subject: Re: [Valgrind-users] set up Valgrind for multiple targets On 2026-01-16 21:05, Mark Roberts wrote: > I'd like to be able to use Valgrind on both x86 and x86-64 binaries > running on my x64-64 linux system.

At the moment I mainly use FreeBSD amd64, Fedora Linux amd64 and a bit of openSUSE amd64. For systems where I have the full 32bit subsystem installed then all I have to do is run configure. Autoconf should detect both amd64 and x86 and build both of them. So really all that you need to to is to install the x86 libc. You need the x86 C++ standard lib if you want to run the regression tests. openSUSE has removed the x86 startup file from gcc so it can no longer build x86 binaries (it will still run them). So in some cases you may need to build a compiler for the platform.
