I checked my Ubuntu Mate 64-bit using Synaptic Package Manager. I saw I have binutils-common:i386 and binutils-i686-linux-gnu installed. Those packages are provided by Ubuntu because we can see the icon on the right of the names.
I tried to install
binutils:i386. But, while doing this, the system tried to uninstall the
64-bit version of binutils and eventually the
64-bit gcc environment, up to the point that
ubuntu-desktop was no longer working. I had to reinstall them back, which forced a removal of 32-bit binutils. So, it seems to me, that
it is not possible to install 32-bit Lazarus on a 64-bit Linux. (This was not the case with Windows though, were I could install 32-bit Lazarus on a 64-bit Windows.)
You need to install multi-arch if you want to run 32 bit on 64 bit linux,
I will try to go this path. Some pointers will be highly appreciated.
Thanks.
