OK. I figured it out. Apparently the compiler expects a specific version for libcstdc++ to be supported. When I downloaded the g++ aarch64 C++ cross compiler I picked g++-13-aarch64-linux-gnu package as it was flagged as the recommended package in the Ubuntu repositiry according to the Synaptic Package Manager. Apparently, package 13 wants a libstdc++ to be VERSION 32. But Raspberry Pi only distributes a libstdc++ of max version 30 supported.
So, I looked at the Synaptic Package manager and there is a g++-12-aarch64-linux-gnu package available. So, I loaded the g++-12-aarch64-linux-gnu package. It loaded a bunch of other support packages, cpp-12, gcc-12, etc. I was worried it would copy over the aarch64-linux-gnu-g++ but it didn't. It was smart enough to avoid package crashing. I checked using
Note that it added a"-12" in appropriate places to allow packages 12 and 13 to exist simultaneously.
So, then I did a build using the "-12" version
Then on the target machine (hostname sws.local) I ran the b.out executable (the one I cross compiled on the build host)
So, for user level applications I want to cross compile I need to use the "-12" versions of the commands. I'll probably keep using the "-13" version for the kernel since that seems to be working fine.
I guess it makes sense that it worked when compiling it on the RPI Zero 2 w. On the target the g++ compiler is version 12.
The "-12" version of the cross compiler is also version 12
Thanks
