Re^6: [OT] Installing g++ compiler on ubuntu-12.04LTSby syphilis (Canon)

It seems possible some people have 64 bit Perl builds, and only a 32-bit libstdc++
AFAICT, if that test script builds ok, then you know a suitable libstdc++ for the chosen g++ compiler has been found.
Once it is established that libstdc++ has been found, *then* you do the test to determine whether iostream is present.
As you know, just because there's a suitable libstdc++ for the chosen compiler doesn't necessarily mean that's the right g++ compiler for that build of perl.
But knowing that there's at least a libstdc++ for the compiler that was chosen might help narrow things down for you.
Still trying to find something that tells me how to run g++ in 64-bit mode on my deb box :-(
