changed distributions, kernel not working..

jdhar,

Even in the 64-bit port of Quartus II on Linux, a fair amount of the tool runs in 32-bit mode. You can easily determine which binaries are 32-bit and which are 64-bit by performing a 'file' command on them.

Now, directly to your question....most, if not all, of the toolchain is 32-bit code. It does successfully run on 64-bit architectures through a 32-bit "emulation" layer.

I'm using an amd64 version of Gentoo Linux with no issues.

I would suspect that you have some sort of installation or environment issue causing your problem.

Cheers,
