[OpenIndiana-discuss] When this misery end?

[Hung Nguyen Gia]

Illumos is not 64 bit ready. This is why the compiler has to target 32 bit by default. All Illumos distros have this limitation.

Don't get me wrong, I have read that many parts of the OS itself remain to be 32 bit, e.g: nscd, they are not yet 64 bit ready.

I pretty much agreed and appreciate the Unleashed OS initiative but sadly it was terminated: https://unleashed-os.org/

It is, IMHO, what Illumos should be.

But you are partially right, though. Nothing stop we from setup the compiler to provide 64 bit binaries by default but still keeps the -m32 target so we could build the not 64 bit ready parts of the OS, too. This, indeed, is what many Linux distros are doing now. We are really weirded, because we are a 64 bit OS but choose to 'cross compile' to 32 bit by default. It should be the otherwise around: a 64 bit OS which generates 64 bit binaries by default but offer to 'cross compile' to 32 bit. But all of the Illumos distros did so, not only us. It's the general limitation of the platform.

Put all of this aside, I only want to know how to fix my current linking issue with libdazzle. I have no idea to workaround this 'Wrong ELF Class' issue.

This issue is a known problem: https://blogs.oracle.com/solaris/wrong-elf-class-requires-consistent-compiler-flags-v2

It have haunted many developers and scared them from even attempt to make their software compile on Solaris/Illumos.
