Hi

Eigen fails to compile in Sun sparc box.

Compiler version:
CC: Sun C++ 5.10 SunOS_sparc 2009/06/03
Compilation flags: -xO5 -fns -fsimple=2 -xbuiltin=%all -xdepend=yes -xlibmil -xlibmopt -xtarget=native -mt -library=stlport4 -xcode=pic32
Errors:

Any ideas how it can be fixed?

Thank you, Vlad

yes, you could try to move the definitions into the body class.

Thank you ggael. Your suggestion helped.
I fixed several more bugs along the way (actually not bugs, but quite valid C++ code - stupid SUN CC can not swallow it .

Now I bumped into

Could you help, please.

I think it would be very beneficial to compile Eigen on SUN CC - this will widen Eigen user base (because many big companies don't support gcc and there is no choice, but CC).

Thank you,
