[Vxl-maintainers] vnl_sse compiler error, g++3.4, FreeBSD, 64-bit machine

[Michal S. <so...@cs...>]

Hello fellow vxl-ers,

I ran into the following compiler error when building vnl:

Building CXX object

I have a cvs version of vxl, g++ version 3.4, FreeBSD 6.2. This is a 64-bit
machine.

The compilation succeeds when I make a change in vnl_sse.h to remove
VNL_SSE_FORCE_INLINE (SSE support is turned OFF in CMake):


--- vnl_sse.h   20 Nov 2007 18:57:31 -0000      1.6

Since this happens even when SSE is OFF, should the force inlining block be
conditioned on SSE being ON? Any thoughts?

Thanks.

Michal.
