[Insight-developers] SGI's thread

[Jisung Kim]

Hi,

Do I understand it correctly that if there is sproc on
a system, ITK will use sproc instead of pthread? It
looks like ITK_USE_SPROC value is determined by
CMAKE's    cache value, "CMAKE_USE_SPROC". 

The build command line just above the error message
shows the linker tries to link pthread. Is the error
caused by build environment on that SGI machine?

Just curious. :)

Jisung.
