[Insight-developers] The pow function vs. SGI MIPSPro 7.3.1.3m

[William A. Hoffman]

I have set up the CMakelist files for Insight so that you should not have
to set any flags for the SGI.
The build settings used for rapture are here:

http://www.itk.org/Testing/Sites/rapture.sci.utah.edu/IRIX64-CC-7.3/20050223-0500-Nightly/Notes.html

The flags used can be found here:

IF(CMAKE_SYSTEM MATCHES "IRIX.*")
  IF(NOT CMAKE_COMPILER_IS_GNUCXX)
    SET(ITK_REQUIRED_CXX_FLAGS "${ITK_REQUIRED_CXX_FLAGS} -woff 15,84,1110,1209,1424,1468,3102,3210,3439  -no_auto_include -ptused -no_prelink")
    SET(ITK_REQUIRED_LINK_FLAGS "${ITK_REQUIRED_LINK_FLAGS}  -Wl,-woff15")
  ENDIF(NOT CMAKE_COMPILER_IS_GNUCXX)
ENDIF(CMAKE_SYSTEM MATCHES "IRIX.*")


It could be that you are using a different compiler from SGI that is slightly different.
What version of CC are you using?

CC -version I think.
