Notes on building VXL for MGH Freesurfer: Here is how v1.13.0 was installed: cd /usr/pubsw/packages/vxl mkdir 1.13.0 ln -s 1.13.0 current cd current unzip <wherever>/vxl-1.13.0.zip mv vxl-1.13.0 src cd src ccmake . <wherever> is the path to the source tarball, which can be found at: ftp://surfer.nmr.mgh.harvard.edu/pub/dist/fs_supportlibs/src or at the VXL homepage. ccmake brings-up the setup utility. All BUILD_ packages should be set to OFF, except for the VNL numerics and utilities packages, and tests. Static libs are built to spare the grief of dealing with LD_LIBRARY_PATH, but freesurfer does not prevent building and using shared libs in a custom installation, like a laptop or home computer. The SSE instructions are used so that 32b platform results match those on the 64b platform (which uses SSE by default). The install path (CMAKE_INSTALL_PATH) is also updated. So these are the things to check in the ccmake screen: BUILD_<something> OFF, except for: BUILD_CORE_NUMERICS ON BUILD_CORE_UTILITIES ON BUILD_SHARED_LIBS OFF BUILD_TESTING ON CMAKE_BUILT_TYPE Release CMAKE_INSTALL_PREFIX /usr/pubsw/packages/vxl/1.13.0 CMAKE_CXX_FLAGS -msse2 -mfpmath=sse CMAKE_C_FLAGS -msse2 -mfpmath=sse Press 'c' a couple times, then 'g' to generate the makefile. Then: make make test make install make clean cd /usr/pubsw/packages/vxl ./fix_perms.csh All tests run during make test should pass (at least they do on the Linux platform). Some platforms, like Mac OS X 10.3.9, have problems building the tests, so those can be set to OFF (ie, re-run ccmake). make install creates /lib /include and /share in CMAKE_INSTALL_PREFIX. make clean deletes the temporary build files. Running the fix_perms script, which exists only at the NMR center, ensures that permissions get reset to where fsdev groups owns and can write all files. Nick 1 March 2010
