Linux installation notes

  • Starting from SItoA 3.6.0  (which uses Arnold, the minimum requirements for Linux have been raised to the equivalent of RHEL/CentOS 6 for glibc and libstdc++. However, Softimage ships with a legacy libstdc++ that is put in the LD_LIBRARY_PATH and that hijacks the system one, making it impossible to load the Arnold DSO. To fix this, one solution is to preload the system libstdc++ before launching Softimage:


    export LD_PRELOAD=/usr/lib64/


    Another solution is to remove the libstdc++ from the Softimage install and let the system one take over, for example:
    cd my_softimage_install/Application/bin
