    Question

    When a particular xxxx_STARTUP_LIBS value, such as WORD_STARTUP_LIBS or SIP2_STARTUP_LIBS, is defined in both $alephe_root/aleph_start and ./aleph_start.private which xxxx_STARTUP_LIBS is used?

    Answer

    The system first reads aleph_start. If an xxxx_STARTUP_LIBS is found, it temporarily stores it. Then it reads aleph_start.private. Any xxxx_STARTUP_LIBS found in aleph_start.private will replace the aleph_start value which has been stored -- *except* when the first xxxx_STARTUP_LIBS aleph_start.private line has a $xxxx_STARTUP_LIBS value. (See Example 1 in Additional Information below.) Then it will *add* the aleph_start.private values those saved from aleph_start.

    Additional Information

    Example 1:

    aleph_start has:

    setenv WORD_STARTUP_LIBS "usm01 usm30"

    and aleph_start.private has:

    setenv ALEPH_LIBS "$ALEPH_LIBS bqr50 bsf50 cav50 cpl50 cps50"
    setenv ALEPH_LIBS "$ALEPH_LIBS dhz50 dip50 div50 diz50 dkp50"

    "echo $aleph_libs" will show: usm01 usm30 bqr50 bsf50 cav50 cpl50 cps50 dhz50 dip50 div50 diz50 dkp50"

    Example 2:


    aleph_start has:

    setenv SIP2_STARTUP_LIBS "usm50"

    and aleph_start.private has:

    setenv SIP2_STARTUP_LIBS "nfg50 wfp50 dip50 nfg50 lea50"


    "echo $sip2_startup_libs" will show: nfg50 wfp50 dip50 nfg50 lea50.
