I am not sure what you mean. Isn't this checking whether external/lib exists, as below:<div><br></div><div><div>if test -d $XCRYSDEN_TOPDIR/external/lib ; then</div><div> if test -z "${LD_LIBRARY_PATH}"; then</div>
<div><span class="Apple-tab-span" style="white-space:pre"> </span>LD_LIBRARY_PATH="$XCRYSDEN_TOPDIR/external/lib"</div><div> else</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>LD_LIBRARY_PATH="$XCRYSDEN_TOPDIR/external/lib:$LD_LIBRARY_PATH"</div>
<div> fi</div><div> export LD_LIBRARY_PATH</div><div><br></div><div> if test -z "${DYLD_LIBRARY_PATH}"; then</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>DYLD_LIBRARY_PATH="$XCRYSDEN_TOPDIR/external/lib"</div>
<div> else</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>DYLD_LIBRARY_PATH="$XCRYSDEN_TOPDIR/external/lib:$DYLD_LIBRARY_PATH"</div><div> fi</div><div> export DYLD_LIBRARY_PATH</div>
<div>fi</div><div><br></div><div>Since external/lib will always exist after building xcrysden, DYLD_LIBRARY_PATH will always be set. No, I am not using anything from external/lib, as you can see:</div><div><br></div><div>

</div>No, it is just the opposite. These lines add the<br>
$XCRYSDEN_TOPDIR/external/lib to the DYLD_LIBRARY_PATH (it is implicitly<br>
assumed that external/lib is always there).<br>
<br>
I assume that what is going on is that you have compiled also some<br>
external libraries during xcrysden compilation, which now reside in<br>
external/lib, and probably they are not functioning well. To see which<br>
libraries are loaded run (with original xcrysden script without the<br>
pertinent lines removed) xcrysden as :<br>
<br>
xcrysden -d<br>
<br>
(you will probably need to edit xcrysden script and replace the "ldd"<br>
with "otool -L")<br>
<br>
Let me know what happens.<br>
<br>
