<div><br><br clear="all">Last night, I portupgraded gettext(it took a long time, though)</div>
<div>and now the problem has disappeared. I tested the example script tetrix.py, it ran smoothly.</div>
<div> </div>
<div>Before portupgrade gettext, I have got a runtime error something like "shared library libintl.so.8 not found"(the system only has the libintl.so.6 that time) when ran PyQT4 script, and this was caused by the lower version of gettext, so I deleted it and reinstalled
gettext0.16.1_1, then libintl.so.6 was replaces by libintl.so.8. But some other programs complained that they can't find libintl.so.6, so I linked libintl.so.8 to libintl.so.6.</div>
<div>At that point, I got the preceding problem(PyQT4 script always crashes).</div>
<div>So I think the problem may be caused by 'PyQt4' mismatches 'gettext'.</div>
<div>And there may be a simple solution :)</div>
<div> </div>
