My Lib coredump by Unresolved symbol on HP-UX11.11

polymeta — Wed, 26 Sep 2012 05:04:45 GMT

look at the following info:

my program randomly coredump when it startup, sometimes coredump,somtimes normal.

specially, the position in program when the coredump happen are different.

sqlite3_vsnprintf has been staticly compiled into my lib,why ld say it can't resolved symbol ?

Is it defined in liblog_pa_hpux.sl? Is it exported?

What version of dld.sl do you have? The latest recommended patch is: PHSS_42253

yes, it defined in liblog_pa_hpux.sl but not exported, it is just used by itself

>>What version of dld.sl do you have? The latest recommended patch is: PHSS_42253

you mean that the problem caused by dld.sl ?

Then I'm surprised you get that error.

>you mean that the problem caused by dld.sl?

Most likely, that produces the error and is a very old version.

> what /usr/ccs/bin/ld B.11.18 REL 000922

This is NOT dld.sl. But is over 11 years old.
