Subject: Re: be able to break inheritance of LD_LIBRARY_PATH
Date: Fri, 28 Mar 2014 16:27:05 +0400 (MSK)	[thread overview]
Message-ID: <alpine.LNX.2.00.1403281622350.18475@monopod.intra.ispras.ru> (raw)
In-Reply-To: <20140328104208.GZ8221@example.net>

Instead of patching the dynamic loader, you can supply an LD_PRELOAD module
that would remove/modify LD_LIBRARY_PATH appropriately at startup:

#include <stdlib.h>

void __attribute__((constructor))
remove_ld_l_p(void)
{
  unsetenv("LD_LIBRARY_PATH");
  unsetenv("LD_PRELOAD");
}


HTH.
Alexander
