I get the following error as it tries to compile "po"... This error doesn't exist in 5.2.1. file=./`echo fr | sed 's,.*/,,'`.gmo \ && rm -f $file && PATH=../src:$PATH no -o $file fr.po /bin/sh: no: command not found I did however find an old, closed, GDB bug that indicated linux 2.2.19 did not have this bug. And indeed, on a 2.2.19 box, GDB doesn't exhibit this bug with my test program. Currently I'm working around the issue with a dummy floating point operation at the top of my program. >From: Kevin Buettner >To: Andrew Cagney , bennet > >CC: gdb@sources.redhat.com >Subject: Re: GDB threading/FP bug >Date: Thu, 8 Aug 2002 11:36:59 -0700 > >On Aug 8, 1:34pm, Andrew Cagney wrote: > > > > Some better searching revealed this is a very old bug.
