[uClibc]Anyone found the cause...

Tue Jan 7 00:12:24 UTC 2003

Hello gang,
	Yes, I too read through the README file, and have had the link there.  
Depending on what packages you choose to compile, things work great, but as 
soon as you appempt to build a development environment for the "target" 
system (which I use on my development system to ease the compiling of other 
semi-stupid and stupid `./configure` based packages.  It works well, as long 
as I grab buildroot from CVS and change NONE of my settings.

	I am attaching a file that contails the last 5 lines from all config.log 
files so that Erik can take a look at it.  In addition, I have included the 
config file that uClibc should be using.  Out of chance, could this be 
because the uClibc libraries that are being built (it's done twice if you 
build a toolchain & uClibc for the target) are different?  Maybe one is 
getting the proper config and other options (applied via a nifty perl 
command)?  Maybe one of them is actually going to the wrong place, and thus 
the compile of gcc is going awry?  Just a thought.

Thanks all!
Thomas Cameron
