[OpenWrt-Users] error: C compiler cannot create executables

[Jim Redman]

Robert,

I may have a workaround for this problem.  It seems that it's pretty 
common on a range of distros (FC8, Debian and Ubuntu at least), but only 
with certain targets (atheros, broadcom and NSLU2 - all ARM?):

This post has the solution that seems (so far) to work for me
http://forum.openwrt.org/viewtopic.php?pid=61568

"I compiled from latest trunk (revision > 10000) but in the "advanced 
configuration option" -> "toolchain options" -> "gcc compiler version" I 
set to use gcc 3.4.6 instead of default (gcc 4.1.2)."

Whether the image runs or not is, I suppose, another question...

Jim

PS .configs (current and .old with 4.x) mailed off list, if anyone else 
would like a look at them, please let me know.
