hidden symbol errors compilingwpa_supplicant with buildroot

[Joel Lindsay]

Yes,

I have built openssl and several other programs with the toolchain.  I have
also built a new toolchain with binutils 2.16.1 and gcc 3.4.2 with the same
error.

I have submitted to buildroot, I have read some reference to the same
problem building with other applications with latest buildroot.

I haven't tested gcc 4.2 with ARM builds, but I have no problems
building and linking wpa_supplicant with gcc 3.4.1 for armeb using
uClibc.

This sounds like a toolchain/configuration issue.. Are you only seeing
this with wpa_supplicant build? Have you tried building something else
that uses the same libraries (namely OpenSSL in this case)?
