[mpls-linux-general] Problems when building kernel modules for linux-2.6.8-1.521mpls_1_938a

[Birger <bto...@ex...>]

Hi,

I have difficulties building the kernel, be it from source RPM or when
patching a vanilla 2.6.8 kernel.  On a recent Gentoo system (gcc-3.4.2)
and on a Mandrake 10 system (gcc-3.3.2) when compiling the modules I get

[...]
  CC [M]  net/mpls/mpls_tunnel.o
  CC [M]  net/mpls/af_mpls.o
  CC [M]  net/mpls/mpls_if.o

Any spontaneous idea what went wrong here?  When I try to build MPLS
statically into a kernel image, I also get linker errors (skipped for
now).

Start by not building MPLS or MPLS tunnels as modules.  What errors
do you get when building statically?
