[uml-devel] uml failes to build with pcap enabled

[uml-devel] uml failes to build with pcap enabled

[Alexander Newald]

Hello,

I've tried to use uml with pcap but I fail to build the linux binary.

I used a clean sorce of kernel 2.4.22 from kernel.org and the corresponding
patch from the uml site.

I did:

make menuconfig ARCH=um
make linux ARCH=um

and ended up here...

make[1]: Leaving directory `/home/uml/UML/linux-2.4.22/arch/um/fs'

libpcap is installed as

~/UML/linux-2.4.22> rpm -q -l libpcap
/usr/include/net/bpf.h
/usr/include/pcap-namedb.h
/usr/include/pcap.h
/usr/lib/libpcap.a
/usr/lib/libpcap.so
/usr/lib/libpcap.so.0

/usr/share/doc/packages/libpcap/README.tru64
/usr/share/doc/packages/libpcap/TODO
/usr/share/man/man3/pcap.3.gz

What I'm doing wrong?

Thanks

pcap is one of the lesser-used transports, and requires some build strangeness.

I don't know what's going on here, but I added it to mylist.

Can you try with -6 when it comes out?  I haven't seen that problem here,
but I cleaned up that build a little to make it go away.
