I am having a terrible time getting any networking to work with a new RedHat Enterprise 6 64 bit install. I am installing on an HP Proliant DL380G7.
I have downloaded the driver - hp-netxtreme2-6.2.23-2.src.rpm from the HP website.
Followed directions and did the following:
1. Build Environment Setup - installed redhat-rpm-config and kernel-devel
2. Installed the source (hp-netxtreme) rpm.
3. Build the Binary RPM - installed rpm-build and ran the following:
rpmbuild -bb /root/rpmbuild/SPECS/hp-netxtreme2.spec
It runs through the build process and near the end I get the following:
make -C /lib/modules/2.6.32-71.el6.x86_64/build SUBDIRS=/root/rpmbuild/BUILD/hpnetxtreme2-6.2.23/obj/default/bnx2-2.0.23b/src modules
expr: syntax error

Error: Bad Exit Status from /var/tmp/rpm-tmp.SdY2z3 (%build)
Step #4 says to check for the existence of kmod-hp-netxtreme2-<flavor> - does not exist.
Checked for the built RPM in /root/rpmbuild/RPMS and the directory is empty.

I have never had to build anything in the Linux environment so have no idea how it is supposed to work nor why I am getting an error message. Can someone help me with this problem so that I can get the network working.
Thanks

That's pretty fundamental. No compiler.That's actually a good way to have a server, as once you are going, you don't want a compiler. Only viruses will go looking for it. But you need one now, along with kernel source, kernel headers. One useful trick I have seen (Kevux.org) is to stuff them all in a separate partition normally unmounted but then mounted as required on /tools or some such. It is easier to drop them in & out than installing/ uninstalling a dozen packages.

Problem didn't end up being an uninstalled network card but a network card that would not connect to a 10/100 network with the defaults installed. I set a fixed IP, GW, NM, and DNS and it would connect to a 1GB network but not the 10/100 MB network. If changed to DHCP it would connect to the 10/100 MB network. Removed the additional lines relating to network management and IPv6 and it connected fine to the 10/100 MB network with fixed IP.
