[Lustre-discuss] Anyone built 1.8 or 1.6 on Fedora 12's 2.6.31 yet?

[Stephen Willey]

I've got this morning's b1_8 branch to compile on Fedora 12.  For those interested, here are the steps.

(Disclaimer:  I am not a programmer and the below changes were hacks I made based on far too little knowledge.  If I've done something horribly wrong, please reply saying so).

0) Just remembereed - I happened to symlink /usr/src/linux to kernels/2.6.31.5-127.fc12.x86_64 - Just me being lazy when running configure too many times.

1) /usr/src/kernels/2.6.31.5-127.fc12.x86_64/include/linux/posix_acl.h needs #include <linux/fs.h> adding to it.
I don't know why and this is probably my hackiest hack, but if not, it fails to compile in the configure and causes problems later on.

2) checkout the b1_8 tree and patch it with the attached.

3) sh autogen.sh
4) ./configure --disable-server

5) make rpms CFLAGS=-fno-strict-aliasing
I thought no-strict-aliasing was supposed to be picked up by default for kernel related builds, but I needed to add this.

Once they're built and installed, strangely, the mgc module will not load automatically.  I had to manually modprobe mgc before I could then successfully mount a Lustre FS.  If anyone knows why or if there's a fix, please let me know.

Hope it helps...
