RE: [Xen-users] Error compiling Xen 2.0.7 on Fedora Core 4 with gcc4

["Chetan Jog" <cjog@xxxxxxxxxx>]

Jorge and Mark,

Thank you for the suggestions. I was able to compile and successfully run Xen 2.0.7 on Fedora Core 4. There was only one other slight detail. I am summarizing here for the benefit of readers.

As Jorge suggested, I verified that gcc-3.2 and compat-gcc-3.2 were installed. I then updated python2.4 config at /usr/lib/python2.4/config/Makefile so that CC variable pointed to gcc32 throughout the document. I used "make CC=gcc32 world" to build Xen.

I then got an error saying "tune=pentium4" is an invalid option; I worked around that by removing that option in /usr/lib/python2.4/config/Makefile.

So far domain creation and migration seems to be working.

Thanks.

Right - Xen 2.0 is never going to support gcc 4, I'm afraid.  The intention is
that Xen 3.0 will do.

Cheers,
Mark
