a working solution for me so far:
- install MiniME, do not update anything but compile VMWare-tools using the old gcc and kernel from the MiniME liveCD
- reboot and ensure that everything is working, then update all, and keep the original kernel of course.
when I updated to Fusion3.0.1 some days ago, I thought it would force me to recompile the tools but it didn't and my VM still runs fine with the tools compiled under 3.0.0. But I assume with a fresh Fusion3.0.1 you can do the same steps as outlined above.
Another but untested option for installing the tools on an already updated PCLOS could be to set: export IGNORE_CC_MISMATCH=1
and then try to compile the tools with the new gcc. Maybe that works, don't know, have not tested this yet.
Hopefully we will have a new kernel compiled with the new gcc soon, then this issue should no longer appear.
