Hello,
I have not used ccache in a while. I just tried building jdk9-dev latest
with ccache and then updating to jdk-9+114 and then running a clean
build. It worked fine. Which version of gcc and ccache are you using? I
use the versions from the official devkit.
ccache 3.2.1
gcc 4.9.2

Hi,
I seem to be running into ccache issues very frequently lately;
basically, every time I do a reconfigure (because the build tells me
to do so after a repo refresh), I'm typically not able to build after
make clean
make images
The build will typically fail somewhere when linking the VM - for
instance the last one I got was this:

I'm usually able to get rid of such issues by running:
ccache -C
Any ideas of what is going on - and why such cleaning step was not
needed before?
