Hello,

My linux distro just updated to gcc 4.8.0 (gcc -v output below) and now I get the following compile error related to target.h:

# make V=1 bzImage
make -f scripts/Makefile.build obj=tools/gcc

Thanks,

It looks like while I do not have target.h, there is an article on the web for Darwin and gcc 4.8.0 that indicates it does. Not sure but this is probably not your issue - comments?

# ls /usr/lib/gcc/i486-slackware-linux/4.8.0/plugin/include/target.h
/bin/ls: cannot access /usr/lib/gcc/i486-slackware-linux/4.8.0/plugin/include/target.h: No such file or directory

Thanks for the info and quick reply

Tim

Using your bug report, I copied the 3 files in and was able to build the kernel.

I also reported the bug to slackware

Thanks
