Now it failed on not finding <tt>Xcursor.h</tt>. Found and installed the Fedora package for that, continuing…

I looked up the <tt>ucontext.h</tt> source and I think maybe you meant that I should change it to <tt>struct ucontext_t</tt>. I made that change and I’'ll update the moment I know something.

Can you try editing arch/all-linux/kernel/cpu_x86_64.h
Look for
typedef struct ucontext regs_t
And try changing to
typedef ucontext_t regs_t

Thanks! I actually did figure out that fix on my own (for some reason AROS Exec doesn?t come up for me at times) but now I?ve encountered one that I?m not sure what to think of. It?s not a GCC bug:

Seems to be a bug in gcc ..https://mail.coreboot.org/pipermail/coreboot/2017-June/084488.html though im not in a position to fix our patch. for now, the easiest thing to do seems to be to just edit /home/cantanima/Downloads/AROS-20180326-source/bin/linux-x86_64/Ports/host/gcc/gcc-6.3.0/gcc/ubsan.c and change that line ... there should be rules in the build system to re-create the patch for gcc after the modification but im not 100% sure offhand.
