Are there some artifacts left behind from the before times, that let things work as they used to? I don't think the steps I'm using are particularly weird. If I check out v11.1.0, I get... [qemu]# rm -rf build/ [qemu]# mkdir build [qemu]# cd build/ [build]# ../configure ...snip... [build]# cd pc-bios/s390-ccw/ [s390-ccw]# make -Wno-stringop-overflow detected -fno-stack-protector detected -Wno-array-bounds detected -Wno-gnu detected -march=z900 detected Assembling start.o Compiling main.o ...etc... Compared to the error I'd mentioned earlier. The best I can do to reproduce your behavior is to do the above on v11.1.0, checkout master, re-configure, touch /path/to/qemu/build/pc-bios/s390-ccw/Makefile, and then redo the make. But if I do a make clean, or throw away my build directory and re-do everything, I end up failing again. Having said all that, I'll happily test what you have. Thanks, Eric
