commit cdbd727c20ad7aac7797dc8c95e485e1a4c6901b Author: Richard Henderson <r...@twiddle.net> Date: Thu Jul 7 21:49:36 2016 -0700 build: Use $(AS) for optionrom explicitly Build output (non-verbose): AS optionrom/linuxboot.o cpp: fatal error: '-c' is not a valid option to the preprocessor compilation terminated. cpp: fatal error: '-c' is not a valid option to the preprocessor compilation terminated. CC optionrom/linuxboot_dma.o CC /home/bkamath/dev/workspace/block-2/mothra/output/sp0/targetqga/main.o AS optionrom/kvmvapic.o cpp: fatal error: '-c' is not a valid option to the preprocessor compilation terminated. Steps to reproduce: Using buildroot and overriding qemu version to 2.7.0 Fedora 24, cpp (GCC) 6.2.1 20160916 (Red Hat 6.2.1-2) I tried first just building without the -c option but it hangs indefinitely. Reverting the above listed commit fixes the problem on my platform. I didn't dive much further into this, because this seems like a regression. ** Affects: qemu Importance: Undecided Status: New -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1629483 Title: Build fails on optionrom Status in QEMU: New Bug description: Git pseudo-bisected (focused on optionrom commits) it to this commit. commit cdbd727c20ad7aac7797dc8c95e485e1a4c6901b Author: Richard Henderson <r...@twiddle.net> Date: Thu Jul 7 21:49:36 2016 -0700 build: Use $(AS) for optionrom explicitly Build output (non-verbose): AS optionrom/linuxboot.o cpp: fatal error: '-c' is not a valid option to the preprocessor compilation terminated. cpp: fatal error: '-c' is not a valid option to the preprocessor compilation terminated.
