Hi, While I was working on MTTCG I did find it a pain to maintain 2 source trees (one for 64bit and one for 32bit). After speaking to someone about the changes they made to their tests to support out-of-tree builds I thought it might be worth porting to kvm-unit-tests. As it turns out there where a few more warts involved but essentially most of the difficulty is handled by VPATH. The remaining changes deal creating target build directories and handling things like scripts (which are just symlinked to the repo). So far I've tested x86, arm and aarch64 builds but I'll complete the set once people are happy with the general approach. Enjoy, Alex Bennée (8): configure: make it run-able from outside source tree Makefile: ensure build-head works out-of-src-tree Makefile: set VPATH based on SRCDIR Makefiles: use explicit path for including sub-Makefiles Makefile: add explicit mkdir for .o targets Makefiles: handle linking of scripts into build-tree Makefiles: fix up the x86 build include and link paths Makefiles: fix up the arm build include and link paths Makefile | 33 +++++++++++++++++++++++++++------ arm/Makefile | 2 +- arm/Makefile.arm | 2 +- arm/Makefile.arm64 | 2 +- arm/Makefile.common | 15 +++++++++------ configure | 24 +++++++++++++++++------- powerpc/Makefile | 2 +- powerpc/Makefile.ppc64 | 2 +- scripts/asm-offsets.mak | 4 +++- x86/Makefile | 2 +- x86/Makefile.common | 14 +++++++++----- x86/Makefile.i386 | 2 +- x86/Makefile.x86_64 | 2 +- 13 files changed, 73 insertions(+), 33 deletions(-) -- 2.11.0
