[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] Re: [Xen-devel] [PATCH] libxen compilation fixes
Hi, >... Attached the patch to fix this. I left out the changes to the Makefile, as Keir objected because of the missing gcc-3.3 compatibility (which I can confirm). When I inserted -Wdeclaration-after-statement into my Makefile, everything compiled smoothly without any warnings. I included Ian's prototype fix, too.What would be nice would be to make libxen not throw away provided CFLAGS and, if it's not too far gone down the declaration-after-statement route, fix it to put its declarations at the top of blocks like a good C program. If that's a big job though it's probably not worth the bother.
