With my modifications to libxc(adding/modifying a few files), I get the following error, but only intermittently. There are no compilation errors in my code. And, also interestingly when I add back the same changes piece-meal and in a different order, this linker error disappears. What could be the reason ? gcc -O2 -fomit-frame-pointer -m64 -fno-strict-aliasing -std=gnu99 -Wall -Wstrict-prototypes -Wno-unused-value -Wdeclaration-after-statement -D__XEN_TOOLS__ -MMD -MF .loadpolicy.o.d -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -Wall -g -Werror -I../../../tools/libxc -I../../../tools/include -I../../../tools/flask/libflask/include -I. -c -o loadpolicy.o loadpolicy.c gcc -O2 -fomit-frame-pointer -m64 -fno-strict-aliasing -std=gnu99 -Wall -Wstrict-prototypes -Wno-unused-value -Wdeclaration-after-statement -D__XEN_TOOLS__ -MMD -MF .flask-loadpolicy.d -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -Wall -g -Werror -I../../../tools/libxc -I../../../tools/include -I../../../tools/flask/libflask/include -I. -L../../../tools/libxc -L../../../tools/flask/libflask loadpolicy.o -L. -lflask -L../../../tools/libxc -lxenctrl -o flask-loadpolicy ../../../tools/libxc/libxenctrl.so: undefined reference to `xc_dom_printf'' collect2: ld returned 1 exit status make[5]: *** [flask-loadpolicy] Error 1 make[5]: Leaving directory `/data/devel/xen-devel/xen-unstable-numa-tip.hg/tools/flask/utils'' make[4]: *** [subdir-install-utils] Error 2 make[4]: Leaving directory `/data/devel/xen-devel/xen-unstable-numa-tip.hg/tools/flask'' make[3]: *** [subdirs-install] Error 2 make[3]: Leaving directory `/data/devel/xen-devel/xen-unstable-numa-tip.hg/tools/flask'' make[2]: *** [subdir-install-flask] Error 2 make[2]: Leaving directory `/data/devel/xen-devel/xen-unstable-numa-tip.hg/tools'' make[1]: *** [subdirs-install] Error 2 make[1]: Leaving directory `/data/devel/xen-devel/xen-unstable-numa-tip.hg/tools'' make: *** [install-tools] Error 2 _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
Also, "make clean" doesn''t help either. The error goes away only on a (trial and error) reordering of my patch set. -dulloor On Thu, Apr 1, 2010 at 1:57 AM, Dulloor <dulloor@gmail.com> wrote:> With my modifications to libxc(adding/modifying a few files), I get > the following error, but only intermittently.

Never mind ! Figured it out. One of my files should go to libxenguest. -dulloor On Thu, Apr 1, 2010 at 2:01 AM, Dulloor <dulloor@gmail.com> wrote:> Also, "make clean" doesn''t help either.
