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
