This allows us to check: # 1) every interposer was called, and 2) they were called in the # correct order. # TESTROOT = ../.. include ${TESTROOT}/include/common.makefile all-check: all check check: export DYLD_INSERT_LIBRARIES="libfoo1.dylib:libfoo2.dylib:libfoo3.dylib" && ./main all: main libfoo1.dylib libfoo2.dylib libfoo3.dylib main : main.c libfoo.dylib ${CC} ${CCFLAGS} -I${TESTROOT}/include main.c libfoo.dylib -o main libfoo.dylib : foo.c ${CC} ${CCFLAGS} -dynamiclib foo.c -o libfoo.dylib libfoo1.dylib : foo1.c libfoo.dylib ${CC} ${CCFLAGS} -dynamiclib foo1.c libfoo.dylib -o libfoo1.dylib libfoo2.dylib : foo2.c libfoo.dylib ${CC} ${CCFLAGS} -dynamiclib foo2.c libfoo.dylib -o libfoo2.dylib libfoo3.dylib : foo3.c libfoo.dylib ${CC} ${CCFLAGS} -dynamiclib foo3.c libfoo.dylib -o libfoo3.dylib clean: ${RM} ${RMFLAGS} *~ main libfoo.dylib libfoo1.dylib libfoo2.dylib libfoo3.dylib
