hi,
I don’t understand very well some lines of common.mk which is in cuda_sdk.
For example the lines between 202 and 221.
what is the aim of ‘subst’? I suppose that is substitute but why?
what is ‘ar’ and ‘qv’?
Lib/exe configuration
ifneq ((STATIC_LIB),)
TARGETDIR := (LIBDIR)
TARGET := (subst .a,(LIBSUFFIX).a,(LIBDIR)/(STATIC_LIB))
LINKLINE = ar qv (TARGET) (OBJS)
else
LIB += -lcutil$(LIBSUFFIX)
# Device emulation configuration
ifeq ((emu), 1)
NVCCFLAGS += -deviceemu
CUDACCFLAGS +=
BINSUBDIR := emu(BINSUBDIR)
# consistency, makes developing easier
CXXFLAGS += -D__DEVICE_EMULATION__
CFLAGS += -D__DEVICE_EMULATION__
endif
TARGETDIR := (BINDIR)/(BINSUBDIR)
TARGET := (TARGETDIR)/(EXECUTABLE)
LINKLINE = (LINK) -o (TARGET) (OBJS) (LIB)
endif
thank you
