Question

我试图编译一个示例代码，我在新目录下添加了一个新文件，但我一直遇到依赖问题。我添加了一个文件＆＃34; ipc.c＆＃34;在＆＃34; / interface＆＃34;。我已将源文件添加到＆＃34; srcs＆＃34;并且还使用＆＃34; -I / interface＆＃34;添加了目录。 Makefile如下所示：

#
# ======== Makefile ========
#


include ../products.mak


srcs = main_host.c interface/ipc.c


objs = $(addprefix bin/$(PROFILE)/obj/,$(patsubst %.c,%.o$(SUFFIX),$(srcs)))
libs = $(SYSLINK_INSTALL_DIR)/packages/ti/syslink/lib/syslink.a_$(PROFILE)



MAKEVARS = \
SYSLINK_INSTALL_DIR=$(SYSLINK_INSTALL_DIR) \
PKGPATH=$(PKGPATH)

all:
@$(ECHO) "!"
@$(ECHO) "! Making $@ ..."
$(MAKE) $(MAKEVARS) PROFILE=debug SUFFIX=v5T togs2_host
$(MAKE) $(MAKEVARS) PROFILE=release SUFFIX=v5T togs2_host

install:
@$(ECHO) "#"
@$(ECHO) "# Making $@ ..."
@$(MKDIR) $(INSTALL_DIR)/debug
$(CP) bin/debug/togs2_host $(INSTALL_DIR)/debug
@$(MKDIR) $(INSTALL_DIR)/release
$(CP) bin/release/togs2_host $(INSTALL_DIR)/release

clean::
$(RMDIR) bin


#

$(shell $(MKDIR) -p bin/$(PROFILE))
endif
ifeq (,$(wildcard bin/$(PROFILE)/obj))
$(shell $(MKDIR) -p bin/$(PROFILE)/obj)
endif
endif
endif

# ======== install validation ========
ifeq (install,$(MAKECMDGOALS))

endif
endif

# ======== toolchain macros ========
ifeq (v5T,$(SUFFIX))
CC = $(CS_ARM_INSTALL_DIR)gcc -c -MD -MF $@.dep -march=armv5t
AR = $(CS_ARM_INSTALL_DIR)ar cr
LD = $(CS_ARM_INSTALL_DIR)gcc

CPPFLAGS = -D_REENTRANT -Dxdc_target_name__=GCArmv5T \
-Dxdc_target_types__=gnu/targets/arm/std.h

CFLAGS = -Wall -ffloat-store -fPIC -Wunused -Dfar= $(CCPROFILE_$(PROFILE)) \
-I. -I/interface $(addprefix -I,$(subst +, ,$(PKGPATH))) 

LDFLAGS = $(LDPROFILE_$(PROFILE)) -Wall -Wl,-Map=$@.map
LDLIBS = -lpthread -lc

CCPROFILE_debug = -ggdb -D DEBUG
CCPROFILE_release = -O3 -D NDEBUG

LDPROFILE_debug = -ggdb
LDPROFILE_release = -O3
endif

我一直收到这个错误：致命错误：打开依赖文件bin / debug / obj / interface / ipc.ov5T.dep：没有这样的文件或目录

这就是products.mak的样子：

    RMDIR   = rm -rf
endif

我完全不理解Makefile，因为它是一个代码示例，我只是在扩展。

Answer 1

对于记录：错误“致命错误：打开依赖文件[...]：没有这样的文件或目录”也可能由太长的路径引起。在Cygwin / Windows上发生了一个超过200个字符的路径（没有完全检查）。

Answer 2

搞定了。

需要添加规则来创建输出目录。所以我添加了

ifeq (,$(wildcard bin/$(PROFILE)/obj/interface))
$(shell $(MKDIR) -p bin/$(PROFILE)/obj/interface)
endif

Answer 3

这个makefile非常复杂，所以需要进行一定程度的猜测，但我认为问题在于它不知道如何找到interface/ipc.c。尝试在底部添加此行，看看是否有帮助：

vpath %.c interface

如果没有，我们可以尝试其他一些事情。（如果确实如此，我可以建议一些简化makefile的方法。）
