Makefile depency问题 [英] Makefile depency issue

问题描述

我正在尝试编译一个示例代码，我在新目录下添加了一个新文件，但是我仍然遇到依赖问题。
我在/ interface下添加了一个文件ipc.c。
我已经将源文件添加到srcs，并添加了-I / interface的目录。
Makefile如下所示：

I'm trying to compile an example code where I added a new file under a new directory but I keep getting a dependency problem. I have added a file "ipc.c" under "/interface". I have added the source file to "srcs" and also added the directory with "-I/interface". The Makefile looks as follows:

#
# ======== 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


# 
# 
# ======== rules ========
#
togs2_host: bin/$(PROFILE)/togs2_host
bin/$(PROFILE)/togs2_host: $(objs) $(libs)
@$(ECHO) "##"
@$(ECHO) "## Making $@ ..."
$(LD) $(LDFLAGS) -o $@ $^ $(LDLIBS)



bin/$(PROFILE)/obj/%.o$(SUFFIX): %.h
bin/$(PROFILE)/obj/%.o$(SUFFIX): %.c
@$(ECHO) "###"
@$(ECHO) "### Making $@ ..."
$(CC) $(CPPFLAGS) $(CFLAGS) -o $@ $<


# ======== create output directories ========
ifneq (clean,$(MAKECMDGOALS))
ifneq (,$(PROFILE))
ifeq (,$(wildcard bin/$(PROFILE)))
$(shell $(MKDIR) -p bin/$(PROFILE))
endif
ifeq (,$(wildcard bin/$(PROFILE)/obj))
$(shell $(MKDIR) -p bin/$(PROFILE)/obj)
endif
endif
endif

# ======== install validation ========
ifeq (install,$(MAKECMDGOALS))
ifeq (,$(INSTALL_DIR))
$(error must specify INSTALL_DIR)
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

我不断收到此错误：
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

I keep getting this error: fatal error: opening dependency file bin/debug/obj/interface/ipc.ov5T.dep: No such file or directory

这是产品mak看起来像：

This is how the the products.mak looks like:

#
#  ======== products.mak ========
#

DEPOT = /opt

BIOS_INSTALL_DIR        = $(DEPOT)/bios_6_33_01_25
IPC_INSTALL_DIR         = $(DEPOT)/ti/ipc_1_23_05_40
SYSLINK_INSTALL_DIR     = $(DEPOT)/syslink_2_10_02_17
TI_C6X_INSTALL_DIR      = $(DEPOT)/ti/ccsv5/tools/compiler/c6000
CS_ARM_INSTALL_DIR      = $(DEPOT)/CodeSourcery/Sourcery_G++_Lite/bin/arm-none-linux-gnueabi-
XDC_INSTALL_DIR         = $(DEPOT)/xdctools_3_23_00_32


PKGPATH := $(SYSLINK_INSTALL_DIR)/packages
PKGPATH := $(PKGPATH)+$(BIOS_INSTALL_DIR)/packages
PKGPATH := $(PKGPATH)+$(IPC_INSTALL_DIR)/packages
PKGPATH := $(PKGPATH)+$(XDC_INSTALL_DIR)/packages
PKGPATH := $(PKGPATH)+$


# Use this goal to print your product variables.
.show-products:
    @echo "BIOS_INSTALL_DIR         = $(BIOS_INSTALL_DIR)"
    @echo "IPC_INSTALL_DIR          = $(IPC_INSTALL_DIR)"
    @echo "SYSLINK_INSTALL_DIR      = $(SYSLINK_INSTALL_DIR)"
    @echo "TI_ARM_INSTALL_DIR       = $(TI_ARM_INSTALL_DIR)"
    @echo "TI_C6X_INSTALL_DIR       = $(TI_C6X_INSTALL_DIR)"
    @echo "CS_ARM_INSTALL_DIR       = $(CS_ARM_INSTALL_DIR)"
    @echo "XDC_INSTALL_DIR          = $(XDC_INSTALL_DIR)"


#  ======== standard macros ========
ifneq (,$(wildcard $(XDC_INSTALL_DIR)/bin/echo.exe))
    # use these on Windows
    CP      = $(XDC_INSTALL_DIR)/bin/cp
    ECHO    = $(XDC_INSTALL_DIR)/bin/echo
    MKDIR   = $(XDC_INSTALL_DIR)/bin/mkdir -p
    RM      = $(XDC_INSTALL_DIR)/bin/rm -f
    RMDIR   = $(XDC_INSTALL_DIR)/bin/rm -rf
else
    # use these on Linux
    CP      = cp
    ECHO    = echo
    MKDIR   = mkdir -p
    RM      = rm -f
    RMDIR   = rm -rf
endif

我完全不了解Makefile因为它是一个代码示例，我只是扩展。

I'm not understanding the Makefile completely as it's a code example I'm simply expanding.

任何帮助将是最有帮助的。

Any help would be most helpful.

推荐答案

记录：错误致命错误：打开依赖文件[...]文件或目录也可能是由于路径太长导致的。发生在Cygwin / Windows上，路径超过200个字符（没有检查）。

For the record: The error "fatal error: opening dependency file [...]: No such file or directory" can also be caused by a too long path. Happened to me on Cygwin/Windows with a path that was way over 200 characters (didn't check exactly).
