Linux遇到“Argument list too long” 在Linux中使用cp, mv, rm, zip等命令时有时会遇到“Argument list too long”的错误，主要是要进行操作的文件过多导致的。是给其他命令传递参数的一个过滤器，也是组合多个命令的一个工具。为结尾，由于各个系统中分号的意义不同，因此用。是指在指定文件夹下查找指定名称的文件。参数后面是指执行其后面的命令，阅读详情

AI摘要

文章讲述了在使用Makefile编译大型项目时遇到参数列表过长的问题，通过将gcc命令的包含路径写入文件并使用@file方式解决。此外，还讨论了因固件大小超过限制导致的内存溢出问题，通过修改链接脚本增大相应段的大小来解决。

在用Makefile编译大型项目文件时出现了如下错误，提示参数列表过长，gcc 命令后缀是不能超过8000多个字节猜测。

通过查资料gcc 的后缀列表可以放到一个文件中，通过gcc @file 的方式来解决 Argument list too long ,

参考依据：Overall Options (Using the GNU Compiler Collection (GCC))

@file
  Read command-line options from file. The options read are inserted in place of the original @file option. If file does not exist, or cannot be read, then the option will be treated literally, and not removed.
  Options in file are separated by whitespace. A whitespace character may be included in an option by surrounding the entire option in either single or double quotes. Any character (including a backslash) may be included by prefixing
  the character to be included with a backslash. The file may itself contain additional @file options; any such options will be processed recursively.

修改Makfile，将头文件位置重定向到特定的文件中，再gcc @file 去编译：

#-----------------------------------------wl-------------------------add--------------
current_root_dir_temp1 = $(shell pwd)
current_root_dir_cover1 = $(subst \,/,$(current_root_dir_temp1))
current_root_dir1 = $(subst /cygdrive/c,C:,$(current_root_dir_cover1))
$(info "----------------------$(current_root_dir1)") 
current_root_dir2 = "$(current_root_dir1)/iROMXX.ccompincludelist"
$(info "----------------------$(current_root_dir2)") 

#add file path
#VCU APP
A =  -I\"$(current_root_dir)/Source/App/SWC_VCU/AccPed  \"
C := $(shell echo $A >> $(current_root_dir2))
A = -I\"$(current_root_dir)/Source/App/SWC_VCU/AccPedDev \"
C := $(shell echo $A >> $(current_root_dir2))
A = -I\"$(current_root_dir)/Source/App/SWC_VCU/ACCtl_TqDem \"
C := $(shell echo $A >> $(current_root_dir2))
A = -I\"$(current_root_dir)/Source/App/SWC_VCU/ActvDynWhlLd \"
C := $(shell echo $A >> $(current_root_dir2))
A = -I\"$(current_root_dir)/Source/App/SWC_VCU/AntiRollBack \"
C := $(shell echo $A >> $(current_root_dir2))
A = -I\"$(current_root_dir)/Source/App/SWC_VCU/AxleTqPreZrCrsng \"
C := $(shell echo $A >> $(current_root_dir2))

编译文件的位置：

#$(info "------wl------$(ATECH_USER_LINKFLAGS)")
$(info $(LDFLAGS));
.SECONDEXPANSION:
ifneq ($(LINK_LIBRARIES),1)
$(TARGET): $$(OBJS) $(LD_DEPENDENCIES) $(LINKER_COMMAND_FILE) \
           $(ADDITIONAL_OBJECTS_U) $(ADDITIONAL_LIBRARIES_U) \
           $(TARGET_LIBRARY) $(TARGET_RESPONSE_FILE) \
           $(wildcard Makefile.project.part.defines) \
           $(dir $(TARGET))/.dirstamp
    @$(ECHO) "LD         $@"
    $(Q)$(CC_ENV) $(LD) $(LDFLAGS) $(LINKER_OBJS_ARG)       \
                                   $(ADDITIONAL_OBJECTS_U)   \
                                   $(ADDITIONAL_LIBRARIES_U) \
                                   $(SYSLIBS)                \
                                   $(LD_REDIRECT_OUTPUT) \
                                   @$(current_root_dir2) \
                                   $(ATECH_USER_LINKFLAGS)

这样虽然能解决问题，但是只是将.h的路径放到文件中了,.o文件路径没增加到文件中，且这样写法过于啰嗦,如是有了以下修改，利用Makefile中的foreach函数切割对应的环境变量后，重定向到文件中：

#-----------------------------------------wl-------------------------add--------------
current_root_dir_temp1 = $(shell pwd)
current_root_dir_cover1 = $(subst \,/,$(current_root_dir_temp1))
current_root_dir1 = $(subst /cygdrive/c,C:,$(current_root_dir_cover1))
$(info "----------------------$(current_root_dir1)") 
current_root_dir2 = "$(current_root_dir1)/iROMXX.ccompincludelist"
$(info "----------------------$(current_root_dir2)") 

#add file path
#VCU APP
ATECH_INCLUDES := $(foreach dir1,$(ATECH_INCLUDE),$(shell echo $(dir1) >> $(current_root_dir2)))

#$(info "$(B)") 
#-----------------------------------------wl-------------------------end--------------


current_root_dir3 = "$(current_root_dir1)/iROMXX.ccompincludelist2"
#C := $(shell echo $(LINKER_OBJS_ARG) >> $(current_root_dir3))
#WLLL := $(shell for var in echo ${LINKER_OBJS_ARG};do echo var >> $(current_root_dir3);done)
ATECH_OBJECTS := $(foreach dir,$(LINKER_OBJS_ARG),$(shell echo $(dir) >> $(current_root_dir3)))

.SECONDEXPANSION:
ifneq ($(LINK_LIBRARIES),1)
$(TARGET): $$(OBJS) $(LD_DEPENDENCIES) $(LINKER_COMMAND_FILE) \
           $(ADDITIONAL_OBJECTS_U) $(ADDITIONAL_LIBRARIES_U) \
           $(TARGET_LIBRARY) $(TARGET_RESPONSE_FILE) \
           $(wildcard Makefile.project.part.defines) \
           $(dir $(TARGET))/.dirstamp
    @$(ECHO) "LD         $@"
    $(Q)$(CC_ENV) $(LD) $(LDFLAGS) @$(current_root_dir3)     \
                                   $(ADDITIONAL_OBJECTS_U)   \
                                   $(ADDITIONAL_LIBRARIES_U) \
                                   $(SYSLIBS)                \
                                   $(LD_REDIRECT_OUTPUT) \
                                   @$(current_root_dir2) \
                                   $(ATECH_USER_LINKFLAGS)

再次编译后出现下面错误：

gcc region `BMHDO‘ overflowed by xxx bytes

这个原因是固件大小超过了特定的大小，修改链接脚本，本人这里的链接脚本vLinkGen_Template.ld，，这里是通过特定的环境变量LDFLAGS打印出来的。

-T script 是指定ld链接脚本

修改链接脚本，增大BMHDO section 的大小：

MEMORY
{
  DSPR_Core5 : ORIGIN = 0x10000000 , LENGTH = 0x00018000 /* 96 KiB */
  DSPR_Core4 : ORIGIN = 0x30000000 , LENGTH = 0x00018000 /* 96 KiB */
  DSPR_Core3 : ORIGIN = 0x40000000 , LENGTH = 0x00018000 /* 96 KiB */
  DSPR_Core2 : ORIGIN = 0x50000000 , LENGTH = 0x00018000 /* 96 KiB */
  DSPR_Core1 : ORIGIN = 0x60000000 , LENGTH = 0x0003C000 /* 240 KiB */
  DSPR_Core0 : ORIGIN = 0x70000000 , LENGTH = 0x00032FF0 /* 204 KiB */
  Variables_Shared : ORIGIN = 0x70032FF0 , LENGTH = 0x00000080 /* 16 Byte */
  StartupStack_Shared : ORIGIN = 0x70033000 , LENGTH = 0x00009000 /* 36 KiB */
  PFlash0_Boot_reserved : ORIGIN = 0x80000000 , LENGTH = 0x00060000 /* 384 KiB */
  StartupCode_FirstExecInst : ORIGIN = 0x80060000 , LENGTH = 0x00000500 /* 1 KiB */
  CoreExceptions_FirstExecInst : ORIGIN = 0x80060500 , LENGTH = 0x00000600 /* 512 Byte */
  PFlash0_Cached : ORIGIN = 0x80060700 , LENGTH = 0x0029F900 /* 3 MiB */
  PFlash1_Cached : ORIGIN = 0x80300000 , LENGTH = 0x002FFF00 /* 3 MiB */
  PFlash1_Info_reserved : ORIGIN = 0x805FFF00 , LENGTH = 0x00000300 /* 256 Byte */
  BMHD0 : ORIGIN = 0xAF400000 , LENGTH = 0x00000600 /* 512 Byte */
}

至此，完成对整个Makefile大型工程的修改。
