错误：-march =开关坏值 [英] Error: bad value for -march= switch

问题描述

我写了一个Makefile，我无法得到它的工作。我这是应该选择编译到处理器的选项。然而，当我运行制作从它说的命令行：

  tandex @ tandex-P-6860FX：〜/仿真器/任天堂的SDK / 3DS SDK [自制] $化妆
GCC -march = ARM7TDMI -static -fexceptions -fnon叩例外-fstack检查test.c的-c
test.c的：1：0：错误：错误值（ARM7TDMI）为-march =开关使：*** [全部]错误1
 

但在手册页的gcc，它指出ARM7TDMI是一个允许值。我缺少的东西吗？

的Makefile：

 ＃3DS编译生成文件（C）TanDex（TEQ）RunawayFreelancers
＃
的#Version 0.99（阿尔法）对于* nix的设备
＃
#Please请稍后再回来进行第三次SDK#SELECT编译器使用！ GCC推荐！
#FOR SANITY SAKE，与海湾合作委员会采用C文件和CPP文件与G ++
CC = GCC
＃CC = G ++#OBJECTCOPY参考，切勿拆卸
OBJC = objcopy把
OBJREFS = -O二进制#SELECT处理器TUNE IT TO。的ARMv7（任天堂DS）或ARMV9（任天堂的DS
（图形支持））
#OR ARM11内核ARM1176JZ-S和ARM1176JZF-S（3DS处理器？不知道是否正确。请尝试
看看他们的工作？）

解决方案

您很可能不会调用正确的GCC。你似乎被调用系统中安装了gcc，而不是自带的3DS SDK的人。

I wrote a Makefile and I can't get it to work. I have an option which is supposed to select which processor to compile to. However, when I run make from the commandline it says:

tandex@tandex-P-6860FX:~/emulators/nintendo sdks/3DS SDK [HomeBrew]$ make
gcc -march=arm7tdmi -static -fexceptions -fnon-call-exceptions -fstack-check test.c -c
test.c:1:0: error: bad value (arm7tdmi) for -march= switch

make: *** [ALL] Error 1

But in the man pages for gcc, it states that arm7tdmi is a permissible value. Am I missing something?

Makefile:

#3DS Compilation Makefile (c) TanDex (TEQ)RunawayFreelancers
#
#Version 0.99 (Alpha) For *nix Devices
#
#Please Check Back Soon for 3rd SDK

#SELECT THE COMPILER TO USE! GCC RECOMMENDED!
#FOR SANITY SAKE, USE C FILES WITH GCC AND CPP FILES WITH G++
CC=gcc
#CC=g++

#OBJECTCOPY REFERENCE, DO NOT REMOVE
OBJC=objcopy
OBJREFS= -O Binary

#SELECT THE PROCESSOR TO TUNE IT TO. ARMV7 (Nintendo DS) or ARMV9(Nintendo DS
(Graphical Support))
#or ARM11 Core ARM1176JZ-S and ARM1176JZF-S (3DS Processor? Not Sure if Correct. Try
and see if they Work?)
#
#NOTE: DS GAMES REQUIRE BOTH A ARM7 AND ARM9 BINARY. RUN THIS TWICE (ONCE FOR EACH)
#
#UNCOMMENT FOR PROCESOR

PROCESSOR=arm7tdmi
#PROCESSOR=arm946e-s
#PROCESSOR=arm1176jz-s
#PROCESSOR=arm1176jzf-s

#FILES
#
#PLACE ALL OF THE FILES HERE, THAT ARE BEING COMPILED!
FILES=test.c

#SET BIN FILE NAME BASED ON PROCESSOR SELECTED
ifeq($(PROCESSOR),arm7tdmi)\
NAME=ARM7.BIN
ifeq($(PROCESSOR), arm946e-s)\
NAME=ARM9.BIN
ifeq($(PROCESSOR), arm1176jz-s)\
NAME=ARM11.BIN
ifeq($(PROCESSOR), arm1176jzf-s)\
NAME=ARM11.BIN

#CREATE OBJECTS
ifeq($(CC), gcc)\
OBJECTS=$(FILES:.c=.o)
ifeq($(CC), g++)\
OBJECTS=$(FILES:.cpp=.o)

#FLAGS! DO NOT CHANGE THESE!!!!!!!!!!! THAT MEANS YOU!!!!!
#
#FOR THOSE WHO WANT TO KNOW WHAT THESE DO, HERE THEY ARE:
#-mtune=$(PROCESSOR)        FORE THE COMPILER TO TUNE OUTPUT TO THE SPECIFIED
PROCESSOR
#-static            REQUIRED FOR CLEAN BINARY OUTPUT?? (NOT SURE WHAT THIS
DOES, BUT WAS SUGESTED ON A POST ON STACKOVERFLOW)
#-fexceptions           FORCE EXCEPTIONS
#-fnon-call-exceptions      FORCE EXCEPTIONS TO ONLY BE RETURNED BY THE SYSTEM
(MEMORY AND FPU INSTRUTIONS FOR EXAMPLE)
#-fstack-check          FORCE STACK CHECKING (DS / 3DS USE AWKWARD STACK
IMPLEMENTATION)
CFLAGS=-march=$(PROCESSOR) -static -fexceptions -fnon-call-exceptions -fstack-check

ALL:
$(CC) $(CFLAGS) $(FILES) -c
.c.o:
$(OBJC) $(OBJREFS) $(OBJECTS) $(NAME)
.cpp.o:
$(OBJC) $(OBJREFS) $(OBJECTS) $(NAME)

解决方案

You are probably not calling the right gcc. You seem to be calling the gcc installed in your system, rather than the one that comes with the 3DS SDK.
