【已解决】uboot交叉编译出错:gcc/config/arm/lib1funcs.asm:1266: undefined reference to `raise’

【问题】

折腾:

【记录】Ubuntu下用arm-xscale-linux-gnueabi交叉编译uboot

编译最后出错:

即:

xxx/libgcc.a(_dvmd_lnx.o): In function `__aeabi_ldiv0′:

xxx/gcc/config/arm/lib1funcs.asm:1266: undefined reference to `raise’

如图:

gcc config arm lib1funcs.asm 1266 undefined reference to raise

【解决过程】

1.参考:

lib1asmfuncs.asm calls raise unconditionally

但是看不太懂。

2. 参考:

[Buildroot] undefined reference to `raise’ when linking with libgcc

遇到类似问题,但是没说怎么解决。

3.这里也看到讨论:

ibotlog2html for #crosstool-ng

但是还是不知道如何解决。

貌似需要重新build一个???

4.参考:

[Bug c/31798] New: lib1funcs.asm:1000: undefined reference to `raise’

那人是自己手动添加一个了空的raise()函数而使得可以正常编译了。

此处,暂不用这种方法。

5.参考其回复:

[Bug target/31798] lib1funcs.asm:1000: undefined reference to `raise’

说到了:当发生除于0才会出现除的函数,其中会去触发__div0函数

以及,说不是编译器的bug,而需要自己解决:

要么说动实现自己的_div0

要么重新用不同的配置重新去编译交叉编译器。

但是此处:

前者,不太会。

后者,很是麻烦。

所以都放弃。

6.参考:

Re: [nuttx] commit 4573 broke the calypso platform.

其自己解决了:

I fixed locally by linking to src/target/firmware/lib/lib1funcs.S in osmocombb

and doing that:

And linking to it in Make.defs…

但是还是不太想要这种方法。

7.参考:

build uClibc toolchains using Buildroot for GM812x

其是:

  1. 直接修改原始檔,將 raise() 直接回傳 zero. (只是不清楚要改哪,所以跳過)
  2. 直接使用原廠提供的glibc 產生的 nsboot.bin檔。不再產生uClibc 的nsboot.bin。 

此处,也不太会弄。

8.然后看到了

commit 4573 broke the calypso platform

中也有类似的解决办法,但是还是觉得不好。

9.后来看到:

Source object XXX has EABI version 4, but target u-boot has EABI version 0

其中的几个人的解释,比较清楚:

U-Boot is not a GNU/Linux application. However, you’re using the GNU/Linux toolchain to compile it — so the libraries assume the presence of a GNU/Linux C library. In this case, the division routine wants to call "raise" to signal a division-by-zero exception.

People often try to abuse the GNU/Linux toolchain to build U-Boot because they want to use the same toolchain that they use to build the Linux kernel and GNU/Linux applications. But, U-Boot is really a bare-metal application, and, as such, should be built with a bare-metal toolchain, like our "ARM EABI" toolchains. There are often these kinds of problems with U-Boot when moving between different architectures or toolchain versions because the U-Boot source code has tricks to try to make the GNU/Linux toolchain work, and those tricks only work with

particular toolchains.

和:

U-boot explicitly compiles its binaries for ARM with -mabi=apcs-gnu, not EABI, so linking to any EABI compiled libgcc will cause the same error message.

In mainline U-boot currently all libgcc-provided-routines for ARM are also implemented in the lib_arm directory. (yes, it is dirty, but it is done this way for ARM). So, as long as there is an implementation in the lib_Arm directory, nothing will be used from libgcc, and this error will not be seen, even if you use a linux destined compiler.

I noticed that this question was about an very out-dated version of U-boot, namely 1.1.4, so that might be cause some troubles as well.

So, use a proper compiler toolchain (not EABI, but surely a bare metal edition). Several options are possible, you can also use the ARM-ELDK from denx.de

然后去试试后面给出的解决办法:

(1)修改Makefile,改为:

# Add GCC lib
#PLATFORM_LIBS += -L $(shell dirname `$(CC) $(CFLAGS) -print-libgcc-file-name`) -lgcc

(2)再去修改:lib_generic/vsprintf.c

修改为:

#include <linux/string.h>
#include <linux/ctype.h>

#ifdef CFG_64BIT_VSPRINTF
#include <div64.h>
#endif

#include <common.h>

...


#define SPECIAL	32		/* 0x */
#define LARGE	64		/* use 'ABCDEF' instead of 'abcdef' */

#if 0
#define do_div(n,base) ({ \
	int __res; \
	__res = ((unsigned long) n) % (unsigned) base; \
	n = ((unsigned long) n) / (unsigned) base; \
	__res; \
})
#endif

#ifdef CFG_64BIT_VSPRINTF
static char * number(char * str, long long num, int base, int size, int precision ,int type)
#else

结果重新编译,则会导致更多的错误:

10.然后看到之前的一堆人的讨论:

Re: [arm-gnu] In Function __aeabi_ldiv0 : undefined reference to ‘raise’

Re: [arm-gnu] EABI version 5, but target u-boot has EABI version 0

结果是:

此处我用的交叉编译器是arm-xscale-linux-gnueabi,是EABI的

而uboot中对于arm则显式地要求

-mabi=apcs-gnu

即非EABI的。

结果就是:

我的交叉编译器版本太新,而uboot版本太老:1.1.4

所以出了问题。

如果是用来编译比较新的,尤其是最新的uboot,应该就可以了。

11.所以,先去恢复上述的修改再说。

12.然后再想办法,如何去添加自己的raise()或者__aeabi_ldiv0。

但是也不方便改啊。

13.然后是找到了uboot-1.1.4中的,自己的一个.S汇编文件:

board/whgs/lowlevel_init.S

去编辑:

在文件的最后,添加上对应的raise函数:

@add empty raise() to fix (when use new EABI xscale cross compiler to) compile
@error gcc/config/arm/lib1funcs.asm:1266: undefined reference to `raise'
.globl raise
raise:
	nop
	mov	pc, lr

然后再去编译试试,看看能否消除此错误,果然消除此错误了:

【总结】

此处,用交叉编译器arm-xscale-linux-gnueabi(gcc-4.6.0-glibc-2.9)去编译老版本的uboot(1.1.4)而出错:

gcc/config/arm/lib1funcs.asm:1266: undefined reference to `raise’

的原因是:

Uboot是个非GNU/Linux的程序,是个裸程序(bare-metal application);

而交叉编译器arm-xscale-linux-gnueabi是GNU/Linux工具链,是可以正常编译Linux内核等东西的,

但是去编译非GNU/Linux的Uboot的话,就会出现:

当出现被0除的情况时,会调用__aeabi_ldiv0(即eabi版本的__div0),当在GNU/Linux系统中时,其会去触发系统的SIGFPE,进而调用到对应的raise(3)函数。

而此处,由于Uboot不是Linux类程序,没有对应的raise()函数,所以报错找不到。

 

解决办法是:

两种:

1.去用其他对应的配置(估计是用于指定是非GUN/Linux类程序的),重新编译一个新版本的交叉编译器,然后用新的非GNU/Linux的交叉编译器,去编译此旧版本的uboot,即可正常编译

2.修改自己的uboot,加上对应的(随便写个空的)__aeabi_ldiv0或raise函数即可。

此处选用第二种,具体做法:

此处的uboot是whgs的(即配置的时候用的是make whgs_config)

所以找到对应的汇编文件,即:

board/whgs/lowlevel_init.S

在文件最后,添加上

@add empty raise() to fix (when use new EABI xscale cross compiler to) compile
@error gcc/config/arm/lib1funcs.asm:1266: undefined reference to `raise'
.globl raise
raise:
	nop
	mov	pc, lr

然后重新编译,即可。
