问题描述
我想一个ARM的CORTEX-A9一个简单的交叉编译(CC):
为了简单起见,多数民众赞成在C- code:
的#include<&stdio.h中GT;
诠释的main()
{
的printf(的Hello World \\ n!);
返回0;
}
在手臂上的本地编译工作正常,并开始与的gcc -o helloworld.c的HelloWorld
,而交叉编译开始与设防赛灵思Linux的gnueabi-GCC helloworld.c -o helloworld_cc
GCC版本:的
NATIV: gcc版本4.6.3(Ubuntu的/ Linaro的4.6.3-1ubuntu5)目标:手臂-Linux的gnueabihf
CC: gcc版本4.6.3(的Sourcery codeBench精简版2012.03-79)目标:手臂,赛灵思Linux的gnueabi
ABI从readelf:的
readelf-NATIV:操作系统:Linux,ABI:2.6.31
readelf-CC:操作系统:Linux,ABI:2.6.16
链接库的 - 编译十字架是静态链接的所以应该不会错过任何一个库:
根@本地:/ TEMP#LDD的HelloWorld
libc.so.6的= GT; /lib/arm-linux-gnueabihf/libc.so.6(0xb6ed8000)
/lib/ld-linux-armhf.so.3(0xb6fce000)
根@本地:/ TEMP#LDD helloworld_cc
不是一个动态可执行文件
问题:的本地PROGRAMM运行正常,消委会始终以结束:
根@本地:/ tmp目录#./helloworld_cc
-bash:./helloworld_cc:没有这样的文件或目录
任何提示,希望我已经包括了足够的信息。
修改
链接为静态的伎俩,但现在文件的大小是巨大的(678KB(CC静态)与4kB的(本机)?为什么缺少的库,即使它说,它不是动态链接?类似的问题:Cross编译使用静态C的hello world为Android臂Linux的gnueabi-GCC
ARM-赛灵思Linux的gnueabi-GCC helloworld.c -o helloworld_cc -static
疗法是LIB 文件夹Linaro的Ubuntu的在一个缺失的环节。这表明了
readelf -a
[请求程序间preTER:/lib/ld-linux.so.3]
把链接的lib / LD-linux.so.3
到的lib / ARM-Linux的gnueabihf / ld-2.15.so
和它的作品。
感谢您的帮助谢尔盖
I'm trying a simple cross compile (cc) for an ARM-CORTEX-A9:To keep things simple thats the c-code:
#include <stdio.h>
int main()
{
printf("Hello World!\n");
return 0;
}
The native compilation on the arm works fine and is started with gcc helloworld.c -o helloworld
whereas the cross compile is started with arm-xilinx-linux-gnueabi-gcc helloworld.c -o helloworld_cc
GCC Version:
nativ: gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5) Target: arm-linux-gnueabihf
CC: gcc version 4.6.3 (Sourcery CodeBench Lite 2012.03-79) Target: arm-xilinx-linux-gnueabi
ABI from readelf:
readelf-nativ: OS: Linux, ABI: 2.6.31
readelf-cc: OS: Linux, ABI: 2.6.16
Linked libs - the cross compiled is static linked so it shouldn't miss any libs:
root@localhost:/temp# ldd helloworld
libc.so.6 => /lib/arm-linux-gnueabihf/libc.so.6 (0xb6ed8000)
/lib/ld-linux-armhf.so.3 (0xb6fce000)
root@localhost:/temp# ldd helloworld_cc
not a dynamic executable
The Problem: the native Programm runs fine, the cc always ends up with:
root@localhost:/tmp# ./helloworld_cc
-bash: ./helloworld_cc: No such file or directory
Any hints, hopefully I have included enough information.
edit
Linking it static does the trick, but now the size of the file is huge (678kB (CC-static) vs. 4kB(native)? Why is it missing libs even if it says it is not dynamically linked? Similar question: Cross compiling static C hello world for Android using arm-linux-gnueabi-gcc
arm-xilinx-linux-gnueabi-gcc helloworld.c -o helloworld_cc -static
Ther was a missing link in the lib
folder Linaro Ubuntu. It showed up with readelf -a
[Requesting program interpreter: /lib/ld-linux.so.3]
Putting the link lib/ld-linux.so.3
to lib/arm-linux-gnueabihf/ld-2.15.so
and it works.
Thanks for the help Sergey
