到目前为止,我已经在我的ubuntu系统上安装了所有交叉编译软件包,但是遇到了问题,需要一些帮助。

这是我需要交叉编译的目标机器。编译时我应该使用哪些标志?
arm-linux-gnueabi-gcc simple.c -march=armv5 -static -o simplev5
arm-linux-gnueabi-gcc simple.c -mcpu=arm926ej-s -static -o simple926
当我运行simplev5或simple926时,显示:
Segmentation fault
按照@Steven P的建议,我检查了文件格式,如下:
user@ubuntu:~/code$ file simplev5
simplev5: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), statically linked, for GNU/Linux 3.2.0, BuildID[sha1]=f0607da1d809a7d98636d76ee0e538fc828e3b65, not stripped
user@ubuntu:~/code$ file simple926
simple926: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), statically linked, for GNU/Linux 3.2.0, BuildID[sha1]=ed1e6fdade02c0d2c985a503dafb6efadd13522f, not stripped
答案 0 :(得分:1)
您很可能拥有正确的编辑,否则您将收到有关无效格式的错误。您可以使用以下方法确认您拥有正确的文件格式:
file simple926
尝试更简单的程序:
int main() { return 123; }
然后,您可以在运行结果代码时检查结果代码以确认它已执行某些操作。
./simple926
echo $?
要解决您的分段错误,您可能需要离开gdb并检查堆栈(回溯)。
