I am trying to compile a program with arm-linux-gnueabi-gcc containing neon instructions and executing it over Qemu. The code is,
#include <arm_neon.h>
void NeonTest(short int * __restrict a, short int * __restrict b, short int * __restrict z)
{
int i;
for (i = 0; i < 200; i++) {
z[i] = a[i] * b[i];
}
}
I successfully do it without using -static
flag. But Qemu does not execute/recognize an executable if -static
flag is not used. So when I use -static
to compile and link, I get the following error,
junaid@junaid755:~/code/c$ arm-linux-gnueabi-gcc -static -march=armv7-a -mtune=cortex-a9 -ftree-vectorize -mhard-float -mfloat-abi=softfp -mfpu=neon -ffast-math -mvectorize-with-neon-quad -S neon_test.c

/usr/lib/gcc-cross/arm-linux-gnueabi/4.7/../../../../arm-linux-gnueabi/bin/ld: attempted static link of dynamic object `/lib/ld-linux.so.3'

I have tried the ermine, statifier and other softwares for portable linux applications. But the issue is they work on executables, while in my case the executable generation is causing error.
The problem is solved when i installed arm-linux-gnueabihf-gcc
on my system. Maybe additional packages installed may have resloved the problem. Now I use arm-linux-gnueabihf-gcc
command instead of arm-linux-gnueabi-gcc
. Now the exe file is statically linked. But the problem is not totally solved. On qemu it give segmentation fault now.
