Hi,
I'm currently facing an annoying problem when compiling a STATIC binary with gcc5 on ARM architecture, with FreeBSD 10.3.
The problem is some of the softfloat eabi symbols are coming from two sources:
- The libc (/usr/lib/libc.a)
- The libgcc (/usr/local/lib/gcc5/gcc/armv6-portbld-freebsd10.2/5.4.0/libgcc.a)
The firsts duplicated symbols that the linker complain are "__subdf3" , "__adddf3", "__floatsidf", "__extendsfdf2", ...
I don't know how to fix that or, perhaps, use a workaround.
Can you help me ?
Best regards,
--
Alexandre Martins

int main(void) {
float f = 42.42f;
printf("%f\n", sqrtf(f));
return 0;
}
