DragonFlyBSD

Bug #2559

Updated by exercitation over 5 years ago

I found that __builtin_popcount is not usable with -pie option for gcc. 

 

 $ uname -a 
 
 DragonFly dragonfly34 3.4-RELEASE DragonFly v3.4.1-RELEASE #7: Wed Apr 24 20:01:27 PDT 2013       root@pkgbox64.dragonflybsd.org:/usr/obj/build/home/justin/src/sys/X86_64_GENERIC    x86_64 
 
 $ cat tst.c 
 
 #include <stdio.h> 
 
 int main(int argc, char *argv[]) 
 
 { 
   
   printf("%d\n", __builtin_popcount(argc)); 
   
   return 0; 
 
 } 
 
 $ gcc -pie tst.c 
 
 /usr/libexec/binutils222/elf/ld.bfd: /tmp//cc2Tj2Mb.o: relocation R_X86_64_32 against `.rodata' can not be used when making a shared object; recompile with -fPIC
