We have disabled glog on blackfin external toolchain uclinux sometime 
back [1]. But we are seeing same issue with buildroot based toolchain now.

As elf-fdpic.h is only provided by uClibc and we support only uClibc for 
blackfin, should we disable glog on blackfin ?

Regards,
Rahul

Hello,

[Adding Waldemar in Cc, there's a uClibc bug below.]

No: we should instead fix the bug in uClibc.

Indeed, the following test program:

#include <link.h>
int main(void) { return 0; }

builds fine with the C compiler:

$ ./output/host/usr/bin/bfin-linux-gcc -o toto toto.c 
$

but fails with the C++ compiler:

$ ./output/host/usr/bin/bfin-linux-g++ -o toto toto.c 
In file included from /home/thomas/projets/buildroot/output/host/usr/bfin-buildroot-linux-uclibc/sysroot/usr/include/link.h:78:0,
                 from toto.c:1:
/home/thomas/projets/buildroot/output/host/usr/bfin-buildroot-linux-uclibc/sysroot/usr/include/bits/elf-fdpic.h: In function ?void* __reloc_pointer(void*, const elf32_fdpic_loadmap*)?:
/home/thomas/projets/buildroot/output/host/usr/bfin-buildroot-linux-uclibc/sysroot/usr/include/bits/elf-fdpic.h:94:54: error: invalid use of ?void?
       unsigned long offset = p - (void*)map->segs[c].p_vaddr;
                                                      ^~~~~~~
$

Seems like a bug in the uClibc headers. So I'd prefer that we fix
uClibc rather than disabling glog on Blackfin.

Thanks,

Thomas

I think I have a fix for this and will send it after some verification

Incompatible object files:

file luvi-v2.7.5/jitted_tmp/src/lua/init.lua_luvi_generated.o: ELF 32-
bit LSB relocatable, MIPS, MIPS32 version 1 (SYSV), not stripped

luvi-v2.7.5/CMakeFiles/luvi.dir/src/main.c.o: ELF 32-bit LSB
relocatable, MIPS, MIPS32 rel6 version 1 (SYSV), not stripped

I'm not sure if LuaJIT is able to output object files for MIPS32R6, so
I asked on the LuaJIT mailing list [1]. If not, we have to exclude the
MIPS32R6 architecture from LuaJIT arch support, right?
