Trying the new 32 bit binaries i get

There are a few issues. With regards to not being able to run 32-bit build in the archive, you may need to do an update to your system. What is the output of
ldd --version? Mine looks like this:
Code: Select all
ldd (GNU libc) 2.14.1

Building errors you see is, one, you are trying to build x86_64 source with 32-bit compiler. You need to make the necessary adjustment in the Makefile [IvanHoeSource]. Second, it appears the developers probably only do their testings in 64-bit OS, so another error you see with bsf is due to:
Code: Select all
static int BSF (uint64 w)
{
uint64 x;
asm ("bsfq %1,%0\n": "=&r" (x):"r" (w));
return x;
}
change it to [RobboBaseLibTester.c]:
Code: Select all
static int BSF (uint64 w)
{
int x1, x2;
asm ("bsf %0,%0\n" "jnz 1f\n" "bsf %1,%0\n" "jz 1f\n" "addl $32,%0\n" "1:":
"=&q" (x1), "=&q" (x2):
"1" ((int) (w >> 32)), "0" ((int) w));
return x1;
}
Another approach is to remove "TESTING_SOURCES = RobboBaseLibTester.c" from the Makefile [RobboBaseLib-0.65a].

I personally was thinking of stopping 32-bit binary builds soon. It is setback for progress. If some had it their way, we would still be on 16-bit architecture. But apparently there is still demand...

. This fix works. It loads just fine without problems in Winboard GUI and is playing against another engine...
