Building on Mac

[algobardo]

Hi,
i'm trying to build on Mac,
when i run configure i get

checking if performance counters are usable...
result: no (cannot compile ocamlutil/stats_stubs.c.in)

however stats_stubs.o is generated, but making returns linking error

ld: warning: ignoring file ocamlutil/stats_stubs.o, file was built for i386 which is not the architecture being linked (x86_64): ocamlutil/stats_stubs.o

can you help me to build it ?

This looks like you've built for i386, but you need to build with the CCFLAGS=-arch i386.

There's a note about this in the readme, have you tried using this option? Make sure to do a make clean beforehand.

[algobardo]

Setted CFLAGS and CCFLAGS as in the readme.

I just tried a fresh build on my mac, and got the same error. Using ocaml
4.01.0 (from opam) I was able to progress farther:

Undefined symbols for architecture x86_64:
  "_read_ppc", referenced from:
      _read_pentium_perfcount in stats_stubs.o
ld: symbol(s) not found for architecture x86_64

That's the error I got, and I'm not sure what's happening with it. I will
look into the issue today.

Performance counters are borrowed from CIL, C Intermediate Language. It seems hardware counters are no longer maintained, and thus discarded from redexer as well. (./configure is removed, too.) Please update the repo, and just make again.

I'm trying to compile CEAL and I'm getting the following error, which Kris got above:

Linking bytecode obj/x86_DARWIN/cilly.byte.exe

File "_none_", line 1:
Error: Error while building custom runtime system
make: *** [obj/x86_DARWIN/cilly.byte.exe] Error 2

What was the fix for this?

[kmicinski]

In our case I think the answer was to simply remove the old deprecated
performance counters (that used hardware counters) from redexer and use
software counters instead: that didn't link to this problematic function.
The old advice that fixed this was setting CCFLAGS=-arch i386 in the
configuration.

In general, though, these linking issues seem to be because there is some
weirdness with clang: I'm sorry I can't be more helpful than that though.

Maybe you could track down the hardware counters in CEAL and hack them out
like we did in redexer?
