Memory check on macOS 12 Monterey?

Valgrind is not compatible with macOS 12 now, and I tried to add compile flag -fsanitize=address, but got link error:

Undefined symbols for architecture x86_64:
  "___asan_init", referenced from:
      _asan.module_ctor in main.cpp.o
  "___asan_version_mismatch_check_apple_clang_1300", referenced from:
      _asan.module_ctor in main.cpp.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Is there any way to make Valgrind compatible with macOS 12?

Are there any patches via macports or brew that allow you to install Valgrind on macOS 12?

It's all a question of resources. I think that I'm the only active Valgrind dev that uses macOS, but my focus is on FreeBSD. It's a bit of a pity that Apple (market cap of $2.4 trillion at the time of writing) can't commit some relatively small amount of effort to achieve this. There are several IBM engineers contributing (directly for s390 and PPC and indirectly via RedHat).

The changes required to the Valgrind configure scripts are fairly minor.

Try this

AC_DEFINE([XCODE_12_0], 110000, [XCODE_VERS value for Xcode 12.0])

and after line 555

12.*)
            AC_DEFINE([XCODE_VERS], XCODE_12_0, [Xcode version])
            ;;
  • duplicate the case block for kernel version 21.0 (line 526), something like
       # comes after the 20.0) case
       21.*)
      AC_MSG_RESULT([Darwin 21.x (${kernel}) / macOS 12 Monterey])
      AC_DEFINE([DARWIN_VERS], DARWIN_12_00, [Darwin / Mac OS X version])
      DEFAULT_SUPP="darwin20.supp ${DEFAULT_SUPP}"
      DEFAULT_SUPP="darwin10-drd.supp ${DEFAULT_SUPP}"
                  ;;
  • (ignore the suppression version for now)
  • run ./autogen.sh
  • run ./configure
  • run make
  • if that all works run ./vg-in-place yes

Doing the above plus a few more changes for DARWIN_12, I get

I don't have enough reputation to comment on Paul's post. After I made the changes he stated, I got the following error. I am currently on Monterey 12.1 Beta (21C5021h) with Intel i7.
