            Bug ID: 107629
           Summary: runtime libs don't link on macOS
           Product: gcc
           Version: 13.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: modula2
          Assignee: gaius at gcc dot gnu.org
          Reporter: ro at gcc dot gnu.org
  Target Milestone: ---
              Host: x86_64-apple-darwin11.4.2
            Target: x86_64-apple-darwin11.4.2
             Build: x86_64-apple-darwin11.4.2

The gm2 runtime libs don't link on macOS, e.g. libm2log:

Undefined symbols for architecture x86_64:
  "_DynamicStrings_ConCat", referenced from:
      _FileSystem_Create in FileSystem.o
      _InOut_OpenInput in InOut.o
      _InOut_OpenOutput in InOut.o
      _RealConversions_LongRealToString in RealConversions.o
      _Pad.part.0 in RealInOut.o
      _Strings_Delete in Strings.o
      _Strings_Insert in Strings.o
      ...

and many more.

While libtool knows about the ld option to lift that requirement, there seems
to be no way to activate it.  For now, I've just manually added

LDFLAGS = -Wl,-undefined -Wl,dynamic_lookup

to the various libgm2 Makefiles.  I suspect something along the lines of
libitm/configure.tgt or libsanitizer/configure.tgt will be necessary to handle
this for real.  However, the best way would be to make the libs self-contained,
actually, so the issue would just vanish.

Initial patch

This patch allowed me to finish the libgm2 build on macOS.  As usuual, it
contains
only the non-generated parts.  Again, it would be better to centralize this
to avoid adding to the current duplication with libcc1, libitm, and
libsanitizer.

this is fixed in trunk.
