pypy: Undefined symbols: "_strnlen"

[ryandesign (Ryan Carsten Schmidt)]

​pypy doesn't build on Snow Leopard because:

	Undefined symbols for architecture x86_64:
	  "_strnlen", referenced from:
	      _opened_profile in vmprof_common.o
	      _vmprof_register_virtual_function in vmprof_unix.o
	ld: symbol(s) not found for architecture x86_64
	clang: error: linker command failed with exit code 1 (use -v to see invocation)

The legacysupport portgroup provides an implementation of strnlen for older systems. Maybe including that portgroup would help here?

Replying to ryandesign:

Presumably it would, although I seriously doubt anyone is making any active effort to make sure that PyPy works on Snow Leopard.

I'll look at this.

[kencu (Ken)]

adding legacysupport

+PortGroup           legacysupport 1.0

+# strnlen
+legacysupport.newest_darwin_requires_legacy 10

does get past the stnlen error, but doesn't fix the build, as soon after, we see this:

[ryandesign (Ryan Carsten Schmidt)]

Interesting, since legacysupport does provide clock_gettime as well, right?

[kencu (Ken)]

Yup. I have no explanation for you at present.
