py-gssapi: fatal error: 'GSS/GSS.h' file not found

[ryandesign (Ryan Carsten Schmidt)]

​py-gssapi fails to build at least on 10.8:

gssapi/raw/python_gssapi.h:2:10: fatal error: 'GSS/GSS.h' file not found
#include <GSS/GSS.h>
         ^

The ​documentation says GSS is available in macOS 10.14 and later, but that can't be right since it ​built fine on 10.9 and later.

Inspecting our buildbot systems, looks like GSS.h was added in 10.9.

On 10.9:

$ ls /System/Library/Frameworks/GSS.framework/Headers
GSS.h			gssapi.h		gssapi_apple.h		gssapi_krb5.h		gssapi_netlogon.h	gssapi_ntlm.h		gssapi_oid.h		gssapi_protos.h		gssapi_spnego.h

On 10.8:

$ ls /System/Library/Frameworks/GSS.framework/Headers
gssapi.h		gssapi_apple.h		gssapi_krb5.h		gssapi_netlogon.h	gssapi_ntlm.h		gssapi_oid.h		gssapi_protos.h		gssapi_spnego.h

On 10.7:

$ ls /System/Library/Frameworks/GSS.framework/Headers
gssapi.h		gssapi_krb5.h		gssapi_netlogon.h	gssapi_ntlm.h		gssapi_spnego.h

On 10.6:

$ ls /System/Library/Frameworks/GSS.framework/Headers
ls: /System/Library/Frameworks/GSS.framework/Headers: No such file or directory

The port already contains a workaround to use kerberos5 on 10.6 and earlier, but that ​seems to have broken:

Traceback (most recent call last):
  File "setup.py", line 173, in <module>
    GSSAPI_LIB = ctypes.CDLL(os.path.join(main_path, main_lib))
  File "/opt/local/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/ctypes/__init__.py", line 373, in __init__
    self._handle = _dlopen(self._name, mode)
OSError: dlopen(libgssapi_krb5.so, 6): image not found

It should be looking for libgssapi_krb5.dylib not libgssapi_krb5.so.

If the kerberos5 workaround can be fixed maybe it can be extended to 10.7 and 10.8.

If this port can't be made to build on older systems at all anymore, it can be marked as such:

if {${os.platform} eq "darwin" && ${os.major} < 13} {
    known_fail yes
    pre-fetch {
        ui_error "${name} @${version} requires OS X 10.9 or later"
        return -code error "incompatible OS X version"
    }
}

In 90a5ad1ed001099d9f65179c18c420f0497d8cc9/macports-ports (master):

py-gssapi: use kerberos5 on 10.8 and earlier, fixes #60729

[tobypeterson]

the fix is, of course, speculative

Thanks. There's still this issue though:

Thanks, [a2e29ae548c08cd396cee6f2ee2588903a653969/macports-ports] ​fixed it.
