Re: [Fink-users] [EXTERNAL] python27build error

[Hanspeter N. <fi...@sn...>]

We all have the same exact compiler command on 10.14/xcode11.3.1
> gcc -fno-strict-aliasing -Wno-nullability-completeness -DNDEBUG -g -fwrapv -fwrapv -O3 -Wall -Wstrict-prototypes -I. -IInclude -I./Include -I/sw/include -I/sw/include/ncursesw -I/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.15.sdk/usr/include -I/sw/src/fink.build/python27-2.7.18-2/Python-2.7.18/Include -I/sw/src/fink.build/python27-2.7.18-2/Python-2.7.18 -c ./Mac/Modules/_scproxy.c -o build/temp.macosx-10.14-x86_64-2.7/./Mac/Modules/_scproxy.o

that references the SDK-10.15 from Xcode.app. My working python build 
has a warning for _scproxy.c about a header in the unversioned SDK from 
Xcode.app:

/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/System/Library/Frameworks/SystemConfiguration.framework/Headers/SCSchemaDefinitions.h

But error for Jianxin and Luigi refer to the similar header file from 
the SDK-10.14 from the command line tools:

/Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk/System/Library/Frameworks/SystemConfiguration.framework/Headers/SCSchemaDefinitions.h

And the actual error when compiling _scproxy.o immediatel above the 
warning says the __OSX_AVAILABLE_BUT_DEPRECATED_MSG error is in

/Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk/System/Library/Frameworks/Security.framework/Headers/CMSDecoder.h

What's the output of the following (one line) command:

/bin/ls -Fl /Library/Developer/CommandLineTools/SDKs 
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs

I get the following:
```
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs:

```

I'm thinking there's a different symlink in one of your two SDK locations.
