Unable to build on macOS with gcc11.5 #1819
Description
Hi, attempting to build cpprestsdk on macOS using gcc11.5 results in build error, originating from macOS system header files.
The main error part:
In file included from /Library/Developer/CommandLineTools/SDKs/MacOSX12.1.sdk/usr/include/Availability.h:136, from /Library/Developer/CommandLineTools/SDKs/MacOSX12.1.sdk/usr/include/time.h:68, from /Library/Developer/CommandLineTools/SDKs/MacOSX12.1.sdk/usr/include/pthread.h:57, from /var/folders/c8/bmp12r395b57hq38dcd6gp5c0000rp/T/a3h5k/cpprestsdk-2.10.18/Release/src/pch/stdafx.h:47, from /var/folders/c8/bmp12r395b57hq38dcd6gp5c0000rp/T/a3h5k/cpprestsdk-2.10.18/Release/src/http/client/x509_cert_utilities.cpp:14: /Library/Developer/CommandLineTools/SDKs/MacOSX12.1.sdk/System/Library/Frameworks/CoreFoundation.framework/Headers/CFUserNotification.h: At global scope: /Library/Developer/CommandLineTools/SDKs/MacOSX12.1.sdk/System/Library/Frameworks/CoreFoundation.framework/Headers/CFUserNotification.h:126:70: error: attributes are not allowed on a function-definition 126 | CF_INLINE CFOptionFlags CFUserNotificationCheckBoxChecked(CFIndex i) API_AVAILABLE(macos(10.0)) API_UNAVAILABLE(ios, watchos, tvos) {return ((CFOptionFlags)(1UL << (8 + i)));} | ^~~~~~~~~~~~~ /Library/Developer/CommandLineTools/SDKs/MacOSX12.1.sdk/System/Library/Frameworks/CoreFoundation.framework/Headers/CFUserNotification.h:127:70: error: attributes are not allowed on a function-definition 127 | CF_INLINE CFOptionFlags CFUserNotificationSecureTextField(CFIndex i) API_AVAILABLE(macos(10.0)) API_UNAVAILABLE(ios, watchos, tvos) {return ((CFOptionFlags)(1UL << (16 + i)));} | ^~~~~~~~~~~~~ /Library/Developer/CommandLineTools/SDKs/MacOSX12.1.sdk/System/Library/Frameworks/CoreFoundation.framework/Headers/CFUserNotification.h:128:69: error: attributes are not allowed on a function-definition 128 | CF_INLINE CFOptionFlags CFUserNotificationPopUpSelection(CFIndex n) API_AVAILABLE(macos(10.0)) API_UNAVAILABLE(ios, watchos, tvos) {return ((CFOptionFlags)(n << 24));} |
It seems that GCC does not support function attributes (API_AVAILABLE, API_UNAVAILABLE) being placed after the function definition. Could this be a known limitation or there is a workaround for this problem?
