#50100: clang-3.8 fails to support Boost.Python -----------------------------+-------------------------------------- Reporter: akim.demaille@… | Owner: macports-tickets@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 2.3.4 Keywords: C++ | Port: clang-3.8 boost python34 -----------------------------+-------------------------------------- Hi, I'm unsure where I should report this bug: it happens with Boost.Python (1.59) and Clang 3.8. It does not happen with Clang 3.7 and previous, so that's why I send it here. The following program fails to compile: {{{ $ cat foo.cc #include <boost/python.hpp> int main() {} $ clang++-mp-3.8 -I /opt/local/include/ -I/opt/local/Library/Frameworks/Python.framework/Versions/3.4/include/python3.4m foo.cc |& head -50 In file included from foo.cc:1: In file included from /opt/local/include/boost/python.hpp:11: In file included from /opt/local/include/boost/python/args.hpp:25: In file included from /opt/local/include/boost/python/object_core.hpp:14: In file included from /opt/local/include/boost/python/call.hpp:15: In file included from /opt/local/include/boost/python/converter/arg_to_python.hpp:10: In file included from /opt/local/include/boost/python/to_python_indirect.hpp:10: In file included from /opt/local/include/boost/python/object/pointer_holder.hpp:14: In file included from /opt/local/include/boost/python/instance_holder.hpp:11: In file included from /opt/local/include/boost/python/type_id.hpp:14: In file included from /opt/local/libexec/llvm-3.8/bin/../include/c++/v1/ostream:138: In file included from /opt/local/libexec/llvm-3.8/bin/../include/c++/v1/ios:216: /opt/local/libexec/llvm-3.8/bin/../include/c++/v1/__locale:468:15: error: C++ requires a type specifier for all declarations char_type toupper(char_type __c) const ^ /opt/local/Library/Frameworks/Python.framework/Versions/3.4/include/python3.4m/pyport.h:709:29: note: expanded from macro 'toupper' #define toupper(c) towupper(btowc(c)) ^ In file included from foo.cc:1: In file included from /opt/local/include/boost/python.hpp:11: In file included from /opt/local/include/boost/python/args.hpp:25: In file included from /opt/local/include/boost/python/object_core.hpp:14: In file included from /opt/local/include/boost/python/call.hpp:15: In file included from /opt/local/include/boost/python/converter/arg_to_python.hpp:10: In file included from /opt/local/include/boost/python/to_python_indirect.hpp:10: In file included from /opt/local/include/boost/python/object/pointer_holder.hpp:14: In file included from /opt/local/include/boost/python/instance_holder.hpp:11: In file included from /opt/local/include/boost/python/type_id.hpp:14: In file included from /opt/local/libexec/llvm-3.8/bin/../include/c++/v1/ostream:138: In file included from /opt/local/libexec/llvm-3.8/bin/../include/c++/v1/ios:216: /opt/local/libexec/llvm-3.8/bin/../include/c++/v1/__locale:474:48: error: too many arguments provided to function-like macro invocation const char_type* toupper(char_type* __low, const char_type* __high) const ^ /opt/local/Library/Frameworks/Python.framework/Versions/3.4/include/python3.4m/pyport.h:709:9: note: macro 'toupper' defined here #define toupper(c) towupper(btowc(c)) ^ In file included from foo.cc:1: In file included from /opt/local/include/boost/python.hpp:11: In file included from /opt/local/include/boost/python/args.hpp:25: In file included from /opt/local/include/boost/python/object_core.hpp:14: In file included from /opt/local/include/boost/python/call.hpp:15: In file included from /opt/local/include/boost/python/converter/arg_to_python.hpp:10: In file included from /opt/local/include/boost/python/to_python_indirect.hpp:10: In file included from /opt/local/include/boost/python/object/pointer_holder.hpp:14: In file included from /opt/local/include/boost/python/instance_holder.hpp:11: In file included from /opt/local/include/boost/python/type_id.hpp:14: In file included from /opt/local/libexec/llvm-3.8/bin/../include/c++/v1/ostream:138: In file included from /opt/local/libexec/llvm-3.8/bin/../include/c++/v1/ios:216: /opt/local/libexec/llvm-3.8/bin/../include/c++/v1/__locale:474:29: error: expected ';' at end of declaration list const char_type* toupper(char_type* __low, const char_type* __high) const $ }}} It is related to these bits in {{{/opt/local/Library/Frameworks/Python.framework/Versions/3.4/include/python3.4m/pyport.h}}}: {{{ #if defined(__APPLE__) # define _PY_PORT_CTYPE_UTF8_ISSUE #endif #ifdef _PY_PORT_CTYPE_UTF8_ISSUE #include <ctype.h> #include <wctype.h> #undef isalnum #define isalnum(c) iswalnum(btowc(c)) #undef isalpha #define isalpha(c) iswalpha(btowc(c)) #undef islower #define islower(c) iswlower(btowc(c)) #undef isspace #define isspace(c) iswspace(btowc(c)) #undef isupper #define isupper(c) iswupper(btowc(c)) #undef tolower #define tolower(c) towlower(btowc(c)) #undef toupper #define toupper(c) towupper(btowc(c)) #endif }}} My guess is that Python was ready to see these functions being defined _before_ pyport.h being included, but not after, as is now the case. And indeed, if I include {{{<locale>}}} before Boost.Python, it works. So it might be Boost.Python that might need a fix. -- Ticket URL: <https://trac.macports.org/ticket/50100> MacPorts <https://www.macports.org/> Ports system for OS X
