Windows Embedded Compact 2013 support #38

Closed apolukhin closed 7 years ago

apolukhin commented 7 years ago

In https://github.com/boostorg/dll/issues/10 it was discovered that Windows Embedded Compact 2013 is currently not supported. That leads to errors like:

1>C:\Program Files (x86)\Vector Vrtp\SDKs\WEC800_VRTP_SDK\sdk\Inc\kfuncs.h(415): error C2061: syntax error : identifier 'LPVOID'
1>C:\Program Files (x86)\Vector Vrtp\SDKs\WEC800_VRTP_SDK\sdk\Inc\kfuncs.h(563): error C2146: syntax error : missing ';' before identifier 'LockResource'

Inclusion of #include <windows.h> leads to errors with linkage:

1>D:\libraries\boost_1_63_0\boost/detail/winapi/dll.hpp(58): error C2375: 'LoadLibraryW' : redefinition; different linkage
1>          C:\Program Files (x86)\Vector Vrtp\SDKs\WEC800_VRTP_SDK\sdk\Inc\winbase.h(1261) : see declaration of 'LoadLibraryW'
1>D:\libraries\boost_1_63_0\boost/detail/winapi/dll.hpp(100): error C2375: 'VirtualQuery' : redefinition; different linkage
1>          C:\Program Files (x86)\Vector Vrtp\SDKs\WEC800_VRTP_SDK\sdk\Inc\winbase.h(1013) : see declaration of 'VirtualQuery'

WINAPI is defined in the following way:

#elif (_MSC_VER >= 800) || defined(_STDCALL_SUPPORTED)
#define CALLBACK    __stdcall
#define WINAPI      __stdcall
#define WINAPIV     __cdecl
#define APIENTRY    WINAPI
#define APIPRIVATE  __stdcall
#define PASCAL      __stdcall
#else

Defining BOOST_USE_WINDOWS_H helps to workaround all the issues.

Unless you can provide a patch, I don't think I'll be able to fix it.

Supporting WEC would require me to download and install the SDK, and then port all definitions in Boost.WinAPI to it. This is currently too much time for me to spend.

I'm going to close this ticket for now and flag WEC as unsupported beyond the BOOST_USE_WINDOWS_H mode. If I have time in the future I might end up doing a proper port.

@Lastique, don't close the ticket, I'll provide a patch.

@frederich, any news on the patch?
