I have a project that I need to run cross platform. It uses a far few addons:
ofxAppUtils ofxCache ofxCv ofxDelaunay ofxFaceTracker ofxGeo ofxGui ofxHistoryPlot ofxHTTP ofxIO ofxJSONRPC ofxMaps ofxMediaType ofxMSAInteractiveObject ofxNetworkUtils ofxOpenCv ofxOsc ofxPoco ofxSpatialHash ofxSQLiteCpp ofxSSLManager ofxTaskQueue ofxTimingI am using ofxApputils to run scenes and structure (I used it a few times before I liked the ease of making changes). I have the app compiling fine on OSX (Xcode 8) and each of the addons (and their examples) compile fine on windows (well almost). When I try to compile with VS2017 I get some linker errors, but only from ofxHttp and ofxFacetracker. After some testing it seems ofxFacetracker is not compiling on VS2017 (I tried a fresh nightly and redownloaded the addons). The error can be seen here:
The ofxHttp error is different, it compiles fine alone, but it is used by other addons (Basically I am using ofxMaps and ofxJSONRPC and they have some lengthy dependencies). Seemingly every function from ofxHttp gives a linker error like this:
Error unresolved external symbol "public: virtual __cdecl ofx::HTTP::Response::~Response(void)" (??1Response@HTTP@ofx@@UEAA@XZ)So my guess is that VS2017 is for some reason overwriting the obj files during compilation. I do have some errors that may relate to this. Namely that I see this in the build output:
1>obj\x64\Release\Response.obj : warning LNK4042: object specified more than once; extras ignoredThis I a guessing is because of multiple includes and the way VS is dealing with them. Could this be the source of my problems? Or has there been a change in the way VS2017 or the PG is dealing with adding libraries?
Does anyone have some experience with ofxAppUtils? Is there something bad about including stuff in multiple files?
Did anyone see this before?
In general, help…
