Hi, I am currently doing a side project where I am trying to make a home made "Alexa" that simply should change my playback device on my computer. I have managed to programatically change my playback device on MSVC compiler in Qt. The next step is to use Porcupine . I am including its header pv_porcupine.h and when compiling I get a lot of errors when using Desktop_Qt_5_14_2_MSVC2017_32bit-Debug compiler. Additional files Picovoice.h My build steps are: Make: jom.exe in ~\qt\build-Project-Desktop_Qt_5_14_2_MSVC2017_32bit-Debug qmake: qmake.exe Project.pro -spec win32-msvc "CONFIG+=debug" "CONFIG+=qml_debug" When I have Make step disabled I managed to get rid of my errors, but I can't change the code, i.e. it does not change upon saving and building. However when I have both qmake and make in the build steps I get 30 errors. My ideas: As stated below, it seems as if there is some issues in the build steps. What I am doing wrong here? Note I am very new to Qt and the whole build process. 08:28:24: Running steps for project Project... 08:28:24: Starting: "C:\Qt\Tools\QtCreator\bin\jom.exe" C:\Qt\Tools\QtCreator\bin\jom.exe -f Makefile.Debug cl -c -nologo -Zc:wchar_t -FS -Zc:rvalueCast -Zc:inline -Zc:strictStrings -Zc:throwingNew -Zc:referenceBinding -Zc:__cplusplus -Zi -MDd -W3 -w34100 -w34189 -w44996 -w44456 -w44457 -w44458 -wd4577 -wd4467 -EHsc /Fddebug\Project.vc.pdb -DUNICODE -D_UNICODE -DWIN32 -D_ENABLE_EXTENDED_ALIGNED_STORAGE -DQT_QML_DEBUG -I..\Project -I. -IC:\Qt\5.14.2\msvc2017\mkspecs\win32-msvc -Fodebug\ @C:\Users\user1\AppData\Local\Temp\main.obj.14556.0.jom main.cpp Project\picovoice.h(27): error C3861: 'visibility': identifier not found Project\picovoice.h(27): error C4430: missing type specifier - int assumed.

My .pro file: TEMPLATE = app CONFIG += console c++11 CONFIG -= app_bundle CONFIG -= qt SOURCES += \ main.cpp HEADERS += \ picovoice.h \ pv_porcupine.h I've asked the Porcupine community but I reckon they have limited resources to help people so I did not get a lot of help from there. Hope you guys might help me better. Thanks, Socke

Hi Im not sure it likes the visual studio compiler. I would try with mingw as it seems the code is tagged for gcc. (for export to lib) (just install the 64 bit Qt mingw. it has compiler included) Also the included DLL have no LIB file so and looking in the examples it seems you must resolve all function calls your self. in the demos (for linux) you see const char *(*pv_status_to_string)(pv_status_t); pv_status_to_string = dlsym(porcupine_library, "pv_status_to_string"); if ((error = dlerror()) != NULL) { fprintf(stderr, "failed to load 'pv_status_to_string' with '%s'.\n", error); exit(1); } So i think you must do the same on windows. for that, you can use QLibrary. https://doc.qt.io/qt-5/qlibrary.html# You can get the symbol name looking at the demos for linux. Good luck !

Yes, I will mark this as solved now.
However, you do know what is the most pain? I just realized that there exists no free open source trigger word detection repository :( apparently, the audio files you use for Porcupine expires after 30 days, in that sense, it's still free but I don't want to manually update my audio files.

Thanks a lot for the help btw.

Victory !

Hmm. That is good to know and a big bummer for you.
So was not such huge joy even you won and got it to work.
On the bright side, you learn alot about linking.
