[Qt5] Project doesn't start when trying to instance QtQmlBot

[ruudschouten]

I've have installed AnyRPC and Spix, and have added the lines specified in the readme into my .pro file;

...

# Spix
QT += quick
INCLUDEPATH += /usr/local/include
LIBS += -lSpix -lanyrpc

Building and running this by itself works fine, and doesn't produce any errors. When I create a spix::AnyRpcServer instance with the default port, it also still works fine;

int main(int argc, char *argv[])
{
    ...

    QQmlApplicationEngine *engine = new QQmlApplicationEngine;
    engine->addImportPath("qrc:/");

     // Set up Spix server
    spix::AnyRpcServer server;
    // auto bot = new spix::QtQmlBot();
    // bot->runTestServer(server);
    
    ...
}

but as soon as I uncomment the auto bot = new spix::QtQmlBot(); line, I get the following errors in Qt Creator:

:-1: error: /usr/local/lib/libSpix.a(QtItemTools.cpp.o): in function QByteArray::compare(char const*, Qt::CaseSensitivity) const': QtItemTools.cpp:-1: error: undefined reference to qstrnicmp(char const*, long long, char const*, long long)' :-1: error: collect2: error: ld returned 1 exit status :-1: error: [Makefile:82: mainapp] Error 1

And the following in the compile output

/usr/bin/ld: /usr/local/lib/libSpix.a(QtItemTools.cpp.o): in function `QByteArray::compare(char const*, Qt::CaseSensitivity) const':
QtItemTools.cpp:(.text._ZNK10QByteArray7compareEPKcN2Qt15CaseSensitivityE[_ZNK10QByteArray7compareEPKcN2Qt15CaseSensitivityE]+0x63): undefined reference to `qstrnicmp(char const*, long long, char const*, long long)'

Any help would be appreciated!
