Undefined references for Sentry shared object?

Colton

My goal is to include Sentry-Native in an Android Quick project. However, when compiling, I keep getting undefined references for every Sentry function. Even with a minimal project, it produces this error.

Am I doing something wrong here?

I compiled Sentry-Native ahead of time as shared objects and included them in the app with this:

android:!equals(QT_ARCH, armeabi-v7a) {
    ANDROID_EXTRA_LIBS += $$PWD/sentry-libs/$${QT_ARCH}/libsentry_$${QT_ARCH}.so
    DEPENDPATH += $$PWD/sentry-libs/$${QT_ARCH}
    INCLUDEPATH += $$PWD/sentry-libs/include
    DEFINES += USES_SENTRY
}

And at the beginning of the main function I am doing this:

#ifdef USES_SENTRY
    sentry_options_t *options = sentry_options_new();
    sentry_options_set_dsn(options, "...");
    sentry_init(options);

    sentry_capture_event(sentry_value_new_message_event(
      /*   level */ SENTRY_LEVEL_INFO,
      /*  logger */ "custom",
      /* message */ "It works!"
    ));

    // Make sure everything flushes
    auto sentryClose = qScopeGuard([] { sentry_close(); });
#endif

And here are the errors:

..\SentryTest/main.cpp:15: error: undefined reference to 'sentry_options_new'
..\SentryTest/main.cpp:16: error: undefined reference to 'sentry_options_set_dsn'
..\SentryTest/main.cpp:17: error: undefined reference to 'sentry_init'
..\SentryTest/main.cpp:19: error: undefined reference to 'sentry_value_new_message_event'

..\SentryTest/main.cpp:26: error: undefined reference to 'sentry_close'

ANDROID_EXTRA_LIBS is for deploying additional libraries and LIBS for linking to them.

Did you see the example in the documentation to include libraries for all ABIs ?

Hi,

From the looks of it, you don't link to that library.

From what I read, sounded like ANDROID_EXTRA_LIBS would be enough, as it loads the library already. I thought I had tried LIBS in addition before, but trying it again, it compiles, but is now outputting the following:

I zygote  : Late-enabling -Xcheck:jni
W zygote  : Unexpected CPU variant for X86 using defaults: x86
W System  : ClassLoader referenced unknown path:

E AndroidRuntime: 	at java.lang.Thread.run(Thread.java:764)

With this:

LIBS += -L$$PWD/sentry-libs/$${QT_ARCH} -lsentry_$${QT_ARCH}

And alternatively:

LIBS += $$PWD/sentry-libs/$${QT_ARCH}/ibsentry_$${QT_ARCH}.so

This is with an emulator instead of a physical device which may be changing the results (sadly can't be sure, the physical device is busy).

@SGaist I did that originally and it didn't work. Tried again with the minimal project and it works, thank you!

Guess that means the problem is my actual project.
