    @NIvil-Wilson said in How do i use poppler lib in Qt quick application.:

    /usr/local/lib//libpoppler-qt5.so

    I'm sure this is not poppler built for Android.
    You have to provide proper path to the Android version using LIBS.

      Hi,

      I would avoid putting a library like that built for a different architecture/OS in such a generic path. You should store in an explicit dedicated folder.

        after building poppler for android it shows the same errror
        skipping incompatible /usr/local/lib//libpoppler-qt5.so when searching for -lpoppler-qt5.

        This error clearly states that /usr/local/lib//libpoppler-qt5.so is not compatible with what you are building.
        Do

        file /usr/local/lib//libpoppler-qt5.so
        

        and post its output here.

                  Check that file then.

                  Did you ensure that cmake is finding your cross-compiled version and not the one from your system ?

                              Your desktop machine is.

                              I meant the target that runs Android. In any case, if it's ARM, libpoppler was not cross-compiled.

                                  What did you do to build poppler until now ?

                                    sir,
                                    i used the settings given below to cross compile poppler library

                                    if(NOT DEFINED CMAKE_CROSSCOMPILING)
                                    set(CMAKE_CROSSCOMPILING "TRUE")
                                    endif()

                                    set(CMAKE_SYSTEM_NAME Android)
                                    set(CMAKE_SYSTEM_VERSION 21) # API level
                                    set(CMAKE_ANDROID_ARCH_ABI arm64-v8a)
                                    set(CMAKE_ANDROID_NDK /home/nivilwilsonp/Android/Sdk/ndk/21.3.6528147)
                                    set(CMAKE_ANDROID_STL_TYPE c++_shared)

                                      You might want to check here for how they build it for Androïd.
