    Machine: Advanced Micro Devices X86-64

    Is your device running on a x86_64 machine ?

      Your desktop machine is.

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

            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)
