How do i use poppler lib in Qt quick application.

[NIvil Wilson]

@SGaist
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)

[SGaist]

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

[NIvil Wilson]

@SGaist
sir, i tried to compile poppler for android arm64-v8a but it always compiled to "x86_64".

[SGaist]

Did you follow the example I linked ?

[NIvil Wilson]

@SGaist
sir, i tried it many times .i changed the architecture and tried many times but it only compile to x86_64 architecture only.I think this is related to configuration mistake that i made cmake compilation process. sorry for my bad english .google translate help me very much these days.

[SGaist]

What did you do exactly for your latest try ?

[NIvil Wilson]

@SGaist
sir, i couldnt understant this line " CFLAGS=-std=gnu99 STANDALONE_EXTRA="--arch arm64" /opt/helpers/build-standalone " which is in the link you given click here

[SGaist]

The line contains the instructions to configure, build and install freetype for Android..
