Ya you're right, It should be picked up. For what it's worth, here's our
gradle config, (which ends up passing the correct flags to cmake for building
gnustep):
defaultConfig {
applicationId "com.noodlecake.ssg4"
minSdkVersion 21
targetSdkVersion 28
versionCode 28
versionName "1.0.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
externalNativeBuild {
cmake {
cppFlags "-std=c++14 -frtti -fexceptions
-fconstant-string-class=NSConstantString"
cFlags "-DANDROID -fconstant-string-class=NSConstantString"
arguments "-DCMAKE_VERBOSE_MAKEFILE=ON",
"-DANDROID_STL=c++_static",
"-DANDROID_DISABLE_FORMAT_STRING_CHECKS=TRUE"
}
}
ndk {
// Specifies the ABI configurations of your native
// libraries Gradle should build and package with your APK.
//abiFilters 'x86', 'x86_64', 'armeabi', 'armeabi-v7a',
// 'arm64-v8a'
abiFilters 'armeabi-v7a'
}
