Sure here is the snippet from the gradle.build file that I am using:
android.ndk {
moduleName = "TestProject"
// Generic stuff
cppFlags += "-O2"
cppFlags += "-std=gnu++11"
cppFlags += "-frtti"
cppFlags += "-fexceptions"
cppFlags += "-fpermissive"
cppFlags += "-DANDROID"
def jniPath = "src/main/jni"
cppFlags += "-I${file(jniPath)}".toString()
file(jniPath).eachDirRecurse { dir ->
cppFlags += "-I${file(dir)}".toString()
}
CFlags += cppFlags
ldLibs += ["android", "EGL","GLESv2", "dl", "log", "jpeg", "png",
"tiff", "z"]
stl = "c++_static"
}
android.buildTypes {
release {
minifyEnabled = false
proguardFiles += file('proguard-rules.txt')
}
}
android.productFlavors {
def libPath = "src/main/jni/prebuilt/"
create("arm7") {
ndk.abiFilters += "armeabi-v7a"
ndk.ldFlags +=
"-L${file(libPath+"libjpeg/libs/armeabi-v7a/")}".toString()
ndk.ldFlags +=
"-L${file(libPath+"libpng/libs/armeabi-v7a/")}".toString()
ndk.ldFlags +=
"-L${file(libPath+"libtiff/libs/armeabi-v7a/")}".toString()
}
create("arm") {
ndk.abiFilters += "armeabi"
ndk.ldFlags +=
"-L${file(libPath+"libjpeg/libs/armeabi/")}".toString()
ndk.ldFlags +=
"-L${file(libPath+"libpng/libs/armeabi/")}".toString()
ndk.ldFlags +=
"-L${file(libPath+"libtiff/libs/armeabi/")}".toString()
}
create("x86-32") {
ndk.abiFilters += "x86"
ndk.ldFlags +=
"-L${file(libPath+"libjpeg/libs/x86")}".toString()
ndk.ldFlags += "-L${file(libPath+"libpng/libs/x86")}".toString()
ndk.ldFlags +=
"-L${file(libPath+"libtiff/libs/x86")}".toString()
}
create("fat")
}
Main issue I was running into is that in our old makefiles we actually had
to add in the libraries by specifying "libtiff", "libpng", etc. here after
linking the actual lib paths it just had to be "tiff", "png", etc. without
"lib" prepended.
