Crosscompile - Right way to cross-compile libs for iOS and Android

Features

• Easy to configure
• Easy to update libs
• Easy to rebuild
• Separate prefix path for every arch

Some libs have different configuration variables hardcoded into header files during build time. We use separate prefix paths for every architecture to load correct headers for each architecture.

Usage

Build libraries

make -j # to build for all platforms
make -j ios # build only iOS versions of libraries
make -j android # build only Android version of libraries

touch downloads/libname && make -j # to rebuild one library and it's dependencies

Change library version

• Change $LIBNAME_VER in download.mk

Add library

It's easy to add more libraries.

• Modify download.mk to download you library and define $LIBNAME_VER and $LIBNAME_DIR.
• Modify build_libs.mk to build your lib.
• Add iOS.mk ios_arch target dependencies.
• Add Android.mk arch target dependencies.

Setup

Xcode

Add following line to your .xcconfig

LIBS_PATH = $(SRCROOT)/../../libs/build/iOS/$(arch)

HEADER_SEARCH_PATHS = $(inherited) $(LIBS_PATH)/include
LIBRARY_SEARCH_PATHS = $(inherited) $(LIBS_PATH)/lib

LIBS = -lcurl -lfreetype -lharfbuzz-icu -lharfbuzz -licuuc -licui18n -licudata -lmsgpackc -lprotobuf -lsqlite3 -lxz "$(LIBS_PATH)/lib/libcares.a"

Where $(SRCROOT)/../../libs is path to this repo on your drive. Libcares linked with full path to force link to static library.

Android Studio

In CMakeLists.txt add following:

get_filename_component(LIBS_DIR "${CMAKE_CURRENT_LIST_DIR}/../../../../libs" ABSOLUTE)
set(ABI_LIBS_DIR "${LIBS_DIR}/build/Android/${ANDROID_ABI}")

include_directories(${ABI_LIBS_DIR}/include)
link_directories(${ABI_LIBS_DIR}/lib)
