build instructions for ios #95

Do you have a guide how to compile this as a fat library for all required ios architectures (x86_64, armv6, armv7, ...)?

Katko commented 5 years ago

Hey @mlostekk you can use cmake.

brew install cmake
navigate to the dir that you cloned libsamplerate
then follow the instructions here https://cmake.org/cmake/help/latest/manual/cmake-toolchains.7.html#cross-compiling-for-ios-tvos-or-watchos OR make use of this repo https://github.com/leetal/ios-cmake which has already some predefined flags for different iOS Platforms for example the -DPLATFORM=OS64COMBINED will build a FAT library for Device & Simulator arch only for (x86_64, arm64). Regular cmake variables/flags/options can be used as well. Note that the flag mentioned as an example will not include armv7... or any older arch types.

Hey @erikd I was using GitHub repo mentioned above to build libsamplerate but I stumbled upon an issue with some unsigned code. I am sharing below the error message and the environment used. Looks like it is something coming from one of the test files in libsamplerate any ideas how to resolve it?

Error

snr_bw_test is a program in the test suite. I know nothing about iOS dev.
