Build libIREERuntime

[wangkuiyi]

Request description

Neither the host compilation step, nor the Android/iOS cross-compilation step produces a runtime library.

The CMakeLists.txt file for the Runtime doesn't seem to have much in it. The build of libIREECompiler is described in the CMakeList.txt file of the Compiler.

Should we build the Runtime library as a static or a dynamic library so that iOS apps can link to it?

What component(s) does this issue relate to?

Runtime

You want to statically link the runtime.

[wangkuiyi]

Yes, I do.

Before I add the static library to my Xcode project, I use the following command line to build it.

libtool -static -o libIREERuntime.a $ALL_ARCHIVES

where ALL_ARCHIVES comes from

du -a ../iree-build-ios/runtime | grep '/lib.*a$' | cut -f 2 | grep -v testing | grep -v testdata

It would be easier if CMake's install target built it.

I've recently been working on this: https://github.com/iree-org/iree-samples/tree/main/runtime-library

Let me know if that is relevant.

Thank you @stellaraccident ! This looks exactly what I am looking for.

I got a warning and an error when I was trying to build the runtime library:

• [runtime-library] CMake configuration of runtime-library causes warnings about CMP0069 iree-experimental#92
• [runtime-library] CMake build of runtime-library failed iree-experimental#93

I ignored the first one and changed a little bit of the code, as described in iree-org/iree-experimental#93, then I got libireert.a. I documented the steps in iree-org/iree-experimental#94.

Is there further work required on this issue?

I think it's as good as it is going to be for now. Could be better but that's future.
