Building for ARM fails #162

triplef · 2020-06-04T10:02:40Z

With the latest EH changes the project fails building on both 32- and 64-bit ARM.

As a side-note, it’d be great to have CI for ARM as well. Cirrus CI doesn’t support this yet, but hopefully soon. I couldn’t figure out whether Azure supports this.

The text was updated successfully, but these errors were encountered:

These are supposed to just be copying the state, we should be able to add a COPY_EXCEPTION macro in the two unwind headers to do the right thing here.

For other projects, we're using the Docker + QEMU thing on Azure, which should be fine for this.

I ran into the same issue. Where exactly would I add COPY_EXCEPTION in my working copy, in order to get libobjc2 build on ARMv7?

For the time being, I issued:

sed -e "s|ex->cxx_exception->private_[12] = exceptionObject->private_[12]|;|;s|exceptionObject->private_[12] = ex->cxx_exception->private_[12]|;|" -i ".back" ../eh_personality.c
make install clean
mv ../eh_personality.c.back ../eh_personality.c

I’ve given this a try in #163. Let me know if there’s anything I should change.

I realized that the errors I was seeing on arm64 (undefined reference to cxx_exception_class etc.) were caused by building without a usable C++ runtime. Not sure if that should be a supported use case (I wouldn’t need it) – if not maybe "No useable C++ runtime found" should be an error.

For other projects, we're using the Docker + QEMU thing on Azure, which should be fine for this.

Good point. I realized it’d be great to specifically test building for Android, which should work fine on CI using cross-compilation. I’ll look into this once libc++abi support lands.

This still does not compile on ARMv7 (s. error log below). For the time being I got it to build with:

sed -e "s|COPY_EXCEPTION\(.*\)||" -i ".back" ../eh_personality.c

Which compiler are you using? I’m not sure but maybe it requires to specify the nested structs with something like struct _Unwind_Exception.unwinder_cache.

I see another issue now. The statically built libobjc2.a(-DBUILD_STATIC_LIBOBJC=ON) does not work anymore. On ARMv7 it simply refuses to link. Shall I open a new issue report about this?
