Compatible with libc++?

[Burnrate]

I've been trying to build a static library for aarch64 using libc++. I've been getting lots of undefined reference errors related to std functions. I've been working on my build process for a few days but can't seem to find anything wrong with it. The build process works for making other static libraries for aarch64 using libc++.

Any reason using libc++ might cause problems?

No idea. The library is tested on libc++ on MacOS and it works there.

Edit 2: We found when we cloned the repo to build it we were copying in some incompatible flags with the set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ... . It still doesn't fit in our build process because we haven't cross compiled from x64 to aarch64 but we can build it and use it on aarch64.

Edit: Still haven't figured this out, my previous post below resulted in a weird unusable success for a while.

In cmake we had to set CXX_EXTENSTIONS OFF and add fuse-ld=lld to the link options for this specific cmake file.

We had already set it up to use the correct compiler and our setup worked for other libraries but 🤷
