Is it possible to build libc++ without OS support, e.g. with code such as structured I/O or threads absent or replaced by non-functional stubs?
(based on https://libcxx.llvm.org/BuildingLibcxx.html, I had an optimistic try with -DLLVM_RUNTIME_TARGETS=riscv32-unknown-elf . That fails, but possibly some other set of control macros can achieve this?)
Thanks,
Tom
