[libc] Skip scanf internals when no file available (#128097) 2025-02-21T20:26:23+00:00 Michael Jones michaelrj@google.com 2025-02-21T20:26:23+00:00 3fad640f06989c1ed5fd5d97868ad9fd807c86dc A temporary fix based on discussions in #128079 Currently, baremetal targets are failing to build because the scanf internals require FILE* (either from the system's libc or our libc). Normally we'd just turn off the broken entrypoint, but since the scanf internals are built separately that doesn't work. This patch adds extra conditions to building those internals, which we can hopefully remove once we have a proper way to build scanf for embedded.

 [libc] Fix scanf cmake for targets without FILE (#128056) 2025-02-20T21:47:45+00:00 Michael Jones michaelrj@google.com 2025-02-20T21:47:45+00:00 5981335d75412977862003816d67d9b01fcd04b6 Another followup fix to #121215 The new cmake wouldn't define the readerat all if the target wasn't GPU or didn't have a definition of FILE. This patch rewrites the cmake to be more general. As a followup, I'd like to make `use_system_file` consistent between /test and /src. Currently in /src it includes the `COMPILE_OPTIONS` and in /test it does not.
