Package: libstdc++-riscv64-unknown-elf-dev Version: 14.2.0+7 Hi, I just started working on a bare-metal riscv64 project (PolarFire SoC) It has RV64GC U54 CPU Cores. I have found that compiling c++ project with -march=rv64gc --specs=picolibcpp.specs failes with error:
/usr/include/newlib/c++/14.2.0/cstdint:38:10: fatal error: bits/c++config.h: No such file or directory 38 | #include <bits/c++config.h> I seems to me that the rv64imafdc architecture folders are not available.
